The above statement that the larval food is probably the bark of the tree 
is not correct ; the larva feeds on the leaves and apparently only hides under 
the bark in the intervals of feeding. Pupation may take place under the 
bark or between two rolled or superimposed leaves, the cocoon lining the 
leaves being much larger than seems requisite to contain the enclosed pupa. 
One individual which pupated amongst leaves on 23rd February 1914, emerged 
as a moth on 7th March 1914; but the period of emergence is a prolonged 
one and specimens have been bred out between 30th April and 2nd July from 
larve collected at the end of March and between 29th May and 20th July from 
larve collected in the latter half of May, so that it appears that the broods are 
irregular and overlap one another. 
As noted above the larve are attacked by a Bombylid fly whose maggots 
consume the entire’ contents of their host after the latter has pupated and 
pupate inside its empty pupa-case. These Bompbylid flies have been bred 
out between 15th and 24th April 1916. 
The larve are also attacked by a Hymenopterous parasite which was 
reared between 24th March and 2nd April 1914. The parasitic grubs emerged 
from the body of their larval host and formed cocoons within rolled leaves 
but apart from the dead body of the host. | 
The full-grown larva is about 10 mm. long, subcylindrical, pale yellow ; 
head brown, flattened, small; legs and prolegs normal, unicolorous with 
body. 
The pupa is about 5 mm. long, cylindrical, slightly tapering towards 
either extremity, anal extremity blunted, reddish brown ; abdominal segments 
dorsally with transverse rows of minute spines; anal segment with four 
cremastral hooks. (Pusa Insectary Cage-slips 336, 1080, 1056, 1891; C.S.

Larva in stems of Crotalaria(!). Widely distributed throughout India 
and Ceylon. Also recorded from Transvaal(?). 
“T,. tricentra, Meyr., is described from the Deccan, the larva tunnelling 
in the shoots of Sann-hemp (Crotalaria juncea)(3).” 
The Pusa collection contains specimens from Surat, Bassein Fort (Bombay) 
and Yercaud, and from Coimbatore (reared from cowpea pods).
