128 LIFE-HISTORIES OF BLASTOBASIDA 
The moths strut about jerkily with the hmdwings carried nearly at a 
right angle with the forewings, so that the wings form a sort of cone when 
seen from behind the insect. The eyes are pale green. This attitude is 
characteristic of other species of this genus.

A cosmopolitan species known from Kurope, North, Central and South 
America, North and South Africa, Western Asia, India, Australia and New 
Zealand. 
Larva described by Spuler ; on leaves of Carlina, Inula, Carduus, ete.(?). 
Larva green, yellower laterally ; spots black ; head brown ; on Carduus, 
Inula, Eryngium, ete.(*). 
Larvee were collected at Pusa on kukronda (¢ Blumea balsamifera) on 14th 
January 1910, the moths emerging between 14th January and 5th February. 
The larva was described as about 7 to 8 mm. long, cylindrical, shghtly tapering 
towards extremities, uniform green ; head yellowish-green ; hairs arising from 
small black points, making the larva look minutely spotted under a lens ; 
five pairs of equally developed prolegs. The larva rolls a single leaf, or only 
the apical portion, or binds one leaf over another or binds together the top 
leaves ; it lives concealed and eats only the epidermis or the epidermis along 
with the mesophyll substance of the leaf, leaving one epidermal layer entire, 
so that when the leaf is unrolled the portion eaten appears as a transparent 
brown spot. Pupation takes place in concealment also in a cocoon of pure 
white silk lining a rolled-up leaf. The pupa is about 4 to 5 mm. long, cylin- 
drical, tapering posteriorly, dark-coloured, the dorsal side of the anal segment 
produced into a short thick recurved hook-like process. The pupa wriggles 
out of the cocoon before the moth emerges. (Pusa Insectary Cage-slip 816.) 
The moth is plentiful at Pusa in February and March and occurs less 
commonly in April and June. We have it from Pusa, Parachinar and Simla.
