548 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
palfl watery pink color, and covered with short, blunt spines, from which arise short 
fine hairs. The surface of the body is somewhat granulated, especially on the for- 
ward segments and behind the caudal horn. 
Tht tliird molt is made in from four to six days, after which the larva is about 1 
inch ion-, of a light green color, rather lighter than the under side of the lilac leaf 
00 which ii feeds. There is some variation of the ground color at this stage; some 
arc yellowish green while others incline to a bluish green. The longitudinal stripes 
are now obliterated and the oblique stripes are as in the preoe'ling molt. The legs 
and caudal horn are pink or pale vinous red, the latter beset with short Stout spine.-, 
as before. The headland three following segments have whitish granulations above, 
while the last segment has black granulations on the upper side. The head has I 
broad vertical stripe of a dull whitish color ou each side. The spiracles are pale 
pink with a white dot at each extremity. 
The fourth and last molt is made iu from seven to teu days, after which the larva 
is about oue iuch aud three-fourths in length and of the same color as in the preced- 
ing molt. The stripes ou the side of the face, the caudal horn, and the legs are pale 
pink or flesh color. The last segment is sprinkled with hlack granulations on the 
upper side, aud the spiracles are bright vennillion with a vertical white slit in the 
middle. The oblique stripes are greenish white. The larva reaches maturity in 
from eight to twelve days from the fourth molt, aud is nearly 3 inches loug. It 
now changes to a dull brownish color which somewhat obscures the markings, wheu 
it descends to the ground, and working its way down into the soil, transforms into a 
dark brown pupa one inch and three-fourths long, with the tongue-case sunken to a 
level with the surface. 
Moth. — Expanse of wings, 3| inches. Head and palpi brownish gray, the latter 
being darker on the middle joints, and the head darker above and lighter on the 
sides. The thorax is gray with two black lines edged with yellowish crossing the 
prothorax. These lines meet two similar ones on each side, which run backwards, 
one on each edge of the patagire and meeting behind where the patagia is tipped with 
white. There is also a curved black line preceded by white and followed by yellow- 
ish across the hinder part of the thorax. The abdomen is gray with a dark brown 
line along the middle and two stripes of the same color on each side and the seg- 
ments are edged with yellowish scales. The whole under side is gray with the breast 
of a pale coffee-brown color. 
The forewiugs are gray, mixed with yellowish scales and crossed by four pairs of 
wavy or augulated dark browu lines more or less distinct, which start from the costa 
at about equal distauces apart, and divide it into five nearly equal parts. The pair 
nearest the base of the costa runs obliquely as far as the cell, giving off one tooth, 
then it takes a somewhat wavy course to the hinder margin nearly at right augles 
with it. The second pair is distinct on the costa but crosses the wing a little within 
the discal spot, as a dark brown shade. The third pair starts at right angles with 
the costa, and curving around the end of the cell, ends near the middle of the hinder 
margin. The inner of these two lines is slightly augulated while the outer one gives 
off quite long and sharp teeth, and the space between them is filled in somewhat 
with ocher-yellow scales. Between this and the outer pair of lines the space is tilled 
in somewhat with whitish. The outer pair of lines starts at right augles with the 
costa, curves evenly around to vein 2, and then runs straight to the hinder margin. 
The outer one of this pair is the darkest and most prominent of all, and is neither 
undulated nor toothed, while the inner one gives off acute angles on each vein. A 
black shade line, starting from the apex obliquely, extends into the third pair of 
cross-lines. A parallel dash crosses the outer pair just below, and there are two 
parallel black dashes near the middle of the wing extending from the median vein 
out to the outer pair of lines between the veins. The fringes are white, marked on 
the veins with dark-brown spots from which brown dashes extend nearly half-way 
across the terminal space.
