the wing quite agree, as will be seen by comparing the wing of A. 

 erythrochlamys with that of that species. 



The first primary in A. ferruginea is much bigger, and the dis- 

 tance between its tips and the tip of the second primary is 1*5 inch,

 this varies a good deal, and the best difference between the two species 

 lies in the larger size and greyish flanks of A. ferruginea.
