350 REVISION OF THE AMYCTERIDES, ii., 



interstices elongate, flattened, second with five, third with ten, 

 fourth with none, fifth with ten, sixth with seven, seventh with 

 about ten, almost completely on side, the tubercles very little 

 prominent, sides with interstices similar. Dimensions'. 9-23'5 x 9; 

 prothorax, 5x6; elytra, 16x9 mm. 



Hab. - Queensland. Types in Australian Museum. 



I have placed this species in the typicns-grou^, but it does not 

 seem greatly at home there; the internal rostral ridges almost 

 obsolete would indicate an approach to the bucephalus-group; 

 probably it will be necessary later to propose an intermediate 

 group to receive this species, T. tumulosus and possibly T. 

 sobrinus.

 xii., 1873, p.10. 



Size large, ovate, robust, convex. Black, granules nitid, 

 covered with ferruginous scales except on granules, ventral seg- 

 ments feebly maculate. 



Head large, convex, external ridges continued on up head as 

 two prominent carinse, a median carina also present. Rostrum 

 short but longer than head, deeply excavate; external ridges 

 prominent, subparallel; internal ridges short, distinct, but much 

 less prominent, convergent ; median area narrow, depressed, 

 lateral basal sulci deep, meeting behind internal ridges and 

 extending into concavity of forehead. Scrobes open posteriorly, 

 with a feeble posterior prolongation in front of eye. Eyes sub- 

 rotundate. Prothorax(5*5 x 7 mm.), dilatate, subangulate, apex 

 rounded above, ocular lobes feeble; disc with feeble impressions 

 near and in front of lateral angles, granules round, discrete, dis- 

 tantly placed, larger on disc but more thickly grouped at lateral 

 angles, the centre and lateral depressions almost without granules; 

 sides with smaller granules. Elytra (16 x 10 mm.) elongate- 

 ovate, strongly convex, gently declivous posteriorly, apex sharply 

 mucronate, base emarginate, humeral angles tuberculiform, 

 tubercles projecting laterally. Disc granulate in six rows, 

 sutural with about twenty small granules evenly placed, becoming
