 finer behind. 

 A. Size larger; sculpture of elytra 

 less strong and less confluent in 



the middle meUyi, Chaud.. p. 280. 



J3. Size smaller ; sculpture of elytra

Black, comparatively dull ; labrum large, black, with the side 

 teeth well marked ; head rather shallowly 

 excavate between the eyes, with the centra! 

 portion rather convex, the striae at the sides 

 of the eyes not strongly marked, and with 

 no distinct furrow at the base of the exca- 

 vation, this being replaced by two shallow 

 fovese ; pronotum long, parallel-sided, nar- 

 rowed and strongly constricted at base and 

 apex, with a central line and indistinct trans- 

 verse striation ; scutellum large, smooth ; 

 e]ytra narrowed towards base, widened be- 

 hind, widest behind middle, and gradually 

 narrowed to apex, closely evenly and strongly 

 sculptured, but not rugose; the punctures 

 are more or less triangular, and give the 

 surface a scabrous or shagreened appear- 

 ance ; legs long, black ; underside almost

 coriacea (nat. size). There appears to be very little difference 

 externally between the sexes ; the single 

 male I have seen is rather smaller, on an average, than the 

 females, and has the elytra somewhat less narrowed at the apex. 

 Length 21-25 millim.

This species is intermediate between T. coriacea and T. granu- 

 lifera, although much more closely allied to the former, which it 

 resembles in general form and in the peculiar sculpture of the 

 elytra; in the reddish colour of the margin of the labrum and 

 part of the legs, and in the sculpture of the head and pronotum, 

 as well as in its generally larger size it resembles T. granulifera • 

 as in this species it has the suture of the elytra more or less
