stoutest ; 8 shorter but not less stout (it is distinctly transverse) ; 



9 and 10 about equally wide, but 10 a little longer (9 transverse, 



10 scarcely so) in the male [in the female 9 is about intermediate 

 in size between 8 and 10, and 5 is not at all dilated]; 11 some- 

 what oval, as long as 9 and 10 together, and in the middle wider 

 than either. 



This species does not seem very near to any other previously 

 described. The discoidal stria of the elytra seems a little less 

 strongly impressed in some specimens than others, but I think 

 this is an accidental variation. 



South Australia ; I have taken it near Adelaide, and also find 

 it among some Adelaide specimens taken by the late Mr. Hart. 

 It occurs among vegetable debris on the banks of streams. 



B. liyahna, Schaufuss. Last November I found a Bryaxis in 

 the Alpine district of Victoria which agrees fairly well with the 

 description of this species so far as it goes, but it is impossible to 

 be scire, as the description is very defective — not mentioning the 

 puncturation of any part, and only casually alluding to the exist- 

 ence of any sculpture on the basal dorsal segment of the hind 

 body. If the insect in question be distinct from B. Iiyalina, I 

 should judge that it is likely to be distinguished by the two 

 oblique striae which run hindward from the front of the basal 

 dorsal segment of the hind body being more strongly diverf>-ent, 

 and by the puncturation being different ; this on the head, pro- 

 thorax, and hind body is fine, somewhat sparse, and inconspicu- 

 ous ; while on the elytra it is much coarser and closer, more so 

 than is usual in (at least the Australian species of) the genus. 

 From B. Jiacijyes, Schauf. (another allied species), the long basal 

 segment of its hind body will distinguish the present insect, which 

 seems to agree with J5.^/frti-i/;e6^ in having the stride of the basal 

 dorsal segment strongly divergent hindward. 



B. inusitata, sp. nov. Nitida ; sat brevis ; sparsim ochraceo- 

 hirsuta ; ferruginea ; antennis minus robustis ; capite sat 

 brevi, antice transversim 3-foveolato, postice utrinque fovea 

 majori instructo ; prothorace transverso hevi, postice foveis 

 3 (transversim positis nee linea conjunctis) instructis ; 

 elytris prothorace vix longioribus, transversis, perspicue 

 punctulatis, humeris subtuberculiformibus, stria suturali 

 profunde impressa discoidali subtilissima ; abdominis se*^*-- 

 mento 1° quam 2"' 3"' que conjuncti sublongiori, basi fortiter 

 transversim sulcato, utrinque juxta sulcum stria longitud- 

 inali instructo. Long., f 1. ; lat., -j%l. (vix). 



The antenufi^ are about ecjual in lengtii to the head and jiro- 

 thorax together. Tlie basal two joints are very similar inter se,
