(J. Elongate-elliptical; size large. Black; densely clothed with 

 light grey subsquamosity; beneath, with greyish-yellow clothing 

 at sides, and with a light golden-brown, median vitta. 



Head not quite in the same plane with rostrum above; the 

 external, rostral ridges continued back to above eyes; median 

 line bare in front, hardly carinate. Rostrum short, rather nar- 

 row across the external ridges, these parallel; median carina dis- 

 tinct; sublateral sulci shallow, deeper at base. Eyes rotundate, 

 Prothorax (5*5 X 6*5 mm.) subdilatate on sides, widest in front of 

 middle; apical margin rounded above, with moderately prominent, 

 ocular lobes. Disc with a moderately distinct, subapical impres- 

 sion; with median and sublateral lines free from granules, hardly 

 impressed: granules variable in size, small, with a few larger ones 

 about subapical impression, and a few near the base, the granules 

 rather distantly placed. Sides sparsely granulate above, and in 

 front. Elytra (12'5 x7'5mm.) subelfiptical, gently rounded on 

 sides; base feebly emarginate. Seriate punctures small, in some- 

 what flexuous lines, distorted by the tubercles; intrastrial gran- 

 ules small, not at all conspicuous; interstices tuberculate, sutural 

 with a few, small, rounded tubercles at base, rapidly deteriorat- 

 ing into widely separated granules, not traceable much beyond
