Length 1.20 inches; cylindrical, rather slender, two warty elevations on the dorsum of joints 5 and 12, elsewhere the piliferous spots scarcely perceptible, except for the single hair that arises from each. Color green; a dorsal pale yellow line, bordered on each side on joints 3 and 4 by a purple line; outside this a pale yellow stripe that diverges on joint 2, gradually diverging again on joints 4, 5 and 6, where it reaches below the usual region of the subdorsal line, extending from this back to joint 11, from which it gradually converges to the elevations on joint 12, touching these on the outside, the diverging and converging referring to the stripes on both sides of the body. These stripes send more or less prominent deflections down the sides of joints 7 and 10. In some examples the space between these stripes and the dorsal line contains a pale whitish stripe each side of the dorsal; the deflections, and a little on joint 5 and the elevations, are reddish purple.

Leeches were used in the treatment of many pediatric conditions until relatively recently. Many physicians prescribed leeches, especially in the treatment of the purported symptoms caused by teething. William Moss,1 for example, advised applying two or three leeches at one time on the foot or heel of teething infants where "bleeding is a remedy much to be depended on when the symptoms of heat, fever, drowsiness, and startings are urgent." The following is an excellent description of the indications for leeching in children, as given by Dr. James Kennedy in 1825: Leeching, so as to abstract blood from a particular part sustaining inflammation, fulness, or pain, is very useful in many diseases especially those of children. . . . When the leech is of the right or medicinal kind, its body has a blackish brown colour, marked on the back with six yellow spots, and edged with a yellow line on each side:—these spots, however, as well as the lines, grow faint and almost disappear at certain seasons. . . . The mouth forms, as it were, the body of a pump and its tongue the sucker; and, by the working of this . . . mechanism, the blood is made to rise up into the conduit which conveys it to the animal's stomach. . . . Leeches may be employed in every case where topical bleedings are required, or where venesection cannot be performed. Before applying them, all the parts should be carefully washed;—first, with hot water and soap, for the purpose of removing, as much as possible, the particles of the cutaneous excretion which the leech instinctively dislikes, especially if impregnated in any degree with the odour of medicine;—and secondly, with milk and water as warm as can be endured, with the object of stimulating the superficial vessels and filling them with red blood.

Cestrus itatiensis sp. nov., from the Brazilian Atlantic Forest, is described and illustrated. This is the southernmost record for the genus and the first record in Brazil. The new species is characterized by having the body reddish brown; a narrow yellow stripe along eye margin on supra-clypeal area, reaching briefly the supra-antennal area; transverse carina of propodeum complete and stout; postpetiole and T2–8 progressively dark brown towards apical margin in a somewhat triangular pattern; and apex of dorsal valve of ovipositor with nine distinct teeth. Extensive sampling suggest this is a rare species.

The Body ◽  

Length .50 of an inch, elliptical, as is the usual shape of the Lymacodes group, nearly .20 of an inch high and about the same width. The dorsum has four lines of purplish black alternating with white, and bordered outside with yellowish white or pale yellow. The region of the subdorsal line is a bright vermillion ridge with yelrowish white tubercles arising from joints 2, 3, 4, 7, 10 and 12, those on joint 2 moderately short, but those on joints 4 to 12 are nearly one fourth of an inch long; all of them spiny. There are short bunches of spines on the intervening joints, as it were representatives of missing tubercles. In the subdorsal space are four scarlet lines alternating with lines of yellowish white, the middle yellowish line instead of being continuous, consists of alternate blotches of vermilion and yellowish white. The substigmatar line is vermilion, bordered as the subdorsai with pale yellow, and this also has its row of yellowish white spiny tubercles, each about one sixteenth of an inch long. Below this is a single dark purple line bordered each side with a lighter shade, and below this a vermilion line or rather a series of tubercles without spines in place of the prolegs. Legs 6, no prolegs, but the under side of the body consisting of a muscular pad upon which the insect glides along instead of walking. Head brown, retractile when at rest into the joint back of it.

We describe a new species of polyclad flatworm, Pericelis flavomarginata sp. nov., from the intertidal and subtidal zones along localities on the Pacific coast of Japan. Pericelis flavomarginata sp. nov. is characterized by i) the dorsal surface of the body fringed by a lemon-yellow line except for the tip of tentacles, with a narrow brown midline running from the anterior edge of the body to the posterior end of the pharynx, ii) the pair of marginal tentacles with the tips extending and tapering, and iii) the presence of a common gonopore. Our molecular phylogenetic analysis revealed that selected Pericelis species were divided into two clades, each of which may be agreed with a characteristic dorsal color pattern. Additionally, we report an observation on the feeding behavior of P. flavomarginata sp. nov. on the polychaete Iphione muricata (Savigny in Lamarck, 1818).

Abstract Background: Pumpkin is an important non-saline economic vegetable, salt stress often restricts the growth of pumpkin roots and the transportation and balance of mineral ions in the body. Oligopeptide transporter (OPT) plays an important role in transporting small peptides, secondary amino acids, Glutathione and minerals. However, information about the family of OPT in pumpkin is still limited. Results: In this study, 45 OPT transporters were identified from two cultivated species of Cucurbita moschata and Cucurbita maxima. Phylogenetic analysis showed that these OPT families were divided into two evolutionary branches: OPT clade and yellow stripe-like (YSL) clade. All of these genes contain the typical structure of OPT superfamily, OPT clade contains 12 conserved motifs, while the YSL clade contains 7 conserved motifs. There are tandem gene replication events on chromosomes 13, 16 and 18 of Cucurbita moschata and Cucurbita maxima, and 17 and 18 pairs of genes were collinear with Arabidopsis thaliana, respectively. Promoter element analysis showed that there were many cis-acting elements in the upstream promoters of these genes in Cucurbita moschata and Cucurbita maxima, which responded to 10 kinds of stress, especially hormones (MeJA and ABA) and hypoxia. The expression patterns based on transcriptome data sources showed that some OPT genes were organ-specific and tissue-specific, which might be involved in plant functional development. Transcriptome and qRT-PCR verification tests showed that CmoYSL7, CmaOPT15 and CmaYSL7 of Cucurbita moschata and Cucurbita maxima might play a key role in regulating the balance of metal ions between leaf mesophyll and leaf veins under salt stress. Conclusions: Overall, the data obtained from our study contribute to a better understanding of the complexity of the OPT genes family in pumpkins. These results will provide new insights into the mechanism of salt tolerance and the structure and function of OPT genes in pumpkin.

ABSTRACT              Butterflies are one of the natural resources and are part of the biodiversity that must be preserved. Efforts to patronize bird wing butterflies (Ornithoptera goliath) are an alternative in the preservation of bird wing butterflies which are presently endangered. Efforts to preserve bird wing butterflies (Ornithoptera goliath) have not been widely carried out and there is no data on the breeding stage because information about butterflies is not widely known. This study aims to analyze the stages of development or life cycle (from caterpillars to cocoons) bird wing butterflies (Ornithoptera goliath) in the buffer zone of the Arfak Mountains Nature Reserve. The method used is descriptive method with direct observation techniques in the field. The characteristics of the morphological structure of the young caterpillar recorded were small and short body shapes, the initial length is 0.55 cm and diameter is 0.15 cm, the whole body was blackish brown, there was a whitish yellow stripe on the back. There are soft spikes in all parts of the body and a pair of orange antennas in the head, head and abdomen in black. The morphological structure characteristics of adult caterpillars are elongated oval body 4,15 cm long and 1.25 cm in diameter. The head and abdomen are black, the whole body is black, there are soft black spikes all over the body, on the dorsal mid-body there is a white line, a pair of orange antennas on the head. Bird wing butterflies (Ornithoptera goliath) have a life cycle to cocoon for 48 to 51 days.   ABSTRAK             Kupu-kupu merupakan salah satu sumberdaya alam dan merupakan bagian dari keanekaragaman hayati yang harus dijaga kelestariannya. Usaha penagkaran terhadap kupu-kupu sayap burung (Ornithoptera goliath) merupakan alternatif dalam pelestarian kupu-kupu sayap burung yang saat ini mulai terancam kelestariannya. Usaha pelestarian kupu-kupu sayap burung (Ornithoptera goliath) belum banyak dilakukan serta belum ada data informasi tahap perkembangbiakannya disebabkan informasi mengenai kupu-kupu belum banyak diketahui. Penelitian ini bertujuan untuk menganalisis tahapan perkembangan atau siklus hidup (dari ulat hingga kepompong) kupu-kupu sayap burung (Ornithoptera goliath) di  daerah penyangga Cagar Alam Pegunungan Arfak. Metode yang digunakan adalah metode deskriptif dengan tehnik pengamatan langsung di lapangan. Karakteristik struktur morfologi ulat muda yang direkam adalah bentuk tubuh kecil dan pendek, dengan ukuran ratarata 0,55 cm dan diameter 0,15 cm, seluruh tubuh berwarna cokelat kehitaman, terdapat corak bergaris kuning keputihan pada bagian punggung.  Terdapat duri-duri lunak di seluruh bagian tubuh dan sepasang antena berwarna orange di bagian kepala, Kepala dan abdomen berwarna hitam. Karakteristik  struktur  morfologi  ulat dewasa adalah tubuh lonjong memanjang, panjang  4,15 cm dan diameter 1,25 cm. Kepala dan abdomen berwarna hitam, seluruh tubuh berwarna hitam, terdapat duri-duri lunak hitam di seluruh tubuh, pada bagian dorsal mid-body terdapat garis berwarna putih, sepasang antenna berwarna orange dibagian kepala. Kupu-kupu sayap burung (Ornithoptera goliath) mempunyai siklus hidup hingga kepompong selama 48 hingga 51 hari.

Aristotelia Youngella, sp. nov.—Head. antennæ, palpi, thorax abdomen and legs shining iridescent green. Basal half of front wing and outer half along costa black or very dark brown, heavily overlaid with iridescent green. The dark basal half is outwardly margined by the black ground colour, owing to absence of the iridescent scales at this point. All the outer half of wing, except the dark costal streak, is dull ochreous, inwardly margined by a pale yellow line, the latter adjoining the dark line of ground colour outlining the basal half.

Nineteen species of the neotropical gobiid genus Elacatinus are currently known from the western Atlantic, six of which are closely associated with sponges. Elacatinus colini is described as a new species of sponge-dwelling goby from Belize and Islas de la Bahía, Honduras. Formerly regarded as a color variant of E. xanthiprora (Böhlke & Robins) from Florida, it is differentiated principally by having a white instead of bright yellow stripe on the body, and 17 or 18 vs. 19 or 20 pectoral-fin rays. A second new species, E. serranilla, also formerly identified as a color form of E. xanthiprora, is described from three specimens from the Serranilla Bank in the Caribbean Sea (15°50’N, 79°50’W) and one from Jamaica (formerly a paratype of E. xanthiprora). It is distinct in having 10 dorsal soft rays (vs. 11 or 12 for E. xanthiprora), a bluish white dorsolateral stripe and median rostral band, longer dorsal-fin spines, and longer dorsal and anal soft rays. Elacatinus xanthiprora is presently known from Dry Tortugas (type locality) north to Miami in the Atlantic, and north to 28°41’N, 83°45’W on the Gulf coast of Florida, where the largest specimen (ANSP 148926, 43.1 mm SL) was collected at a depth of 26 m. Specimens off the east coast of Nicaragua in 27 m, and from nearby Isla de Providencia in 3–13 m, also previously identified as E. xanthiprora, probably represent two different undescribed species. Additional collection of specimens from the latter two localities is recommended for details of life color and DNA analysis.

The following is a summary of our studies on population of head lice, adults and nits.1. Out of a total of 8702 adult lice, the male population comprised 2031. The gross infestation rate per head was 129.9 and the maximum number found on a single head was 1434. A disproportion in the distribution of the two sexes was a marked feature.2. Patients below the age of 11 showed a lower infestation rate than those above this age, and short-haired individuals were more heavily infested than long-haired ones.3. Frequent combing of the hair and the use of oil did not seem to dislodge the adults or to prevent the females from laying eggs.4. The maximum larval count on a single head was found to be 4260, the average number of larvae per single head was 418·8, and 9 to 1 was the maximum proportion of larvae to females.5. The maximum number of nits on a single hair was found to be 17 and 5·06 was calculated as the average number per hair.6. Treatment with kerosene and pyrethrum killed all the lice and nits, and reinfestation did not occur.7. The infestation did not spread to healthy patients in the hospital ward; it is thought that the poor migratory habits of lice are responsible for this.8. From studies on the reinfestation of an individual after treatment it is concluded that head-lice cannot establish themselves on any part of the body except the head, and if their access to the head is prevented, the lice will not survive for more than 24 hr.
