Hab. Damaraland ('? Walfish Bay). 



GEN. DIPLOCOTIDUS. 



Palpi fere ut in Ptino ; caput antice verticale, vertice valde 

 elevato ; oculi prominentes ; antennae longitudine corporis, articulo 

 basali valido, crasso, sub-flexo, apice oblique truncate, secundo 

 primo duplo breviore, in latero ejusdem sito, 3-5 elongato-conicis, 

 latitudine apicali fere tertio longioribus, 6-10 sub-turbinatis, in- 

 trorsum linearibus, extrorsum apice angulatim productis, articulo 

 ultimo praecedenti tertio longior, conico, a tertia parte attenuate, 

 apice acuminate ; prothorax bi-partitus ; scutellum obliteratum ; 

 elytra ovata ; coxae validissime product, globosae, anterioribus sat 

 approximatis, intermediis distantibus, posticis transversim late 

 -disseptis ; abdominis segmentum basale aiigustissimum, vix per- 

 spicuum ; pedes elongati, sat crassi, unguibus brevibus. 



The general facies is not unlike some species of Ptimts, but it is 

 easily differentiated by the highly raised frontal part of the head 

 supporting the antennal tubercles, the very great development of 

 the coxae, and the reduction of the basal segment of the abdomen. 

 It resembles very much Diplocotes, an Australian genus, and might 

 prove to be identical in spite of the difference in the shape of the 

 last joint of antennae and of the prothorax, but the coxae are much 

 more broadly separated longitudinally, the posterior ones being 

 almost contiguous to the fold of the elytra.
