and forming thus two somewhat oblong, transverse enclosed spaces, 

 clypeus deeply incised triangularly, and with the angles of the 

 incision sharp ; antennae wuth the intermediate joints rufescent, and 

 the club ashy grey ; prothorax moderately arcuate laterally, slightly 

 emarginate above the outer angle, thickly fringed with black setee, 

 all the walls of the impressions bearing fascicles of dense, black 

 setae ; scutellum triangular, grooved longitudinally in the middle ; 

 elytra elongate, slightly emarginate laterally a little before the median 

 part, not serrate along the outer margin which is fringed with thick 

 black setae, and having on each side four costae with equi-distant, 

 somewhat long penicillated tubercles, separated by somew^hat broad 

 intervals filled with series of shallow geminate not very deep 

 punctures with slightly raised walls, but not divided by a median 

 costa or raised line ; anterior tibiae with the two apical teeth divided 

 by a shallow emargination ; basal tooth ante -median, and followed 

 by a very distinct sharp serration right to the elbow, in most 

 examples, however, this serration is nearly obliterated, but the first 

 tooth above the basal one is nearly always distinct ; intermediate 

 and posterior tibiae with rows of stiff black bristles, but not denticu- 

 late ; prosternum with a short, acuminate process ; wings under the 

 elytra. 



Length 7-10 mm. ; width 5-6 mm.

Black, opaque, with all the fascicles of ciliae light brown ; clypeus 

 sharply triangular ; head rugose, and with the normal transverse 

 frontal carinae slightly interrupted in the centre, and the median 

 longitudinal carina very distinct ; the transverse caringe are densely 

 squamose ; antennae sub-ferruginous and with a sub-flavescent club ; 

 prothorax only moderately arcuate laterally in front and densely 

 ciliate along the margins ; the median longitudinal furrow is twice 

 interrupted, and the walls of it, as well as all the tubercles, are 

 densely squamose, almost cristate ; scutellum ver^* small, almost 

 indistinct ; elytra sub-elongate, a little sinuate laterally above the 

 median part, not serrate laterally, but somewhat densely ciliate 

 along the outer margins, and having on each side besides the suture 

 w^hich is similarly fasciculate, four tuberculated costae bearing closely 

 set equi-distant fascicles of dense ciliae, intervals filled with trans-
