Considerably larger than any of the other Indian species except 



T. hennigi, from which it differs in 

 being a little larger and stouter, and 

 in having the pronotum wider in the 

 middle ; labrum reddish testaceous ; 

 head large, vertex broad, frontal 

 sulci deep, slightly convergent 

 towards base and terminating in a 

 distinct transverse impression, so 

 that the portion between the sulci 

 appears raised and subquadrangular, 

 orbital striae rather distinct ; pro- 

 notum broad, very short and trans- 

 verse, the central portion being about 

 twice as broad as long, very strongly 

 rounded at the sides, strongly con- 

 stricted in front and behind ; elytra 

 dark, with the basal portion irregu- 

 larly testaceous, the raised callosities

 behind the middle, not quite touching the suture ; the apex is 

 whitish testaceous ; punctuation rather strong towards base, and

 large punctures), feeble in middle, obsolete towards apex ; legs
