baud sinuata, angulis posticis rectis, anticis baud prominulis ; scu- 

 tellum leve ; elytra prothorace basi nonnihil, pone medium tertio 

 latiora, sub-oblonga, modice convexa, striata, striis granoso- 

 punctatis, interstitiis granulis confertim seriatis instructis ; corpus 

 subtus glabrum, nitidum ; pedes rugosi, brevissime pubescentes. 

 Long. 11-15 mm.; lat. 6-8i mm. 



Allied to A. alternans, Wied., in general appearance, but the 

 prothorax is shorter, the granules are more numerous and more 

 closely set, and the strigillate folds are better denned ; the sculpture 

 of the elytra is very different.

GEN. HOPLONYX, Thorns. 



HOPLONYX ASPER. 



Niger, opacus, supra glaber ; antennae longae, graciles, breviter 

 pubescentes, articulis sex ultimis flavescentibus ; caput crebre 

 rudeque punctatum ; prothorax longitudine fere quarto latior, 

 nonnihil rotundato ampliatus, antice perparum attenuatus, basi 

 apice paullum latior, totus marginatus, vix convexus, granulis con- 

 fertis dense obsitus ; scutellum longum, acute triangulum ; elytra 

 basi prothorace fere duplo latiora, parallela, versus apicem attenuata, 

 supra parum convexa, anguste striata, striis distincte granosis, inter- 

 stitiis tuberculis parvis acutis confertim seriatis instructis ; corpus 

 subtus laxe punctulatum pilosulumque ; pedes rugosi, brevissime 

 pubescentes. Long. 13-13| mm. ; lat. 6 mm. 



Easily distinguished by the granulose prothorax, and the series of 

 small tubercles on the elytra ; no other South African species has a 

 similar sculpture.
