Description of the stages” 
The egg (Plate XLVI, 61) 
Flat; saucer-like or shell-like in shape, and grayish white in color. Diameter, as seen — 
from the top, varying from 0.89 to 1 mm.; thickness of egg about 0.2. Sculpturing very — 
pretty, micropyle in center of dorsal surface consisting of a dot with a rosette of elongate | 
cells around it. Radiating from the rosette to the margin of the egg, about 45 small ridges, 
indented transversely by small, rounded depressions. 
The larva— The first-instar larva, within twenty-four hours after 
hatching, is described as follows: 
Length 2mm. Entire head jet black; thoracic shield dark brown; meso- and metathorax — 
light gray with dark tubercles. Segments 1, 4, 5, and 8 of the abdomen dark brown, with 
gray tubercles. The other segments of the abdomen light yellow, with gray tubercles. From 
these gray tubercles originate long hairs. 
Beutenmiiller (1901) gives the following description of the full-grown 
larva (Plate XLVI, 62): 
Head black, with an inverted V mark on the face, two white stripes on top, and mottled 
with white at the sides. Body black, two yellow lines on each side of the back and one 
on each side below the spiracles. The body is also mottled with confluent striae, but less 
so on the dorsum. Warts orange with light and dark bristles; along the extreme sides a row 
of orange spots. Underside pale whitish. Length 40-45 mm. 
The pupa (Plate XLVI, 63) 
Length 18 mm., width, 5 mm. General color dark brown. Wings extending as far back 
as the fourth abdominal segment. Front of the head with two rounded, rugose ridges running — 
up and down. Clypeo-labral suture very distinct. The front margin of the labrum rounded. 
Labial palpi three times as long as the undivided labium. Maxillae extending down to the 
beginning of the third abdominal segment. Prothoracic femur visible and the prothoracic 
tibia and tarsi extending down almost to the tips of the maxillae. Mesothoracic legs extend- 
ing to the middle of the fourth abdominal segment. Antennae just failing to reach the tips 
of the mesothoracic legs. _Metathoracic tarsi plainly visible. Ventral surface of segments 
5, 6, and 7 finely granulate anteriorly, posteriorly finely punctate. The other segments 
smooth. On the dorsal surface, the metathorax and the first seven abdominal segments 
very roughly tuberculate. Cremaster broader than it is long and bearing from 40 to 50 
short, straight spines. 
The adult.— The adult (Plate XLVI, 64) is described as follows by. 
Beutenmiiller (1901): ‘‘ Fore wings white, and more or less heavily 
marked with fawn brown streaks between the veins, giving the insect a 
very characteristic appearance. Hind wings and body white. Expanse, 
34-45 mm.”’
