10 days, the larvae feed during June, July, and early August, and the 
winter is passed in the pupal stage in the ground. MeDunnough 
(286) recorded adults emerging in confinement late in August and 
early in September. 
Anacamptodes ephyraria (Wlkr.) is found on hemlock in the North- 
eastern States. The full-grown larva is 7% inch in length. The head 
is broader than the thorax, brown, and balaped! The body i is greenish 
tinged with reddish-brown, the second abdominal segment “usually 
having a prominent swelling on each side. The larvae feed from 
May to J uly and the moths emerge in August. A. larvaria (Guen.) 
is found on poplar in the New England States. The full-grown larva is 
114 inches long. The head is brown and quadrate. The body is yel- 
lowish green, with a reddish band on the second abdominal segment, 
a series of broad irregular reddish blotches on the back, and a pair 
of blunt tubercles on the back of the eighth abdominal segment. The 
larvae feed from July to September, the winter is passed as pupae 
in the ground, and the moths emerge in June. 
The full- grown larva of Ectropis crepuscularia (Schiff.) is about 
114 inches in length. The head is brownish and somewhat mottled. 
The body is reddish to chocolate brown, with a pair of blunt tubercles 
on the top of the eighth abdominal segment. The food plants include 
the foliage of birch, maple, oak, walnut, and other deciduous trees and 
shrubs. The larvae are found from May to September, and the adults 
have been recorded late in April and May, late June and July, and 
in October. The winter is passed in the pupal stage in the ground. 
Epimecis virginaria (Cram.) is the largest moth of the family in 
the eastern part of the United States. Tt has a wing expanse of 
about 2 inches and varies greatly in color. Some color forms are 
light gray dusted with brown, the forewings with five well-marked 
lines, and other forms are dusky or almost black with the markings 
indistinct. The full-grown larva is stout and about 114 inches long. 
The head is small and reddish brown, the body yellowish to dark 
brown, and marked with many fine, irregular, wavy, longitudinal, 
pale yellowish lines, and the venter and legs are yellowish to light 
brown (fig. 91,@). This species is recorded from the Atlantic States. 
Some authors have reported it very common in Florida, and state that 
the larvae feed on yellow poplar. <A local outbreak occurred in Con- 
necticut, defoliating a small area of sassafras in 1936. In this in- 
festation the larvae were active in June and July. They fed at night 
and the nearly full-grown larvae were found in the duff beneath the 
trees during the day time. The pupae were formed in the ground. 
Some moths emerged from late in August to late in October, ‘but the 
majority hibernated as pupae. and the moths emerged in May and 
June. This indicates that where conditions are suitable there may be 
a partial second generation. 
The full-grown 1 larva of V acophora quernaria (A. & §.) is 2 inches 
in length and slate gray. The head is angular and bilobed, and the 
body is stout, with many brownish wartlike tubercles. The backs of 
the first two thoracic segments are marked with reddish brown and 
black. The segments of the body are somewhat swollen, this condition 
being particularly noticeable on the tops and sides of the second thora- 
cic and second abdominal segments and the venter of the third segment.
