forward, grooved along the margin, the outer edge refiexed ; 

 abdominal segments roughly plicate longitudinally ; ante-coxal pro- 

 sternal process as in the four preceding species. 



Length 7-8 mm. ; with 2J-2^ mm. 



Hab. Transvaal (Klerksdorp, Pretoria, Potchefstroom) ; Southern 

 Ehodesia (between Limpopo and Zambesi). 



Trichoplus paradoxus, n. sp. 

 Plate XLV., fig. 55. 



Piceous, very glossy; clypeus impressed on each side but without 

 any central longitudinal groove, vertex of the head plainly tuber- 

 culate, surface most finely punctulate, the punctures remote and 

 each bearing a most minute hair ; prothorax deeply excavate in the 

 centre, the excavation edged in front by a round, semicircular wall, 

 roundly carinate laterally, the carina incised at about the median 

 part and continued thence as a highly marginate ridge overhanging 

 the base, but emarginate in the centre, the excavation runs thus 

 from the anterior to the extreme posterior part, the lateral margin is 

 deeply incised at about the median part where it unites with the 

 incised part of the lateral wall of the excavation, and the basal 

 angles project to a considerable distance, the excavation and also 

 the sides are impunctate, and the lateral part between the outer 

 margin and the lateral wall of the excavation is slightly excavate, 

 but the edges of the incised part of both the dorsal excavation and 

 also of the lateral margin are fringed with a few thick, fulvous hairs ; 

 epimera very transverse ; elytra somewhat deeply sinuate laterally, 

 slightly ampliate past the middle and having the suture very highly 

 carinate, and on each side an equally sharp dorsal costa with a 

 somewhat depressed space on each side of it, on the surface are 

 scattered small, obsolete punctures bearing each a most minute hair; 

 propygidium simple sparsely punctulate, the punctures briefly seti- 

 gerous ; pygidium with the upper side strongly sloping backwards in 

 a very broad lamina, attenuate rounded laterally, and with the 

 median part produced into a long, triangular spine-like process 

 slightly blunted at tip, the part of the pygidium overhung by the 

 basal lamina is directed forward almost sub-horizontally, and is 

 slightly convex in the centre ; under side almost impunctate ; ante- 

 coxal process of the pronotum of equal thickness ; femora and tibiae 

 more slender and longer than in the other species of the genus. 



Length 12 mm. ; width 4 mm. 



Hab. Transvaal (Pretoria). 



I have seen one example only of this most singular species.
