the tarsus. Female like the male, except that the wings are rather 

 larger and broader. Type, the "Achlyodes" vasava of Moore. 



CtenoptUum is evidently nearest allied to Odontopiiluni, raihi, but 

 differs considerably in the outline of the wings, in the shortness of 

 the costal nervure and subcostal nervules of the forewing, and espe- 

 cially in the setose clothing of the legs of the male, in CtenoptUum the 

 hairs are much longer and do not form such a large and dense mass 

 as in Odontoptihun, and are attached to the tibia of the hindlegs instead 

 of to the coxa of the forelegs. 



As far as is known to me, the genus contains but two species, 

 which occur in Sikkim, Assam, and Burma. They probably rest with 

 wide outspread wings.

Description : Male. Upperside, both wings reddish-ocbreous, 

 with numerous lustrous semi-transparent white spots. Forewing 

 with a small spot in the discoidal cell towards the base, with an elon- 

 gated spot below it in the submedian interspace, sometimes divided 

 into two ; a very large spot at the end of the discoidal cell, outwardly 

 anteriorly deeply incised ; two spots above it just below the costa 

 divided by the first subcostal nervule ; a discal curved series of ten 

 spots, of which the first four are of nearly equal size (the uppermost 

 the smallest), divided by the subcostal nervules, followed by a rapidly 

 increasing series of four spots, one in each interspace ; then by two 

 spots, the lower three times as large as the upper, in the submedian 

 interspace ; a submarginal obscure fuscous band. Hindmng with a 

 clump of spots shewing great diversity in shape and size occupying 

 the middle of the wing ; a submarginal dark fascia as in the forewing. 

 Underside, both wings coloured and marked as above, but all except the
