Black, very shining ; head very broad, mandibles broad and very 

 long ; head and protljorax of the usual shape ; elytra long, not much 

 narrowed at the base, and very little ampliated in the centre (16 to 

 29m.m. across the shoulders, 20 to 23 in the middle, and 19-21'°*'"' at 

 the top of the declivity) ; plane on the disk, sloping gradually behind, 

 and declivous at the apex, margins closely and sharply serrated, the 

 whole of the upper part covered with a closely set, prominent granu- 

 lation, and much more developed on the declivity than on the dorsal 

 part. 



Length, 45-47 ; width, 20-23"'-"- 



Although my examples of latipennis are, as a rule, not much am- 

 pliated in the middle, yet I have received one, the elytra of which are 

 as broad as those of scahra (lO""*"* across the shoulders, 2b^*^' in the 

 middle, and 21 at the top of the declivity), the discoidal part is, how- 

 ever^ longer, and the hind part is not so much raised. 



Female : Colouring of the male, elytra with the whole of the disk 

 conspicuously granulated.

Male : Black, moderately shining ; head, mandibles and prothorax 

 shaped like those of latipennis ; elytra long, not much narrowed at the 

 base, a little ampliated in the middle (2I'"*™* across the shoulder* 

 24™*'"* in the middle, and 23 at the top Of the Heclivity), plane on the 

 disk, gradually dehiscent behind, with the sutural apical part deeply 

 depressed ; the granulation on the elytra, although close, is not much 

 pronounced, and is denser on the sides than on the disk.
