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 

 skipper, differing from South- 

 ern specimens in the inferior 

 size of the white spots on the 

 fore wings, the less prominent 

 hind angle of the hind Avings, 

 and the darker color of the 

 frino;es. It is of a dark brown color ; on the fore wino;s is 

 a row of small white spots across the middle, and another 

 shorter row of only three or four contiguous spots between 

 the first and the tip ; the wings beneath are light brown, 

 shaded at the base with dark brown ; the hinder pair with 

 a slightly prominent posterior angle, and two dark brown 

 transverse bands. 



Expands from 1| to lyV inch. 



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 G-lycirie, Hedysarum, &c., in 

 May and June. 



The rest of our skippers belong to the old genus Hesjyeria 

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

 mologists, very iiearly coincides Avith Pampldla of the Eng- 

 lish writers. The American species are quite numerous, 

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

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