WOOLY BEARS. 87 
brownish streaks passing backwards from the front edge, 
with three rows of yellowish-white, semi-transparent spots 
parallel to the outer margin. The hind-wings are very thin, 
transparent and without spots; the shoulder-covers are 
edged with light brown. The moths expand from one inch 
and seven-eighths totwoinches anda quarterand more. At 
rest the wings are roofed; the antennz are long, with a 
double, narrow, feathery edging in the males, and a double 
row of short, slender teeth on the under side in the females. 
These antenne are rather longer than usual in Arctiids, and 
are not at all hairy. The tongue is a short spiral. 
Another species of closely allied tussock moths is some- 
times found feeding upon the foliage of plums; the more us- 
ual food is, however, the scarlet-oak. This moth is called 
Halesidota muculate Harr., or the Spotted Tussock moth. 
It is of a light ochre-yellow color, with smaller and almost 
white spots arranged in about the same manner as the yel- 
lish-white spots in carye. The moth is a little smaller than 
the species described before. All three moths are shown on 
Plate XXI, Figs. 84 and 85. 
THE CHECKERED TUSSOCK-MOTH. 
(Halesidota tesselata S. & A.). 
The caterpillar of this species is even more common, 
being found not alone upon the oak, but also upon plums, 
apples, raspberries and blackberries. In general appearance 
it is like cary, but the tufts are yellow, and the crest is a 
little darker; on the second and third segments are two 
orange-colored pencils, which are stretched over the head 
when the insect is at rest, and before these are several long 
tufts of white hairs; on each side of the third segment is a 
white pencil, and there are two pencils of the same color 
directed backwards, on the eleventh segment. The body is 
yellowish-white, with dusky warts, and the head is brown-
