EREBIA I. 



before the middle of the segment ; on 13 are six in two rows made up of the dorsal 

 and sub-dorsal, which fall nearly into line, a lateral on either side in front, and 

 six around the end, these last smaller and with shorter processes ; the processes 

 on 2 are decidedly club-shaped (Fig. c) ; on the other segments to 12 scarcely 

 clubbed (Fig. c^) ; on the sides of all moderately clubbed, and short (Fig. c^) ; on 

 13 the four uppermost are cylindrical and long (Fig. c*) ; along base a row of 

 minute tubercles with short hairs, two to each on 2, 7 to 13, one on each of the 

 rest ; color at first pink-white, with a brown mid-dorsal stripe, and three brown 

 lines on the side ; a few days later the dorsum had a green tint ; later the ante- 

 rior half became greenish, the rest j^ink-white ; under side, feet, and legs paler ; 

 head a little broader than 2, ob-ovoid, the top a little depressed ; color black- 

 brown, surface granulated ; marked by a few low tubercles, each giving a white 

 process. (Figs. 6-6^.) This larva died before a moult. 



Vei-y few examples of this Erebia are to be found in collections, and all, so far 

 as I know, have been taken by that indefatigable lepidopterist, Mr. David Bruce, 

 of Brockport, New York. Mr. Bruce wrote me, July 15, 1887 : " I have just got 

 in from the mountains after a hard struggle. The rainy season has commenced 

 a month earlier than usual, and consequently there is no depending on anything. 

 I have been on Bullion Mountain, 14,000 feet, for nearly two weeks, have taken 

 five Magdalena, a good series of C. Bore, also of Semidea. I send you two eggs of 

 Magdale7ia." These were laid 10th July, and one hatched on 22d. The other 

 was put in alcohol, that its likeness might be drawn. The larva at first seemed 

 lethargic, and I tliought it would sleep as the larvte of the genus Satyrus do, 

 and so pass the winter. But on 26th I noticed that it had eaten of the grass 

 on which it rested, and had changed color, as small larvae usually do after feed- 

 ing. On 28th I sent it to Mrs. Peart, at Philadelphia, and learned that it died 

 there a few days later, and before a moult, attacked by mould. 



Later, Mr. Bruce kindly wrote out his observations on this species, thus : 

 " E. 3Iarjdalena is found in the most uninviting- looking spots it is possible 

 for a naturalist to explore. Black, barren, detached rocks, that look as if an 

 immense peak had fallen and split into fragments ; hardly a blade of grass or 

 a patch of lichen to relieve the utter desolation. Yet even here, animal life 

 is found in plenty, and fitted for such a dwelling-place. All day long can be 

 heard the singular ' keek ' of the ' Little Chief ' Hare, Lagomys princeps, and 

 until the animal is seen, the stranger is puzzled to know if it is the voice of a bird 

 or an insect, on the earth or in the air ; yet the little ventriloquist is sitting on a 

 rock probably within a yard of his feet. A loud shrill whistle announces the
