In the Report of the Entomologist and Botanist to the Dominion Experimental Farms for 1905, at pages 179 and 180, considerable space is given to a discussion of an outbreak of a large noctuid caterpillar, which appeared in considerable numbers in Canada during 1905. Complaints of injury by this insect were received from a wide area, extending from Nova Scotia as far west as Lake Superior. During July many kinds of plants in gardens were attacked by smooth cutworm-like caterpillas, which when small were greenish in colour, having the body divided into two equal areas above and below the spiracles by a wide black stigmatal band.

In the revision of my Manual of North American Diptera, now in press, it has been necessary for me to examine ciritically the recent publications on the classification of the Culicidæ. Although I have never ceased to be an interested reader of dipterological literature, I was hardly prepared for the flood that has nearly swampted me in the attempt to reach terra firma.

The species described below were all included in a paper on B.C. Geometridæ, which was read by title before the Royal Society of Cananda last May.

Unfortunaterly, it was not possible (owing to pressure of other work) for me to complete the paper in time for publication in this year's volume of the Transactions, and as the names have all appeared in a “Check List of the Lepidoptera of British Columbia,” recently published by the Provincial Department of Agriculture, it seems better to print the descriptions now in the Canadian Entomologist than to wait the appearance of next year's volume of the Royal Society's Transactions.

These notes refer to a small but interesting collection of Hemiptera taken about Lake Temagami in August, 1906, by my friend, Mr. William J. Palmer, of Buffalo. Before starting for a brief vacation trip to northern Ontario, Mr. Palmer very kindly offered to collect Hemiptera for me as time and circumstances would permit. On four days only was he able to do any collecting, but considering the unfavourable conditions, the results were remarkably good, both as to the amount and character of the material brought home.

On the morning of November 8th I was fortunate enough to watch the pupation of a caterpillar of Euvanessa antiopa, L. The operation has often been described, but it seems worth while putting another observation on record, which was carefully watched by Mr. Arthur Gibson and myself, from the time the larval skin first burst unitl the cremaster wad firmly fixed in the silk. The chrysalis first appeared through the black skin as a white dash in the middle of the second thoracic segment.

Recently a medical friend, Dr. A.E, Ayler, called my attention to some “worms” which he had found under pecuilar conditions.

A patient, an elderly lady of one of the best families, was suffering from a malignant tumor—a melanotic sarcoma—located in the small of the back. The tumor was about the size of a large walnut. On examination the doctor was surprised to find, close to the stalk and between the tumor and the body, some ten or tweleve “worms” which were feeding upon the diseased tissues.

The genus Trichodezia, Warren, established in 1895 (Nov. Zool. II, Part 2, page 119), will now contain two of our species. In a former paper (Can. Ent., Vol. 38, p. 38) I stated that Euchœca albovittata, Guen., should, as Mr. Warren placed it, be recognized as the type of this genus, and ventured to predict that Euchœca Californiata, Pack., would go with it. Since then, through the kindness of Mr. Beütenmuller, of the Amer. Museum of Nat. History, N.Y., I have received a male of this species, and find the peculiar generic characters present.
