streak of brown on dorsum at base and the apex of the wing is lightly 
reticulated with this color. Cilia light brownish ochreous on costa and 
upper half of termen, becoming pale fuscus below middle. 
Hind-wing. Light fuscus, cilia with a faint ochreous tinge.”’ 
Pupa—About 4 mm. long by 1.3 mm. wide (Fig. 4, Pl. XVIII). 
General color greenish, becoming brownish toward maturity. Eyes 
reddish in mature pupe. Head, tip of wing pads, tip of abdomen, and 
5th, 6th and 7th abdominal segments darker than the rest of the body. 
General shape cylindrical with abdomen pointed, ending in about seven 
or eight stout, black spines and reaching a little beyond wing pads. 
Head bears two conspicuous setz on each side of the top, two sete on the 
front, just laterad of the eyes, and one on each side of the back of the 
head. <A row of eleven smaller setze on the center and on each side of 
the dorsum. Six spiracles visible. 
Larva.—Length 7 mm. by 1.5 mm. wide (Fig. 1, Pl. XVII). Head 
brownish, ocellar area, anterior margin of head, and a fine line extending 
from the ocellar area to the first segment, dark brown. The anterior half 
of the thoracic and the first eight abdominal segments with an orange- 
colored band which is more prominent on the dorsal half. The bands of 
the second and third thoracic segments are somewhat narrowed on the 
dorsum while that of the first thoracic segment 1s lighter. The last two 
segments suffused with red, nearly all over. The remaining portion of 
the body of the larva is yellowish. Some of the larvae, however, show 
very little of the orange color on them. The mandibles are strong 
bisetose and quadridentate, the two inner teeth being the larger (Fig. 2, 
Pl. XVII). The antenne are three-segmented and borne on a fleshy 
membranous cone (Fig. 3, Pl. XVIII). The first segment is wider than 
long while the second segment is slightly longer than wide, truncate, and 
bears a long seta on each side of its apex as well as a small spine and two 
tubercles, which are about three times as long as broad. The minute 
third segment is borne on one side of the center, the apex of which bears 
three small spines and two tubercles, one of which bears a seta and is 
half as long as the other. The arrangement of the sete on the third 
abdominal segment is shown in the diagram (Fig. 7, Pl. XVII). The 
hooks of the pro-legs and spiracles are brownish, the latter surrounded 
by a small, circular, yellowish area. The thoracic legs are large at the 
base but taper rapidly (Fig. 3, Pl. XVII). The first eight abdominal legs 
are wart-like, ending in about nine hooks that are arranged in a circle, 
somewhat open on the outer end (Fig. 5, Pl. XVII). The number of 
hooks seems to vary, thirteen being the highest number found. Pro-legs 
have about seven hooks. There are nine spiracles, one on the prothorax 
and one on each of the first eight of the abdominal segments, located in 
the middle of the orange-colored band. 
FEgg—tLength 0.33 mm. by 0.2 mm. wide. Shape oval; color, 
greenish white, with a tinge of purple. The eggs found on the stem are 
somewhat flattened on the under side, but less so when found on the 
scales of the berry. The surface of the egg is covered with numerous 
wavy ridges (Fig. 7, Pl. XVIII).
