Common throughout India and Ceylon and widely distributed from 
Australia(?), New Guinea(?) and Borneo(?) to Mauritius(® 4), the Seychelles(4) 
and British Guiana(®). 
Mr. Meyrick has suggested that the larva is “ probably attached to some 
plant of ‘cultivation (3). It may be noted that Cosmopteryx pallifasciella, 
Snell. (Tajds. v. Ent., XL, 138-139, t. 6, f. 1 (1897)), described from Java, 
mines in sugarcane in its larval stage. 
C. mimetis has been bred at Pusa from larvee found mining leaves of 
motha grass (Cyperus rotundus). The larva mines the leaf either in its middle 
or in its apical part, the mine running along and on either side of the mid-rib. 
From larve collected on 15th September 1916, thirty-eight moths emerged 
from 25th September to 8th December, and eight Hymenopterous parasites 
were also reared. 
The larva is about 3 mm. long, tapering posteriorly, uniform light yellow ; 
head flattened, narrower than prothorax, the lobes much elongated posteriorly ; 
prothorax broader than followmg segments ; legs and prolegs small. (Pusa 
Insectary Cage-shps 1472, 1521.) 
We have C. mimetis from Peshawar, Pusa and Bassein Fort. It is 
probably widely distributed throughout the Plains of India.

Cosmopteryx bambuse, Meyr., Ent. Mo. Mag., LIII, 258 (Nov. 1917)(?). 
“ Pusa, bred in October from larvee mining blotches in leaves of bamboo 
(Fletcher). ... - A pupa-case sent (very little discomposed by the emergence 
of imago through a small slit) shows only two abdominal segments free, the 
rest fixed, wing-cases reaching to end of penultimate segment ”’(}). 
Larve were found at Pusa on 3rd January 1916 and 21st September 
1916, mining blotches in bamboo leaves. The larva mines the leaf, forming 
a sharply-defined yellowish-white patch in the middle of the leaf-blade and 
usually on one side of the mid-rib. There may be two or even three larve 
in one leaf, forming mines on either side of the mid-rib or at different places 
on the same side of it, The mine commences as a narrow strip which gradually
