Sliiniii^r hlack (;); dull black, with the <fr('atcT part of" 

 each elytron, or with j)art.s of the head, proiiotum and elytra 

 orange ; or orange, with the nuDulibles, ])art of the head, 

 the middle of the j)roiiotuni, the seiitelluin and a narrow 

 sntural stripe dilating towards the base of the elytra black (^). 

 The femora usually red, exce])t at the base and ai)ex, in both 

 sexes. Rather narrow \n shape and not very convex, the 

 sides of the prothorax rounded, serrate in the female, and 

 bearing rather strong and close tubercles in the male. The 

 piosternum very little elevated and not compressed or pointed 

 behind. 



9. Black and shining. The head is rugosely [)uncturcd, 

 with the ocular canthus moderately j)rominent laterally. The 

 jtronotKni is strongly ami closely j)unctured at the sifles, very 

 minutely and sparsely in the middle. The front angles are 

 rather blunt, the sides finely serrate, gently rounded to ])ast 

 the middle, where there is a minute s[)ine, antl feebly concave 

 to the hind angles, which are rounded. I'he elytra are closely 

 but very finely punctured, with the sides and apices rather 

 more strongly j)uncturcd but not opaque. The mentiiDi is 

 ('(xuscly rugose. The wflaHtoiiutn and aJxlomrn, are rather 

 dull but not distinctly punctured. The front tihia is stout, 

 broadly forked at the end, with runnerous short, shar|) lateral 

 teeth, and the middle and hind tibia' have each a strong 

 lateral sj)ine. 



.^. Black, not shining, with the elytra reddish-yellow, 

 excejit a narrow outer mai-gin and a sutural stripe triangularly 

 dilated in front and reaching the shoulders ; sometimes also 

 with jjatches of the yellow colovn- in each angle of the pronotum ; 

 sometimes with the head more or less yellow, the pronotum 

 with a broad yellow mai'gin on each side, but with the extreme 

 outer edge and a median spot on each side black, and the 

 elytra yellow, with very narrow black external and sutural 

 margins. The femora and the sides of the metasternum may 

 be more or less decorated with the yellow colour. 



The head is short, not very large but relatively brctad, very 

 finely and densely granular. The ocular canthus is very 

 obtusely angular in front and extends to tlie middle of the 

 eye and the sides are strongly convergent behind the eyes. 

 The clyjK'al process is large, transversely ])entagonal, ratluM' 

 sharply tridentate in front. The mandibles are very long and 

 slender, strongly arched, studded internally with closely-set
