brownish yellow, stigma honey-yellow ; the two upper veins from 

 the discal cell very approximate at their bases, the upper one a 

 little turned downwards ; anal cell closed well before the border. 



Length, 8 mm. 



Described originally from a single 5 from Tillangchong, Nicobar 

 Islands. 



This species, which has not been seen by me, is said by Schiner 

 to differ from C. ferntginosus, Wiecl., by the absence of the 

 brownish wing-tip and the honey-yellow stigma. The two shining 

 white spots abo\e the antennae seem characteristic, otherwise the 

 differences from VV^iedemanu's species appear slight.
