132 LIFE-HISTORIES OF HYPONOMEUTID 
SOYTHRIDIDA, 
The early stages of no Indian species appear to have been observed: 
The larvee of some of the European species are leaf-miners when young, some- 
times gregariously, but when older spin leaves together and feed on the cuticle. 
(See Stainton, Nat. Hist. Tin., XII, 70, t. 3.) 
ELACHISTIDA. 
Only a few Indian species of Elachistidee have been described and the 
life-history of none is known. In Europe the larvee mine the leaves of 
Graminee and Cyperacee chiefly. (See Stainton, Nat. Hist. Tineina, Vol. TI.)

Prays nephelomima, Meyr., Pr. Linn. Soe. N. 8. W., 1907, 76(!9). 
A widely-distributed species recorded from the South of France, Corsica (?*) 
Sicily(? + 8), the Canary Islands, New South Wales(!°) and the Philippines(’ °). 
Within our limits known to occur in Ceylon (Colombo, Maskeliya and Madul- 
sima)(®), in North Coorg(®), and at Pusa(®) and will doubtless be found to 
_be widely distributed in India. We have specimens from Maskeliya and Pusa. 
The larva has been recorded as a serious pest of the orange and other 
species of Citrus, feeding in the shoots and eating into all the flower organs, 
whilst in the Philippines the larva has been found to make a gall in the rind 
of orange fruits. 
Eggs are deposited apparently upon the calices or peduncle of the flower, 
usually just prior to opening, the young larve boring through into the interior 
of the flower, which is destroyed ; pupation usually within the flower, but 
also in protected places on the leaves or forks of the twigs and branches(§). - -
