convex, finely striate; third stria more strongly impiessed on 

 apical declivity and joining sutural stria at apex; suljinarginal 

 stria faintly impressed, very near margin. Head dark piceous, 

 labrum testaceous; prothorax piceous brown, lateral margin and 

 middle of base testaceous; elytra testaceous, a very wide dark 

 piceous fascia across disc considerably behind base, apex widely 

 piceous; legs testaceous, antennae infuscate, basal joints testaceous. 



Head depressed, hardly impressed laterally; a feeble oljlique 

 ridge on each side near eyes; clypeal suture finely impressed; 

 clypeus bifoveolate; eyes large, convex. Antennaj filiform, not 

 long. Prothorax transverse (0'65 x 0-85 mm.), w^idest about 

 anterior third, roundly declivous to lateral margin anteriorly; 

 sides strongly rounded to apex, straight posteriorly and hardly 

 narrowed to base; anterior margin truncate; anterior angles not 

 marked; basal angles rectangular, acute; base lightly and roundly 

 produced backwards in middle; lateral border reflexed, reaching 

 to sides of head at apex ; lateral channel wide, nai'rowed to 

 anterior angles; median line deep, a strongly marked arcuate 

 transverse line defining basal part of prothorax; a lightly carinate 

 longitudinal submarginal ridge near each basal angle. Elytra 

 oval, convex, much wider than prothorax (2x1-3 mm.); sides 

 I'ounded; shoulders rounded; five inner stria3 lightly impressed, 

 finely crenulate, sixth and seventh obsolete; interstices depressed, 

 first narrow on apical declivity, second and third ampliate on 

 apical declivity, third with two small setigerous punctures — the 

 anterior just before, the posterior just behind discoidal piceous 

 fascia; lateral interstice very narrow, not convex, having four 

 -setigerous punctures behind shoulders and about same number 

 towards apex; base not bordered; lateral Ijorder narrow, reflexed, 

 forming a very slight prominence at humeral angles. Anterior
