iufuscate, sliining. Elytra as wide as tlie protborax and about a 

 tbird longer, witb truncate base, and rounded rectangular sboulders, 

 the sides parallel, abruptly inflexed at apex, the apical margins 

 sharply bordered below and forming an obtuse angle with each 

 other when seen from above ; surface pulvinate-convex from base 

 to apex, before the middle subnitid, very finely and apparently 

 confusedly punctate, the seriate and interstitial punctures being 

 similar ; declivity beginning before the middle, somewhat depressed, 

 opaque, without evident striation, very closely and finely granulate, 

 and set with single series of rather long upstanding hairs. Under- 

 side rather darker ; legs brown-testaceous, the tibiaj rounded above 

 and finely seri'ate. 



Hah. Sumatra, from tobacco (Grouvelle). 



A near ally of X. semiojDants, Eiclih., which it closely 

 resembles in colour and sculpture. Jt is a rather smaller 

 insect, and is best distinguished by the much shorter 

 elytra, which are barely one-third longer than the pro- 

 thorax, and present, when viewed from the side, a 

 uniform dorsal curvature from base to tip ; in X. semi- 

 opacus the elytra are rather more than a half longer than 

 the prothorax, and are nearly cylindrical to behind the 

 middle, and not uniformly curved from base to apex. In 

 X. semigranosus the prothorax is longer in proportion to 

 its width, and is less ample before the middle ; the 

 elytral punctuation is finer and the traces of the strias 

 are even more indistinct than in its congener. My 

 type has a short impressed line on the base of the pro- 

 thorax anterior to the scutellum, but this may be an indi- 

 vidual characteristic.

Fem. Oblonga, picea, pedibus antennisque pallide testaceis, 

 parce pilosa ; prothoracc late scmi-elliptico, lateribus postice 

 leniter rotundatis, dorso gibbo, posterius sublaivi ; elytris striato- 

 punctatis, interstitiis uniseriatim setosis, in declivitato obliqua,

FKiiALK. Oblong, piccous (perhaps black when mature), mode- 

 rately shining, scantily hairy, the antennas and legs pale testaceous- 

 yellow. Head subconvex in front, rather sparsely and strongly 

 punctured, with a supraoral shining median elevated space, hairs
