In 1874 Mr. Scudder published his paper on “The Species of the Lepidopterous Genus Pamphila” in the Memoirs of the Boston Society of Natural History, in which the following species were described as new:-Nevada, Colorado and Manitoba, and Sassacus; Ottoe, Juba, Comma of Europe, and Sylvanoides were also treated of.

Aphidius smithi Sharma and Subba Rao is the most important parasite of the pea aphid, Acyrthosiphum pisum (Harris), in North America. In 1958, it was imported into the United States from India to control the pea aphid and was subsequently released and recovered in most of continental United States except the Gulf Coast States and Texas (Halfhill et al. 1972). Mackauer and Finlayson (1967) reported that the parasite was present in Ontario, Quebec, and British Columbia and had been released but not recovered in Nova Scotia. A. smithi has never been released in western Canada nor been found on the Canadian prairies before 1970.

Having recently put my own collection of Dectcidæ into systematic order and treated the collection of the U. S. National Museum entrusted to me by Dr. C. V. Riley in a similar manner, I have thought it would assist n obtaining better material for a future monogroph if I were to publish at least a generic discriminatio of the material at hand. At the same time I am able to clear up most of the synonymy of the species and assign to therir proper location the various described species, very few of which (7 out of 23) will be found to hae been originally placed in the genera to which they are here assigned.

Profenusa lucifex (Ross), a blotch-mining sawfly on oak, Quercus L., is occasionally abundant in Ontario. The adults occur on host trees in June. The larvae, which are described and illustrated, mine the leaves from about mid-June to late July with a small partial second generation in the fall. The insect overwinters in the soil. Three species of chalcid parasites are known to attack eggs and larvae.

As a result of further studies of Eupithecia species chiefly in connection with their genitalia, the following notes have accumulated. As they may be of some certain interest to other workers in the group, I am publishing them at the present time.

Euxoa ustulata n. sp., allied to Euxoa perexcellens (Grote), is described from northern California. Adults and genitalia of both species are illustrated.

Prof. Smith says that he uses the name Xylina in preference to Lithophane, because both are catalogue names and Xylina has priority, since the Verzeichniss was not published until 1818 at least. My argument is, that Ochsenheimer took the name Xylena from Hübner's which is not a Lithophane, but a Hadena.

Since the issue of the Check List of N. A. Coleoptera by the late Mr. G. R. crotch, I have been asked by several persons interested in that branch of science, if I would advise them to change the labels in their collections in accordance with the nomenclature of several familiar genera as therein set forth. To all such applicants I have answered, that such changes are not expedient, unless they are fully, convinced of the propriety of admitting them. For my part, I considered them quite unnecessary, and still further, contrarry to the code of laws of nomenclature under which I supposed we were acting.

While on a short visit in northern Maine during the summer of 1946, I collected a new and interesting ant of the Microgyna group of the genus Formica. The description follows below:

Formica dirksi sp. nov.

Deälate queen, total length 5.1 mm. Head, maximum width through eyes 1.2 mm., at base of mandibles 0.78 mm., length to anterior border of clypeus 1.3 mm. Thorax, Weber's (1938: 155, footnote) measurement 2.1 mm. General characters of the Microgyna group. Mandibles 7-toothed. Clypeus evenly rounded in front, with uneven surface and carina just barely distinguishable as a line anteriorly, but becoming a low blunt ridge through the mid-region and disappearing posteriorly. Head, excluding mandibles and eyes, somewhat longer than broad; narrower in front than in behind, with posterior corners evenly rounded, posterior border and sides slightly convex. Antennae of medium size, scape slightly stouter apically than basally, bent slightly and gradually in basal half, joints 2 and 3 of funiculus distinctly longer than broad; the apical joints only slightly longer than broad. Frontal area distinct, subtriangular, and about twice as broad at base as high. Frontal carinae diverging posteriorly, about as long as width of frontal area. Eyes black, more or less oval, strongly convex, remote from mandibular insertions and close to posterior corners of head. Ocelli medium-sized, round, white and forming an isosceles triangle with a base, which is situated posteriorly, equal to 0.24 mm. Ratio of base to the shorter sides is 10 to 7.

Four new species are described: Mimesa foxi, M. huron, M. iroquois, and M. mallochi. Diagnostic characters are listed for each species and each species is compared with other closely related species in the genus.

Final instar larvae of fall webworms, Hyphantria cunea (Drury), were labelled to equilibrium levels on persimmon leaves containing 45Ca. Loss rates of 45Ca from the larvae were followed in the laboratory after either feeding larvae on unlabelled leaves, or starving other larvae.Initial loss-rate characteristics were different in the two feeding treatments, but biological half-lives were not significantly changed. Feeding shifts the time at which the lower loss-rate comes into effect.

Recently I had the opportunity of watching in a live box, under a low power of the microscope, the seizing and devouring of some plant-lice by the larva of an undetermined species of Chrysopa, and was interested in the manner in which it emptied the body of its victims. The jaws are large, hooked, pointed and tubular, with a small opening at or near the points. Approaching its prey the body of the Aphis is grasped by the hooked mandibles which at the same time pierce it. The Chrysopa larva remains stationary, and proceeds to pump its victim dry. At the base of each of the mandibles the integuments are dilated into a sac-like form capable of expansion and compression at will, a portion of the thorax is similarly constructed, and it is by the repeated dilating and compressing of these sacs that the fluid contents of teh body of the Aphis are transferred through the tubular mandibles to the stomach of the Chrysopa larva.

The species described in this paper are from Mendocino. The genus seems to be more numerously represented on the West than on the East Coast of North America. Some of the new forms resemble the Eutopean. To none of these species can I refer Dr. Boisduval's descriptions of hectoides or californicus.

Larvae of the Australian fossorial carabid Carenum anthracinum Macleay are described from reared material and compared with the reared larva of C. elegans Macleay and eight different unassociated larval types belonging to the complex. These larvae exhibit an extraordinary range of character states indicating clearly that their placement in the tribe Scaritini cannot be retained. An examination of adult characters and, in particular, the fore tibial dentition confirms that Carenum and allied genera form a separate tribe, the Carenini, which appears to be a sister group of the remaining Scaritini (including Clivinina).
