Coleocentrus canadensis, n. sp.

Female.—Length, 20 mm. Black, with red legs. Head transverse, as wide as thorax; cheeks as wide as eyes; face slightly swollen below antennæ, clothed with short pubescence, and with the inner orbits faintly yellowish below; palpi and inner edges of mandibles and labrum rufous; vertex and cheeks polished, the area of the ocelli without noticeable depressions or sutures; antennæ long and moderately thick, the joints about forty and subsequal. Thorax polished above; the lobes of the mesothorax prominent, the central sulcate; pleuræ and pectus rugose or subaciculate, but without definite striæ; scutellum moderately large and elevated; metathorax with acute carinæ; the area enclosed by the two discal carinæ about twice as long as wide; in the area enclosed by the two lateral carinæ the elongate spiracle may be plainly seen almost in centre; the areas between lateral and discal carinæ transversely rugose; legs slender with robust coxæ, entirely rufous with exception of hinder tibiæ and tarsi, which are somewhat brownish; wings faintly yellowish, stigma and nervures brown, areolet small, triangular and pedicellate, receiving the recurrent nervue at outer angle.

Blacodes cristatus, n. sp.,♀

Wholly black, the tibiæ slightly piceous. Head light gray pollinose, that in middle of the front dark brown; face moderately convex, mystax black and white, very dense and extending nearly to the antennæ first joint of antennæ slightly longer than the second; third joint lanceolate, three times as long as the second joint; style slender, slightly over half as long as the third joint. Thorax very convex, gray pollinose and marked with a broad blackish-brown geminate median stripe, which is considerably dilated outwardly behind the middle; on each side of this stirpe is a broad, irregular, blackish-brown stripe extending but little in front of the middle of the dorsum; the median brown stripe bears numerous black and light yellow pile, which, on the anterior portion, forms a nearly erect crest; bristles of thorax black and light yellow; pleura mottled light gray and dark brown pollinose, the pile white; the fan-like row of bristles in front of the halteres is white.

The following fragmentary contributions to a knowledge of a few of the destructive insects of this most interesting State are given here, not so much on account of their present individual value, as for the purpose of drawing attention to the riches in store for the entomological worker who may drift within its borders. In new countries travellers, in passing through, blaze or bark a tree here and there along the way to guide those who may follow after. These notes may be but blazes, but if they prove of aid to others in the future, they will have served their mission.

As has been shown by Mr. R. H. Stretch, the North American species of Clisiocampa are best separated by larval characters, and this paper will deal chiefly with them. I refer to Mr. Stretch's paper in volume 1. of Papilio, which contains about all that has been known reagrding the species.

In reply to Mr. Charles A. Hart, who has shown, in the last number of this journal, that in his opinion I am in error regarding the identification of Astatus bicolor, Say, I would say that the stigma of the ♂ only is “yellowish-rufous”, while that of the ♀ varies from reddish-black to deep black. If he will again consult my synopsis of the genus Astatus he will find that I used the words “stigma of wings black” in separating those of the female sex. In regard to my new species, A. pygidialis, which Mr. Hart suggests may be an exteme variety of bicolor, it differs not only in the slight characters mentioned by him, but also in the shorter and triangular pygidium, and the more feeble armature of the legs; the scutellum is not furrowed down the middle, and the insect itself is much smaller.

The “Revision of the Genus Cucllia,” by Prof. Smith, in Proc. U.S. Nat. Mus., XV., pp. 33.et.seq., raises the number of described North American species sto 14, and is an interesting addition to the knowledge of our Noctuidœ. Larger collections from the west have come to hand since my study of the species and have admitted of fuller comparisons. Although the species of Cucullia are not among the commonest Owlet Moths and seem to fall less easily a prey to the collector's efforts than those of many other genera, still we may conclude that the above figures give, at least approximately, the N.American representation of the genus.

A round, white, woolly gall was found on stems of Bigelovia (sp. probably graveolens)in several localities in western New Mexico the past summer, from June 19 to 22. Those found June 19 were old galls, and were met with near Luera Spring, in Socorro county. On June 21 the fresh galls were found in numbers near Gallo Spring. Sometimes two or three were found near each other on the same stem or twig of the plant, and in one case three galls were found joined together, forming a triple gall. On June 22 they were found extremely common west of Apache Spring, thus seeming to increase in number in a westerly direction, as did also the patches of Bigelovia, every plant of which was full of them.

The material forming the basis of this paper was sent to me last October by Prof. C. V. Riley for determination. The species were collected by H.H. Smith in St. Vincent, West Indies, and are among the most interesting forms of this remarkable family.

In that most useful paper, the “Directions for Collecting and Preserving Insects,” by Dr. C. V. Riley, Washington, 1892, occurs the statement, on page 137, that the periodical, the North American Entomologist, was “published by the Buffalo Society of Natural Sciences.” The fact is that the little monthly, which only reached its first volume, was edited by myself, and printed and published by Reinecke & Zeschm a Buffalo printing house. The material was written or collected together by myself, and the few plates, mostly contributed by the authors, were gotten up at my sole trouble, and even expense.
