246 Eustace W. Feigiisou : 



Head contimious in pi-otile with the rosti-um ; forehead feebly 

 flattened. Itostrnni moderately deeply exeavute; external ridges 

 subparallel; internal I'idges prominent, long, slightly convergent, 

 not meeting; median area moderately deeply depressed, narrow, 

 fiulciform; sublateral sulci long, moderately deep. Scrobes open 

 posteriorly. Eyes large, ovate. Antennal scape moderately long. 

 Prothorax (3.75 x 4 mm.) little wider than long, rather feebly 

 rounded on sides; apical margin rounded above, with moderately 

 marked postocular emargination, but with lobes indefinite; trans- 

 verse subapical impression well marked, median impression feeble, 

 more marked posteriorly. Disc rather closely set with small round 

 granules, smallest about centre, larger along subapical impression ; 

 sides also granulate. Elytra (11 x 6 mm.) elongate, at base as 

 wide as prothorax, gently widened from base backwards; ]>ase 

 gently emarginate, humeri very slightly produced. Disc with punc- 

 tures indefinable, but with intrastrial granules distinct, often con- 

 fused with the interstitial tubercles; interstices with small tubercles, 

 for the most part hardly larger than granules; second with about 

 eight isolated ones, small at base; becoming larger posteriorly, one 

 or two being on declivity; third with small granuliform tubercles, 

 irregularly arranged in double series from base to middle, thence 

 in single series, tubercles not reaching to apex; fourth with one or 

 two small tubercles about middle; fifth with tubercles similar to 

 third but inconstant in arrangement, basal tubercles generally in 

 double series; sixth with a single row of from six to ten small 

 tubercles, not extending to base or apex. Sides with interstitial 

 granules in single series. Beneath flat; intermediate segments 

 long; fifth segment with a feeble subquadrate impression, with a 

 small tubercle on either side near apex, partly obscured by setae. 



^ Rather more ovate than $ ; elytral sculpture similar, but even 

 more confused; beneath gently convex, fifth segment without im- 

 pression. 



Dimensions. — ^ 17 x 6 mm. ; ? 17 x 6.5 mm. 



Hah. — Victoria, Portland (J. E. Dixon, also from National 

 Museum and British Museum). 



Of this interesting species, I have recently received 26 specimens, 

 from J. E. Dixon, of Melbourne. Though I believe it to belong to 

 the tuberculate section of the genus, the tubercles are so fine as to 

 be mere granules. It is most nearly allied to T. a?igustus, also a 

 Victorian species, and the elytra! tubercles are fine in both species, 

 but the differences in arrangement, and especially the conspicuous
