line present; evenly and closely set with small, rounded, de- 

 pressed granules, each bearing a long stout decumbent seta. 

 Elytra (13 x 8*5 mm.) elongate-ovate, apex abruptly rounded, base 

 subtruncate, humeral angles rounded. Disc with three broad 

 striae on each elytron, not foveate, but with a double row of 

 obsolete cross- reticulations separated in middle by an obsolete 

 intermediate interstice; interstices prominent, costate, each with 

 a row of decumbent setae along upper and inner aspect. Sides 

 striate, each stria with a row of granules; interstices broad, 

 setigero-granulate. Intermediates long; fifth segment large, with 

 a deep median excavation, bounded on either side by a projection 

 covered with long yellow hair; apical tergite likewise clothed. 

 Legs short, tibiae not longer than femora, thick; posterior tibiae 

 fringed on inner side. Dimensions : (J. 19 x 8-5 mm. 



The above description is taken from a large unabraded male in 

 my own collection. 



Type,£.(Macleay Museum). Size smaller; setae yellowish-red; 

 clothing abraded, more feebly maculate and absent beneath; pro- 

 thorax (5x6 mm.) with feebler impressions; elytra (12 x 8 mm.) 

 with interstices more noticeably granulate and less costiform; 

 seta smaller and situated nearer top of costa, intermediate inter- 

 stices obsolete, striae with cross-reticulations definitely granuli- 

 form. Dimensions : £.18 x 8 mm.

 the rostrum, prothorax, and legs would be quite sufficient to 

 justify forming this and T. Rayneri into a new genus.

Q. Of the size and with the appearance of T. ambiguus. Black, 

 practically without clothing; setae light yellow. 



Head and prothorax (5 x 6*5 mm.) as in typical specimens. 

 Elytra (13 x 8 mm.) with intermediate interstices not obsolete, 

 but interruptedly setigero-granulate "in single series, fourth with 

 only a few granules; interstices, one, three, five, and seven, pro-
