MOTHS AND BUTTERFLIES. 
SA TYRIDjE. 
Wood Nymphs. Browns. 
The family Satyridoe contains a number of medium sized, plain 
colored butterflies, mostly of different shades of brown, whose only 
ornamentation usually consists of numerous eye-like spots, most dis- 
Larva of Satyrus. 
tinctly traced on the underside. The larvse are cylindrical, tapering 
toward both ends, particularly the hinder extremity, which is termi¬ 
nated by two points. They are usually covered with soft, short 
hairs, springing from minute warts. Many species feed on grasses. 
The chrysalides are not angular, differing in this respect in a striking 
manner from those of the succeeding family. They are usually sus- 
Clirysalis of Satyrus. 
pended by the tail from a silken mat, although sometimes they are 
found loose among leaves on the ground. Like the Nymphalidce 
they lack the silken thread passing around the body, which is the 
principal characteristic of the Papilionidce. The perfect insects 
possess but four well-developed legs, the forward pair being almost 
aborted. Their wings are broad and rounded at the ends, and their 
bodies are small and weak. They are sometimes seen in great 
numbers, and are most often found in or near wooded tracts. Their 
flight is slow, and most of the species are easily taken with the net. 
Our first example of this group, Cliionobas semidea , is an insect of 
great interest to the entomologist, on account of its probably being 
a survivor of an arctic pre-glacial species, driven to more southern 
latitudes by the cold of the ice age, and later having advanced up the 
mountain sides as the ice sheet gradually melted, being thus cut off 
from a retreat to its former northern habitat by intervening regions
