GRACILLARIADA. 
LITHOCOLLETIS VIRGULATA, MEYR. (ante, page 138.) 
Bred [at Karwar] in January and May 1916 from larvee found in a more . 
or less regular oval or roundish blotch, measuring about 15 by 10 mm., formed 
on the upper surface of a leaf of Butea frondosa. The cuticle over the blotch 
becomes tightly stretched and white, often puckering the leaf below it; a 
small discoloured oval patch is often visible on the white stretched cuticle, 
probably representing the early location of the larva. Pupation takes within 
the blotch and in the case of one specimen the pupa was observed to be tightly 
enclosed in a fine white spindle-shaped cocoon resting on the leaf-surface, 
but in other cases it seemed to be in a fine, light-spun web. The pupa is pro- 
truded on emergence, puncturing the cuticle of the blotch by means of a sharp 
diamond-shaped rostrum on its head ; the position of the pupa on emergence 
is supine. One specimen was noticed to emerge at about 10 a.m. The moth 
sits with the head depressed, touching the resting surface, and the tail elevated ; 
this was observed in every specimen bred. (Mawell.) 
Larve were collected at Pusa on 9th June 1919, mining blotches in the 
upper surface of leaves of Pongamia glabra. The mines were of various 
shapes and sizes, one being almost oval and measuring 10 by 9 mm., another 
being elongated and measuring 19 by 11 mm. Pupation took place inside the 
larval mines and the pupe pierced through the membranous covering of the mine 
and wriggled out to some extent before emergence of the moths, the empty 
pupa-cases being left sticking out of the mines. Moths emerged on 16th June.

LITHOCOLLETIS INCURVATA, MEYR. (ante, page 141.) 
Bred at Karwar in August 1913 from larva mining leaf of “ karvd” (Strobi- 
lanthes), forming a small blotch fillmg the space between two veins of the leaf, 
apparently between the two cuticles. The blotch is dilated, concealing its 
inhabitant. Pupation takes place internally, at one end of the larval blotch. 
The imago rests with its head down and tail elevated. (Maavwell.) 
ACROCERCOPS ORDINATELLA, MEYR. (ante, page 146.) 
Bred in North Kanara in July and August 1913 from larve on Alseodaphne 
semecarpifolia and probably other species of Lauracew. The egg is almost 
invariably laid near the mid-rib of the leaf and the young larva proceeds by a 
fine gallery to the blotch which it inhabits for the rest of its life. The blotch 
is rather regular in shape, below the upper cuticle of the leaf which has a tightly 
stretched appearance, the excrement being gathered at the sides of the blotch.
