There are males and females in the Indian Museum coll. from 

 Calcutta and Tenasserim with the apices of fore tibiae, the fore tarsi 

 whoU}' and the others partly brown, which may perhaps justify their 

 being divided from this species, but the material is too poor for 

 decision on this point at present.

[Atylotus fiaviventris, Bigot, in parte.] 



Type 9 and seven others from Shillong, Assam (H. M. Lefroy,

 the larger frontal callus, by the third joint of antennae being bright 

 reddish yellow, black at apex, and rather wider at the base, by the 

 more slender palpi and by the rather Hghter coloured abdomen.
