exception of the apical part of the basal joint, nearly the whole of 

 the second and third are infuscated ; prothorax slender, cylindrical 

 from the apex to two-thirds of the length, narrowed above the base, 

 briefly pubescent, deeply punctured with an extremely narrow, 

 hardly discernible median groove, red with a purplish tinge ; elytra 

 elongated, very slightly ampliated from the middle, moderately 

 convex, punctato-striate with the intervals plane and closely punc- 

 tured, almost shagreened, very briefly pubescent, and bright green ; 

 under side red, abdomen dark blue, base of femora red, the remainder 

 and the tibiae black, with the tarsi infuscate. Length 12-13 mm.; 

 width 3J-4 mm. 



D. australis is probably a slight variety of D. Bocandei, Laf., from 

 Senegal and Old Calabar. Its likeness to Drypta ruficoUis is so 

 great that but for the pectination of the claws of the tarsi it would 

 ^be difficult to distinguish between them.
