of silk. They remain in their cocoons without further 

 change throughout the winter, and are transformed to but- 

 terflies in the following summer. The viscid locust-tree is 

 sometimes almost completely stripped of its leaves by these 

 insects, or presents only here and there the brown and 

 withered remains of foliage, which has served as a tempo- 

 rary shelter to the caterpillars. 



Eudamus Bathyllus, Smith. Bathyllus Skipper. (Fig. 135.) 



In Massachusetts we have what I suppose to be only a 



local variety of the Bathyllus

This species is found on flowers in June and July ; in the 

 Southern States it appears also in March and April. The 

 caterpillar is very similar to that of the Tityrus skipper, and 

 is found on various kinds of Glycine, Hedysarum, &c, in 

 May and June. 



The rest of our skippers belong to the old genus Hesperia 

 of Fabricius, which, as now restricted by the French ento- 

 mologists, very nearly coincides with Pami^hila of the Eng- 

 lish writers. The American species are quite numerous, 

 and moreover vary a good deal ; wliich, with the difference 

 existing between the sexes, renders it quite difficult to deter-
