distinctly reclinate; frontal ridge in profile sliglitly convex 

 above the middle ocellum, forming a widely rounded 

 right angle with the fastigium of the vertex; its surface 

 strongly punctured throughout, distinctly impressed 

 helow the middle ocellum, slightly convex between the an- 

 tennae; its margins slightly raised, not punctnred, gradually 

 and feebly divergent from fastigium to the clypeus. Fasti- 

 gium of the vertex rotuudato-pentagonal, distinctly longer 

 than broad ; its surface distinctly impressed ; the median 

 keel starts from its hindmost part and extends almost 

 to the pronotum, very feeble throughout ; the lateral 

 occipital keels feeble, very irregular, distinctly diver- 

 gent backwards. Temporal foveolse distinctly but not 

 much longer than broad, with the apex widely obliquely 

 rounded. Pronotum only feebly compressed laterally, not 

 constricted, rounded ; the median keel strongly raised, cut 

 by the third sulcus in its middle ; lateral keels very feeble 

 and irregular, distinctly convergent between the fore margin 

 and the first sulcus, divergent behind the latter, on the 

 metazona developed in its foremost part only; the disc of 

 pronotum distinctly tectiform, dull, indistinctly rugulose 

 throughout ; hind angle straight ; lateral lobes indistinctly 

 rugulose throughout, except in the hind upper part of the 

 metazona, which is densely and rather coarsely punctured ; 

 their lower margin is very widely rotundato-angulate behind 

 the middle ; their fore angle obtuse, hind angle straight, 

 both widely rounded. Mesopleurse and raetapleurse slightly 

 rugulose. Elytra reaching the hind knees ; the mediastinal 

 area extending almost to the middle of the fore margin, 

 dilated in its middle, with a very distinct, straight, false 

 vein ; scapular area occupying more than three-quarters of 

 the fore margin, strongly dilated beyond its middle, with 

 very oblique, sparse veinlets ; externo-median area slightly 

 dilated ; the first and second radial veins perfectly straight; 

 the discoidal area extends distinctly beyond the middle of 

 the elytra, rather broad, its transverse veinlets thick, more 

 regularly disposed than in ^1. (ifricanus, the false vein well 

 (k'veloped, straight; the interulnar area about as broad as 

 the discoidal, with two rows of cells and an irregular, 

 interrupted false vein. Hind femora short, thick, and 

 dilated basally. Supra-anal plate triangular, distinctly- 

 longer than broad, with margins straight. Cerci straight, 

 about as long as the supra-anal plate. Subgenital plate 

 obtusely conical. 



General coloration greyish brown. Head above ash-grey,
