Since I came to this island, a couple of seasons ago, I have made a practice of capturing any insects that came in my way, and I have sometimes made an expedition purposely in pursuit of such prey. The result is an accumulation of about one thousand species of all orders, which probably represents not more than five per cent. of our insect population.

As my favorite studies are in another department of Zoology, I have neither the inclination nor sufficient knowledge to work out all this material myself, but with the help of entomologicai friends, resident, alas! sadly, too far off, I am gradually making progress with the naming of my captures, and I propose, with your permission, to publish from time to time in the Canadian Entomologist, lists, with notes, of the species that have occurred to me. I hope that this will be both useful and interesting to Eastern entomologists, as I notice that hardly more than one half of the insects I have already identified are named in the recently published check list of Messrs. Brodie & White, and many of them will prove, I think, new to science.

At the time when my Catalogue of the Tortricidæ was published, I was inclined to believe that Cacœia transiturana Walk., and C. obsoletana Walk., were the same species, for they were taken in the same localities, and only females of the former and males of the latter species were to be found in collections.

Prof. Forbes has recently sent me two examples for determination, which he bred from two lots of leaf-rollers on the strawberry, in Illinois, and from each lot he obtained males and females, all the males being obsoletana, and all the females transiturana. We may, therefore, consider the question settled by Prof. Forbes, and these two insects are only the two sexes of our species, which should be known as Cacœcia obsoletana Walk.

Pupal Term of Arctia nais.

♀ found June 16, 1875, laying eggs in a depression in ground recently dug. Total number of eggs obtained about 500, 16th to 19th of June.

Larvæ began to appear June 24th. They were fed chiefly on Polygonum acre, and one or two species nearest allied to acre, partly on Polygonum aviculare, var. erectum, and partly on red clover.

Pupation began July 23rd, and continued daily to August 8th, inclusive; a few more pupæ formed to the 16th inclusive, when pupation practically ceased, Only 5 pupations occurred later; two about 20th of August, one about 1st of October, and two in the last ten days of October.

Egg laid on the under side of the reaf of the Dock (Rumex obtusifolius). Newly hatched larva bites through to the upper surface of the parenchyma, and works under the epidermis, until the leaf presents a blistered appearance. sometimes three or four larvæ are found in one leaf.

Full-grown larva, four-tenths of an inch long, white, semi-transparent. Segments marked with greenish yellow. Head retractile, furnished with a snout-like process, the apparent use of which is to raise the epidermis as the creature feeds. Mouth set back. Alimentary canal visible under the microscope, also two ducts terminating in spout-like organs protruding from what appears to be the upper edge of the somewhat truncated last segment of the larva. The tuberculose spiracles on the second segment very conspicuous; on the third, less so, and so on diminishing.

The ultimate extinction of many species of Coleoptera in the vicinity of large cities is unquestionable, especially of the larger Carabidæ. The conditions of life with some are such as admit of no adaptation to the methods of civilization, and for them no refuge from the encroachments of agriculture will eventually remain. They are now retiring, retiring, and in time the last goal will be reached. In localities where the population is becoming dense, and all land available placed under cultivation, many fine species that once were common are now rarities and others fast becoming so. It is less than half a century since Mr. Randall described eighty four species from localities in Maine and Massachusetts, most of them common; but, according to Mr. Austin, in the same places several of these species are now extinct and many of them have become rare.

A11 the insects mentioned in the following notes were captured by myself during the season of 1882, which was my first year in this island, and were taken for the most part on flowers in the course of my rambles. Some of the Ichneumons, however, were bred from the pupæ of Lepidoptera, and a few species were taken at rest, at light, or in other more or less usual ways.

The eighty species here enumerated have been examined and determined for me by Mr. W. Brodie, of Toronto (to whom I am much indebted for this and other kindnesses), and they are therefore nearly all of them included in the check list issued last year by the Natural History Society of Toronto. In fact, the only names that I do not find in that list are Halictus lœvipennis and Eurra albitarsis, but they may perhaps be there under other names which in my ignorance of synonymy I fail to recognise.
