mountain country, and so continued till September." In Mr. Mead's Re- 

 port on the Lepidoptera taken by the Wheeler Expeditions, 1875, it was 

 farther said of Charon : " It was found both in South and Middle Parks, 

 though not so abundantly as in the Arkansas Valley. In August, females 

 were obtained and inclosed with grass ; several eggs were laid ; they are 

 whitish and very similar to those of Nephele.^^ I do not know that 

 another line has been published on the habits of this butterfly than what 

 Mr, Mead wrote or authorized as above, although the species has been 

 taken in many localities from New Mexico to Montana, and even in 

 British America, as appears by Captain Geddes' list. Mr. Morrison also 

 took it in Nevada. 



I received 20 eggs of Charon from Mr. H. W. Nash, then at Rosita, 

 Colorado, 4th August, 1S84; on the loth August, 23 more, and many 

 others on 14th Aug.; sent through the mail, in turned wooden boxes, the 

 eggs all obtained by confining females in bags over grass. They came in 

 perfect order, and began to hatch, the ist lot, loth Aug., the and lot, 17th. 

 The larvae were remarkably like those of Alope, same shape, color, longi- 

 tudinal bands and processes, and the latter were bent like fish-hooks, just 

 as in Alope. I had larvae of Hipparchia Ridingsii hatching at same time, 

 and the difference between them and the larvae of Charon at this stage 

 was striking. It was generic. The same resemblance to Alope runs 

 through the whole history of Charo?i, egg, all the larval stages, and the 

 chrysalis, except that in color this last is variable as to coloration in 

 Charo?i, and not in Alope. 



The larvae devoured the egg shells more or less comjDletely, but eat no 

 grass, and settled themselves for a winter's sleep. I left them for several 

 weeks in the cellar, in paper pill boxes. On loth October, they were sent 

 to Clifton Springs, New York, and placed in the " cooler " of the Sani- 

 tarium there, temp, all the year 40° Far. On 7th March, 1885, 1 received 

 the larvae again ; nearly all were alive, and they were placed on a sod of 

 grass set in flower pot, and covered by a glass lamp chimney. On 8th, 

 several were feeding. The first larva passed ist moult 29th March, b^t 

 several were ready to pass this moult for about a week had the weather 

 been pleasant, instead of cold, cloudy and stormy, much of the time. 

 Two more passed the moult 2nd April. The last one of 15 larvae passed 

 ist moult 15th April j so that between the first and last was an interval 

 of 17 days.
