Description. 
Larva.—The general appearance of the larva is black above 
and yellow or green beneath. The dorsal colour, however, of 
the last 11 segments varies from black to a dark purple-grey. 
A broad reddish or flesh-coloured stripe runs down the median 
dorsal surface, bordered on either side by a narrow, white line. 
Another lateral white line is usually present on each side just 
above the junction of the upper black with the lower yellow 
colour. The head and first segment are black. On the dorsal 
surtace of the last segment but one there is a white transverse 
matk which is very constant, being invariably present in the 
very mumerous specimens examined. Body covered with 
scattered hairs, The larva tapers towards both ends, Length 
1 to 14 inches.

stripe or yellow ventral colouring. It may be, however, that the 
young dark-coloured larvze seen are those of the black variety 
of Hyblza described below. 
The larva spins a rough, loose, silken cocoon to pupate in. 
Pupa.—A bright chestnut brown in colour with a yellowish 
tinge. Darkens slightly after a day or two, but the colouring
