OWLET-MOTHS. 169 
with numerous whitish dots. On reaching maturity the 
larva selects a leaf and drawing together a portion of it 
with silken threads forms a sort of hollow tube. In this it 
makes a very slight silky cocoon, inside of which it trans- 
forms to a brown chrysalis. We seem to have two annual 
broods, the last one of which winters in the pupal stage. 
The caterpillar is shown in Fig. 170, Plate XIX. 
The small moth, which expands only three-quarters of an 
inch or a little more across, has fore-wings of an ashy-gray 
color, which are whitish towards the margin, crossed by 
three irregular, black lines, which are faint and indistinct 
towards the inner edge; near the middle of the wing there is 
frequently a round and whitish spot with a black dot in the 
center. The hind-wings are dull whitish, dusky towards the 
tips. Beneath both wings are of a silvery-whitish hue, 
sprinkled with blackish dots towards the outer edges. 
These caterpillars feed on the cherry, plum, elm, poplar 
and other trees, but seem to be partial to the apple and 
shadberry. 
THE UNIFORM WHITE-SPOTTED SCOPELOSOMA. 
(Scopelosoma sidus Gu.). 
This is one of our very earliest moths, examples having 
been caught as early as March 15th. The moths are readily 
attracted to sugar baits, and come in large numbers until 
about the middle of April, when they gradually disappear. 
In captivity they readily deposit yellowish-white eggs, per- 
fectly globular, and ornamented with numerous fine ridges. 
Before the eggs hatch theychange to a light brownish color. 
The caterpillars have a bright honey-yellow head, and the 
cervical-shield, which is very prominent, is polished black. 
The thoracic and first abdominal segments are brownish, 
the dorsal space is light green or whitish, with the median 
line and subdorsal stripe white; a brown line above the
