Having prepared a case of insects for a Toronto Public School teacher, for her class-room, I thought it might be a stimulus to others to do likewise, if the details were given some publicity.

All of us wiht medium-sized or large collections have duplicates enough from which to select material for such a case without impoverishing our collections, and now that so many public schools have departments of manual training there should be no difficulty in getting the teachers in these departments to co-operate by supplying the necessary cases.

Halictus hortensis, n. sp. ♀.—Length, 5 mm. Head and thorax green, abdomen black, with the apical margins of the segments brown. Head nearly as broad as long, face finely and densely punctured, thinly clothed with a short white pubescence; mandibles bidentate, rufous at tips; antennæ black, pubescent, flagellum with minute appressed hairs, brownish beneath. Mesothorax nearly bare, finely and sparsely punctured; disc of metathorax rounded or somewhat traingular, evenly and finely rugulose or roughened.

I am very much indebted to Mr. T.N. Willing, a Regina, Assa., for the privilege of working up a very interesting collection of Micro-Lepidoptera. It is particularly notable in recording a number of species that have hitherto been only known by the types, and especially so in establishing a wide range of territory to species that have been only recorded from California. Following this paper I have one in preparation on the same subject, from material collected in Manitoba by Messrs.

219. N. havilœm Grt. — I confused this with the foregoing species until quite recently, so cannot state positively whether it is common or not. From memory I should say at least not rare. I picked four out of my series of twenty-five clandestina and sent two to Prof. Smith as possibly havilœ, but questioned their distinctness. He called them havilœ, and added, “The differences seem obvious enough in my Collection. It has the ground colour of primaries lighte, has a peculiar strigate appearance, and lacks all the red-brown that occurs in clandestina.”

On September 4th I found, feeding on leaves of Nasturtium, two larvæ which I had never seen before, and which agree exactly with figures and descriptions of the larvæ of the “Large White Butterfly” of Europe, Pieris brassicœ

Dr. Harrison G. Dyar, in the Proceedings of the Entomological Society of Washington, VI., No. 4 has given us a very interesting and important paper on the Hulst collection of Geometridœ.

In this paper he has shown, from an examination of the type specimens, that a considerable number of Dr. Hulst's supposed species are not really entitled to specific rank. Of course, any entomologist describing as freely as Dr. Hulst did would be sure to make some mistakes and create some synonyms, and I have no doubt that Dr. Dyar is prefectly correct in his judgment in the majority of cases that he cites.

In Schletterer's “Die Hymenopteren Gruppe der Evaniiden,” Annalen d. k. k. Nath.Hofmuseum Wien, IV., p. 311, read trochanterata, Cameron, for trochanterica, Cameron. Page 338, the locality for Evania semirubra, Cresson, should be Cuba. Page 118, in synonmy of Evania, date 1829, after “Evania, Curtis,” should come the following reference: “Brachygaster, Stephens Systematic Catalogue of British Insects.

Head of moderate size, not retracted; eyes round, hardly prominent, yet distinct and of good size; front protuberant inferiorly, with a roughened depression guarded by a sharp rim; palpi small, slender, not attaining the end of the protuberance; tongue weak, yet of moderate length and perhaps, functional; antenna in the male with the joints a little marked, ciliate rather than bristle tufted. Thorax oval, convex, collar and patagia distinct but not uplifted; vestiture scaly; no tufs; legs moderate, on normal proporations, without spines, spurs or other armature save the usual spurs of tibiæ.
