near the base, gradually narrowing towards tlie extremity 

 of the elytrabehind; legslong ; the three pairs nearly equi- 

 distant (in consequence of the prolongation of the pro- 

 thorax behind its acetabula) ; fore and hind thighs very 

 strongly incrassate, the former curved, and with a 

 broad blunt tooth near their extremity within ; tibiae of 

 the same pairs rather strongly arched, expanded, broadly 

 excavated, and partly fringed with long hairs within ; 

 the anterior are also thickened at their extremity ; inter- 

 mediate thighs comparatively slender, slightly thick- 

 ening from their base to near their extremity ; the inter- 

 mediate tibiee are a little curved, and slightly excavated 

 within, at their basal half; the hind and intermediate 

 tibiae are also armed with a short curved spur ; tarsi 

 furnished with a brush of short hairs beneath, and with 

 a few longer hairs on their sides and above ; the penulti- 

 mate joint of all sub-bilobate ; the first of the posterior 

 nearly as long the following united ; fore and intermediate 

 coxa3 more or less clothed with long shaggy hairs ; the 

 posterior transverse, oblique ; the anterior moderately 

 long, somewhat narrowly separated by the prosternal 

 process ; prosternum broadly concave in front, its process 

 between the coxse is narrow, very prominent, canalicu- 

 late, with the margin, at each side, raised into a long 

 obtuse tooth ; it is abruptly bent down behind the coxae, 

 then suddenly widened, plain, the hind extremity more 

 or less strongly hooked, the apex being obtusely pointed ; 

 mesosternuiu horizontal, broadly hollowed out in front 

 in form of an open V ; metasternum elongate, its epis- 

 terna sub-parallel, sinuous at the sides ; intercoxal process 

 long, narrowly triangular, the apex pointed ; abdomen 

 6-jointed, the last joint arcuately truncate at each side 

 at the apex, leaving a short broad triangular projection 

 in the centre ; body winged. 



Female : — differs from the male in having the eyes a 

 little less prominent, less approximate above ; the pro- 

 thorax shorter, less globose, broader in front and behind ; 

 the scutellum not sinuous at the sides, and notched be- 

 hind ; the elytra not so parallel, a little expanded behind 

 the middle, the apex pointed (but still having the tooth 

 at the sutural angle, as in the cJ) ; the epipleural fold 

 broadly continued to the hind extremity : the fore and 

 hind thighs straight, less strongly incrassate, simple ; 

 the tibiae (of the same pairs) sinuous, not arched, and 

 neither expanded nor excavated within ; intermediate
