Upper side pale black, along inner margin of primaries and 

 base, and inner half of secondaries, violet-blue ; on primaries a 

 dark, rough stigma ; secondaries have two tails, the anterior one 

 short, the other long, both black with white tips; a dark patch at 

 anal angle, and two in the next adjoining interspaces on the 

 margin. 



Under side gray-brown ; both wings edged by a brown line^ 

 next which the scales are whiter than elsewhere, giving the ap- 

 pearance of a second line, white; primaries have an obscure sub- 

 marginal series of brown lunules, an extra-discal, somewhat macu- 

 lar, band covering whole wing, brown, with no scales, and edged 

 without by white, at the end of cell a brown bar, with red scales 

 and white on either side. Secondaries have a clouded marginal 

 border, indistinct brown lunules running through a whitish ground; 

 a black anal patch, over which is a red edging, red also on the 

 inner margin, just above ; a rounded red spot, with black at 

 the margin, between the two lower branches of median ; across 

 the disk a macular band from margin to margin, bent at a double 

 angle, or W, below median, brown, much covered with red, and 

 edged outside by white ; an obscure streak at end of cell, and a 

 brown and red bar above cell half way between the band and 

 base. 



Body above fuscous, the abdomen whitish, with orange scales; 

 under side of thorax and abdomen white ; legs biown and white ; 

 palpi white, brown above and at tip ; antennae fuscous, narrowly 

 ringed with white; club black, fulvous at tip. 



From 2 3 taken near Prescott. 



This pretty species is allied to Clytie, Eciw., described from a 

 single female, in Field and Forest, Vol 3, page 232, 1877, ^"<^ ^t 

 first view I thought these Arizona examples were the males of 

 that species. Clytie was taken by Mr. Boll at San Antonio. Sec- 

 ondaries are wholly light blue, color of Lycaena PsetidargiohiSy. 

 and so are the inner margins of primaries, whereas Leda is violet- 

 blue ; the under side is marked with red as in Leda^ but more 

 heavily. Both wings are edged by a red line, and hence it differs 

 from Leda. So the outer tail is white, and theother black, partly 

 fringed on one side by white, whereas in Leda both are blacky 

 with only the extreme tip white. The abdomen of each is white^ 

 but Leda has much orange on upper side. So that the two forms 

 are distinct, though of same sub-group. 



1 take the opportunity to reprint the description of Thecla 

 Clytie, as Field and Forest is no longer published, and the vol- 

 umes are not readily accessible.

Female, — Expands .8 inch. 



Upper side of primaries blackish, except on the inner margin 

 up to cell, where the color is light blue, forming a pretty reg- 

 ular arc of a circle, terminating at three-fourths the distance from
