THE CANADIAN ENTOMOLOGIST. 87 



What the writer deems the most interesting feature in the life of this 

 species is referred to, but Mr. Edwards's view of the matter seems to be 

 different from his. Speaking of larvse which hibernate after the first or 

 second moult of a brood, part of which reach full growth the first autumn, 

 he says : — " If any of these small larvae run their full course, it seems 

 certain that their butterflies should show themselves at least a month 

 later than the 15th of June, and I do not understand why there is not a 

 second flight." The writer has had the opportunity four times of breed- 

 ing the species from the egg through the first winter, and all of the 

 specimens hatched from eggs laid at Ottawa, Quebec, Banff and Nepigon, 

 went into hibernation after the first or second moult ; one larva, however, 

 of five sent by Mr. Edwards, fed straight on and reached full growth 

 before winter set in. Those which revived the following spring fed 

 slowly and did not attain full growth until the autumn, as related of this 

 species and of Chionobas Macounii in Annual Report Ent. Soc, Ont. , 

 1888, p. 7. 



The third plate, also, figures two rare species of the same genus, 

 which may be included in the Canadian fauna, Crambis, from Labrador, 

 and a mountain species, named Brucei by Mr. Edwards, which has been 

 taken by Mr. Bean, at Banff. The preparatory stages of the latter are 

 beautifully illustrated in great detail, and it is seen that the larva resembles 

 very closely that of C. Semidea. There are some critical notes concerning 

 the synonymy of some allied species, which will be read with interest by 

 students of this difficult genus. 



We feel sure that all entomologists will hail with pleasure the appear- 

 ance of this superb contribution to the knowledge of our Diurnal Lepi- 

 doptera, and we trust that the talented and genial author may be spared 

 for many years to carry on this great work which has cost him so much.

[We were delighted to hear that Mr. Edwards has received a grant 

 of $500 from the Bache Fund of the National Academy of Sciences to 

 assist him in the completion of his publication on the Butterflies of 

 North America. — Ed. Can. Ent.]
