In this genus the anterior wings are elongate, the outer margin oblique and slightly convex; the 

 disco-cellular nervules are obliquely directed inwardly, and the base of the second median nervule is about 

 three times as far apart from that of the lower as from that of the upper median nervule. The body is 

 robust and pilose, the palpi broad and hairy, projecting forward and almost level with the upper surface of 

 the head ; antennae with a pyriform club, the apex of which is slender and shghtly hooked. 



Two species are here enumerated as found in the Malay Peninsula. 



1. Isma obscura. n. sp. (Tab. XXXV., fig. 19.) 



Wings above dark fuscous ; anterior wings with five greyish spots, situate two — small — in and before 

 end of cell, two — largest — beneath cell and divided by the second median nervule, and one between end of 

 cell and apex of wing. Wings beneath paler than above ; anterior wings spotted as above, and with the 

 inner marginal area greyish ; posterior wings with the abdominal area paler. Head and thorax above 

 more or less greyish; legs brownish. Abdomen mmtilated.

 transparent spots bordered below with brown, and with a brown spot on each side of them."
