Black, without any markings except a narrow abbreviated marginal white line 



behind the middle, and with remotely scattered minute white scales, every granule 



bearing a recumbent white scale-like seta; the central part of the mesosternum 



apparently clothed with long pale brown hairs, but these are really long erect scales 



which are split for the greater part of their length into a number of hair-like 



divisions; the centre of the metasternum with shortly-fringed erect brownish scales, 



the side-pieces of the meso- and meta-sternum with dense recumbent rounded 



brownish scales. 



Head with distinct scattered punctures in front, almost impunctate on the vertex, 

 the forehead without a furrow or fovea. Rostrum with tw^o flat carinae on each side 

 at the base, the central carina almost obliterated by punctures. Antennce as in

 regularly rounded and not flattened, the apical constriction is shallower, and the setfe 

 are white. Elytra narrow (6x3f mm.) and very sharply acuminate behind, the apex 

 extending 1 mm. beyond the end of the abdomen and not produced downwards, the 

 whole surface fairly closely and irregularly granulate and without lateral striation,
