interstice. Clear ferruginous red, subtestaceous above apical 

 declivity of elytra; legs testaceous; antennae ferruginous, basal 

 joint testaceous. 



Head convex; front widely but rather deeply bi-impressed; 

 eyes large, convex. Antennae short, stout, filiform (reaching back 

 a little behind base of prothorax). Prothorax broader than long, 

 widest a little before anterior third, evidently narrower across 

 base than apex; disc lightly convex, rather depressed in middle, 

 lightly declivous to basal area; sides strongly rounded anterioi'ly, 

 shortly, strongly and roundly narrowed to anterior angles, strongly 

 sinuate posteriorly, meeting base at right angles; anterior margin 

 truncate; anterior angles not marked; base widely truncate in 

 middle, oblique on each side; basal angles prominent, acute; basal 

 area depressed, well marked, extending to lateral border at each 

 side, defined anteriorly by a strongly marked transverse punctate 

 impression; lateral border very narrow on rounded part of sides, 

 thick and strongly reflexed near basal angles; median line very 

 lightly impressed on disc; four or five setigerous marginal 

 punctures between anterior third and anterior angles. Elytra 

 widely ovate; base roundly truncate; humeral angles not marked; 

 sides rounded; first stria entire, punctate for more than half its 

 length, simple posteriorly; strite 2-5 consisting of rows of closely 

 set strong punctures extending from base to lighter-coloured 

 laevigate apical part of elytra ; submarginal stria punctate ; 

 lateral interstice not convex; marginal channel closely punctate; 

 the punctures from shoulder to apical curve each bearing a long 

 seta. 



Length 2-25, breadth 1 mm.

Allied to T. monochrous, Schaum. but differing by its shorter, 

 wider, and rather less convex form; the prothorax wider, more 

 strongly narrowed to base, disc flatter and less strongly declivous 

 to base, margin plurisetose behind anterior angles; elytra shorter, 

 wider, less convex, five- (not six-) striate.
