Hab. — Victoria : Emerald, in damp places (National Museum 

 ex E. Jarvis). 



In general appearance rather close to B. tibialis, but larger 

 and stouter, head not quite the same, dorsal striae much shorter, 

 tibife simple, etc. The head is somewhat as in B. bimucronatiis , 

 but the prothorax is without the conspicuous median channel of 

 that species. 



The pubescence is rather long, but on the two specimens before 

 me there are no long hairs scattered about. The medio-basal 

 impression on the prothorax from some directions a|ipears in the 

 form of a narrow deep isolated line, from others it appears fairl}' 

 large and rounded, with a feeble subtubercular elevation on each 

 side of it, the tubercles being quite distinct from the sides; the 

 lateral impressions from some directions appear rather deep, but 

 from others each appears as an almost rounded and isolated fovea. 



E u P I N K s . 



The males of this genus usually have very distinctive features 

 in the metasternum and abdomen, and often in the legs and 

 antennae, but the females seldom jiossess such. I think that no 

 species of the genus should be described from the female only, 

 although this has been done in many instances, with the proba- 

 bility of causing confusion. 



It is not always easy to mount single and small (such as all 

 species of this genus are) specimens, so that both the under and 

 upper surfaces can be examined, but it is absolutely necessary to 

 do this in Eu2nnes, as many species strikingly alike on the upper 

 surface, even in such an abnormal feature as a strongly inflated 

 fifth antennal joint, are quite readily distinguished by the meta- 

 sternum and abdomen. The front trochanters of the males are 

 also frequently armed, but the armature is not always easy to 

 see, even on specimens mounted on their backs. The second 

 abdominal segment appears to be the first, the true first nearly 

 always being almost or quite concealed. 



Of some of the species of which only the male is here described, 

 I probably have the female, but not being certain that they are 

 correctly mated, I refrain from describing the latter sex
