$ . Black, the upper surface covered with dense brownish- 

 grey scaling, except for a small spot of metallic green on 

 and round the scutellum; the lower parts and the apex of 

 the elytra entirely metallic green, that colour extending up 

 to the 6th stria on the basal half of the elytra, and as far as 

 the 4th on the upper part of the declivity ; the prothorax 

 with a narrow bare central line, and an indistinct broader 

 thinly-scaled, stripe on each side ; legs with grey scales 

 having a coppery reflexion. 



Head with a very shallow transverse impression across the 

 forehead; the central fovea deep and the rostral carina con- 

 tinued distinctly up to it. Rostrum about as long as broad, 

 its sides almost straight and parallel, the space between the 

 scrobe and the eye much longer than the scrobe, the upper 

 surface with the central carina low and bare throughout, 

 the furrows very shallow, the two discal carinae feeble, 

 strongly divergent behind and running almost to the inner 

 margin of the eye, the anterior transverse carina evanescent. 

 Antenna with the joint 2 of the funicle about one-fourth 

 longer than 1. Prothorax as long as its width at the apex, 

 gently convex longitudinally, slightly rounded at the sides, 

 with deep separated punctures and a narrow impunctate 

 central line in the basal half. Elytra with the shoulders 

 reduced and very obliquely rounded ; the punctures in the 

 dorsal striae deep and closely set, but diminishing behind, 

 those in the lateral striae smaller and more widely separated, 

 each puncture containing a minute recumbent seta; a shal- 

 low transverse impression across the base, the intervals 

 almost flat, much broader than the striae, and each w r ith a 

 row of short scale-like recumbent setae. 



The 8th abdominal tergite of the $ with the sculptured 

 dorsal area transversely impressed and bounded in front by 

 a distinct dark carina; the apical excavation very deep, 

 both its upper and lower edges deeply sinuate. The redeagus 

 with a very long narrow cylindrical sac, which in repose is 

 folded twice on itself and is one-third longer than the struts 

 of the median lobe, only the terminal half being closely set 

 with minute spines ; the spiculum is very stout, being nearly
