BOMBYCIDS.

are gayly colored. When mature they spin a tough oval or nearly 
spherical cocoon attached to the twigs of the food plant, oak, walnut, 
birch and other forest trees furnishing them with food. The moth 
emerges from the cocoon by pushing off one end, leaving the side 
attached like a half-spherical lid. 
Limacodes scapha is a prettily marked little moth expanding 
about an inch. The body and lower wings being cinnamon-brown, 
and the upper wings having a rich reddish-brown patch covering 
most of the upper part of the wing, edged with silver beneath. The 
rest of the wing is light brown. The larva is green, without spines, 
short, thick and high in the middle. It feeds on the oak. 
Limacodes querceta. 
Another prettily marked insect is Limacodes querceta. It is 
reddish-brown with a small dot of dark brown in each fore wing, and 
a broad, irregular patcli of light green extending from near the lower 
margin next the body diagonally across the wings to near the tip. 
Parasa fraterna. 
The caterpillar lives on the oak and willow, is yellow and purple in 
color, and lias a number of branching, pointed- filaments which spring 
from its back and sides. The moth makes its appearance in July, 
and often comes into our rooms at night attracted by the light. It 
is a rapid flyer for so small a moth, its short wings humming with 
the rapidity of their motion.
