a wide triangnlar explanate process about posterior third, tliis 

 process lightly reflexed and obtuse at apex; border extending 

 obliquely downwards from humeral angles and almost meeting 

 border of infle-xed margins at lateral processes. Posterior tro- 

 chanters curdiform, not long; apex a little curved inwards, 

 obtusely pointed : intermediate femora wide towards apex, armed 

 on inner edge of lower side a little before apex with a long curved 

 spur-like process;"^' posterior elongate, not swollen in middle : 

 anterior tibiaj thick, bent; upper side widely sinuate in middle; 

 lower side with a strongly raised, wide, obtuse protuberance 

 opposite middle of sinuosity of upper side. Length 32, breadth 

 8 "6 mm.

In many ways, this species and the following are the most 

 singular Carabs I have seen, and are very different f rom ' ^. 

 calcaratuin Macl., by the explanate lateral processes of the elytra. 

 In B. macleayi the lateral processes of the elytra project 1*5 mm. 

 from the sides, so that the width of the elytra is 11 "6 mm., if 

 measured at these prominences. The backward prolongation of 

 the prosternum is 3 mm. in length, subcylindrical, a little wider, 

 and triangularly excised, at the point. The antennae are more 

 elongate than in B. calcaratuin, and are glabrous, with a setulose 

 flattened space on lower side near apex of those after the fourth- 



Note. — The description given above was founded on a single 

 specimen in the French Collection (now in the National Museum, 

 Melbourne). More recently Mr. French has received a number 

 of specimens, of both sexes, from the Pine Creek District of the 

 Northern Territory; these are smaller and present some minor 

 differences from the original specimen. I offer the following 

 note on these specimens : — 



9. Differs from ^ by prothorax shorter, wider; sides more 

 rfiunded; anterior angles more prominent. Elytra mucli wider, 



* In Pine Creek specimens this femoral tooth is a stout triangular denti- 

 form process.
