sharp, all rounded ; subdorsal processes fleshy, hornlike, those on joints 

 3, 4, 5, 1 1 and 12 long, densely spined, on joints 7, 8 and 9 very short, 

 consisting of a wart with three or four spines, rudimentary on joints 6 

 and 10, short on joint 13. Lateral row on joints 3, 4, 6 to 12, mode- 

 rate, spined, those on joints 3 and 4 slightly larger than the others ; on 

 joint 13 a few spines. Subventral edge scarcely ridged, setiferous. 

 Skin closely covered with minute spinulose granules, close set, without 

 tubercular bases, a little sunken in places corresponding to the usual de- 

 pressed areas, especially in the dorsal intersegmental ones, but obscurely, 

 and the areas are scarcely distinguishable. The color is subject to some 

 variation in different examples. When well developed, the color is light 

 green, the horns translucent whitish, except the subdorsal on joint 4 

 which has a faint vinous tinge, on joint 5 dark purplish vinous, and on 

 joint II pale purple. A waved black subdorsal line, the pair connected 

 by shaded streaks over the dorsum on joints 3, 4, 5 and 11, about two 

 on each segment, leaving square or rounded patches of the ground color 

 between the pairs of horns, that on joint 5 distinctly round. Subdorsal 

 band broken on joints 6 to 10 (Plate I, fig. 2) and on joints 7 to 9 

 bordered above by a white band, the dorsal space here filled in with a 

 blackish shade, which forms an elongated patch. Posterior end of the 

 body and lateral region immaculate. Head green, shaded with brownish 

 below, eyes black ; width .5 mm. Length of the larva 2 to 3 mm. 



S/a^e IV. — Essentially as before, the markings better defined. 

 Dorsal intersegmental depressions small, paired, or single next to the 

 large horns, at the base of which is indicated a paired addorsal seg- 

 mental row. Horns of both rows on joints 3 and 4 pale flesh pink, the 

 subdorsal on joints 5 and 11 purple, on joint 12 yellowish, the rest 

 nearly colorless. Dorsal and lateral region of joints 3 to 5 and dorsal 

 region of joint 1 1 purple, except the small paired greenish impressed 

 spots and an unpaired median oval yellow one on joints 5 and 11. 

 Dorsal patch on joints 7 to 9 blackish, bordered with white at the sides 

 and below by a waved line. This white and black marking is repeated 

 around the rudimental subdorsal tubercle on joints 6 and 10, closely 

 approximated to the adjacent large horn. Ground color of the dorsum 

 green, replaced by yellow on joints 5, 6, 10 and 11; lateral region 

 whitish. An elliptical white spot subdorsally between the horns of 

 joints II and 12. The spines on the horns and skin spinules essentially 

 as in the mature larva, the latter passing on to the horns where they be- 

 come elongated into short spines. Width of the head .7 mm. (calcu- 

 lated .72 mm.). Length of the larva 3 to 5.5 mm.
