Head and prothorax brassy ; antennae pubescent, black, with the 

 two basal joints pale yellow ; head nearly smooth ; prothorax nearly 

 one-half broader than long, truncate at the apex, with the outer sides 

 crescent-shaped, the posterior angle much rounded and the median 

 part of the base produced a little beyond the outer angles, faintly 

 plicate, and grooved in the centre ; elytra broader at the base than 

 the prothorax at its widest, with the outer angles slightly rounded, 

 hardly ampliated behind, a little convex, smooth, with one or two 

 faint striae along the suture, pale yellow with a black narrow margin 

 dilated into a round patch at about the middle and reaching the 

 suture, the infuscation ascending a little the suture at the apical

 1^ mm. 



Hah. Cape Colony (Worcester, Stellenbosch). 



LiONYCHUS BASALIS. 



Shape, size, and colouring of L. cinctus, but the three basal joints 

 of the antennae and also the tibiae are flavescent ; the sculpture of 

 the elytra is identical, but the infuscate margin is a little narrower, 

 not dilated into a median marginal patch, and there is a basal sub- 

 diagonal black line near the base which seems to consist of two 

 elongated coalesced patches reaching from the suture to about the 

 median part of the disk; under side black. Length 3-3J mm. ; width 

 1^-1^ mm.
