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 BathyUus , Smith. Bat liy 11 us 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 wings, 
and the darker color of the 
fringes. It is of a dark brown color ; on the fore wings 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 h to 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 Glycine , Iledysarum, &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 PampMla 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-
