 Ad ina cordi folia. ATbizzia cimara, Holoptelea integri folia,, Mangifera 

 indica, Shorea robvsta, Terminalia bialata. Terrmnalia myriocarpa, 

 and Grewia tiliaefolia. They also stated that this species has been

Body elongate. Black to reddish brown, elytra usually more reddish, 

 the antennae, palpi, and tarsi brownish yellow. 



Head unarmed but declivous along anterior margin, densely, finely 

 granulose and sparsely clothed with long, erect, inconspicuous hairs 

 on front, with long. fine, longitudinal, parallel costae on occiput; 

 clypeus fiat, densely, finely granulose. with a vague, transverse, sinuate 

 carina near anterior margin extending on each side to tooth at base of 

 labrnm : elypeal suture distinct : labrum finely, densely punctate. An- 

 tennal club not flabellate. but segments strongly transverse, densely 

 clothed with very short, recumbent, yellowish hair-: first segment of 

 club subtriangular. twice as wide as long : second slightly wider than 

 first, not as wide as length of first seven segments united: third oblong. 



Pronotum slightly wider than long, widest at middle ; sides broadly 

 rounded, more strongly converging anteriorly, with a small, unciform 

 tooth at apical angles; posterior angles broadly rounded; surface 

 rather densely, irregularly clothed with whitish hairs, which are short 

 and recumbent on basal half, much longer and erect near anterior 

 margin, rather sparsely, finely granulose on basal half, densely granu- 

 lose and irregularly dentate on apical half, the teeth broad, semierect. 

 variable in size, and rasplike, with three or four larger ones on each 

 side along lateral margin. Scutellum quadrate. 



Elytra at base subequal in width to pronotum at middle; sides 

 nearly parallel, conjointly broadly rounded at apices: submarginal 

 carina following outline of lateral margin, sharply elevated along 

 apical declivity; surface rather densely clothed with short, recumbent, 

 yellowish hairs, densely, coarsely, irregularly punctate, the punctures 

 more or less confluent on apical declivity : apical declivity arcuately 

 deflexed. not margined anteriorly, each elytron with a small, trans- 

 verse gibbosity near lateral margin, and a long, erect, conical tubercle 

 near middle of declivity, the tubercle rugose, finely pubescent, obtuse 

 at apex, placed some distance from sutural margin but connected to 

 it by a vague, transverse carina: sutural margin- feebly, broadly 

 elevated and finely dentate on apical declivity. 



Body beneath finely, densely punctate, densely clothed with long, 

 recumbent and erect, yellowish-white hairs; last visible abdominal 

 sternite broadly rounded or subtruncate at apex. 



Length 5-6 mm., width 2-2.5 mm.
