ANTISPILA ARGOSTOMA, MEYR. (PLATE XXVIL.) 
Antispila argostoma, Meyr., Exot. Micr., II, 8 (Oct. 1916)(‘). 
Bred at Pusa “in August’ from larva mining blotch in leaf of Vitis 
trifolia (Fletcher); cocoon sent is oval, similar in construction to preceding 
[aristarcha] but larger, greyish-ochreous, spinous filaments only 1-14 length of 
cocoon ”’(!). 
This species is common at Pusa during the Rains (July-September), 
and has been bred from larve mining leaves of Vitis trifolia, Although it 
may be reared in numbers, the adult insect has never been noticed under 
natural conditions. The larva mines a portion of the leaf, leaving intact the 
two membranous epidermal layers. It commences the mine from any place 
on the surface. While the larva is young it causes a narrow zigzag yellowish- 
white line as it mines on and in the middle of this line a streak of black excre- 
ment is left along its whole length. The mine becomes gradually broader 
and then develops rather abruptly into a large yellowish-white blotch and 
the quantity of excrement is also large, appearing like a large black patch 
in the middle of the mine. When the larva is full-grown, it lines an oval 
portion of the mine near the edge with brown silk and converts it into a flat 
. 9
