154 M. Louis Peringuey on new genera and species of 



reaching from the anterior horn to the base ; prothorax truncate 

 in front, with a very deep, but not broad, lateral excavation, the 

 anterior part carinate, strongly sinuate laterally above the exca- 

 vation, and with the median part produced into a horizontal, very 

 long, compressed process with a perpendicular conspicuous tooth 

 underneath ; this horizontal process extends as far as the clypeal 

 horn, which it overhangs. In the ^ the head has a short, trans- 

 verse occipital carina, the prothorax is not so much raised, is deeply 

 sinuate in front, depressed, but not excavated, aud the median 

 part is produced into a projecting carina, overhanging a little the 

 apex, and so deeply emarginate in the middle as to be almost bifid. 

 Length 32-37, width 20-21 mm. 



Hal'. Zambezia (Maiiica, Mazoe). 



Its nearest ally is H. neptunus, Bohem. The sculp- 

 ture of the head and prothorax is alike, the tubercles at 

 the base of the elytra are also similar, but the horn of 

 the clypeus is very much shorter, and the elongated 

 horizontal process of the prothorax is very different. 



Gen. Onitis, Fabr. 



0. zamhezianus, n. sp. 

 Reddish-brown, with the elytra opaque ; head finely plicate 

 transversely on the clypeus, granulate behind, clypeus elongate in 

 the anterior part, more so in the $ than in the $ , without any 

 clypeal carina, but with the frontal one sharp and very much raised, 

 vertex almost bi-impressed, posterior edge very distinctly raised ; 

 prothorax moderately convex, broad, carinate in the anterior and 

 lateral parts, closely punctured from the base to about three-fourths 

 of the length, posterior part nearly impunctate ; elytra elongate, 

 convex along the sutural part towards the middle, very finely 

 striate, with the intervals plane and smooth ; underside piceous- 

 brown, metasternum closely punctured and densely hairy, abdo- 

 men nearly smooth, but with a few lateral setigerous punctures; 

 anterior femora of the $ thick, grooved underneath, and with an 

 acute ridge, bearing a sharp tooth in the middle of the groove and 

 a smaller apical one in the anterior part of the apex ; tibioB long, 

 straight, moderately thick, multi-denticulate inwardly, having a 

 double ridge on the upper part, strongly quadri-dentate externally, 

 and with the inner apical tooth very long and incurved ; inter- 

 mediate femora deeply incised at the apex, carrying a sharp 

 median posterior carina, developing into a sharp tooth, apical part
