fhen a space sparsely punctured iu front and followed by a 

 third short row of punctures, beyond which are three rows of 

 punctures, the first very short, the external two nearly as long 

 as that nearest the suture ; outside these rows a wide marginal 

 space is finely, obscurely, and sparingly punctulate ; the ex- 

 treme apex of the elytra is rather strongly and closely punc- 

 tured. The pygidium bears some long hairs, and is rather 

 finely and closely wrinkled all over in both sexes. 



The underside is much clothed with long reddish hairs. In 

 both sexes the basal five ventral segments have a little close 

 :and rugose puncturation on the sides, and also a transverse 

 row of punctures running out from the sides towards (but not 

 reaching) the middle, which is smooth. In the male the apical 

 segment is a little shorter than the penultimate, is very widely 

 and scarcely noticeably emarginate at the apex and is finely 

 wrinkled about its base, the apical portion being smooth and 

 separated from the wrinkled part by a transverse deeply im- 

 pressed sinuous line whicb runs from side to side ; in the 

 female the apical segment is rounded behind, and is evenly and 

 coarsely wrinkled, hardly punctulate. The legs are like those 

 of S. suhcsqualis. 



The maxillae, like those of the preceding species, have three 

 strong teeth, of which the intermediate is deeply bifid, and the 

 basal feebl}' trifid. 



The convex parallel form of this insect is suggestive at the 

 first glance of a female Isodon, but the tubercle on the head of 

 both sexes, the strongly punctured prothoracic channel, the 

 mentum strongly emarginate in front with the insertion of the 

 labial palpi invisible from above, and other characters are 

 clearly those of Semanopterus. 



Two specimens were taken by Mr. East at Mallala. 

 B. minor, sp. nov. Brevis ; minus parallelus ; sat convexus; 

 nitidissimus ; piceus ; capite transversim rugato, tuber- 

 culo conico armato ; prothorace canaliculato punctulato ; 

 elytris antice fortiter oblique costatis, interstitiis sub- 

 triseriatim punctulatis. Long. 8 — 8^ L, lat. 4 — ^\ 1. 

 The colour varies from nearly black to reddish pitchy, the 

 underside and femora especially inclining to a reddish colour. 

 The head does not differ much from that of the preceding ; the 

 clypeus is truncate in front, its anterior edge being a little 

 raised, in such fashion that while the truncation is very notice- 

 able if the clypeus be viewed from a point perpendicularly 

 above its surface, from a point behind that (say perpendic- 

 ularly above the scutellum) the eye catches the raised margin 

 and the clypeus appears rounded in front, while viewed from 

 in front of the head the outline of the whole clypeus appears
