9. (Type in Macleay Collection). More ovate than male; head, 

 rostrum, and prothorax (4x5 mm.) similar. Elytra (8x6 mm.) 

 shorter, more ovate; base truncate; with somewhat irregular rows 

 of punctures, each subtended by a small granule; second inter- 

 stice with three or four tubercles, third with eight, basally 

 rounded, conical towards apex, extending on to declivity; fourth 

 with two near middle; fifth with eight, regular, less acute than 

 in the male, not reaching to apex. Sides with interstices feebly 

 granulate. Beneath, convex, intermediates long; with whitish 

 scales, forming a feeble macule on each segment, and dispersed 

 over the apical one; fifth segment without impressions. Dimen- 

 sions : $. 145 x 6-5; 9. 13 x 6 mm.

( J. In general shape and appearance as in typical specimens, 

 elytra with white clothing more pronounced. Head, rostrum, 

 and prothorax (4.x 5 mm.) as in T. incanescens. Elytra (8*5 x 6 

 mm.) with the striae more regular, the granules accompanying 

 punctures not recognisable as such; interstices tuberculate, second 

 generally with two, sometimes without, tubercles; third and fifth 

 strongly tuberculate throughout, fourth without tubercles. Other- 

 wise as in typical specimens. Dimensions : (J. 14 x 6 mm.

Close to T. incanescens, of which I regard it only as a variety. 

 The chief distinction seems to lie in the strial punctures and the 

 accompanying granules. 



Of this species and the variety, I have had under examination 

 the following : (l)type of T. incanescens Macl., (J); (2)cotypes of 

 T. encaustus Pasc; (3) type of T. muricatus Macl.; (4)cotypes of 

 T. Macleayi Pasc; (o)other specimens in the Australian Museum, 

 Lea's and my own collections. T. incanescens and T. encaustus 

 appear to have been founded on female specimens; T. muricatus 

 and T. Macleayi on males. I formerly regarded the differences 

 observable in the elytral striae as sexual, and grouped these four 

 as one; recently, however, more critical examination of a male of
