At the time of writing my article on the “Red Wing” species of Catocalæ I was in doubt about a few forms, as there were some I had not seen. Since writing that, Mr. O. C. Poling, of Quincy, Ill., kindly sent me for examination some of these, and many others from his large collection; besides enriching my cabinet with several species it did not before contain. To bring the “Red wings” into what seems to be their proper relationship my last article needs a revision, which I will here make before taking up the “Yellow Wing” forms.

Marmorata should probably precede Concumbeus, where it may be found in this series. Mr. poling's new species, Frenchii, should follow Californica and its varieties. Mr. Heury Edwards described both Jessica and Portia as related to Californica. These, with Mr. Poling's species, Hippolyta and Luciana, it seems ro me should constitute what might be called the Californica group.
