690 THE BUTTERFLIES OF NEW ENGLAND. 



With few exceptions, such as Cissia, Eurymus and some Melitaeidi, 

 all other hibernating caterpillars pass the winter in some sort of a nest. 

 Most of them, separately or collectively, in one which has already given 

 them protection during their partially completed larval life, but generally 

 specially strengthened or enlarged for the purpose and almost always with 

 all approaches closely sealed. The species of Basilarchia are the only 

 ones amonf New England butterflies which construct hibernacula properly 

 speaking, i. e., nests for the special purpose of wintering in them, and 

 which they use at no other time. Here each individual makes for itself 

 its separate nest. Euphydryas, however, alters and strengthens its social 

 nest for the winter to such an extent that its appearance is then quite dif- 

 ferent, and in the centre, as the nest contracts with the withering of the 

 leaves, the caterpillars are crowded together into almost a solid mass. The 

 other larger caterpillars which make no nest probably seek merely some 

 cranny upon or near the ground wherein to lie concealed during the winter. 

 We find, therefore, no little variety among our native butterflies even in 

 such an apparently simple matter as the hibernation of the caterpillar. 



*** Some facts concerning the hibernation of the caterpillars of European butterflies will 

 be found collected in Prittwitz's paper, heretofore alluded to (Stett. ent. zeit., xxii:191).

Imago (5:2; 12:2). Head covered rather thickly with short, black or brownish 

 black hairs, slightly tinged Avith olivaceous, with a few yellowish hairs next the outer 

 base of the antennae in front, a minute, lunate patch of yellow hairs at the back of the 

 head, directly behind each antenna, opening toward the opposite one, and, occasionally, 

 a few scattered yellowish scales down the front ; a narroAV patch of yclloAvish white 

 scales, broadening beneath, along the inferior half of the hinder border of the eye.
