Platyphanes Clarki, n.sp. 



Widely ovate, brilliantly nitid, head metallic green and purple, 

 pronotum and elytra dark olive-bronze, the margins of both and 

 the epipleurse of the latter metallic gold or purple; legs and 

 underside metallic black, the former very, the latter moderately 

 nitid, apical joints of antennae piceous, tarsi and tibiae with 

 golden pubescence. 



Head truncate in front of epistoma, its sides rather straightly 

 widening, with a large foveate impression at each angle, and 

 separated from front by a wide concavity with an arched suture; 

 front convex, the forehead rather sparsely, the clypeal area more 

 thickly dotted with fine but evident punctures; eyes separated 

 by a space equal to the transverse diameter of one eye; antennae 

 robust, not reaching the base of thorax, with joints 8-11 strongly 

 enlarged, 3 little longer than 4, 5-7 gradually widening, 8-10 

 nearly circular, 11 ovoid, larger than 10. Prothorax moderately 

 flat, glabrous, twice as wide as long (5 x 10 mm.), arcuate- 

 emarginate at apex, anterior angles advanced but rounded, 

 sinuate-emarginate at base, with a wide central lobe, and acute 

 posterior angles produced backwards; sides narrowed anteriorly 

 but uniformly rounded, lateral margins widely furrowed, extreme 

 border reflexed and partly continuous on sides of apex; surface 

 very nitid, minutely and sparsely punctate (punctures only visible 

 under a lens). Scutellum transversely triangular, its centre 

 convex, sides depressed. Elytra rapidly widening behind the 

 prothorax, humeral angles subobsolete, middle two-thirds parallel, 

 apex rather abruptly narrowed and unarmed, with uniformly 

 narrow margin throughout, extreme border raised, the channel 

 within of a bright metallic colour; very convex, gibbous in the 

 humeral regions, convexity greatest in front of middle, sutural 

 region depressed behind scutellum, faintly striate-punctate, the 

 striae only perceptible when viewed from the side, with fourteen 

 lines of small punctures becoming obliterated on sides and apex, 

 and very faintly impressed near suture, otherwise distinct and 

 in general placed at a distance nearly equal to that between the 

 striae; intervals scarcely convex, smooth and polished. Abdomen:
