d" . Black; parts of under-surface and of legs castaneous. 

 Upper-surface glabrous, lower-surface, legs, and upper parts 

 of pygidium with dense, somewhat reddish hair. 



Head almost impunctate , rather deeply concave between 

 eyes; clypeus semicircular, deeply concave; mentum very 

 prominent. Antennae ten-, club three- jointed. Prothorax 

 very largely excavated, sides and apex armed; cavity trans- 

 versely and obliquely strigose, elsewhere with sparse 

 punctures. Elytra subquadrate; striation very feeble, with 

 a distinct row of small punctures in sutural stria, but elsewhere 

 almost or quite impunctate. Pygidium with punctures only 

 about base. Legs very thick and strong; spurs of hind tibiae 

 long, parallel-sided, obtusely pointed and unequal. Length, 

 18-24 mm.

Belongs to the same section of the genus as dispar, 

 mullerianus, and turritus, from the two latter distinguished 

 by its entirely black upper-surface, and from the former by 

 its compound medio-frontal horn of pronotum, smooth elytra, 

 etc. The size and armature of the prothorax vary considerably 

 on the three specimens before me ; on the type its greatest 

 width is considerably more than that of the elytra, but on the 

 smallest specimen its width is equal to that of the elytra; the 

 cavity is so large that, on the largest specimen, the distance 

 between the tips of the lateral projections is equal to the width 

 of the elytra; the lateral projections appear to be acutely 

 elevated parts of the sides, from the base each curves forward 

 till becoming vertical, at the middle of its front face there is 

 a transverse cavity, emarginate in front; the median projection 

 of the largest specimen overhangs and passes the head, with 

 its tip notched so as to appear bifid from behind, and V or 

 Y shaped from in front; on the smallest specimen it does not 

 pass the head, and its point is almost simple.

d" . Black ; elytra bright-red, parts of under-surface and 

 of legs reddish. Upper-surface glabrous, under-surface, legs, 

 and upper parts of pygidium with dense, reddish hair. 



Head with fairly numerous punctures, rather deeply 

 concave between eyes; clypeus semicircular, deeply concave, 

 and vertical ; mentum very prominent. Antennae ten-, club 

 three-jointed; rami almost as long as head is wide. Prothorax
