 elytral punctation, from D. nigrwuma St. in the unspotted 

 thorax, colour of the underside, (fcc. ; also in the same way from 

 D. ohsGwimana St, D. flavida St. has the elytra geminate- 

 punctate. I know only of a single specimen of this species, 

 contained in my collection without detailed locality.
