524 ENTOMOLOGICAL NEWS. [September, 



mature larva. Cold bluish green except in an area which is 

 opaque yellowish green, covering the dorsal space from joint 5 

 posteriorly to joint 12, and laterally from 3 posteriori y to 12, 

 continuous, except for the horns and depressed spaces. Seg- 

 mental incisures well marked; depressed spaces (i) and (4) 

 pale, strongly bordered with black. Joint 2 smooth, slightly 

 purplish ; cervical shield black. Skin rather densely covered 

 with fine spinules, mostly sharp pointed. On the yellow green 

 all are colorless, but on the blue green they are black, especi- 

 ally dorsally on joints 3 to 5. Only a few black spinules on 

 the subventral blue green and these are above the bases of the 

 lateral horns. A distinct ring of black spinules around the base 

 of the subdorsal horn of joint 1 1 and less on joints 4 and 5. The 

 horns lengthen during the stage, are distinctly purple ( except the 

 subdorsals of 6 to 10) and a purple shade appears centrally on 

 the dorsum of joints 3-4, in the blue green. Length 6 to 8. 8 mm. 



Stage VII. No essential change except the presence of a 

 3'ellow border to the dorsal green and the caltropes. Shape as 

 before, the horns all a little shorter and thicker at first. Sub- 

 dorsals of joints 6 to 10 present as before, all several spined. 

 Joint 2 pinkish, setose in front, spinulose on the sides ; cervical 

 shield deep black . Dorsal yellow green obscurely yellow on the 

 edge all around, including a ring about the subdorsal horn of 

 joint ii ; without this a fine line of black spinules. Horns 

 pinkish except the subdorsals of joints 5 and 1 1 which are 

 cold blue green and those of joints 6 to 10, which are nearly 

 colorless. That of joint 6 has only two or three spines and is 

 sessile. Spines salmon-colored with black tips. Depressed 

 space (i) and (4) pale, narrowly black edged; (6) indicated 

 by a black dot. Patches of caltropes on the tips of the lateral 

 horns of joints 6 to 12 and also on the lateral horn of joint 4 

 and even a few 7 on top of the subdorsal horns of 5, 1 1 and 12 ; 

 a distinct patch on the subdorsal of 13. Skin spinules black 

 in the blue-green parts as before. Dorsum of joints 3-4 shaded 

 with purplish as before. Length 8.8 to 11 mm. 



Stage VIII. As before, but the subdorsal horns of joints 4 

 and 12 as well as those of 5 and n are blue green, the others 

 still pinkish ; there is a narrow dark green edge to the blanket 

 patch outside of the yellow and small imperfect patches of de-
