In 1957, some officers of the Forest Insect Survey of Canada discovered a species ofNepticulamining the leaves of white birch (Betula papyriferaMarsh.) and yellow birch (Betula luteaMichx. f.) in Ontario. At that time the species was considered to be undescribed, but to confirm this it was necessary to study the life-history. This has been done by Mr. O. H. Lindquist, Forest Insect Laboratory, Sault Ste. Marie, Ontario, and the results of his studies are being presented in a companion paper. His investigations confirmed that the species had not been named and the following description is presented.

It was with some surprise that the writer encountered a representative of this rare and, until recently, little known genus, from a locality in south-eastern British Columbia. The specimen in question is a female reared at Ottawa, by officers of the Forest Insect Survey of the Division of Entomology, Irom the cocoon of a Chrysopid beaten from Engelmann spruce, Aug. 26, 1938, by Mr. D. N. Ross of the British Columbia Forest Service, in the vicinity of Bayne's Lake, B. C. The adult parasite emerged in the laboratory, Feb. 20, 1939.

During my recent studies on the lepidopterous miners in the needles of various conifers, I have found several undescribed species. One of them occurs near Ottawa, Ontario, and in Nova Scotia. It was also found in Quebec by Dr. J. M. McLeod and Mr. J. A. R. Ducharme, Forest Research Laboratory, Sillery, Quebec. I describe this species here, to enable those officers to report on the immature stages and life history in a companion paper that follows.

Thousands of lepidopterous larvae representing a wide range of species are collected every year in Ontario by the Forest Insect Survey. Many of these require microscopic examination for identification. During a 10-year period I have only found one specimen with an extra pedal appendage.In June 1963, a larva with an extra anal proleg on the right side was collected by H. G. McPhee near Thessalon, Ont., on the north shore of Lake Huron. The species was Epinotia solandriana Linn., a leaf roller on white birch, Betula papyrifera Marsh. A subsequent large collection from the same area contained only normal specimens.

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.

AbstractHypatima mangiferae Sattler sp. n. is described from Kenya, where its larva is injurious to commercial mango trees. A description of its life-history, based on extensive field observations and laboratory studies, is also provided. The moth, its male and female genitalia and the damage caused by the larva are illustrated.

The Bruce spanworrn, Operophtera bruceata (Hulst), is most common in the mid latitudes of the North American Continent; in Canada it occurs from Newfoundland to the interior of British Columbia (Prentice, In Press) and has been reported from Vermont and Wisconsin in the United States (Craighead, 1950.) Three outbreaks of this insect have been recorded in Alberta. The first occurred in 1903 (de Gryse, 1925) and was apparently of short duration. The second reported by Wolley Dod (1913) occurred in 1913 and denuded hundreds of acres of aspen poplar. Heavy defoliation in the third outbreak became evident in 1957 (Brown, 1957) but an examination of Forest Insect Survey records revealed that population buildup began about 1951. The outbreak continued to expand until 1958 and began to decline in 1959; by 1961 populations were again low except for one or two isolated areas where moderate to low populations persisted. At the peak of the outbreak in 1958 approximately 50,000 square miies were moderately or heavily infested and many more lightly infested.

AbstractA new species of Pseudis is described from São Francisco de Paula, Rio Grande do Sul, Brazil. It is known from the southern parts of the Serra Geral where it occurs in grassland, inhabiting permanent ponds and still-water zones of slow flowing creeks. It is characterized by a paired vocal sac and a bulbous thumb, considerably widened at the base. It is distinguished from P. minutus by its different call, body coloration, rounded snout, and a more robust body with shorter hindlimbs. Advertisement call, tadpole, and life history are described. The taxonomy of the family Pseudidae in Rio Grande do Sul is discussed, supporting the synonymy of Lysapsus mantidactylus and P. meridionalis with P. minutus.

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.

The family of winter flies Trichoceridae is newly recorded for Mongolia. Four species, Trichocera (Metatrichocera) gigantea (Dahl), T. (M.) mackenziei (Dahl), T. (Saltrichocera) regelationis (Linnaeus) and T. (Trichocera) hiemalis (De Geer) are first recorded in Mongolia from sampling during 1996, 2003–2006, 2008. A new species, Trichocera (Saltrichocera) chuluuta, is described from specimens collected during the fieldwork of the Mongolian Aquatic Insect Survey Project in western and north-central Mongolia.
