Genus Lycaena 



the under side the disposition of the spots and markings is pre- 

 cisely as in L. aquilo, but on the secondaries the dark spots and 

 shades are all replaced by white on a pale-gray ground. Ex- 

 panse, .90-1.00 inch. 



Early Stages.— We are in complete ignorance as to these. 



The butterfly is found in British America and on the Western 

 Cordilleras. 



(20) Lycaena enoptes, Boisduval, Plate XXX, Fig. 30, 9 , 

 under side; Fig. 51, $ (The Dotted Blue). 



Butterfly.— The wings on the upper side are purplish-blue,— 

 pale in the male, darker in the female, — bordered with dusky, 

 more heavily in the female than in the male. The fringes are 

 white, checkered with dusky at the ends of the veins. The fe- 

 male sometimes has the hind wings marked on the upper side 

 with red marginal spots on the inner half of the border. On the 

 under side the wings are pale bluish-gray, marked with a profu- 

 sion of small black spots, those on the outer margin arranged in 

 two parallel lines, between which, on the hind wings, are red 

 spots. Expanse, 1.00 inch. 



Early Stages. — Awaiting description. 



Enoptes ranges from Washington to Arizona. 



(21) Lycaena glaucon, Edwards, Plate XXX, Fig. 31, 9, 

 under side; Fig. 39, $ (The Colorado Blue). 



Butterfly. — Purplish-blue, closely resembling the preceding 

 species, but having the black margin of the wings broader than 

 in L. enoptes, with the dark crescents of the marginal series on 

 the under side showing through as darker spots in the margins 

 of the hind wings. The female has a band of orange spots on 

 the margins of the secondaries. The two marginal rows of 

 spots on the lower side of the wings are arranged and colored as 

 in the preceding species. Expanse, 1.00 inch. 



Early Stages.— Of these we must again confess ignorance. 



Glaucon ranges from Washington into California, and east- 

 ward to Colorado, where it is quite common in the mountain 

 valleys. 



(22) Lycaena battoides, Behr, Plate XXXII, Fig. 11, $ 

 (Behr's Blue). 



Butterfly.— On the upper side paler blue than the preceding 

 species, with the hind margin tinged with reddish, shining through 

 from below, and small crescentic dark spots. On the under side
