During the course of investigations of the life history of the pine root collar weevil, Hylobius radicis Buchanan, in Wisconsin, a larval parasite was encountered by the junior author. The Braconid adults which emerged represent an undescribed species of the genus Bracon.

Material collected in Loch Tannoch was allowed to macerate in a chemical nutrient. A rich crop of Euglena gracilis as well as other infusoria resulted. Eight months later, when the Euglena had encysted, many amoebae were found at the bottom of the receptacle. They constitute a new species, here named Amoeba hugonis. An average adult specimen, when extended, measures about 104x52·2µ. The nucleus consists of a central karyosome lying in the nuclear sap, separated from the cytoplasm by a wellmarked nuclear membrane. Between the latter and the karyosome is situated an achromatic ‘collar’ with chromatin particles embedded in it. Fission is described, but a study of mitosis has been deferred. The life-history of this small amoeba is very similar to that of the large A. proteus, &c. The cycle occupies two months. Chromidia begin to appear in the cytoplasm of the early adult. They give rise to spores, out of which amoebulae hatch.

A New Species

A half a century ago, R. T. Leiper described a new species belonging to the genus Fasciola from specimens which he collected from hippopotami at the Murchison Falls, on the Victoria Nile in Uganda, in the summer of 1907. This species, Fasciola nyanzae, was found in the bile ducts of the liver, and in most instances the specimens were somewhat macerated owing to the length of time that had elapsed before the animal could be recovered from the water. Nevertheless, the characteristic shape of these liver flukes and the restriction of the branched testes to the anterior third of the body made it possible to recognise them as being different from all other species of the genus known at that time.

Definite Proof

During a visit to Professor Fernald, in Amherst, Mass., last spring, he showed me a Nepticula, bred from Apple, which he had described in manuscript as a new species, but which he afterwards had suspected to be Micropteryx pomivorella, Packard.From reading the description and life-history of packard's species, I felt sure that it was a Nepticula and presumably the same as Professor Fernald's species, and a week after, while studying the collection in the Agassiz Museum, Cambridge, I obtained definite proof that we were right.

The larval morphology and life history of the weevil parasitoid Eutrichosoma mirabile Ashmead (Hymenoptera, Chalcidoidea, Pteromalidae) are described, and the phylogenetic placement of the subfamily Eutrichosomatinae within Chalcidoidea is determined using larval morphological characters. A description of Eutrichosoma burskisp. nov. and key to the species of Eutrichosoma are provided.

A new species of Neocarus is described from adult female and male specimens collected from an epigean and hypogean ferruginous geosystem located in southeast Brazil. The new species, Neocarus simmonsisp. nov., possesses 15–17 ch-type palp setae, nude female pregenital Sternitogenital region, cylindrical ovipositor without setae, and a peculiar variation of setae in the genital and pregenital Sternitogenital region of the male, with smooth and tapering setae and/or barbed and tapering setae and/or stout and ribbed setae. Female genital setae are barbed, tapering and with a thin tip. Aspects of the ecology and life history of these mites are also presented.

A New Species

Ecuador has the biggest number of amphibian species per unit of area in the world (425 species in 276,840 km2). In the last decade, conservative estimates indicate that at least 26 species of Ecuadorian amphibians have declined or gone extinct. The reasons for this crisis are not clear but have been related to habitat destruction, climate change, and/or fungal disease such as the chytridiomycosis. The Río Palenque Science Center (RPSC) was among the last remnants of tropical rainforest in the western lowlands of Ecuador. Twenty years ago, investigations done by R. McDiarmid and others lead to the discovery of an amazing herpetofauna, including several undescribed species. However, the expansion of the agricultural frontier and transformation of the forest remnants into oil palm and banana plantations destroyed this site. Among the species identified from RPSC were five species of glass frogs (Family Centrolenidae): Centrolene prosoblepon, Cochranella spinosai, Hyalinobatrachium fleischmanni, Hyalinobatrachium valerioi, and an undescribed species of the genus Centrolene restricted to the RPSC. This research analyzed the morphological characters and natural history of the five glass frogs of RPSC in order to describe the new species of Centrolene from RPSC, which is critically endangered, if not extinct. The new species is characterized by combination of the following characters: 1) a distinctive coloration with yellow dorsolateral stripes; 2) the presence of an exposed prepollical spine; 3) a humeral spine in the males; and, 4) a unique nuptial pad between the fingers II and I.
