Fuscous brown, little shining ; clypeus elongate, bi-dentate late- 

 rally and deeply incised in front, somewhat roughly punctured 

 and setulose ; prothorax sub-parallel laterally, and having a broad 

 median longitudinal impression, and four latei'al ones the edges of 

 which are indicated by very thick, short setae ; elytra with a trans- 

 verse diagonal flavous band extending from the humeral angle to 

 the median part of the suture, and an apical spot of the same 

 colour, as broad as the base of the prothorax, w-ith the shoulders 

 very well defined and tuberculate, straight laterally, but tapering a 

 little from base to apex, plane on the disk with the suture slightly 

 raised, and having two discoidal sharp cost^ and a very short supra- 

 humeral one on each side ; the suture and the costa? have a series 

 of thick short settc which are much longer and slightly decumbent 

 at tip at the apex ; pygidium fringed at the top by moderately long 

 bristles and having two median series of squamiform setae diverging 

 towards the apex ; abdominal segments, except the penultimate, pro- 

 jecting much beyond the sides of the elytra, and giving thus to the 

 dorsal surface the appearance of being ampliate at middle ; legs 

 rufescent, anterior tibiie quadri-dentate outwardly, basal tooth 

 short, the others gradually longer ; intermediate and posterior 

 spurs very long. 



Male : Clypeus more elongate than in the female, and bearing 

 a long, sub-porrect or curving backward horn situated at the apex 

 between the two angles of the incised part ; in the anterior part of 

 the prothorax, which is slightly declivous in front, are two long, 

 slender horns curving forward and not diverging ; metasternum 

 with three very distinct longitudinal carinas ; the cephalic and 

 thoracic horns vary in length from 4i to 11 mm. 



Female : The clypeus is more deeply emarginate in the centre, 

 and without clypeal horn ; the prothorax has also no horn, the 

 impressions are similar, but the median one is divided in two, 

 and the anterior part is not declivous, the median impression is 

 broadly but not deeply punctate. 



Length 5-6 mm. ; wadth 2-3 mm.
