EPIMARPTIS PHILOCOMA, MEYR. |<< “420 ¢-4!5 ) 
Epimarptis philocoma, Meyr., B. J., XXII, 776 (1914)(!), Exot. Micr., II, 69 
(1917)(2). 
Described from Karwar, North Kanara, from a single specimen reared 
in September(!). Since recorded from the Khasi Hills(?). 
“ Larva reddish (including head) ; lives in a white web on midrib of an 
unknown plant, the web ‘being on both sides of the leaf, kept off the surface 
by little pillars of excrement ; the webs on either surface of the leaf are con- 
nected by holes through the leaf itself, and the larva uses these alternative 
abodes as-a means of escaping observation, dodging through the holes with 
much agility ; cocoon separate, close to midrib, oval, resembling a_ bird- 
dropping *("). 
IDIOGLOSSA TRIACMA, MEYR. (PLATE XLVI.) 
Idioglossa triacma, Meyr., Exot. Micr., I, 77-78 (1913)(!). 
Originally described from the Khasi Hills, this species has been reared 
at Pusa from larvae: found on 14th November 1916 nibbling leaves of Commelina 
bengalensis (Commelinaceze). The larva forms a tunnel across the midrib 
of the leaf and through this tunnel it has access to both halves of the blade 
of the leaf. It feeds on one epidermis and tissue of the leaf, leaving the other 
epidermis entire and, over the part it feeds on, it spins a white silken webbirg.
