This gcDus includes a few S. African ^' 7rog!ops" with 

 simple 5-jointe(l anterior tarsi in J". The type, J*, is 

 D. natalensis, Gorh. (= Hedi/bius cavifrons, Boh,, and Chali- 

 corus ferox, Ab.). The apterous ? ? resemble those of the 

 Palaearctic genus Charupus, and two of them have, in con- 

 sequence, been described under different generic names. The 

 S S oi D. albonotaius, Pic, are dimorphic, and the ? ? 

 liere referred to D. cavifrons have immaculate elytra. 



1 (0). Elytra] markings extending along whole or part of 



outer margin. 



2 (3). Elytra with the marginal streak complete ; epi- 



stoma with a sulcate triangular plate behind 

 the epistoma, tlie cephalic cavity biniaculate in 

 front Species 1. 



3 (t?). Elytra with the marginal streak incomplete. 



4 (u). Epii-tonia fiat, with a transverse plate behind, the 



ceplialic cavity not divided Species 2. 



5 (4). Epistoma excavate, without plate behind, the 



cephalic cavity transversely sulcate Species 3. 



6 (1). Elytral markings wanting along the outer margins. 



7 (10). Elytra narrowly bifasciate, the submedian fascia 



interrupted at suture, the other apical. 



8 (9), Epistoma flattened . . '. Species 4. 



9 (8). Epistoma excavate Species 5. 



10 (7). Elytra with three transversely-placed .spots — one
