transversely strigillate ; pygidium with shallow, scattered punctures ; 

 under side similarly sculptured. 



The white markings of this species are very variable. According 

 to West wood, the typical specimen, still preserved in the Banskian 

 Collection of the British Museum, has the hind part of the head with 

 an irregular white mark ; the apex of the elytra is scarcely marked 

 with white ; the sides of the metasternum have an irregular white 

 mark, and the abdominal segments have on each side a row of 

 spiracle-like white dots. 



Length 11-12 mm. ; width 6-6^ mm. 



Hab. The whole of South Africa.

Mentum convex, divided from the ligular part by a sharp trans- 

 verse keel, the outer face sloping thus equally towards the base and 

 towards the apex, the labial cavity is angularly produced at the 

 base, and the last joint of the labial palpi is broadly swollen out- 

 wardly and somewhat acuminate, the upper margin of the ligula is 

 broadly arcuate ; maxillae robust and very hairy, the upper lobe 

 armed with a long, falcate, very sharp tooth, and the inner one with 

 a shorter, simple one ; antennae of the usual type ; clypeus narrowed 

 in front with the margin slightly reflexed, the head is separated 

 from the clypeus by a very plain keel extending from one canthus of 

 the eyes to the other ; prothorax strongly attenuated laterally from 

 past the median part to the apex, nearly straight in the posterior 

 part with the hind angle somewhat obtuse but not rounded, base 

 strongly arcuated above the scutellum which is not very much longer 

 than broad at the base ; elytra elongate, narrower at the apex than 

 at the base, deeply sulcate on the disk and on each side of the 

 suture ; pygidium sub-vertical ; spiracle of the last abdominal seg- 

 ment not raised ; prosternum with an anti-coxal vertical spine ; 

 anterior tibiae bi-dentate ; legs moderately robust ; joints of tarsi
