The following species formerly recorded as Indian are omitted. 



Debos iratus, Swinh., C. & S. no. 277, is probably a Tinea. 

 Dioptis perdica, Cram., C. & S. no. 350, Geometer from Aniboina. 

 Codane leucomelas, Moore, C. & S. no. 442, is from Siam. 

 The genus Chatamla, Moore, C. & S. nos. 426, 427, 428, belongs 



to the Epiplemidce. 



Atossa nelcinna, Moore, C. & S. no. 457, belongs to the Uraniidce. 

 C. & S. nos. 351-359 form the family Epicopiidce.

Family PSYCHID^. 



The larvae feed in a case composed of a 

 silk lining with twigs, grass, and bits of 

 leaves or vegetable matter attached to the 

 outside. The pupa is formed inside the 

 larva-case. The perfect female also lives in 

 the case and is devoid of legs,wings, antennae, 

 and mouth-parts (being thus merely a 

 vermiform egg-sac) ; the three thoracic 

 segments bear corneous dorsal plates. In 

 the genera Bijugis and Fumea, however, 

 the antennae are articulated. Copulation 

 takes place by the male alighting on the 

 case and inserting his protrusible abdomen 

 between the case and the ventral surface of 

 the female ; in Fwnea the female comes out 

 of the case for copulation. Parthenogenesis 

 is known to be the normal method of re- 

 production in Apterona helix, but it is ex- 

 tremely doubtful if it often occurs in other 

 species of Psycliidce. 



The males have the antennae bipectinated 

 (or serrate in the genus Apterona) ; the 

 proboscis, palpi, and ocelli absent. Fore wing 

 with two internal nervures, 1 b being forked 

 at the base ; a single or forked veinlet in the 

 cell. Hind wing with a frenulum and three internal nervures.*

 Heterocera could be arranged in a linear series.
