160 NOTES ON AUSTRALIAN COLEOPTERA, 



sinuate, vermiculate form; breast coarsely, episterna finely punc- 

 fcatt : epipleupse coarsely wrinkled, abdomen thickly striolate, the 

 apical segment finely punctate. Dimensions: 9 - 5 x G mm. 



Hah. — Brisbane (Mr. H. Hacker). 



A single specimen, sent by its captor, shows a species clearly 

 differentiated from its allies, by its greater convexity and thick 

 lateral margins of prothorax inter multa alia. Theelytral sculp- 

 ture is somewhat similar to that of B. rugatus Cart., but it is 

 less nitid, with the transverse wrinkling more pronounced, while 

 its pronotum is sculptured more like that of 11. varicolor Cart. 

 The sutural region is depressed. 



Type in the Queensland Museum.

 rounded, sides widely rounded with greatest width behind middle, 

 then sinuately and strongly constricted to the widely dentate

 wards; a large basal fovea within these angles, base (between 

 foveas) truncate; foliate margins wide and horizontal, with dis- 

 tinct separating sulcus, and (in general) three setiferous punc-
