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 ^'^^'^^- 



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, II 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 i 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. A 

 pair of pointed, slender, pale brown, black -tipped patches of detachable 

 spines above the subdorsal horn of joint 13; caltrope patches pale
