162 AUSTRALIAN PSELAPHID.E, 



before the base; the carinules of the first dorsal segment are 

 longer and more approximate. 



I have two specimens from Swan River which are much 

 darker, with a fine but subrugose punctuation on the elytra. I 

 do not think that they can be considered as a distinct species. 



Genus Beiara, Reitter.

This genus is closely allied to both Rhybaxis and Eupines, and 

 differs from them in the. following points : the body is more 

 elongate and more parallel, the prothorax bears only two lateral 

 fovea?, the median one is wanting, the elytra have a decided 

 dorsal stria, the first doisal segment is large and bears two 

 approximate and parallel carinules, the mesosternum is strongly 

 carinate between the intermediate coxa?, which are not quite 

 approximate; the first antennal joint is always longer than the 

 second one, more especially in the male in which it is more or 

 less irregular and toothed, in the male sex the forehead and 

 epistoma are more or less produced and armed. 



This genus is peculiar to Australia. 



The name of Gonatocerus, Schfs., being preoccupied, has been 

 changed by Reitter to Briara. 



There has been some confusion of species by Dr. Schaufuss. 

 What he describes as a new species under the name of B. com- 

 munis, is nothing else but Bryaxis hasalis, King; and the species 

 considered by Schaufuss as being B. basalts, King, is a different 

 one altogether, which I name capitata. So that the synonymy is 

 as follows : — 



B. basalis, King = communis, Schfs. 



B. capitata, Raffr. = basalis%, Schfs., nee King. 



Briara basalis, King.
