 macula quadrata, postscutello macula, sogmento dorsali primo 

 macula parva utrinque, segmeutis dorsalibus 2-7 fascia lata

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

 distinctly shorter than the third. Pronotutn strongly rounded

 Median segment broader than long, clothed with thin white

IJab. Mackay and Cairns, Q. (Turner); Brisbane, Q.

This is the Australian representative of the group of the 

 European B. quadripunctatus , Fabr., and is nearest to the 

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

 described by Bhigham under the name biocidatus. In the 

 Oriental region a dark-winged form of the female occurs, 

 named by iJingham hracatus, but I do not believe that any 

 corresponding aberration occurs in Australia. The species 

 is common in Queensland, but I never guessed the connection 

 o£ tiie sexes during my residence there. B. tricolor seems 

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

 two Australian species oi' Batozonus.
