Larva. —Feeds on Zizyphus xylopyrus and Z. loranthus , only on the parenchyma 
of the leaf, is of the usual woodlouse form, slightly flattened; head concealed in the 
second segment, surface more or less rough ; a fringe of long white bristles all round, 
with an erected ridge of similar bristles along the back from the 2nd segment, those 
on the 3rd to 7th segments, and the last two, much longer than the others, those on 
the 2nd segment very few, short and black. It has a conspicuous gland on the 12 th 
segment, and is attended by a small species of ant of the genus Cremastogaster. Its 
colour is pale green; the dorsal portion of the 2nd, 4th, 5th, 6th and last two segments 
being park brown, while the centre segments are almost yellow with a darker dorsal 
line. 
Pupa. —Of the usual Castalius form, but narrow and slightly flattened. It is 
intensely glossy, as if covered with gum. It varies in colour, being sometimes black, 
at others green, with inconstant black markings. 
Habitat. —Sikkim, Orissa, Southern India.

Watson from the Chin Hills; we have received many examples from the Khasia Hills ; 
it is in the B. M. also from the Nil girls and 1ST. Kanara.
