longer than the body, inserted on the head very close to the base 

 of the mandibles; first joint long, slightly curved, gradually 

 thickened towards the apex ; second very short ; third to sixth or 

 seventh subequal, the others gradually diminishing in length, each 

 narrow and cylindrical, slightly thickened at the apex, furnished 

 beneath with some long fine hairs that usually lie flat along a 

 narrow channel but sometimes project and form a delicate fringe, 

 especially near the apex of the joint. Prothorax not longer than 

 broad, slightly constricted and transversely grooved near base and 

 apex, acutely tuberculate at the middle of each side. Mesonotum 

 with'stridulatory area divided by a median line. Scutellum rounded 

 at apex. Elytra elongate, gradually retracted behind. Legs 

 rather long ; femora gradually thickened for about two-thirds of 

 their length from the base, narrowed again towards the apex, the 

 hind pair not reaching to the apex of the elytra ; middle tibiae 

 marked with an oblique notch or groove on the outer face not far 

 from the apex ; first joint of hind tarsus longer than the next two 

 united ; third joint of tarsus cleft almost to the base ; claw-joint 

 long. Front coxae rounded, with their acetabula open posteriorly ; 

 acetabula of middle coxae very narrowly open to the epimera, 

 sometimes closed; episterna of metathorax narrow, gradually 

 attenuated posteriorly.

Body and legs black, the elytra dark metallic green, rather 

 denselv covered with a short greyish-tawny pubescence. Head 

 densely and very finely punctulate, marked on the vertex with a 

 median impressed line which extends 

 forwards to the clypeus, the latter 

 with its front margin raised and 

 arcuate, the ante-clypeus yellow and 

 glossy. Prothorax densely and very 

 finely punctulate, with a few larger 

 punctures scattered here and there ; 

 disc with a faint tubercle on each 

 side just in front of the basal trans- 

 verse groove. Elytra much wider 

 at the base than the base of the 

 prothorax, narrowed backwards from 

 the base, subacuminate at the apex, 

 each ending in a single median spine ; 

 disc of each marked with four or 

 five unequal rows of strong well- 

 separated punctures on the basal 

 half, the side with some similar 

 irregularly scattered punctures. In 

 the male the head is relatively much 

 larger than in the female, the an- 

 tennas nearly twice as long as the body, the legs stouter, with the
