A. nigricornis, Blackb., has been omitted as undetermined. It 

 seems possible that it is one of the many varieties of lateralis, 

 Boh. 



As Blackburn pointed out, the most striking character of this 

 genus lies in the antennae of the male. For this reason a close 

 examination is necessary. With a Zeiss binocular the species can 

 be thus readily differentiated. The following notes have been made 

 -on the species. 



Synonymy. — A. lateralis, Boh. =-4. palpalis, Macl. =A. Mastersi 

 Macl. 



The synonymy of the last two was noted by Blackburn. The 

 Queensland specimens of the $ (Mastersi) are often nearly black. 



A. lateralis, Boh., was described as from Sydney, and the de- 

 scription answers to the commonest Sydney species, which I find 

 identical with the type of palpalis, Macl. The wide distribution of 

 this from Queensland to South Australia is noteworthy. 



The $ has short antennal joints of nearly equal length, joints 

 8-10 strongly hollowed beneath, with one angle a little produced.
