Adelpha (Heterochroa) bredowi and californica 

 (Lepidoptera). 



By Henry Skinner, Philadelphia, Pa. 



These two species have been considerably confused in the 

 literature of the subject. Some authors have placed califor- 

 nica as a synonym and others have confused the two. I had 

 never carefully studied them and had supposed that californica 

 was only a slight race of bredowi without any constant charac- 

 ter or characters to separate it. We lately received some speci- 

 mens from Texas, collected by Mr. H. A. Wenzel, and in de- 

 ciding which name to place them under, I was led to examine 

 the material at my comand, which consists of twenty-nine speci- 

 mens from a number of localities. 



Bredowi was described by Hubner, Zutr. Exot. Schmett. f. 

 825, 826. The Biologia Centrali-Americana gives the follow- 

 ing distribution for it : Arizona ; Chihuahua, Oaxaca, Mexico ; 

 San Geronimo, Polochic Valley, Santa Rosa in Vera Paz, 

 Guatemala. Limenitis eulalia Doubl. Hew., Gen. Diurn. Lep. 

 t. 36, f. I is placed as a synonym. 



Heterochroa californica was described by Butler. Proc. Zool. 

 Soc. Lond., 1865, p. 485, with the habit given as California. It 

 is figured by Edwards in his Butt. Xth. Amer. i. pi. 44, 1870, 

 under the name bredowi. Mr. Edwards corrected this refer- 

 ence in his Catl. of 1884, and gives the habitat as Cala. ; Ariz. ; 

 Nev. It is also figured in Holland's Butterfly Book and in 

 Wright's Butterflies of the West Coast. 



Godman and Salvin mention the californica of Butler in the 

 Biologia and say several small differences serve to distinguish 

 it from bredowi, the latter being recorded from Arizona, frott. 

 specimens collected by Morrison. At the end of his description 

 of californica ]\Ir. Butler says it is closely allied to bredowi 

 and then points out a number of differences between the two. 

 Of these I have found but one that is constant in the speci- 

 mens examined — "the basal upper half of the hind wing is 

 crossed by an additional short orange band." 



On the under side of the secondary wing there is a broad
