 Antennse stout, the joints moderately arcuate beneath, but 

 less strongly so than in tricolor, second joint of the fiagellum 

 distinctly shorter than the third. Pronotuni strongly rounded 

 at the anterior angles, the posterior margin widely arched. 

 Median segment broader than long, clothed with thin white

This is the Australian representative of the group of the 

 European B. quadrt'jyuiictatus, Fabr., and is nearest to the 

 Asiatic B. orientalis, Cam., the female of which has been 

 described by Bingham under the name hiocidatus. In the 

 Oriental region a dark-winged form o£ the female occurs, 

 named by 13ingham hracatus, but I do not believe that any 

 corresponding aberration occurs in Aurftralia. The species 

 is common in Queensland, but I never guessed the connection 

 of the sexes during my residence there. B. tricolor seems 

 to be a rare species. As far as I know these are the onlj 

 two Australian species of Batozonus.
