 p. 356). 



"Fore wings with the costa regularly arched; tip 

 obtuse and rounded ; hind margin rounded, very slightly 

 oblique, disc with secondary cell. Hind wings rather 

 broader than the fore wings, obtusely angulated on the 

 hind margin opposite the median nervules ; inner margin 

 deeply and sharply excised, with a cylindrical appendage 

 along the inner margin from the base, the lower portion 

 of which is free." 



The close resemblance of the specimen now before me 

 to the North American species of Exartema, both in form 

 and in ornamentation, is remarkable, and it would be 

 interesting to ascertain for certain if the hind wings of 

 the male exhibit any resemblance to the pecular structure 

 which distinguishes that genus; in which case only 

 could Herr Lederer be held to be justified in interpreting 

 the original description of Eccopsis as applicable to 

 venustana, Hub., which would probably justify also the 

 substitution by priority of that genus for Exartema, 

 Clemens.*

* Since writing the above I hare received, through the kind 

 assistance of Mr. W. F. Kirby, a slight sketch of the hind wing of 

 the original male specimen of Eccopsis wcihl- 

 bergiana, described by Zeller, for which I arn 

 indebted to Mr. C. Aurivillius, Assistant in 

 the Entomological Department of the State 

 Museum at Stockholm. Although the wing 

 is somewhat narrower and more tapering towards the apex than 

 those of the American species of Exartema, this sketch tends 

 strongly to confirm the view that the genera Eccopsis, Zeller, 

 and Exartema, Clemens, are identical.
