longitudinally ; anterior margin strongly sinuate, middle rounded 

 and projecting very lightly above head ; base truncate ; granules 

 closely placed, round, unequal, separate, unisetigerous, extending 

 on sides to near cox». Elytra ovate (11 x 71 mm.), rounded on 

 sides, dilatate behind middle, decidedly narrowed to shoulders, 

 very strongly and rounded declivous behind ; convex towards 

 each side, Hghtly convex longitudinally; disc depressed along 

 suture; base lightly emarginate ; the shoulders advanced in a 

 strong truncate tuberculiform projection; apex wide, without 

 sinuosity or projections near suture ; strioe uneven at bottom, 

 having along their course very small setigerous granules between 

 the granules of the interstices ; dorsal interstices closely set for 

 whole length with strong, separate, unisetigerous granules becom- 

 ing conical and tuberculiform on posterior declivity ; granules of 

 first interstice small, round, evenly placed ; third and fifth inter- 

 stices with the granules forming a double row in. places. Meta- 

 sternum convex, much raised above the plane of the first ventral 

 segment. First ventral segment very lightly, widely, and flatly 

 hollowed between cox» ; second Hat ; second, third, and fourtli 

 with a very light oblique impression on eaeli side; apical segment 

 longer than two preceding ones together, deeply excavate : the 

 excavation parallel sided, rounded at bottom, extending for 

 whole length of segment; a short pointed tuft of bristles placed

i'^fimflZe.— Differing from male in its broader, heavier, and flatter 

 form ; prothorax less dilatate on sides, less convex (5x6 mm.) ; 

 elytra much more depressed, less roundly and strongly declivous 

 behind (12 J- x 8 J- mm.), the apex narrower ; granules of interstices 

 weaker, less conical, those of third and fifth placed ^ more 

 evidently in a double row. The under-surface diflering in the 

 yellowish scales being absent from the middle of the first two 

 ventral segments, and more thinly-set on the middle of the last 

 three ; first segment not hollowed in middle ; second longer and 

 convex ; second, third, and fourth without lateral impressions ; 

 apical segment with a small round median impression.

Habitat.— 'Westward to Everard Range, S.A. May .June, 1891. 



Compared with T. aqualis, SL, this species differs by the elytra 



strongly rounded on the sides and convex longitudinally ; their 



sculpture more regular, the granules of thi; interstices being more 



even and more conical. 



From T. Ifelmsi, SI., it may be distinguished by its less convex 

 forna ; and wider elytra, more dilatate on the sides, with the
