(2) =Lemonias duryi=, Edwards, Plate XXVIII, Fig. 10, ♀ (Dury's Metal-mark).
_Butterfly._--The only specimen as yet known is the type figured in our plate. I doubt whether it is entitled to specific rank, and am inclined to believe it to be a form of the succeeding species in which red has replaced the greater part of the gray on the upper side of both wings. Expanse, 1.25 inch.
(3) =Lemonias cythera=, Edwards, Plate XXVIII, Fig. 4, ♀, _under side_; Fig. 5, ♂ (Cythera).
_Butterfly._--Distinguished from _L. mormo_ by the red submarginal band on the secondaries on the upper side, the greater prevalence of red on the primaries, and by the tendency of the spots on the under side of the secondaries, just after the costa, to fuse and form an elongate pearly-white ray. The submarginal spots on the lower side of the fore wings are smaller than in _mormo_. The sexes do not differ except in size. Expanse, 1.00-1.30 inch.
_Cythera_ is found in Arizona and Mexico.
(4) =Lemonias virgulti=, Behr, Plate XXVIII, Fig. 6, ♂ (Behr's Metal-mark).
_Butterfly._--Much like the preceding species on the upper side of the wings, but darker. The hind wings on the under side are much darker than in _L. cythera_, and the pearly-white spots relatively smaller, standing out very distinctly on this darker ground. Expanse, .90-1.10 inch.
_Virgulti_ is common in southern California and Mexico.
(5) =Lemonias nais=, Edwards, Plate XXVIII, Fig. 8, ♂; Fig. 9, ♀ (Nais).
_Butterfly._--The ground-color of the upper side is bright red, clouded with fuscous on the base of the hind wings and bordered with the same color. There is a small precostal white spot on the primaries near the apex. The wings are profusely marked with small black spots arranged in transverse series and bands. The fringes are checkered with white. On the under side the wings are pale reddish, mottled with buff on the secondaries. The black spots and markings of the upper side reappear on the under side and stand out boldly on the lighter ground-color. Expanse, 1.00-1.25 inch.
_Early Stages._--These are beautifully delineated in "The Butterflies of North America," vol. ii. The egg is pale green, turban-shaped, covered with hexagonal reticulations. The caterpillar is rather stout and short, the first segment projecting over the head. The body is somewhat flattened and tapering behind, covered with tufts of hairs projecting outward and downward on all sides, only the two rows of short tufts on the back sending their hairs upward. The color is mouse-gray, striped longitudinally on the back with yellowish-white, the tufts more or less ringed about at their base with circles of the same color. The chrysalis is blackish-brown, attached at the anal end, held in place by a girdle, but not closely appressed to the surface on which pupation has taken place, and thickly studded with small projecting hairs. The larva lives on the wild plum.
