Among the scanty literature on this insect is the following on 

 its capture in Mexico, which may interest some readers of this 

 journal who have not access to a copy of the Biologia Centrali 

 Americana^ 



A. nokomis W. H. Edw. 



Pro. Acad. N. S. Phila., 1862, p. 220 $ .^ 

 But. N. A. I Arg. IV tabl ($9).^ 

 Snyder, Occ. Mems., Chicago Ent. Soc. I. 33, 1900.^ 

 North America, Rocky Mts.,i Bitter Root Mts.,- Southern Utah,^ 

 Arizona.^ 



Mexico, near Durango City (Becker). 



"Mr. Becker has sent us a single female specimen of this species 

 from Durango. It differs from Edwards' figures of that sex of A. 

 nokomis and from Arizonan females in our collection, having rather 

 more than the basal half of each wing almost uniformly fuscous be- 

 tween the black spots, and on the secondaries beneath the silvery 

 spots from the base to the middle obscure greenish ochreous coloring. 

 The Mexican insect in this respect being almost intermediate betweeen 

 the female of nokomis Edw. and A. leto Behr." 



Note by Henry Skinner. 

 There is not much that I can say about the question raised 

 by Mr. Winn as to the withdrawal and replacement of plates 

 issued in Volume I of Edwards' Butterflies of North America. 

 Mr. E. T. Cresson is the only person alive who had to do with 

 the publication and he does not remember anything about it. 

 It is likely that the figure of nokomis by Wiest was intended 

 by Mr. Edwards to be replaced by what he subsequently called 

 nokomis, drawn by Miss Mary Peart, as in the preface to the 

 Third Series of the Butterflies of North America he says : 

 "At first there was difficulty in finding an artist who could 

 faithfully portray the butterfly on stone, and two were tried 

 who were far from satisfactory. With Part Two (Argynnis 

 VI) came in Miss Mary Peart, who has supported the work to 

 this day." An examination of a number of copies of the work 

 would probably answer the question raised by Mr. Winn. 

 The female specimen mentioned in the Biologia Centrali- 

 Americana I take to be what Dr. W. J. Holland described as 

 Argynnis caeridescens.
