description must not be taken to imply that these markings are of a constant and invariable 

 character, as in the small series now before me there is slight but unmistakable divergence 

 in that respect* 



Group ATHNABIA.

I propose under the above name to group together a very large number of genera, 

 comprising some of the largest species in the family. It is in this group also that the posterior 

 wings attain the greatest amount of caudate elongation, I have used the number of these 

 tail-like appendages as an assistant factor in the artificial key to the genera which here follows, 

 but in so doing have only recognised them when they :tre distinctly developed.
