First Time

AbstractFirst instars of 93 North American species of mosquitoes are studied and 56 are illustrated, 41 for the first time. Generic differences are well marked in this instar and nearly all species are separable.Two keys to the 11 North American genera are presented; the first is constructed to show similarities between first and later instars. Each genus is described and keyed to species, and notes are given on each species. A supplementary key to the species of the southeastern states is designed for the use of a binocular microscope with magnification up to 60 ×.Specific and generic differences are as well marked in the first as in the fourth instar. Identifications are as easy or as difficult in the first as in the fourth instar, though usually based on different characters.An expanded key to the North American species of Aedes, incorporating those previously treated by Bohart and by Price, is attempted. The key reveals several species complexes which have not been discerned from other stages of the life cycle, namely, Aedes canadensis, nigromaculis, punctor, stimulans infirmatus and trivittatus.A key to the first instars of the 37 species of the world-wide Anophelinae is presented, on the basis of published descriptions and figures of the exotic species.

Cirsium Undulatum

The morphology and specific differences of Cirsium undulatum (Nutt.) Spreng. and of C. flodmanii (Rydb.) Arthur are described and their Canadian distributions are reported in detail. The chromosome numbers are C. undulatum f. undulatum and f. album Farwell, 2n = 26; C. flodmanii f. flodmanii and f. albiflorum D. Löve, 2n = 22. The origin of four North American species of Cirsium that do not follow the world-wide base number 17 is discussed; it is postulated that reduction in number has occurred by translocations. The chromosomes of species with reduced numbers are larger than those of the unreduced species but the total length of the chromosomes of both groups is approximately the same.

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

All macropterous species of Aptilotus Mik are keyed, with descriptions of two new macropterous North American species, Aptilotus pogophallus and A. nigriphallus. New distributional records are given for other North American species, and brachyptery is noted for the first time in A. luctuosus (Spuler). Four new macropterous species of Aptilotus (glabrifrons, spinistylus, rufiscapus, and binotatus are described from Nepal. The relationships between the North American and Nepalese species are discussed. Minocellina Papp is synonomized with Aptilotus, and the two species formerly in Minocellina, A. thaii (Papp) and A. besucheti (Papp), are thus given as new combinations. Limosina carbonicolor Richards, from Ethiopia, is redescribed and transferred to Aptilotus.

AbstractThe Elachista tetragonella group is redefined, its limits extended to include the genus Biselachista Traugott-Olsen & Nielsen, 1977. The North American species of the tetragonella group are described and illustrated, and a key is given to the males. 19 species are recognized in the Nearctic region, including 12 new species: Elachista pyrrha (Alberta), E. absaroka (Wyoming), E. calusella (Florida), E. beothucella (Newfoundland), E. glenni (Illinois), E. cerasella (Nebraska), E. serra (Labrador), E. huron (Quebec), E. vinlandica (Newfoundland), E. ciliiyera (Mississippi), E. lenape (New Jersey) and E. pelaena (California). The male of E. inaudita Braun and the female of E. leucosticta Braun are described for the first time. Elachista eleochariella Stainton and E. albidella Nylander (= E. tanyopis Meyrick, syn. n.) are recognized as Holarctic species.

The species of Rhaphium Mg. (s.l.) may be divided, for convenience, into two group—those with white-faced males and those with black-faced males. Since the North American species of the genus were last revised (Curran, 1926, 1927), 13 species belonging to the former group have been described. In this paper one species with black-faced males is described as new, one is recorded from the Nearctic region and one from Canada for the first rime, and one species with white-faced males is also recorded from Canada for the first time.

General Appearance

The family of Nemistrinidæ comprises throughout the world one hundred and ten described species, six or seven of which are from Southern Europe and three from North America; the remainder nearly equally distributed in Asia, Africa, Australia and South America. In their habits, so far as known, the species approach the Bombylidæ most closely, as also do many in their general appearance. Structurally they are of interest to the Dipterologist, on account of their intricate and diverse neuration, which in some species is almost Neuropter-like in the reticulation.Doubtless the number of our species will be augmented by future discoveries, but yet we can never expect a very material increase.

The four North American species of Evernia, E. divaricata (L.) Ach., E. mesomorpha Nyl., E. perfragilis Llano, and E. prunastri (L.) Ach., are discussed from the standpoint of taxonomy, distribution, and ecology. The North American distributions of E. divaricata and E. perfragilis are mapped for the first time. A puzzling lichen found on the ground in alpine areas from New Mexico north to Alberta is regarded as an ecological variant of E. divaricata.

Agalinis Raf. consists approximately of 60 species, 14 of which occur in Brazil. The genus presents predominantly american distribution and the Brazilian species appears mainly in high areas of Minas Gerais. The North-American species are refered as hemiparasites, but there is no anatomical data about it in relation to the Brazilian species. Anatomical studies were conducted to verify whether the Agalinis species from Brazil were root parasites or not. The eight species analysed were presented haustoria which varied in shape, arrangement and size. They were generally elliptic or globose structures and mostly were tightly sticked to other roots in a solitary or clustered manner. The seriate sections of haustoria showed that there was a xylem connection between them and the roots in which they were attached. This fact has confirmed for the first time the occurrence of parasitism in the Brazilian species of Agalinis.
