This has been reared again at Pusa from larve found on 21st August 
1919, feeding on leaves and top-shoots of sinhora (Streblus asper ?). The larva 
(Plate LXIV, fig. 1a) is very active, jumping at the least touch ; it is about 
10mm. long and 1 mm. across the middle, tapering slightly posteriorly ; general 
colour whitish-blue with numerous black spots ; head rather flattened, yellowish- 
brown. 
Pupation takes place in a double cocoon which is usually spun on a leaf, 
the outer cocoon being of thin texture whilst the inner one, in which the pupa 
rests, is stiff. Pupation occurs about two days after commencing to spin up 
and the moth emerges after another six days. The pupa (Plate LXIV, fig. 1b) 
is about 5°5 mm. long and 1:75 mm. across the thorax, brown-yellow. The 
moths (Plate LXIV, fig. 1c) from these larvee emerged between 3rd and 6th 
September. (Pusa Insectary Cage-slip 1915.) 
CHOREUTIS BJERKANDRELLA, THNB. (ante, page 128.) (PLATE LXIV, FIG. 2.) 
This has also been reared at Pusa from larvee found on 22nd October 1919, 
webbing the top-leaves of mundi (Spheranthus indicus), living hidden inside 
the webbed-up leaves and nibbling their surfaces. 
The full-grown larva (Plate LXIV, fig. 2a) was described as about 7 mm. 
long and slightly more than 1 mm. broad across the middle of the body which 
tapers slightly towards either end, skin glossy, soft and transparent, pale 
yellow, showing a slight green tinge when food is taken ; head rather glossy ; 
dorsal vessel faintly visible ; short, yellow hairs arising from black points ; 
spiracles small, round, with a brown rim; five pairs of equally-developed, 
slender, rod-like prolegs. 
Pupation takes place on the plant im thin white silken cocoons formed 
amongst the leaves. The pupa (Plate LXIV, fig. 2b) is about 45 mm. 
‘long and 1:3 mm. across the thoracic region, yellow-brown ; -capital 
extremity blunt; anal extremity tapering; anal segment dorsally with 
an anteriorly-curved horn-like spine. When disturbed, the pupa does not 
wriggle but moves the anal extremity rapidly up and down. The pupal 
period is about five days. Moths (Plate LXIV, fig. 2c) emerged from these 
larve between 28th October and 19th November. (Pusa Insectary Cage-slip 
1938.)
