[Vol. IV. 
sharp, all rounded; subdorsal processes fleshy, hornlike, those on joints 
3, 4, 5, n 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 11 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. 
Stage 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 11 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 11 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.
