THE CANADIAN ENTOMOLOGIST. 



able from examples of Hecla from the Arctic Sea, except that the Meadii 

 males (as well as Elis) have the mealy spot on costal margui of hind- 

 wings, which Hecla shows nothing of. If a Hecla ever appeared with 

 that spot, I should say the two were forms of one species. 



I sent a pair of these to London to be submitted to two of the most 

 experienced lepidopterists there, and asked them to tell me in writing 

 what the species was. I gave no information about the pair, except that 

 they were taken somewhere in America. Both the experts replied that 

 the species was Hecla, but they noticed the presence of the mealy spot. 

 In the museum collection, all the male Hecla were without that spot, and 

 I cannot learn that it is known in any collection. 



These pale examples are not worn but are fresh and evidently not 

 long out of pupa. They must be the product of eggs laid by the earlier 

 imagos the same season. Mr. Bruce wrote 7th Sept., 1890, that he had 

 "just been up Gibson Mountain; elevation 14,000 feet; all barren and 

 desolate. All I saw was two Alexandra and three Scudderii, half a 

 dozen Meadii, a dozen Arg. Eurynoine, and as many P. Smintheus. I 

 send two of the Meadii to show you the colour." These were the first 

 examples I had seen approaching Hecla, and on calling Mr. Bruce's 

 attention to them, he presently took several others of same type about 

 Hall Valley. That the imagos do sometimes come out the same season 

 the eggs are laid, appears from my experience with larvae at Coalburgh. 

 On 23rd July, 1888, I received larvae just out of egg from Mr Bruce ; 

 these passed the first moult, 27th ; one jiassed the third moult 9th Aug.; 

 the fourth, 14th; pupated, 19th ; and the imago came out 25th August. 

 The rest of the larvae passed the third moult and hibernated. I sent 

 them to Clifton Springs, N.Y.; got the survivors back in April following, 

 and on 21st and 23rd April they passed the fourth moult ; on sth May 

 one pupated, and gave imago 12th May. 



In 18S9, on 30th August, or five weeks later than in preceding year, 

 I received eggs. Between the 23rd and 30th of September, all the larvae 

 were in hibernation after only two moults. The same year a second lot 

 of eggs came ist September. The larva hibernated after second moult. 



In 1-890 eggs were received 8th August ; nearly all the larvae hiber. 

 nated after second moult, but a few went to third and one to fourth, but
