 right angle with the fastigium of the vertex; its surface 

 strongly punctured throughout, distinctly impressed 

 below the middle ocellum, slightly convex between the an- 

 tennae; its margins slightly raised, not punctured, gradually 

 and feebly divergent from fastigium to the clypeus, Fasti- 

 gium of the vertex rotundato-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 tlie 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 

 ])ronotum distinctly tectiform, dull, indistinctly rugulose 

 throughout ; hind angle straight ; lateral lobes indistinctly 

 rugulose throughout, except in the hind upper part of the 

 metazona, which i'S densely and rather coarsely punctured ;

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

 both Avidely rounded. Mesopleurse and metapleurse slightly 

 rugulose. Elytra reaching tlie hind knees ; the mediastinal

 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 elytia, rather broad, its transverse veinlets thick, more 

 regularly dis[)osed than in ^1. africanus, the false vein well 

 (l('veh)ped, 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 thau broad, with margins straight. Cerci straight,
