Belongs to Eaffray's Grroup IX, and allied to T. hispiim Raffr. 

 and T. squamosus Raffr., from Sumatra ; but readily distinguished by 

 its much smaller size, and by the shape of the maxillary palpi. For 

 Raffray's Table, see Ann. Soc. Ent. Fr., 1904, p. 377.

 9 larger, about as long as broad, slightly obconical ; 10 a little larger, obconical ; 

 11 more than twice as long as 10, sub-ovate, acuminate at apex, and from apex

 curved, broadening to apex ; 3 shorter, obconical ; 4 a little longer, fusiform. 

 Prothorax longer and very little broader than head, sub-cordate, convex ; a

 posterior side of sulcus in middle another fovea. Elytra sub-quadrate, very 

 little longer, but much broader, than prothorax, slightly broader than long, 

 somewhat attenuate anteriorly ; two foveae at base ; sutural stria well
