(19) Lycæna rustica, Edwards, Plate XXXII, Fig. 17, ♂, under side (The Rustic Blue).
Butterfly.—Much like the preceding species, but a third larger, and brighter blue on the upper side of the wings of the male. On the under side the disposition of the spots and markings is precisely as in L. aquilo, but on the secondaries the dark spots and shades are all replaced by white on a pale-gray ground. Expanse, .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) Lycæna enoptes, Boisduval, Plate XXX, Fig. 30, ♁, 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 female 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 profusion 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.
