montanus the coarse, close-set elytral punctures cau always be clearly seen, the 

 pronotum is much less uneven, though the elytra have some apical tubercles not 

 mentioned by the autlior. C. fascicularis, inter alia, has a much narrower, 

 straight-sided, flatter prothorax, depressed in middle, the elytral costae more re- 

 gular. Type in Coll. Cai-ter. {N.B. — Pascoe's description of the antennae of JO. 

 fascicularis "basal joint longest, the rest to the tenth subeiiual" is inaccurate. In 

 my example, besides the basal joint being long, both the 2nd and 3rd joints are 

 clearly longer than succeeding joints. 



Cestrinus dentatus, n. sp. 



Elongate, parallel, subnitid black, tarsi red. 



Head and pronotum coarsely but not confluently punctate, the intervals be- 

 tween punctures themselves very iinely punctate; 3rd joint of antennae not as 

 long as 4th-5th combined, joints beyond 6th wanting. 



Prothorax areuate-emarginate at apex, truncate at base, anterior angles acute 

 (less sharply than in C. trivialis Erich.) ; sides rather widely and evenly rounded, 

 and clearly sinuate before the dentate, rectangular hind angles; margins sharply 

 and closely crenulated. 



ScwUellum oval. 



Elytra wider than prothorax at base, shoulders rather square, sides jsarallel ; 

 striate punctate, the punctures in striae large, round, uniform in size and separated 

 by narrowly-raised eancellate ridges, intervals convex, finely and sparsely j^ustu- 

 lose, a few very short pale hairs distinguishable at sides and apex; sternum 

 coarsely, abdomen finely punctate. Dimensions : 11 x 4 mm. 



Hab. — Camooweal, North Queensland. 



A single specimen, given me by my friend Dr. E. \V. Ferguson, is quite 

 distinct from C. trivialis Erichs. (perhaps the most widely distributed Tenebrionid 

 in Australia). After Mr. K. G. Blair's wholesome treatment of the species of 

 this genus (these Proc, xliv., 1910, pp. 529-532) it is a daring venture to describe 

 another Cestrinus; nevertheless, the above is clearly differentiated from Erich- 

 son's species by (1) the differently shaped prothorax and especially in the small 

 posterior tooth, (2) the difference in sculpture, the punctures of the upper sur- 

 face being coarser, of the lower surface finer than in trivialis, while in both cases 

 they are clearly more widely separated. The pustules on the elytra are much 

 finer and more sparee. Type in Coll. Carter. 



(N.B. — r. championi Blackb. is, I consider, quite distinct from trivialis, not 

 only in size, but in the system of pronotal punctures, whicii are not confluent, as 

 in trivialis, though less widely separated than in dentatus. It is much more 

 strongly bristled than dentatus with a differently shaped prothorax and less crenu- 

 late margins ) . 



GOXOCEPHALUM SUB-C»STATUM, n, Sp. 



Ovate, brownish-black, opacjue. rather thickly covered with short, bristly 

 hair. 



Head: labrum prominent, clypeus sub-truncate with 4 coarse setae thereon 

 and at sides forming an angle with the raised canthus; surface coarsely, densely 

 punctate; antennae with 3rd joint as long as the next three combined, 4th-inth 

 moniliform, 11th large and ovate, twice as long as 10th. 



Prothorax areuate-emarginate at apex, truncate at base, anterior angles 

 acutely produced, sides widely rounded, widest at middle, sinuate behind, pos-
