lo days. Whole period from laying of egg to imago, in summer, 49 days^ 

 of which the egg was 12 to 13, larva 25 to 26, chrysalis 10. 



After the second and third moult, which took place last of June and 

 early in July, all the larvae but the one which went to pupation 30th June, 

 became lethargic, and evidently would hibernate. I put four of these on 

 ice, 26th July, and nine others, 4th August, to see if some weeks of that 

 treatment would not serve for their resting period as well as the entire 

 winter, with ordinary exposure. On 23rd August, I brought in one of the 

 first lot, on ice four weeks. This had passed three moults. On 24th, it 

 began to eat ; on 26th, was .48 inch long ; grew slowly and eat at long 

 internals. By 20th Nov., was .56 inch; and passed the fourth moult 2nd 

 December. On 30th Dec, pupated. The pupa I put in alcohol. Another 

 larva passed 4th moult, 6th January. Another same, 17th February. This 

 last pupated 23rd May, and gave imago 3rd June. So that the exposure 

 on ice, though it more or less fully aroused the larvae, does not seem to 

 have shortened the hibernating period, except in case of the single one 

 which pupated 30th December. 



The eggs of Ampelos were sent me by Mr. James Fletcher, then at 

 Victoria, V. I., and were laid 22nd May, mailed 23rd, and reached me 

 3rd June. The first larva hatched 4th June. 



On 2ist June, I received a second lot, or rather, young larvae just 

 hatched, and two eggs. These were laid on 9th and 16th June, and were 

 mailed nth. In both cases the females which laid the eggs were sent. 



There seems to be no dimorphism in this species. The butterflies 

 which came from chrysalis with me did not differ from the parents, and 

 examples sent, taken in May and in August, were of the one type. Mr. 

 Fletcher informs me that this was his experience. This species is of the 

 size of C. Ochracea (smaller than Gaiactmus), of a paler color j the 

 under side of hind wings gray brown, sometimes paler beyond disk, some- 

 times of one shade from base to margin ; with an interrupted, irregularly 

 crenated band across disk ; with no other mark, no spot towards base, no 

 ocelli or spots along hind margin (all these spots are characteristic of C. 

 Ochracea). Mr. Fletcher writes : " I have never succeeded in finding an 

 ocellus, and I am sure I have examined hundreds of examples." He also 

 adds that the species is extremely abundant at Victoria. 



Avipelos was described by me, 187 1, in Tr. Am. Ent. Soc, from a pair 

 received from Oregon. So that it probably is found at least from Oregon
