tint from the blood, the effect increased by some bright green pigment, 
not evenly distributed. In the dorsal space it is absent between the 
large horns, being therefore especially noticeable in two square patches 
on joints 6—7 and 9—10. Between these patches and the yellow sub¬ 
dorsal line is a slight space which will become the waved dark green 
line ; but as yet it is not indicated. Yellow subdorsal line broad, ir¬ 
regular. In the lateral space the green pigment is situated in a band 
below the subdorsal line, separated from it by a space which is already 
defined faintly as a dark green line. The green pigment encloses the 
upper intersegmental whitish dots, but below this the body is only green 
from the blood. A narrow distinct whitish dorsal line. Horns green¬ 
ish except the six red pairs. The short horns are as well spined as the 
long ones, in proportion. Skin finely watery granular. Length 5.3 to 
7 mm. 
Stage VI. —Elliptical, flattened, highest through joint 5, though 
not conspicuously so. Green, dorsum flat, not tapering much at the 
ends, yellowish green, a narrow yellow dorsal line and a dark clear 
green waved line above the subdorsal band ; intersegmental glandular 
dots whitish ; the green band is most pronounced on joints 6 to 10, giv¬ 
ing the appearance of a central darker green patch, but this disappears 
under a lens. Subdorsal line rather broad, yellow, extending from 
joints 3 to 13. Horns short and slender, the longest ones on joints 3, 
4, 5, 8, 11 and 12 bright red, the others moderate, colorless. Lateral 
space nearly colorless, shaded with light green on the lateral ridges be¬ 
tween the depressed spaces, two rows of white glandular dots in the 
broad intersegmental hollows. Lateral horns rather long, alike, pale 
green, those on joints 3 and 4 tipped with brownish. A broken, pale 
lateral line. Subventral space contracted, colorless. Head green, jaws 
brown, ocelli black ] width 1 mm. Spines colorless \ skin with fine 
clear granules. Length of larva 7 to 10 mm. 
Stage VII. —Essentially the same. There are now present a series 
of caltrope patches toward the tips of the lateral horns on joints 6 to 
12, and on the subdorsal horn on joint 13. Width of head 1.6 mm. 
Length of larva 10 to 14.5 mm. The dark green lines adjoining the 
subdorsal and lateral ridges vary in distinctness in different larvae, grad¬ 
ually becoming more distinct as the larvae grow. 
Stage VIII —As before. The red horns vary in color in differ¬ 
ent examples, some being faintly colored or even greenish, 
pair of pointed, slender, pale brown, black-tipped patches of detachable 
spines above the subdorsal horn of joint 13; caltrope patches pale
