Four species are recognized in the genus Holcopsis Enderlein: bifenestrata (Osten Sacken 1886), fenestrata Enderlein 1923, bequaerti (Philip 1943) and pilifera (Philip 1943). All specimens for which the locality is known are from the State of Durango, Mexico. The genus is characterized and its possible relationship with Bolbodimyia Bigot is indicated. Collection data for all known specimens are given. The species are characterized by the use of a descriptive key. The wing, third antennal segment, and second palpal segment of the female of each species is illustrated.

Two undescribed species of the genus Heptagenia of the maculipennis group are described and illustrated. Heptagenia jewetti n. sp. is known from Oregon, and H. petersi n. sp. from Wyoming and Utah.

Field work in Entomology is full of delightful opportunities, and none, just at present, is more inviting, none more certain to repay well even a little effort, none more sure to yield discoveries of scientific value, than work upon the life-histories of Dragonflies.

Of the species occurring throughout the central tier of States, a majority perhaps has now been bred; but of the Canadian, far western and southern species the known nymphs are few and far between.

The Colorado potato beetle, Leptinotarsa decemlineata (Say), has a genetic system of great diversity and dynamic nature. This results in an enormous adaptability to a range of habitat conditions. Its genetic diversity is exemplified by the existence of color mutants (Tower 1906; Boiteau 1980, 1985).

In the summer of 1986, a red-body mutant male beetle was found in a potato field on the grounds of the Research Station in Fredericton, N.B., Canada. No other red beetles could be found in spite of frequent monitoring of beetle populations. The specimen retains the normal black maculation throughout but all pale yellow to flavous areas of normal beetles have been replaced by the color red (Scarlet 19/3 of the Royal Horticultural Society Colour Charts, 1942). To the best of my knowledge, this is the first report of a red Colorado potato beetle in Canada. Previously, red potato beetles had only been reported from the semi-desertic area of Toluca, near Mexico City (Tower 1906).

This paper contains descriptions entirely of Southern New Mexican forms, with the exception of two from the State of Chihuahua, Mexico.

Twenty-four species of winter stonefly, 8 Taeniopterygidae, and 16 Capniidae, are known from southern Québec; three species, Allocapnia indianae Ricker, A. rickeri Frison, and Taeniopteryx maura (Pictet), are new Québec records. An analysis of the geographical distributions indicates four faunal elements: 6 ubiquitous species occurring over most of the northeastern part of the continent, 4 boreal species, 4 Appalachian species, and 10 species originating from the Mississippi Valley. Except perhaps for Capnia vernalis and C. manitoba, most seem to have survived the glaciations in eastern refugia and have migrated back into Québec along the slopes of the Appalachians. Characteristic species associations can be recognized. In small slow and eutrophic streams of the upper St. Lawrence Valley and the lower Ottawa Valley, Allocapnia granulata and A. vivipara predominate; in the small spring-fed streams of the same area, small populations of A. recta can develop. In highland water courses, a clear zonation is established: headwater streams usually harbour no species; in small streams, capniids, particularly A. illinoensis, Paracapnia angulata and the ubiquitous A. pygmaea, dominate; in larger streams, more capniids are added, such as A. minima, A. pechumani, and P. opis, together with the taeniopterygid T. burksi; in rivers, taeniopterygids abound (T. nivalis, T. parvula, and Oemopteryx glacialis), while the capniids become rarer, A. minima and A. pygmaea. In large lowland rivers, only A. minima and O. glacialis still survive. On the North Shore, boreal elements, such as C. vernalis, Utacapnia labradora, and Taenionema atlanticum, are added or substituted in midsized streams, while in the Eastern Townships, this is true of the Appalachian species A. maria, A. rickeri, and T. maura.

The European pine shoot moth developed successfully on native lodgepole and ponderosa pines at central Oregon locations. Lodgepole and slow-growing ponderosa pine less than 6 ft in height were most susceptible to damage. Largely because of low winter temperatures, interior British Columbia, northern Washington, northeastern Oregon, Idaho, Montana, Wyoming, Nebraska, and the Dakotas are not likely to experience Rhyacionia buoliana (Schiff.) damage. In contrast, southern Oregon and northern California pine stands are highly susceptible.

Ooencyrtus leptoglossi n. sp. is described and illustrated. This species is a parasite of the coreid bug (attacking pine seed) in Georgia, U.S.A.

On a visit to lake Winnibigoshish, Minnesota, on August 26, 1932, my attention was attracted by numbers of this wasp engaged in dragging the mature larvae of the Notodontid moth, Symmerista albifrons S. and A. over the sandy surface of the broad beach. The lake shore is about 300 feet wide at that place and composed of several distinct levels. The lower areas nearest the water are covered with low growths of willow and poplar, among which the wasps seemed to prefer to bury the paralysed caterpillars. The latter had developed on the oaks in the forest bordering the lake and several were seen crawling on the sand below the trees, presumably seeking places for pupation. The wasps doubtlessly seized their victims on the ground.

Craighead (1923) described the larvae of four North American species of Acunthocinus and constructed a key for their separation; two of these, A. nodosus (Fab.) and A. obsoletus (Oliv.), occur in the eastern half of the continent. During recent studies of cerambycids infesting fire-killed pine in central Ontario, another species, A. pusillus Kby., was encountered in large numbers, but the larvae could not be identified because of the lack of a published larval description. Larvae were eventually reared from known parent adults, and, since wood-boring Coleoptera are most frequently encountered in immature stages, the following description has been prepared.

In a 1984 study on the ecological factors influencing the forest vegetation in the southern region of the province of Quebec (Gauthier 1985; St-Jacques 1986), an adult specimen of Cleruchus biciliatus (Ferrière) was found. This is the first record of the occurrence of the species in North America.

Sampling was done in 120 sites selected in a stratified random design in natural forests of the Mirabel area, northwest of Montreal (from 45°33' to 45°45'N and from 74°3' to 74°44'W). At each site, vegetation was sampled from an area 20 by 50 m. A 400-cm2 sample of litter was taken from each of these areas. In the laboratory, the litter samples were put into modified Berless funnels (Phillipson 1971). Following a 48-h extraction process, the organisms, collected in 70% ethyl alcohol, were identified and counted.

I have indicated in this short paper where the types of my Geometrid species are to be found, to the best of my knowledge, and I have given such additional information as I am possessed of with regard to the species. I have followed the classification of Dr. Packard, except in a few instances where I have found reasons to prefer other names. I refer to my paper, Can. Ent., 8, 152, for a review of the synonymy of certain species. Two species, one described by Dr. Harvey (viz., Endropia Warneri), have been re-named by Dr. Packard, who calls Dr. Harvey's species Apiciaria. As to whether we must put the terminations aria and ata (accordingly as the ♂ antennæ are pectinate or not) I cannot attempt to decide. I think it is advisable to bear this rule in mind when naming species, but I would not change therefore any names already in use. Especially do I think it unadvisable to place the termination after a proper name. I should call the Endropia, E. Warneri, not E. Warneraria.

In July, 1956, a pupa of the imported cabbageworm, Pieris rapae (L.), was found attached to the undersurface of a corn leaf in experimental plots at St. Jean. After the pupa had been incubated at 75°F. for six months, a dipterous parasitic larva emerged and pupated immediately; a tachinid fly emerged two weeks later. The parasite was identified by Mr. J. G. T. Chillcott, Entomology Division, Ottawa, as Phryxe vulgaris (Fall.). P. vulgaris has been reported as a parasite of Pieris rapae, P. brassicae (L.), P. napi (L.), and Vanessa urticae (L.) from many central and northern European countries (Thompson, 1946, pp. 467-469; 1947, p. 598). Aldrich and Webber (1924), Chittenden (1926), and Schaffner and Griswold (1934) reported this parasite from P. rapae in the United States. P. vulgaris has been reported from Canada only on larvae of the armyworm, Pseudaletia unipuncta (Haw.), in Nova Scotia and New Brunswick (Gibson, 1915, p. 14).
