1-4 11 que rufo-testaceis ; capite elongate, inter antennas 

 inipresso, postice utrinque fovea magna instructo ; pro- 

 thorace brevi vix subcordato, basi utrinque foveolato, foveis 

 linea transversa conjunctis ; elytris prothorace dimidio 

 longioribus, stria suturali profunda altera discoidali (hac

The antennae are stout and ratlier short (scarcely longer than 

 the head and prothorax together); joint 1 is scarcely so long as 

 2 and 3 together, 3 is much more slender than the rest, 5 and 6 

 are stouter (5 scarcely larger than 6), 5-10 all transverse and not 

 much different inter se, l^ut all a little triangularly dilated on the 

 inner side (so that the antennae seem subserrate), 1 1 subconic and 

 nearly as long as the preceding two together, l)ut not stouter. 



I am doubtful of the sex of the example before me, as I find 

 no noticeable character in the ventral segments, while the an- 

 tennal structure seems rather of the male type. 



I do not think any previously described Australian Bryaxis of 

 large size is of a nearly uniform black colour.

The central basal fovea of the prothorax (as in B. Ovensensis) 

 is scarcely more than a slight dilatation of the transverse furrow. 

 The antennae are as long as the head and prothorax together ; 

 joints 1 and 2 are stouter than the following joints ; 1 a good 

 deal longer than 2, 3 a little longer than 2 ; 1-7 scarcely so long 

 as 3, and differing little inter se except in 5 being a little the
