Hah. -(/ooktown, North Queensland. Taken by myself, Jan- 

 uary, 1908. 



Type in Coll. Tillyard. Unique. 



This ma<j;nificent insect is clearly very closely allied to A. 

 fidva Esb.-Pet., from which it differs by its smaller size iA.fidva, 

 forewing 72 mm., total length oa mm.) and darker colouration, 

 as well as by having four cross-veins in the radial space. Tn 

 A. /idva, the antennte are pale yellowish-brown, the head, pro- 

 thorax, and mesothorax yellowish-red. The legs in A. J'ulva 

 have the tibiae differently marked; the abdomen is brown, with 

 paler apex; the apices of the segments darkened. 



The differences separating A. peferseni from A. fulva appear 

 to be of the same order as those separating A fundafus from 

 A. sublet idens. In both cases, we appear to be dealing with a 

 pair of geminate species, but, in the case of A. peterseni and 

 fidva, as the type of each is a unique specimen, we cannot yet 

 say what the cunstanf differences between them ma}? be.
