Our Canadian wood-boring beetles, with the exception of a few somewhat minute species, belong to the two great families of Buprestidæ and Cerambycidæ. These include an immense number of different genera and species ; in Crotch's List of the Coleoptera of North America (north of Mexico) there are enumerated the names of no less than 169 species of the former family and 552 of the latter ; about one-third of these are found in this country. It is evident, then, that to give a bare list of all our Canadian species of wood-borers would occupy no 1ittle space, while a detailed description of them, if one were competent for the task, would fill many numbers of this journal.

In the early spring, from the middle to the end of April, Prof. Lintner and Mr. Hill have taken near Albany a rather small and inconspicuously colored moth, remarkable for its diurnal activity. At first sight I did not recognize it as belonging to the Tortricidæ, but on examination it shows the family characters and seems to be allied to the European genus Cheimatophila. But it is not vein 4, but vein 5 that is wanting on the hind wings, and the other characters sufficiently separate our species.

For the purpose of further testing conclusions stated on p. 174 regarding Homopteras lunata, edusa and Saundersii, I have secured all observed at my sugar since the former writing.

There are 38 “lunata,” 23 “Saundersii” and 18 “edusa.” Having opportunity to examine these while fresh, I observed the anatomy of the sex organs in each specimen as captured. The result verified the view previously advanced–the lunatæ were all females, the Saundersii and edusæ all males.

Egg laid July 16th, on grass, the female being confined in a bag over a tuft of grass set in a flower pot. Shape nearly that of a semi-ovoid, the base being flattened and the sides at base rounded, the surface under a low power smooth, but under a higher seen to be covered with shallow thimble-like depressions : color greenish-white.

Hatched July 20th.

Young larva–Length 0.09 inch.

My observations on both of these species scarcely permit me to doubt that their larvæ feed in some way on the Honey Locust (Gleditschia tricanthos), though neither of them has been bred from the larva. I have, however, met with a larva from which I have not succeeded in breeding the imago, and which I believe to be the larva of one of these species. It is a Gelechia-like, about half an inch long, with sixteen feet, and feeds inside the seed-pods of the Gleditschia, on the honey-like substance found in them, and not, so far as I have observed, on the seed.

I have received from Canada (London, Mr. Saunders) a nerv and easily recognizable species of Nola,larger than ovilla, and in describing it, I have again gone over the characters of Argyrophyes, which I find to be allied to Nola, and not to belong to the Geometridæ. I have corrected my former observations on Argyrophyes, which I find to have been largely erroneous.
