 basal cell ochraoeous. Apex of exterior ulnar area narrower than in D. 

 mannifera (Linn.), Dist. 



Opercula short, not reaching apex of 2nd abdominal segment, 

 subtriangular. Anterior femora with two strong spines.

British Borneo (collns. Edwards and Kirkaldy). 



This species seems to belong to the typical subgenus by the short 

 rostrum which just passes the intermediate coxse, but it differs from 

 its consubgeners by the less swollen and narrower frons and by the ocelli 

 being about twice as far from the eyes as from one another ; unfor- 

 tunately, I have seen three females only.
