$. Size moderately large, elongate, robust. Black; practically 

 without clothing above ; with, yellow pubescence clothing the sides 

 of the prothorax, the basal portion of the sides of the elytra, and 

 the sternal segments; median vitta ochreous-yellow ; legs sparsely 

 clothed with yellow ; setae black. 



Head convex. Rostrum little excavate; external ridges sub- 

 parallel; median carina moderately prominent, a deep puncture 

 present at junction with head; sublateral sulci shallow, with a 

 deep basal fovea. Protborax(5-5 x 6-5 mm.) subangulate, dilatate 

 on sides, widest in front of middle; ocular lobes moderately large; 

 subapical impression moderately strongly marked, median line 

 shallowly impressed ; set with low, semicontiuent granules, almost 

 or completely obsolete in centre, more rounded and distinct at 

 lateral angles; sides non-granulate. Elytra (11x7 mm.) not 

 greatly widened posteriorly; base gently emarginate, humeral 

 angles rather strongly marked, out-turned; w4th regular rows of 

 moderately large, open, foveiform impressions, the intrastrial 

 granules feeble; interstices costiform, the first, third, fifth, and 

 sixth strongly raised ; the second and fourth less strongly or not at 

 all raised; third interstice the most strongly raised, somewhat cre- 

 nulate on upper surface, showing a tendency to split up into elong- 

 ated tubercles posteriorly; fifth crenulate-costate, sometimes split 

 into its component tubercles ; sixth composed of elongate, closely set 

 tubercles ; lateral interstices with tubercles obsolete. Undersurf ace 

 with basal, ventral segments flattened or feebly depressed in 

 middle, the other segments gently convex from side to side.
