_Butterfly_, ♂.--Ground-color brownish-black, fulvous on the costa, with submarginal, median, and basal rows of yellow spots. Both the primaries and secondaries have a marginal row of red spots, and the former have in addition a submarginal row of such spots. The under side of the primaries is reddish-fulvous, with the markings of the upper side reproduced. The secondaries have a marginal row of yellow crescents, then a black band inclosing yellow spots, then a median band of long yellow crescents. The remainder of the wing to its insertion is black, spotted with yellow. ♀.--Much like the male. Expanse, ♂, 1.50 inch; ♀, 1.75 inch. _Early Stages._--Unknown. This pretty insect ranges from southern California and Arizona to Nevada, Montana, and British America. (23) =Melitæa wrighti=, Edwards, Plate XVII, Fig. 9, ♂; Fig. 10, ♀, _under side,_ (Wright's Checker-spot). _Butterfly._--Much like _M. leanira_, but with more fulvous upon the upper side of the wings, and the under side yellow. The black bands on the secondaries are reduced, and the dividing-lines between the spots are confined to the nervules, which are narrowly black. This is probably only a varietal form of the preceding species. I figure the types. Expanse, ♂, 1.30 inch; ♀, 1.80 inch. _Early Stages._--Unknown. Habitat, southern California. (24) =Melitæa alma=, Strecker, Plate XVII, Fig. 1, ♂ (Strecker's Checker-spot). _Butterfly_, ♂.--The upper side of the wings is bright fulvous, with the margins and veins black. There are three rows of transverse spots paler than the ground-color. The fore wings on the under side are pale fulvous, with pale-yellow spots and a submarginal and marginal row of yellow spots separated by a narrow black line. The hind wings on this side are yellow, with the veins and margins black, and a transverse double band of black on the outer margin of the median area. ♀.--Much like the male, but larger, and redder on the upper side. Expanse, ♂, 1.25 inch; ♀, 1.50 inch. _Early Stages._--Unknown. The specimens I have came from the Death Valley. The species occurs in southern Utah and Arizona.
