This polynomial species, originally described('!) from specimens bred 
from larve in spun-up shoots of Cajanus indicus at Surat, has since been 
recorded* from North Coorg(7), Southern India(®) and Pusa(®) and it pro- 
bably occurs throughout the Plains of India. We have it from Pusa, Surat 
and Coimbatore. Hitherto it has only been noticed to attack Cajanus indicus, 
of which it is a minor pest, the larva rolling and webbing together the top- 
leaves of its foodplant and also eating into flower-buds and boring into pods 
and devouring the seeds. At Pusa this species is active from March to May 
and again from August to October, hibernating in the larval state. The folluw- 
ing is a summary of the life-history as noted at Pusa :— 
The egg is elongate with rounded ends, about 0°5 mm. long and 0°25 mm. 
in diameter. When laid it is of a creamy white with a greenish tinge but 
later on turns yellow and small reddish patches, usually forming two inter- 
rupted reddish longitudinal markings, appear on its surface. Eggs are laid 
at night and singly ; when several are laid close to one another they are usually 
placed in a row. They may be laid on any part of the foodplant—on the 
upper or lower surfaces of leaves, on petioles of leaves, or on the stem—but 
a groove or depression is always preferred as a suitable place for oviposition ; 
thus, on the upper surfaces of leaves most eggs will be found on a midrib or 
vein whilst on lower surfaces of leaves they will be found placed beside a 
midrib or vein, and the grooves of petioles or peduncles are very favourite 
places. A female moth, which emerged on 5th October, laid in confinement 
*Tt has also been recorded from other localities (e.y., Nagpur and Raipur) but it is doubtful 
how far som® of these records really refer to Z. critica.
