_ ACROCERCOPS BIFRENIS, MEYR. (ante, page 157.) 
Bred at Khanapur, Belgaum, between 21st and 25th February 1915, 
from larve found very plentifully in leaves of more than one unidentified 
food-plant ; one of these food-plants was described as having the leaves alternate, 
simple, smooth, acuminate, with opposite veins 4 to 6or8. The larval blotches 
were irregularly shaped, becoming confluent with other blotches in the same 
leaf, the whole of which is eventually left covered with the silvery cuticle only, 
the leaf underneath being discoloured with dry excrement, which is chiefly 
gathered around the edge of the blotches. Each blotch has an irregularly 
roundish tear in the cuticle covering it whilst still imhabited by the larva. 
The young larva is bright red, much tapering towards the tail ; when full-fed 
it is bright crimson, cylindrical. The orange-coloured pupa is found in an orange 
cocoon formed on the surface of the leaf. The pupal period is about seven to 
eleven days in February. The imago quivers on its legs like A. vanula.

ACROCERCOPS CRYSTALLOPA, MEYR. (ante, page 157.) 
Bred in July 1913 and also in 1915 at Karwar from larve found on Meme- 
cylon edule and M. amplexicaule in regular oval or sub-circular blister-like 
blotches formed under the upper cuticle of the leaf by continuously mining 
around the edge of the blotch. The larva has a very large dilated head, the 
body cylindrical with lateral prominences from which protrude single rather 
long hairs. The pupa is found inside the larval blotch and protrudes through 
the leaf-cuticle on emergence. The moth sits almost erect on its tail with the 
long antenne held outwards and (relatively to the body) downwards, vibrating 
so rapidly as to be nearly invisible except towards the base. (Mazwell.) 
ACROCERCOPS DIATONICA, MEYR. (ante, page 158.) 
Bred in North Kanara from larve, sometimes found singly but often in 
numbers, under the upper cuticle of an unidentified herbaceous plant. The 
cuticle forms a tight blister over the whole surface of the leaf, and inside this 
blister the larva lives and feeds on the leaf which it ultimately clears, leaving 
only the tip and the cuticle. Pupation takes place in an oval cocoon which
