round, tubercles on the disk somewhat squamose, and of the same 

 shape as in T. fascicularis and T. nasutus; scutehum not short, 

 ogival ; elytra sub-parallel and having on each side, in addition to 

 the raised sutural part, four carinate costae bearing series of equi- 

 distant, short fascicles of setas, and much more raised than the 

 alternate costse which are not sharply carinate and bear no 

 fascicles, the intervals are filled with a series of broad, some- 

 what deep, round punctures, and the outer margins are densely 

 ciliate, and not serrulate ; prosternum with a transverse, nodose 

 projection ; apical teeth of anterior tibiae very distinct, the basal 

 tooth is sub-median and sharp and followed as far as the elbow 

 by strong, sharp, serrate teeth ; intermediate and posterior tibiae 

 serrate. 



Length 7-8 mm. ; width 4f-5^ mm. 



Eesembles somewdiat rubbed examples of T. fascicularis, but is 

 easily distinguished by the quadrangular, serrate posterior tibiae ; the 

 shape of the genital armature is also different.

Black, moderately shining, elongate ; clypeus acuminate, frontal 

 part with two transverse, parallel, slightly arcuate, briefly pubescent 

 carinae united in the centre by a longitudinal one ; head rugose, 

 fringed with flavescent hairs ; basal joint of antennae fuscous, the 

 others i"ufescent with the club flavou.s ; prothorax closely but not 

 deeply pitted, strongly serrate laterally and fringed with flavescent, 

 closely set fascicles of hairs, convex, broadly grooved longitudinally 

 in the middle, but with the groove much more shallow in the centre 

 than at the base or in the anterior part, on each side of the base 

 there is an elongate tubercle, and a supra-lateral one longer but 

 divided into two, these tubercles and also the rounded walls have 

 some short flavescent hairs, the outer angles of the base are sharp ; 

 scutellum elongate, ogival, deeply impressed at base ; elytra elongate, 

 one-third longer than broad, fringed along the base and the outer 

 margins, which are not serrate, with a dense, very short, light, 

 fulvous pubescence, and having on each side ten rows of tubercles
