of tlie surface. The silky pubescence of tlie elytra is so 

 arranged as to present the a|)pcarance of numerous brighter 

 and less bright areas varying in lustre with the direction iu 

 vliicli the light falls upon them. The antennai of the male 

 are about three times as long as the body ; the first joint and 

 the third are transversely rugulose, the third joint has at the 

 apex an abrupt ring-like thickening which ])rojccts rather 

 more on the outer side ; the fourth and fifth joints are also 

 slightly thickened at the apex ; each of the joints from the 

 fifth to the eighth is furnished with a small acute spine at the 

 outer apex, and each from the sixth to the tenth is denticu- 

 lately produced at the inner apex ; the third joint is slightly 

 longer, the fourth a little shorter, than the first ; the fiftli is 

 distinctly longer than the third.

Ilah. Paungdd, in Burma [G. Q. Corhett). 



Prothorax strongly enough rounded at the sides in the 

 middle, narrowed at the base and apex ; the disk with two 

 very distinct longitudinal grooves which cut off a median, 

 somewhat oblong, and s])arsely punctured area from two 

 lateral plagre, each of which is traversed longitudinally by 

 three or four narrower and less distinct grooves, the intervals 

 between which are narrow and cariniform, the sides below 

 these areas are intricately and not strongly rugose. The 

 elytra bear punctures of two kinds — larger and less closely 

 crowded punctures from which the suberect fulvous setae 

 spring, and minute closely crowded punctures occupying 

 the intervals and giving rise to the finer hairs of the laid 

 pubescence. 



This species is to be recognized by the peculiar sculpturing 

 of the prothorax.
