blackish. V-mark distinct, pale yellow, with no enclosed dot. There is a 
velvety brown-black subdorsal shade, irregularly touching the region of 
tubercles 1 and 2, beginning in a narrow line on the side of the process on 
joint 5, becoming more and more pronounced posteriorly till it fills in all 
the space around the V-mark. Joint 12 is again ligliter, the brown shade 
forming a pair of narrow lines on the anterior side of the hump, but 
obtaining again on joint 13. Trace of a lateral line, but broken and diffuse. 
A distinct substigmatal line. Abdominal feet on joints 7-10 pale, marked 
with reddish mottlings, tlie claspers vinous. An oblique brown line runs 
from base of the horn on joint 5 to the anterior side of tlie foot on joint 7. 
and another, subventrally, from below the hump on joint 12 to tlie posterior 
side of the foot on joint 10 and, continued back subventrally, ends on the 
anal foot. Setae short, rather dark. 
Fifth stage. — Much as before, but tlie process on joint 4 is pronounced, 
leaning backward to touch the horn on joint 5 ; width of head 3.5 mm.

reticulations. Horn 6 mm. long, tapering, the distal half slender. When 
full grown the larva becomes paler throughout, though different individuals 
vary in shade. Feeds solitary on the edge of a leaf.
