moderately aculeate and strongly sinuate above the lateral excava- 

 tion, or with the median lobe distinctly quadri-tuberculate, the 

 lateral excavation very deep and the outer edge of it produced into 

 a triangular, sub-porrect tooth, the posterior part is comparatively 

 short but very convex, closely punctulate, and has a median longi- 

 tudinal impressed line extending to two-thirds of the length, the 

 anterior excavations are filled with rugose punctures, but the median 

 part is asperous, the lateral foveas are very distinct and they have 

 underneath a diagonal ridge reaching to the outer margin ; elytra 

 very convex, short, very finely striate, the striae are very shallow, the 

 intervals closely punctulate, and the three adjoining the suture are 

 8ub-tectiform at the apex of the declivity and roughly punctured 

 there. 



Female : Entirely shining ; the prothorax is not very convex, but 

 the elytra have the same shape as in the male ; head narrowly but 

 deeply incised with the angles of the incision slightly recurved ; the 

 sculpture is similar to that of the male, but it bears on the vertex 

 a very short, triangular tubercle ; the prothorax is covered with 

 round but not deep punctures which become asperous in the anterior 

 part and on the sides, it has a nearly obsolete obtuse ridge in the 

 anterior part, and a median longitudinal impressed line deeply 

 punctured ; elytra a little longer than in the male but equally 

 convex, they are finely and closely punctate, the suture and the 

 two or three intervals adjoining are a little raised and roughly 

 punctured. 



Length 19-20 mm. ; width lO-ll^ mm. 



The figure given on plate xxxiii. is that of a small development 

 with not very deep lateral thoracic cavities.

Male : Black, shining ; head twice as broad as long, clypeus 

 broadly emarginate in front and with the edges distinctly recurved, 

 genaB in a line with the lateral part of the clypeus, on the anterior 

 part of the head there is a compressed, ensiform horn with a tri- 

 angular compressed median tooth in the posterior margin, and 

 behind the base of the horn there is a transverse, slightly quadi-i- 

 dentate, little raised carina extending nearly from eye to eye, the
