New Species or Sub-species of North American 



Butterflies (Lepid.j. 



By Henry Skinner, Philadelphia, Pa. 



Eresia texana seminole n. subsp. 



Male and female. Base of the primary wing fulvous, with a black 

 ring containing a fulvous spot ; in the discal cell outward is a large 

 fulvous spot encircled with black and beyond this a black space with a 

 yellow dot in the center; further toward the apex is a lunate fulvous 

 spot. Below the cell, near the base are three fulvous dots. All the 

 other spots on both wings are yellow ; the mesial band on secondaries 

 yellow, large and more nearly quadrate than in texana. 



Described from two specimens (male and female) in the col- 

 lection of the Academy of Natural Sciences of Philadelphia 

 and a number of paratypes in the collection of the Georgia 

 State Board of Entomology at Atlanta. The specimens were 

 taken by Professor J. C. Bradley, at Bainbridge, Georgia, Sept. 

 17th. It is named from the aborigines that inhabited that dis- 

 trict as suggested by Professor Bradley. 



Pamphila sassacus dacotae n. subsp. 



The stigma of dacotae is like that of sassacus, but the markings of 

 the male in most specimens are nearly obsolete; the small black dash 

 seen in sassacus beyond the stigma is wanting in dacotae. In color the 

 new form is paler, and this in conjunction with the lack of maculation 

 gives it a peculiar appearance. The female is more differentiated from 

 sassacus than the male, being entirely fuscous ; there are three small 

 sub-apical spots, two at the end of the cell and two below these, and 

 the latter in one specimen arc translucent ; further toward the outer 

 margin are two more spots. There is a faint semi-circular band of 

 spots in the center of the secondaries. All these spots are repeated on 

 the underside. 



Described from five specimens from \'olga, South Dakota, 

 and five from Grinnell, Iowa. Type locality Volga. The in- 

 sect flies in July and August (July 16-21, Aug. 24th.) 



Pamphila mystic pallida n. subsp. 



Like the Eastern mystic but much paler in color, especially 

 the fuscous border of the wings. 



Described from a number of specimens of both sexes from 

 Volga, South Dakota. Taken in July, from the i6th to the 

 25th.
