FEMALE. Dimensions of unengorged holotype–1.2 mm. (to tip of scapula) x .78 mm. Colour–pale, dirty white, engorged specimens pale and yellowish.

Capitulum. Length 340 microns (tip of hypostome io dorsal ridge); width (at cornua) 300 microns. Surface of basis capituli smooth and impunctate. Cornua heavily chitinized but not prominent.

It has commonly been observed that grasshoppers readily feed upon dry bran that has never been wetted. From this it was thought that an efficient dry bait might be prepared by spraying concentrated poison solution directly on to an attractive carrier.

Recently I received from Mr. J. Sperry a srnall series of a Thraulodes species from Arizona which, while apparently very closely allied to speciosus Trav. in genitalia, as far as can be told from the rather crude figure (Biol. of Mayflies, 553, fig. 146), does not fit in with Traver's description in several points. I am treating it therefore as undescribed.

The following description is offered in order to provide a name which can be used by economic workers for a species of Argyrotaenia which is destructive to spruce foliage, and which has been erroneously regarded as lutosana Clem., following Robinson's misinterpretation of Clemen's species (Robinson, 1869, Trans. Am. Ent. Soc., II, 279, pl. VI, fig. 59). A subsequent paper dealing with the status of several species in this group is in preparation and more complete notes will then be included.

During a study of the predators of the oriental fruit moth (Grapholitha molesta Busck), the thrips Haplothrips subtilissmus (Hal.) was found destroying the eggs of the moth and also those of European red mite (Paratetranychus pilosus C. & F.).

Thomson, in his review of the Scandinavian Hymenoptera, recognized four genera of Pemphilidine wasps: Rhopalum, Entomognathus, Lindenius and Crabro, the last of which he divided into a dozen subgenera. Two of these, Coelocrabro and Hoplocrabro, were propounded there as new.

The importance of small mammals as natural control factors for forest insect pests has been indicated by several investigators, particularly by Hewitt (8) and Graham (5) with respect to the larch sawfly, Pristiphora erichsoni Htg. and by Sim (9) with respect to the Japanese beetle, Popillia japonica Newm.

Oecanthus pini Beutenmuller. Since O. pini is known to range from Massachusetts west to Ohio and south to North Carolina, it is not surprising to find it in extreme southern Ontario. The specimens here recorded were found on white pine (Pinus strobus L.), red pine (Pinus resinosa Sol. and jack pine (Pinus Banksiana Lam.) in an area devoted to reforestation.

Antepenultimate Instar. Head width 1.4 mm. Body about 13 mm. long and 2 mm. wide. Crochets on first abdominal proleg number 14 to 16.

Penultimate Instar. Head width 1.7 to 2.0 mm. Body from 15 to 17 mm. long and about 2.5 mm. wide; ground colour medium to dark green, the moderately broad white dorsal line separated from the slightly broader white subdorsal lines by twice its width in ground colour; white patches, more conspicuous in anterior segments, immediately distad of each seta alpha; spiracular line dark green, subspiracular line white with a fringe of yellow.

The Strymon species now called falacer Godt., but until recently better known as calanus Hbn. was the subject, in the days of Scudder and Grote, of much controversy. It is not my intention at the present time to enter into the details of this discussion and the names involved; suffice to say that, after a careful study of the literature, I am of the opinion that the present synonym, as given in the 1937 Check List, is correct. The species has been figured on various occasions, but probably the most reliable figure is that given by Austin Clark (Butterflies of the District of Columbia and Vicinity, Pl. XXIV, Fig. 7, 8).

Continued study of the material in the flea collection at the Dominion Entomological Laboratory at Kamloops, B. C., has emphasized certain mistakes in the literature. Some of the more obvious of these are cited in the following notes.

The common blue mud-dauber of the United States and Canada is generally known as either Chalybion caeruleum Linnaeus or Chalybion cyaneum Fabricius (or Klug or Dahlbom). Both names are incorrect. This wasp was first described as Sphex caerulea by Johansson or Linnaeus in 1763 (Amoenitates Academicae, VI, p. 412).

The genus Clistomorpha, as considered by Curran in 1927 (Can. Ent., LIX, 297), contains representatives of a number of distinct genera, namely Clistomorpha Townsend and Hyalomyodes Townsend of the Gymnosomatidae, as well as of Psalidopteryx Townsend and Neopsalidopteryx n. gen. of the Exoristidae.

There is apparently no mention in Canadian literature of the genus Sandalus. No Canadian specimens are present in the collections of the Royal Ontario Museum, Toronto, and there are only two specimens of Sandalus niger Knoch, from London, Ontario, at the Ontario Agricultural College, Guelph. Previous to the writer's donation, there were none in the Canadian National Collection at Ottawa.

Resembling M. prescotia Ball but with vertex margins meeting at distinctly more than a right angle. Length 4 mm.

Vertex flat slightly excavated, almost one-half wider between eyes than length at middle, margins slightly curved out, meeting at distinctly more than a right angle.

For a number of years the fact has been known that colonies of a Coenonympha related to ampelos Edw. inhabit the Mono Basin of California, along the eastern base of the Sierra Nevada. Although the members of these colonies, which are alike, possess characteristics that distinguish them readily from ampelos or any other race of Coenonympha, this fact has somehow escaped the attention of entomologists.

The spring of 1941 in the Ottawa region, being continuously warm and dry, was very favorable for early species of Lepidoptera. Filmata Pears., usually a great rarity, was taken in considerable numbers in a spruce grove, adjacent to a cedar swamp, about 10 miles southwest of Ottawa.

The material used in the preparation of this article included four specimens of the European Scotodes annulatus Esch., two in the Leconte collection and two in my own; three specimens of Anelpistus americanus Horn from the collection of Mr. C. A. Frost, three from the Leconte collection, four from the H. C. Fall collection, fifteen from the general collection at the Museum of Comparative Zoology, and one from my own collection.

Within the past few years, two species of mealybugs have become serious pests of apple in North America. In Virginia, for some apparently unknown reason, the Japanese Comstock mealybug. Pseudococcus comstocki Kuwana, has undergone a change in its feeding habits and produced a strain that has become well adapted to feeding and reproducing on apple.

During the summer of 1941, Colias eurytheme Bdv. appeared in the Edmonton district for the second time in twenty-five years, the last appearance having been in 1923.
