E. cooperi Behr. 



This species has never been satisfactorily identified ; it was de- 

 scribed from Clear Lake, Lake Co., Calif, and separated from chal- 

 cedona largely on the strength of the very different larva which ac- 

 cording to Behr is 'brimstone yellow with a dorsal and lateral black 

 stripe' and feeds on Scrophidaria; the imago is said to be similar to 

 chalcedona but lacking 'the yellowish halo around the lunules of the 

 brown band on the underside' of secondaries, the red portions of both 

 being more somber and less of a fiery red than in chalcedona. Our 

 Calif ornian entomologists should be able to solve the puzzle by search- 

 ing in the type locality for the larva which seems readily recognizable. 

 In the Edwards' Collection are two specimens labelled cooperi and 

 purporting to have been bred by Dr. Behr and sent to Edwards in 

 1863 as types; we were utterly unable to separate these from chal- 

 cedona, the wing shape and type of maculation being the same in both 

 species. 



Perdiceas Edw., described from Tenino, Wash., has been placed 

 as a synonym of cooperi; in the Edwards' Collection are 2 $ 1 2 

 labelled 'Puget Sound, Wash.' 'cooperi=perdiceas' and several other 

 specimens from the same region simply labelled cooperi; these seemed 

 to us distinct from Behr's two specimens but we had no material that 

 would exactly match the perdiceas types and do not therefore feel com- 

 petent to decide the point. 



E. baron i Edw. 



This species is usually credited to Hy. Edwards with the descrip- 

 tion published in Papilio, Vol. I, 52, 1881, but the name baroni was 

 first used by W. H. Edwards in 1879 (C. Ent. XI, 129) the larva being 

 described and a very short diagnosis of the imago being given at the 

 close of the article; the species was figured in Butt. N. Am. Ill, Mel. 

 PI. I. We recently discovered two of the presumable types which 

 served for Hy. Edwards' description mixed up with the types of E. 

 rubicunda in the Hy. Edwards' Collection; they are from Mendocino 

 Co., Calif., the type locality, and agree with W. H. Edwards' figures so 

 that it is evident that whichever author receives the credit for the 

 specific name there will be no mix-up regarding the species itself.
