Arcita proxima. Guérin.—To obtain a feasible knowledge of the extent and direction of variability in this species, extensive material was procured by recrossing original broode and gain their inbred progenies.

There are few things in nature quite so remarkable as the hibernation of insects and animals in a torpid condition. That life should still persist when animationis reduced so low, as must necessarily be the case, with these small creatures in close contact with frozen substances or even imbedded in solid ice, would be quite incredible, were there not so many instances which can be examined by those who wish to do so, every day throughout our long and cold winters.

In “The Canadian Entomologist” for August, 1903 (*), I called attention to the sounds produced by Ranatra fusca, Pal. B. Further study has shown me that the bug I then referred to was in reality Ranatra quadridentata, Stal., and that R. fusca is very rare in the north, if, indeed, it occurs at all, the former being the commonest species in the Eastern United States, the latterm on the other hand, being more southern. The nots referreed to, therefore, apply to R. quadridentata, Stal.

On October 19th, 1904, at Urbana, Illinois, during a week a high south-west gales, I observed a fresh, unrubbed moth at rest on a small tomato that had been placed on a bench in the sun to finish ripening, and in the process had cracked open. The haustellum wad extended down deep into the juicy fruit and the moth gave every apperance to sucking the juice. No Other individuals were noticed abroad at that time.

For over three years we have had in the collection at Ottawa specimens of a pretty little Yponomeutid moth, which we have been unable to get identified.

Larvæ were first observed by the writer at Aylmer, Que., on May 24th, 1901. They were found feeding on stinging nettle (Urtica gracilis, Ait.). and appeared to be fairly abundant in one locality. Specimens collected on this date spun up within two or three days, and the moths emerged on June 7.

Proteopteryx Willingana, Kearf.—Two additional specimens; Regina VII., 20. One strongly marked ♀ and one almost unicolorous ♂, the same as the types.

Ancyclis mediofasciana, Clem.—One specimen; Regina, VI., 18. Does not differ from Eastern examples; already recoreded by Dyar from Kaslo.

In a very interesting collection of mosquitoes lately sent me from the Philippine Islands by Dr. Eugene R. Whitmore, 1st Lt. Asst. Surg. U.S.A., occur a couple of forms which seem entitled to position as new genere, and some others of merely specific interest. The new genera are separated, in the first instance by a combination of values that makes it seem secure, while in the second case it lies between Finlaya and Macleaya, and the differences are not so marked.

During October and November, 1904, I had the pleasure of learning some interesting features of the habits of a certain group of moths which appear at that season of the year. The abundance of these species under seemingly very unfavourable climatic conditions was a great surpise to me. The observations made on these hardy creatures of the insect tribe may prove interesting to Lepidopterists who are willing to exert a bit of energy in the pursuit of their hobby. During the last few years I have learned that we must take the topography of the country into account in selecting a place to bait for the months, which appear after we have observed the first autumn frosts on the landscape.
