inch above ground, in an angle formed by three leaves. As I cut one 

 of these, it turned over and fell, showing itself to be unattached. In fact 

 the cremaster was found to be furnished with but straight bristles, very 

 short, and there were no hooks by which attachment could be had. As 

 before stated, a male of the typical form came from this chrysalis on 12th 

 May. 



I had received young larvae of this species from Mr. Bean, at Laggan, 

 25th July, 1886, they having hatched en route. I lost all but one of these. 

 It passed first moult 2d August, the second moult loth i\ugust, and soon 

 after became lethargic. I kept it at Coalburgh, and brought it into the 

 house middle of January, 1887, apparently healthy. But a month later it 

 unaccountably disappeared. 



Mr. Bruce had also sent eggs from Colorado which reached me ^8th 

 July, 1886. From these, five larvae reached second moult, and went into 

 hibernation, and died during the winter. From the behavior of the differ- 

 ent lots of larvae, it apears that hibernation may take place at either second 

 or third moult. 



This, therefore, is the complete history of an Erebia from egg to imago, 

 and, so far as I know, the first such that has ever been published of one 

 of the genus. To get drawings of the several stages, it was necessary to 

 send them to Mrs. Peart, at Philadelphia, through the mails, some five 

 hundred miles, with risk of loss or damage. Indeed, the second larva 

 was in Philadelphia in its last stage, and being returned to me, imperfectly 

 pupated on the way, and died. 



The genus Erebia comprises many species, nearly all of which are 

 European and Asiatic. Dr. Staudinger, in 187 1, enumerated forty-eight, 

 many of them boreal, others alpine, the latter found as far to the south as 

 the Pyrenees, Alps, Caucasus, and Himalayas. Great Britain is credited 

 with three species, and, in Buckler's Larvae of British Butterflies, Vol, I, on. 

 Plate VI, are figured the mature larva and pupa of one of these, E. Blaii- 

 dina, and the young larva of another, E. Cassiope. In the text, Mr. 

 Buckler relates tfiat he raised the larva of B/andina from the egg, obtain- 

 ing pupa and imago ; and a brief description of the several stages is given, 

 that of the larval being imperfect, as nothing is said of the several moults. 

 Nor is it told how the larva pupated. Nevertheless, the plate represents 

 the pupa resting nearly upright on a tuft of grass, but not at all inclosed. 

 It looks very much like the pupa of Epipsodca. So an incomplete des-
