Note. — I have carefully compared all the figures of insects hitherto 

 placed as synonyma of this species with the specimens in the National 

 Collection, and I find that D. egialea and D. damocles are quite di- 

 stinct. D. niavius (Gen. Diurn. Lep. pi. 11. f. 3) is also a separate 

 species, only resembling Cramer's insect in coloration.
