Head, legs, antennae and ground color of wings ochreous tan in male, straw color in female. Front and palpi in both sexes reddish. The fore wings subfalcate in the male, falcate in the female. T. a. line very faint, narrow, often obsolete at costa, starts one-fifth out from the base on the costa, runs outwardly oblique to the cell, thence curving usually evenly, sometimes slightly wavy sub-parallel to the outer margin, reaching inner margin about one-fifth out.

The western tussock moth, Orgyia vetusta Boisduval (Lepidoptera: Lymantriidae), formerly known as Hemerocampa vetusta (Boisduval), occurs primarily in coastal areas of central California and south into Mexico, with occasional records east of the central Sacramento and San Joaquin valleys (Ferguson 1978). Two biotypes, feeding on perennial yellow bush lupine, Lupinus arboreus Sims (Fabaceae), or silver dune lupine, Lupinus chamissonis Eschsch. (this study), and on California live oak, Quercus agrifolia Née (Fagaceae), respectively, have been recognized and were originally considered two separate species (Edwards 1881; Ferguson 1978). Various fruit and nut trees have also been reported as host plants (Atkins 1958)

We tested the pyrethroid insecticide esfenvalerate in single, double, and triple applications for control of insects affecting seed production of blister rust-resistant western white pine, Pinus monticola Douglas. All treatments increased the proportion of normal seed produced and reduced the proportion of seed damaged by the western conifer seed bug, Leptoglossus occidentalis Heidemann. Only the triple application reduced the proportion of cones killed by the pine cone beetle, Conophthorus ponderosae Hopkins. Other seed-damaging insect species [seed chalcids, Megastigmus sp.; the fir coneworm, Dioryctria abietivorella (Grote); and seedworms, Cydia sp.] were present but in numbers too low to test for insecticide efficacy.

Hadena perpenoa, n. s.

♂. Eyes naked ; tibiæ unarmed ; abdomen tufted ; size moderate. Apparently allied to Indirecta and Cinefacta, but darker colored, with a certain resemblance to Mamestra Atlantica or Vicina. Concolorous dark wood brown ; lines faint. The usual markings. A dash connects the claviform with the t. p. line.

There are few things in nature quite so remarkable as the hibernation of insects and animals in a torpid condition. That life should still persist when animationis reduced so low, as must necessarily be the case, with these small creatures in close contact with frozen substances or even imbedded in solid ice, would be quite incredible, were there not so many instances which can be examined by those who wish to do so, every day throughout our long and cold winters.

Upon request, I sent to Dr. H. A. Hagen specimens of the parasite of the Phylloxera, Diplosis (?) grassator. At the same time I sent him specimens of the Psylla described on page 198 of vol. xiv. Dr. Hagen favored me with information as follows:—

“The fly is a Cecidomyia; I think it is not sure that it belongs to Diplosis. At least the reticulation of the wing differs in having the median vein straight, and the fork at the hind margin wanting. You will see in Osten Sacken's Catalogue that the museums do not possess this type for Cecidomyia. I have gone through the literature, and find till now your species is not described. The larva is shrivelled up, therefore the trophi are not visible.

Lectotypes are designated for Margaronia curvilinea Janse, 1924, and Margaronia pratti Janse, 1924. These species are referred to Palpita Hübner, [1808], as new combinations. They are redescribed and differentiated from certain closely related species. Phalaena Geometra annulata Fabricius, 1794, and Botys partialis Lederer, 1863, are treated as species inquirenda in the absence of type material. Glyphodes celsalis Walker, 1859, and Margaronia inusitata Butler, 1879, are treated as distinct species and are transferred to Palpita as new combinations. Margaronia warrenalis Swinhoe, 1894, is transferred to Palpita as a new combination; a lectotype is designated for this species and its characters are compared with those of P. curvilinea. Palpita varii n. sp., from Manusela, Ceram, and P. jansei n. sp., from the Island of Mioswar, Geelvink Bay, New Guinea, are described from holotypes drawn from the type-series of P. pratti; characters differentiating these three species are given.

Larvae of the black spruce cone maggot, Strobilomyia appalachensis, were infected and killed by Steinernema carpocapsae (Weiser) All and Umeå strains, S. feltiae (Filipjev) (= bibionis) strain 27, and S. glaseri Steiner strain 326, in laboratory tests. After formation of puparia, however, cone maggots were practically resistant to all species and strains tested. Very few or no maggots were infected when nematodes were sprayed on or injected into infested spruce cones. The survival, activity, and infectivity of infective juveniles held in an aerated infusion of black spruce cones were significantly lower compared with those held in aerated water. In peat–sand columns, the proportion of larvae infected with S. feltiae, but not S. carpocapsae Umeå strain, was significantly greater when larvae were dropped immediately or 1 day following nematode application compared with 1 day before or 3 days following nematode application. Our results suggest that, in field trials for cone maggot suppression, nematodes should be applied within a day prior to larval drop and that repeated applications may be required for persistence of sufficient infectivity.

During the latter part of August and early in September, 1950, dolichopodid flies were observed feeding on adults of the European red mite on apple foliage, untreated with acaricides, in the Science Service orchard, Harrow, Ontario.

Specimens were determined by Mr. J. R. Vockeroth, Systematic Entomology, Division of Entomology, Ottawa, as follows: Condylostylus sipho (Say), Laxina nigrofemoratus (Wlk.), and Diaphorus or Chrysotus sp.

Certain of the nesting habits of the wasp, Sphex xanthopterus (Cam.), have been observed at and near Los Angeles, California. The insect nests for the most part in the moist or wet, sandy soil of the river bed. It digs a short tunnel and enlarges it into a cell at the end. Into this is stored a stung lepidopterous larva, often the young of the moth, Zale lunata (Drury) and its varieties, to the side of which is fastened the egg of the wasp. The entrance to the tunnel and nest is then closed and in due time, if all goes well the egg hatches, the larva devours the prey, spins its cocoon, pupates, and later emerges an adult wasp. A more detailed account of some of the facts in its nesting habits and life history is given below.

20. Schistocerca americana, Drury.

Gryllus americanus, Drury, Illustr. Nat. Hist., app. (1773).

Acridium americanum, Scudd. Mat. Mon. N. A. Orth., 466 (1862).

Schistocerca americana, Blatchley. Can. Ent., XXIII., 79 (1891).

This large and beautiful locust has been twice reported from Ontario, at London, (Can. Ent., XXVII., p. 52), and at Toronto(Can. Ent., XXIX., p. 89), a single example being taken in each instance. These were probably wanderers from the South, certainly in the case of the Toronto specimen, and the insect can hardly be regarded as a native of our Province, though it may be established in the extreme southern portion.

The following bees, obtained by Professor Brittain of Macdonald College, are of more than ordinary interest and should be recorded.

A undescribed variety of Cicindela vulagaris, Say, is reported from the basin of the Rogue River, in S.-W. Oregon. Twenty specimens taken during the month of April of this year, and closely representative of the local tribe, present no differences except a slight one in shade of colour, indicating, apparently, that the variety is well established and worthy of a descriptive name. The elytra markings are identical with those generally recognized as possessed by vulgaris proper. It is slightly narrower and the upper surface more convex than the type. The colour is a dull coppery green, the metallic hue being more apparent, as is usual in other species, at the edges of the elytra. It seems to be a connecting link between the type and variety vibex, Horn. Its habitat suggests the name C. roguensis.

An excellent way to present generic revision is to show the names arranged in annotated check list style. This method stresses classificational position. I believe entomologists in general are becoming more concept-minded and realize the need of improved lower categorical systems and better Code Rules governing the arrangement of their names. In lepidoptera this need is felt strongest. (See note under No. (15) in this article and also the Entomological News for July, Nov. and Dec., 1932, for further discussion.)

Resembling T. gillettei but somewhat larger. Two inner pairs of processes of aedeagus of about same length with innner pair not bent at middle and dorsal spine as long as shaft is wide. Length 4.5 mm.

Color: As in heavily marked T. gillettei V. D.

The greta interest in which this beetle has been held by Entomologists for so long has renderes an accurate account of its habits very desirable ; but for a very long period–over twenty years–it has singularly eluded more experienced observers. In the Proceedings of the Kansas Academy of Science for 1876, a slight account was published by Mr. H.A. Brous, but from the very small number taken by him, his article was necessarily imperfect.
