56 LIFE-HISTORIES OF EUCOSMIDA 
Pupation takes place within a white silken cocoon formed amongst spun- 
up top-leaves or between super-imposed blades of an older leaf, amongst 
spun-up flowers, or near the mouth of the tunnel in a bored pod. The pupal 
period is from five to eight days at the end of September. Before emergence, 
the pupa wriggles out through one end of the cocoon to some extent. 
The pupa is about 6 to 75 mm. long and 1:5 to 2 mm. broad, cylindrical, 
brown, anal extremity rather obtuse ; abdominal segments with a transverse 
row of short black spines extending across dorsum from spiracle and another 
similar but faintly-developed row across posterior portion of segments ; anal 
segment dorsally armed with six upturned black spines. (Pusa Insectary 
Cage-slips 517, 611, 1644, 1689, and 1694.) 
The coloration of the imago is very variable, some of the more common 
forms being shown in the figures. 
EUCOSMA BALANOPTYCHA, MEYR. 
Eucosma balanoptycha, Meyr., Rec. Ind. Mus., V, 218(!), Exot. Micr., II, 18(?). 
Originally described from Maskeliya, Puri and Konkan(!). Since reared 
at Coimbatore on leaves of Pongamia glabra (Leguminose)(?) in October 
1914. We have it from Coimbatore (larva on Pongamia leaves) and from 
Ahmedabad (reared from larva eating galls on Pongamia glabra leaf). 
EUCOSMA CLEPSIDOMA, MEYR. 
‘Eucosma clepsidoma, Meyr., Exot. Micr., II, 18 (Oct. 1916)(!). 
“Bred at Coimbatore in April from galls on an unidentified plant 
(Fletcher) (').

EUCOSMA CONCILIATA, MEYR. MS! (PLATE X, FIG. 2.) 
Larve were found at Pusa on 20th March and 20th April 1917, feeding 
on the flowers of palas (Butea frondosa). Some of the petals of the flowers, 
va., the wings and the keel, are joined towards their bases and the larve 
are usually found boring the thick conjoined parts, and they pupate in these 
parts in a sort of silken cocoon. The larva, when full-grown, is about 11 mm. 
long and 1°5 mm. broad across mid-body, slightly flattened, tapering towards 
either extremity, uniform pale yellow, the dorsal vessel showing through the 
skin and the primary tubercles looking like small brown points (under a lens) ; 
head smaller than prothorax, rather dark brown, shiny ; prothoracic shield 
medially divided, concolorous with head; five pairs of equally developed 
prolegs. The pupal period in April is about six days. (Pusa Insectary Cage- 
slip 1536.)
