 to over one balf of tbe \viclth, frontal ridge very much raised and 

 curved laterally as far as the edge of the base which is sub-carinate 

 and has a short, sharp triangular tubercle in the centre ; prothorax 

 canaliculate from the base to near the median part, the end of the 

 groove hmited by a very small tubercle ; anterior tibiic ending in 

 a sharp inward tooth slightly curving downward at tip, and having 

 beneath a distinct laminate ridge, and a little lower down a vertical 

 spine in a line with the second basal outer tooth ; intermediate 

 tibiK produced at a short distance from the knee into a large 

 quadrate laminate process the anterior angle of which is very 

 sharp and projects a little ; anterior femora very thick, their anterior 

 margin has a very small spine curving outwardly and situated near 

 the apex, the posterior margin has a very conspicuous, broad, 

 sub-lamelliform vertical tooth at about the median part ; XDrosternum 

 produced beyond the coxa? in a long process broadly bifid at tip, 

 and more or less anchor-like ; intermediate femora very thick and 

 emarginate at tip underneath, posterior ones with a sharp and long 

 horizontal spine on the upper side ; posterior tibiae dilated triangu- 

 larly from a short distance from the knee, and having inwardly 

 a sharp lamina not quite as broad as the one on the intermediate 

 ones, and also very little angular at tip. 



Female : Clypeus rostrate, sculpture of head similar to that of 

 the male, and carinaa similar, but the edge of the base is produced 

 in a trifid carinate process with a distinct ridge at the base of it ; 

 the prothorax is shorter and rather deeply excavated in the middle, 

 and the excavation is clothed with fulvous hairs ; the elytra are as in 

 the male ; the pygidium is more granulate ; the anterior tibiie are 

 strongly quadri-dentate outwardly and have an horizontal spur 

 inwardly, but are neither laminate nor dentate beneath ; the median 

 femora are not emarginate at tip, but the intermediate and posterior 

 tibict. are gradually ampliated triangularly inwardly from a short 

 distance from the knee ; the posterior femora have no spine on the 

 anterior edge, and the punctures on the intervals of the elytra are 

 a little deex^er than in the male.
