NEW ENGLAND CATERPILLERS, NO. 2. EUBAPHE 

 NIGRICANS REAKIRT. 



By Wm. T. M. Forbes,

Eubaphc opclla has been described by Dyar in Psyche, VIII, p. 

 119. and in Hampson's "Catalogue of the Lepidoptera Phalaense 

 in the British Museum," Vol. Ill, 193. . E. aurantiaca. the other 

 known caterpillar of the genus, is described in the Proceedings of 

 the United States National Museum, XXV, p. 374, and must be 

 quite different. Nigricans is also entirely different from opella in 

 color, to judge merely by the single specimen bred. Of course the 

 variation may be individual, but it would suggest the possibility that 

 nigricans is a distinct species from opclla. In my " Field Tables " 

 nigricans will come out in alternative 142, with Amnialo cglenensis 

 on superficial characters. The latter has paler (?), feathery hair, 

 and there is not the conspicuous caudal tuft. They should also occur 

 at dift'erent seasons, since nigricans pupates early in May and evi- 

 dently hibernates as a caterpillar.
