tubercles; third with about ten smaller ones, fourth with four 

 larger; fifth and sixth with about nine smaller ones each, those in 

 the sixth being rather the larger; sides granulate. Fifth ventral 

 segment with a small depression at apex. Dimensions : 9. 19 x 

 8 mm. 



Hab.— "Victoria River, Mitchell's Expedition." Type in Macleay 

 Museum. 



This species may be recognised by the rounded prominent 

 tubercles on the elytra, larger than in T. typicus; from this latter 

 species, the presence of clothing will distinguish it; also the 

 granules on the third interstice are more spaced out, and the 

 external rostral ridges are more convergent. On the prothorax, 

 the granules are somewhat peculiarly arranged; along the anterior 

 margin and at the sides, they are small, and irregularly placed; 

 in the centre, there is a group of small granules, with a row of 

 five larger ones on either side, then a bare space containing two 

 large granules. 



Two specimens from Moorilla, (near Young, N.S.W.) differ in 

 being more elongate, and in having the prothorax more finely and 

 evenly granulate; the elytral granules, though somewhat smaller, 

 are prominent, and the clothing dense. They probably represent 

 a variety, or possibly a distinct species.

£. Elongate-elliptical, subdepressed. Black, subnitid; practi- 

 cally without clothing; setae minute, scattered, black; legs with 

 long black setse. 



Head convex, scarcely punctulate, forehead somewhat concave. 

 Rostrum about twice the length of head, and rather narrower, 

 deeply excavate, the external ridges long, prominent, slightly 

 convergent, and extending on to forehead; internal long and 

 convergent, but not meeting; median area depressed, sulciform; 

 lateral basal sulci long and deep. Scrobes deep, open behind, 

 with a short prolongation upwards in front of eye. Eyes small, 

 round. Prothorax(4 x 4*5 mm.) rounded on sides, widest across 

 middle, apex with a slight postorbital sinuosity, no definite lobes
