thorax(5 x 5'5mm.j strongly rounded and dilatate on sides, base 

 slightly narrower than apex, apical margin rounded above, with 

 a feeble postocular sinuosity; collar-impression faintly marked, a 

 feeble transverse impression present in front of base; closely set 

 with small rounded granules, each with a small setigerous punc- 

 ture. Elytra (12 x 7 mm.) widest behind middle, thence gradu- 

 ally narrowed to before apex; apex moderately produced, rounded, 

 feebly mucronate; base gently arcuate, humeral angles prominent 

 laterally, tuberculiform; disc with small fovese in striae, about 

 ten in each to declivity, thence smaller and more punctiform, 

 ridges between foveae well defined though irregular towards base, 

 becoming obsolete and absent on declivity ; interstices with 

 separate granules, sutural costiform at base; second with seven 

 small rounded granules to declivity, thence raised but with the 

 granules barely traceable to apex; third subcostate in basal half, 

 thence with granules distinct but closer than on second; fourth 

 not raised, with five or six more isolated granules; fifth and sixth 

 with more continuous granules, but not costiform; sides foveo- 

 striate, interstices hardly granulate. Apical ventral segment 

 with a shallow depression in middle, intermediate segments 

 flattened in centre. Femora without ridges beneath. Dimen- 

 sions : (J. 18 x 7 mm. 



Hab. — West Australia (Macleay Museum type). 



In its elytral structure, this species approaches to T. acuti- 

 pennis, but, in general build and appearance, it resembles some 

 of the members of the section Costati, the shape of the prothorax 

 and elytra being similar to that of T. Icevicollis. I have seen 

 only a single specimen, but it is so distinct, that I have had no 

 hesitation in describing it.

(j>. Elongate-elliptical, size large. Black, opaque; sparsely 

 clothed with greyish scales; setse small, black. 



Head convex, forehead feebly concave. Rostrum excavate, 

 external ridges glabrous, long, convergent, continued on to fore- 

 head ; internal long, prominent, strongly convergent ; lateral 

 basal sulci long, deep ; median area depressed throughout.
