Head gently convex, continuous with rostrum in same^ 

 plane above, with a few scattered setae. Rostrum short, hardly 

 excavate, save for depression behind apical plate; internal 

 ridges hardly distinct; three impressions traceable at base, a 

 median linear and an oblique somewhat curved foveiform 

 impression on either side. Scrobes simple. Eyes subovate. 

 Prothorax (2'5 x3 mm.) widely and evenly rounded on either 

 side, apical margin with very feeble postocular sinuation ; 

 disc without impressions, granules practically obsolete, some- 

 what more evident at sides, each with a long stout decumbent 

 seta arising posteriorly and projecting backwards. Elytra 

 (6x4 mm.) gently rounded on sides, apex moderately strongly 

 rounded, strongly declivous posteriorly, base almost truncate, 

 humeri very slightly thickened, not projecting; disc with 

 sculpture practically obliterated, no striae traceable, on 

 abrasion small obsolete granules to be seen, rendered slightly 

 evident by the feeble rugosity of derm. Clothed with dense 

 subpubescence and with long stout setae arising from the 

 obsolete granules and traceable into rows according to the in- 

 terstices and into intermediate rows corresponding to the 

 intrastrial granules. Beneath with light scattered setae; inter- 

 mediate segments moderately long; fifth segment lightly con- 

 cave, a deeper transverse sulcus along posterior margin, not 

 reaching sides, but bounded at each end by a small tubercle 

 on the anterior edge. Middle tibiae simple. 



9 . Similar but more robust ; rostrum with median area 

 more definitely impressed; prothorax (3 x 3'5 mm.) and elytra 

 (7x5 mm.) similarly sculptured; beneath convex, inter- 

 mediates longer, fifth with a shallow somewhat irregular fovea 

 surrounded by a few punctures. 



Dim. — S , 9'5 x 4 mm. ; 9 ■> 11x5 mm.

I have had a single 9 °f this species under observation for 

 some time ; the presence of both sexes in the South Australian 

 Museum collection has given me an opportunity of describing 

 it. The clothing of the <$ has been somewhat abraded and 

 apparenty discoloured ; in both females it is of a bright-yellow 

 and in one variegated with grey or white, the prothorax being 

 also feebly trivittate. As seen from above the sculpture 

 appears almost entirely obliterated; viewed from behind, 

 owing to the foreshortening, shallow punctures become evi- 

 dent arranged into longitudinal rows. Of previously described 

 species it comes nearest to T. simplicipes, Lea, but differs in. 

 the sculpture clothing and setae. 



Type in South Australian Museum.
