brownish. When full-grown the larva leaves the mine and forms a circular 
flat cocoon on a depressed corner (e.g., by the side of a raised leaf-vein or on 
the upper side of the midrib) and pupates in it. The larve are heavily 
parasitized by a small black Hymenopterous fly. The moths are on the wing 
at Pusa throughout May. (Insectary Cage-slip 1572.)

T. lb (Ne Described from Calcutta from larvee mining the under side of the leaves 
hat of Terminalia Catappa. The larva was described by Atkinson as “ small, 
but very active. It detaches the lower cuticle over a wide extent of surface ; 
it devours both layers of parenchyma, not continuously, but in very small 
oblong patches, so that the upper surface of the mined portion of the leaf 
which is blotched with purple, appears thickly sprinkled over with white dots. 
The lower cuticle, which is detached, is very thin and transparent, and, by 
shghtly contracting, it curves the upper portion of the leaf, so as to form a 
very spacious vaulted chamber for the little resident. On attaining its full 
growth, the larva leaves the mine and spins in some convenient corner a 
compact white cocoon ”’('),

Larva mining leaves of mango at Pusa in August 1908. Also recorded 
from Rajshahi in March 1911 and Coimbatore (31st May 1913). 
Larve were found at Pusa mining leaves of chichira (Achyranthes aspera) 
on 11th September 1915, as many as nine or ten larve in one leaf. The 
epidermal tissue of both surfaces is attacked and mined into large irregular 
patches measuring as much as 31 mm. in diameter (average about 22 mm.) ; 
the upper surface, where attacked, turns yellow and then brown and the 
lower surface to brownish-green. 
The larva is about 3-5 mm. long and 0°75 mm. broad, yellow, segments 
distinct ; head short with brown cheeks, clypeus and mandibles ; hairs on
