EOTHKTDEEES. 



jB. variahiJls, sp. nov. Subopacus (elytrorum interstitiis alter- 

 nis exceptis) ; niger, antennis tarsisque rufopiceis ; pro- 

 thorace transverso longitudinaliter corrugato, postice 

 linea curyata impresso, lateribus augulatis ; elytris 

 postice rotundato-truncatis, apice x^roductis. Loug. 1 — 3 1. 

 Tar. Colore piceo vel testaceo. 

 The thorax is gently transverse, tlie front margin strongly 

 bisinuate and in the middle elevated, the anterior angles pro- 

 duced and acute ; the outline of the lateral margins is very 

 peculiar — from the apex of the anterior angles it is convex for 

 a fifth part of its length, then it is slightly concave to just 

 behind the middle where it is of the same width as at the com- 

 mencement of the concavity, and at that point it is angulated 

 and thence proceeds with a slightly concave curve to the base 

 in such fashion that from the angle the thorax is gently con- 

 tracted backwards. There is a slight vague depression on the 

 front part of the disc and a little in front of the base there is 

 a clearly cut arched line (its convex side turned towards the 

 base) from which two fine lines run backward to the base. The 

 elytra are strongly striated, the stria3 rather indistinctly punc- 

 tured. The alternate interstices are slightly shining, the 

 third roundly convex — the fifth and seventh strongly, the ninth 

 feebly, carinated. The interstices are devoid of distinct punc- 

 turation. The apex of each elytron is rather strongly produced 

 (so that the hinder part of the lateral margin is deeply sinuate) 

 and roundly truncated. 



I know few insects more variable than this in respect both 

 of size and color. It is widely distributed in South Australia 

 and common. I have taken it also in Western Victoria. It 

 occurs under the bark of Eucalypti. 



I am not acquainted with B. illusus, Newm., and on that 

 account should have hesitated to describe this species as new 

 were it not that Mr. Pascoe (Journal of Ent., I., p. 465) in 

 distinguishing his B. equinus from Newman's insect implies that 

 the latter is totally unlike my B. variabilis. 



B.Uhialis, sp. nov. Sat nitidus ; piceo-brunneus ; prothorace 

 subcordato leviter transverso, sat fortiter crebrius punc- 

 tulato, punctis longitudinaliter confluentibus, latitudine 

 majori antice posita, lateribus rotundatis, impressione 

 obscura postice posita ; elytris striatis, interstitiis punctu- 

 latis, his alternatim elevatis ; tibiis fortiter dilatatis. Long. 

 1-21 1. 



Yar. Colore plus minus ve rufo. 

 The thorax is widest immediately behind the anterior margin 



whence it narrows with a curved outline nearlv to the base •
