tenth abdominal segment), single dorsal on joint 12; row 2 lateral 
on joints 2-12, stigmatal on joint 13; row 3 substigmatal on joints 2-12; 
row 4 subventral on joints 2-6, smaller than the others. Color entirely 
black ; but, as the stage advances, a large orange patch appears around 
the base of each process except those on joint 2 and the dorsal one on 
joint 12. These spots tend to run together, fox'ming incipient bands. 
Length 5 mm. 
Second stage. — Head shining black, labrum whitish; width 1.45 mm. 
Body orange color, with two transverse black bands on each segment, 
indented toward the center, corresponding to the bases of the processes. 
Processes cylindrical, with enlarged conical base, and bearing at the tip 
six radiating stiff spines and one vertical one with enlarged base. 
There are two vertical spines on the single dorsal process of joint 12. 
The spines are as long as the processes, not longer. Thoracic feet, 
abdomhial ones outwardly, and processes with tlie spines all shining black. 
Spiracles white witli black edge. There is no cervical shield; but an 
anal plate is present and a plate at base of each anal foot. All the 
processes are alike, row 3 about two thirds as long as rows 1 and 2, row 
4 short, conical, with only the apical spine present. 
Third stage. — Head light yellow with a large black patch on each side 
of the clypeus and one over the ocelli; labrum, antennae, and palpi black; 
a few pale hairs; width 2.15 mm. Body pale greenish yellow, darker 
around the bases of the processes. A dorsal row of black dots, two on 
each segment. A stigmatal row, one on each segment, posterior to the 
spiracles ; a few ventral black spots. Thoracic feet black, abdominal 
feet yellow ; spiracles white with a narrow black edge. Processes of 
uniform length, thick, blue-black; their spines rather shorter than the 
stem. The processes of row 1 on joints 3-5 are slightly thicker than the 
others. 
Fourth stage. — Head as before; width 3.4 mm. Body bluisli green, the 
black dots as before, but reduced. Thoracic feet with the basal joint 
yellow , the terminal joints black. Abdominal feet yellow Avith blackish 
claspers. Spines not more than half or two thirds as long as the stem. 
Processes thick, forming slight enlargements at the bases of the spines, 
all shining black except row 1 on joints 3-5 and 12, which are spotted 
with yellow on the shaft. Spiracles as before. 
Fifth stage. — Head I'ound, full, median suture well marked; yellowish 
green, not shining, with a small black spot on ocelli and a narrow streak 
each side of the clypeus; mouth whitish ; base of antennae and labrum 
pale blue; width 5 mm. Body large, thick, cylindrical, the incisures well 
marked ; slightly enlarged at the thoracic segments and joint 12 ; a large 
square cervical shield and three triangular anal plates, yellowish green. 
Body bluish green with a gray tint with minute black specks, some of 
which bear setae. Thoracic feet yellowish green with black tips ; abdom- 
inal ones yellowish green outwardly, bluish at tip with short black hairs.
