ber of eggs deposited ranges from 300 to 600. The eggs hatch in 
4 to 8 days. 
Lagoa crispata Pack., is more commonly found in the Northern 
States than in the South. The moth is cream-colored and the fore- 
wings are marked with wavy lines of crinkled black and brownish 
hairs. The larva is cream white when young, and fawn, shading 
to mouse gray in front, when full grown. It has a wide variety of 
food plants including bayberry, sweetfern, locust, apple, and many 
others. According to Bishopp (29), its stinging propensities are not 
highly developed. Apparently this species has only one generation, 
and the larvae are found from J uly to September. It passes s the winter 
as a prepupal larva in a tough cocoon. 
The moth of Vorape cretuta (Grote) is pure white with a little 
crinkly hair. The wing expanse is about 114 inches. The larva has 
a spotted body, sparsely clothed in tufts of hair. During the early 
instars the larvae are gregarious. Pupation takes place in tough 
cocoons in the ground. This species feeds on redbud, and ranges from 
New Jersey and southern Pennsylvania southward, at comparatively 
low elevations. Sometimes it is rather abundant in the vicinity of 
Washington, D. C. 
Famity PYRAUSTIDAE 
The Pyraustidae is a large family, which until rather recently has 
been considered by most students of Lepidoptera as a subfamily of 
Pyralididae. The moths are small to medium size, rather slender 
and fragile in structure, and some are striking in appearance. A1- 
though there are many species common to the eastern part of the 
United States, comparatively few of them live on trees and shrubs in 
the forests. The larvae are generally very active and of varied habits; 
some live gregariously in webs among the leaves, some are solitary and 
live in rolled or folded leaves, and others are borers in stems or roots 
of plants. Occasionally larvae bore into the woodwork of buildings 
to pupate, and thereby disfigure painted surfaces. 
The moth of the grape leaf folder (Desmia funeralis (Hbn.)) is 
black with white markings, the forewings in both sexes have two large 
oval spots, and on the hind wings of the male there is one spot. In 
the female there may be a divided spot on the hind wing. The fringe 
of the wings is more or less white. The wing expanse is about 34 to 1 
inch. The full-grown larva is about 1 inch in length, glossy, translu- 
cent yellow-green on the sides and somewhat dar ker above. The head 
and cervical shield are light brown, and there are darker brown spots 
on the sides of the first two thoracic segments (Strauss, 398). 
This species is distributed in Canada from Nova Scotia to Ontario, 
and in the United States east of the Rocky Mountains, and in Cali- 
fornia. It is a, well-known pest of grapevines. The food plants in- 
clude wild and cultivated grape, Virginia creeper, and redbud. There 
are two or more gener ations in the South, but there may be only one 
in its northern range. The moths emerge in the vicinity of Washing- 
ton, D. C., from late in April through most of June, and late in July 
and August, and larvae may be found until October. In Massachu- 
setts, moths emerge in June and the larvae are active in July and 
August. The winter is passed in the pupal stage on the ground.
