Described from eee in North Kanara(!), where it was bred in July 
from larva mining a compact blotch in leaves of mango (Mangifera indica) ; 
pupa in a detached oval brownish-yellow cocoon on surface of leaf (Mazxwell)(*). 
Reared at Pusa in September 1907 and again in August 1908 from larve 
mining mango leaves. Also taken at Bankipur in October 1911(?). We have 
it also from Pusa in September to November 1916, from Saidapet in January 
1907 and from Coimbatore in December 1914 and March 1915, in all cases 
_reared from larvee mining mango leaves. 
The larva mines under the epidermis on the upper surface of tender mango 
leaves, causing large round or roundish blisters which are greyish-white in 
colour. The larva is about 5 mm. long and about 0°7 mm. across the thoracic 
region, cylindrical (or almost so), tapering posteriorly, segments well-defined 
and rather proniment laterally, pale greenish-yellow, the dark contents of 
alimentary canal partially visible through the body ; head brownish-yellow, 
shiny, smaller than prothorax, which has a faint shiny yellowish shield ; a 
faint whitish tracheal line along the spiracular region ; primary hairs short 3 
legs and prolegs concolorous with body ; prolegs on third, fourth, fifth abdo- 
minal and on anal segment. From leaves collected on 25th September moths 
emerged from 4th October to 1st December 1916, and from leaves collected 
on 2nd November 1916 moths emerged on 15th and 16th November. (Insec-
