broad as the very narrow prothorax, and with the humeral angles- 

 rounded off, parallel from a short distance from the humeral part to 

 about the same distance from the apical, plane with the margins 

 strongly reflexed, narrowly yet deeply striate, the striae impunctate, 

 yet having faint and remote transverse impressions, intervals raised, 

 somewhat sharp in the anterior part. 



Easily distinguished from the other two South African species by 

 the very narrow prothorax and sub-parallel elytra.

 XENITENUS NATALICUS, n. sp. 



Head, prothorax, and pectus testaceous-red, elytra black, antennae 

 with the three basal joints reddish, the others fulvescent, palpi 

 reddish ; head impunctate ; prothorax as broad as long, straight 

 laterally, slightly narrower at the base than across the apex, and 

 with the outer margins slightly reflexed, very faintly plicate ; elytra 

 with the shoulders moderately rounded, sub-parallel, strongly 

 sinuate behind and with the inner apical part being accordingly 

 sharper, they are plainly striate, the striae are impunctate, and the 

 intervals are moderately convex ; legs piceous-brown or red, 

 abdomen black. 



Not unlike in general appearance X. dilucidus, Pering., but the 

 prothorax is more parallel, and as the margins are reflexed, there 

 seems to be a somewhat broad lateral sulcus ; the elytral apical 

 margin in X. dilucidus is not deeply sinuate, nor the inner angular 

 part acuminate as in X. natalicus.

LlONYCHUS LAETULUS, n. Sp. 



Bronze black, with a brassy sheen on the upper side, antennae 

 black with the three basal joints rufescent ; elytra with a very broad 

 yellowish-white band on each side of the dorsal part ; head broad, 

 impunctate ; prothorax of the normal shape, very shiny and 

 metallic ; elytra sub-elongate-quadrate with the humeral and posterior 

 parts equally rounded, black but narrowly fuscous alongside the
