Synonymy.— A. ducens, Walker, and N. grandis, Schiner, 

 evidently belong to the same species, which varies remark- 

 ably in size. It differs from C. albofasciata, Thomson, and 

 C. lateralis, Newman, by the absence of the white fascia on 

 the wings. 



Comptosia aurifrons, Macquart.

 represented in most collections. 



Hab. — New South Wales and Victoria.

 ney, which were identified by White as Walker's species. In 

 general appearance they resemble C. ducens. Walker, but 

 differ structurally by having an appendix in the form of a
