B. OodnadattcB, sp. nov. Nigricans, antennis sordide testaceis 

 apicem versus vix infuscatis, pedibus testaceis, femoribus 

 (prresertim posticis) plus minusve nigricantibus, elytris ad 

 apicem plus minusve distincte rufescentibus ; supra pube 

 nigricanti et albida indeterminate variegatus, subtus cum 

 pygidio sat dense albido-pubescens ; femoribus posticis ante 

 apicem denticulo manifesto sed minuto armatis ; cetera ut 

 B. lyndhurstensis. 

 Maris segmento basali ventrali antice fovea parva ovali leviter 



impresso. 

 Differs from the preceding by its very different colouring, by the 

 presence of an extremely small denticulation on the hind femora 

 and by the very much smaller fovea (which is elongate oval, not 

 circular) on the basal ventral segment of the male. In some 

 examples the elytra are only vaguely reddish at the apex, in 

 others there is an extremely well defined bright red apical spot. 

 In Mr. Lea's tabulation of Bruchi (Joe. cit.) the place of this 

 species is beside diversipes, Lea, from which it differs inter alia 

 by the minute size of the tooth on its hind femora. 

 Central Australia. 



B. diversipes, Lea. I have an example of this species courte- 

 ously sent me by Mr. Lea, and also numerous specimens of the 

 larger insect from W. Australia, which he dubiously identifies 

 with it. I doubt the identity of the two, although I cannot find 

 any good structural character to distinguish them. Unfortunately 

 my specimen of typical diversipes is a female, The basal ventral 

 segment of the male of the larger insect is without any sexual 

 fovea. Perhaps an examination of a male diversipes from N.S. 

 Wales might show a valid distinction on the basal ventral 

 segment. 



B. quoruensis, sp. nov. Niger, antennarum articulis basalibus 4, 

 elytrorum disco apiceque et pedibus (femorum basi et 

 tarsorum apice exceptis) rufo-testaceis ; supra pube albida et 

 testacea vel rufa variegatus : subtus cum pygidio minus dense 

 albido-pubescens ; capite modice elongato, inter oculos 

 longitudinaliter carinato ; oculis sat subtiliter granulatis ; 

 antennis sat elongatis, articulis 5° — 10* robustis leviter 

 serratis ; prothorace transversim trapezoidali, antice minus 

 fortiter angustato, crebre subtiliter ruguloso, elytris sub- 

 tiliter punctulato-striatis, interstitiis planis fere ut pro- 

 thorax asperis sed paullo magis subtiliter ; femoribus 

 posticis dente parvo acuto armatis. 

 Maris segmento basali ventrali nullo modo foveolato. Long.,
