long greyish erect pubescence ; elytra with a distinct sutural and 

 apical band of white, appressed, slightly squamulose hairs obliterated 

 close to the apex of the scutellum, there is also a faint trace of a 

 discoidal and of a supra-marginal line of similar hairs ; the pygidial 

 part and abdomen are covered with appressed hairs more flaves- 

 cent on the pygidium than on the abdomen ; clypeus very scabrose, 

 slightly attenuate laterally, straight at the apex with the angles 

 sharp and reflexed, and a slight prominence in the centre of the 

 reflexed margin ; prothorax very closely scabrose except on the 

 median basal part, which is punctured, it has a distinct median 

 longitudinal groove ; scutellum densely hairy ; elytra very plainly 

 sinuate laterally and attenuate towards the apex, irregularly and 

 somewhat closely punctured, not costulate but having two longi- 

 tudinal impressions ; anterior tibiae tri-dentate, the apical tooth is 

 very slanting, but the other two, although not quite connate at the 

 base, are set at right angles somewhat in the fashion of Hctcro- 

 cheliis, among which this species should be placed but for the 

 stronger hind claw being deeply cleft at the tip. 



Female : Exactly like the male, but a little more robust ; it can 

 be distinguished by the shape of the pygidium only. 



Length 5-7-| mm. ; width 3-3^ mm.

Male : Black, with a very faint metallic tinge ; prothorax clothed 

 with a moderately short, dense greyish pubescence ; scutellum 

 hairy, elytra with three moderately distinct bands of appressed 

 greyish hairs, the median one of which is obliterated past the 

 middle ; pygidial part, abdomen and legs clothed with appressed 

 hairs flavescent on the pygidium, greyish elsewhere; head finely 

 scabrose, clypeus slightly attenuate laterally, plainly tri-dentate at 

 apex and with the teeth reflexed ; the prothorax is finely scabrose 

 all over ; scutellum clothed with greyish hairs ; elytra plainly 

 sinuate laterally and attenuate towards the apex, bi-impressed longi- 

 tudinally on each side, the juxta-humeral impression being deeper 

 but shorter than the sutural one, they are closely but irregularly 

 punctured and somewhat brownish laterally, and they have a few 

 ashy grey hairs in the intervals of the hairy bands ; anterior tibiae 

 tri-dentate, but with the basal one much shorter than the inter- 

 mediate, the two, how^ever, are set close to each other and almost at 

 right angles with the tibiae ; the robust hind claw is cleft laterally,
