closely set, sharp granules ; protliorax one-third longer than broad, 

 deeply emarginate in front, marginate all round, gradually, although 

 slightly, attenuate laterally in front for about one-fifth of the length, 

 hardly ampliate in the centre, but diagonal from a little past the 

 median part to the outer angle, and also slightly sinuate above it, 

 basal impressions deep, conspicuous, there is also a narrow, elongate 

 one along the base on each side next to the basal angle, the surface 

 is punctulate and sub-granular laterally, and there is a faint trace 

 of a longitudinal line in the middle of the disk ; elytra nearly parallel, 

 deeply striate, intervals rugose, fifth and seventh raised, sub-tectiform, 

 eighth very sharply carinate from the basal angle to the rounding of 

 the apical part ; pygidium roughly granulose ; metasternum v^ith a 

 transverse, very deep cavity at base, and having in the middle, for 

 about two-thirds of the length, two much-raised, thick, roughly 

 punctured longitudinal ridges enclosing a very broad groove, 

 median part of metasternum sharply and conspicuously carinate ; 

 legs massive, anterior femora with the end of each trochanter 

 produced in a sharp, triangular dentiform process, and armed with 

 a short tooth near the base, and a long and sharp one at about the 

 middle of the anterior edge (fig la) ; anterior tibia? falcate at tip, long 

 and having in the inner part a narrow, laminate process gradually 

 attenuate from near the base, where it is deeply emarginate, to the 

 curve of the anterior part, this process is strongly crenulate, inter- 

 mediate and posterior femora compressed, the former very dilated, 

 and having an acute cariniform process beneath broadly incised 

 towards the apex, and ending in a sharp, triangular tooth ; posterior 

 femora grooved underneath, but 'not mucronate ; the sides of the 

 metasternum are closely granulate, and the legs are rugose, and the 

 apical part of the intermediate coxae are also granulate ; scutellum 

 distinct, truncate at tip. 



Female : Clypeus rostrate, femora simple, tibiae shorter and 

 broader ; anterior ones slightly incurved, and finely crenulate 

 underneath. 



Length 44 mm. ; width 19 mm.
