894 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
moths in Jane and July; these at onoe deposit eggs which give the 
second brood of moths in September. The female lays about fifty eggs, 
and those observed by Mr. Lintner hatched from April 5 to 30. 
Egg. — Gloesy reddish brown, i»r<»:i«l ly oval, ■omewhAt flattened upon its attached 
Bide/about 0.05 inch long by 0.04 inch broad; the surface, under a magnifying power 
of fifty diameters, shows irregular hexagonal reticulations, of which the elevated 
lines are divided by a line impressed line. The shell is moderately thick. The larva 
eat! an opening m one end of sufficient size for its escape, but in some instances a 
portion of the shell is subsequently eaten. The eggs laid under my observa- 
tion have been so covered with the anal hairs of the moth as almost entirely to hide 
them from sight. Fig. ir> * represents a cluster of them. 
Larva, firxt stage. — The larva, on emerging from the egg, measures one-tenth of an 
inch in length, is of a dull green color, with a black dorsal line. The head shown in 
Fig. 16, enlarged to six diameters, is brown, crossed centrally by a white horizontal 
line, another shorter one beneath parallel to it, just above the mouth-parts, and two 
nearly perpendicular ones on the superior front of the head, obsoletely united below 
by a curved line. Rows of tubercles traverse the body, from which long hairs pro- 
ceed, of which those of the first segment are longer than the body, and those on 
the terminal segment are as long as the body. The legs are long and project later, 
ally — more conspicuously so when the caterpillar is walking. Twelve of the larva 
died during this stage before attaining their first molting. Their greatest leugth 
was one-fourth of an inch. This stage was of varying duration, extending from 
sixteen to thirty-three days. 
Larva, second stage. — The first molting commenced on April 21st, and terminated on 
the 8th May, extending over seventeen days — a considerable less range than that 
shown in the hatching of the eggs (17:25). The following is the record of the 
observed moltiugs:

On emerging from its first molt the larva measured 0.3 inch. The frontal lines of 
the head, before nearly perpendicular and parallel, uow converge below, resembling 
the letter JJ ; the brown portions, under a lens, show indistinct mottlings (see Fig. 
17). The body tapers regularly from the first to the last segment. The dorsal line 
is brown, with pale borders. On the summit of the third segmeut is a fuscous patch, 
behind which extendiug over the incisure, is a pale patch, convex in front and 
straight behind, bounded by the four tubercles of the fourth segment. On the sev- 
enth segment is a small pale pptch. The sides of the body are gray, with irregular 
linings; a sub-dorsal row of black tubercles bear several long black hairs, beneath 
which is a dull orange interrupted line. The tubercles of the substigmatal row bear 
numerous shorter white hairs. 
During their rests from feeding the larva 1 resort to the stems, where, with flat- 
tened body pressed to the surface and with head extended, they can scarcely be 
discovered. 
At the close of this stage, which rauged from seven to eighteen days, the larvae 
measured one-half an inch in length.
