(17) =Melitæa harrisi=, Scudder, Plate XVII, Fig. 5, ♂; Fig. 6, ♀, _under side_; Plate V, Figs. 17-18, _chrysalis_ (Harris' Checker-spot).
_Butterfly_, ♂.--Wings fulvous, black at the base and on the outer margin, with five fulvous spots in the cell of the fore wing, two below the cell; and three in the cell of the hind wing. The black border is widest at the apex of the fore wing, and below this runs inwardly on the veins. There are two white spots near the apex. At the anal angle on the hind wing the border is somewhat divided so as to present the appearance of two indistinct lines. On the under side the wings are fulvous, marked with black bands and spots, and crossed by bands and crescents of pale yellow, as is shown in the figure on the plate.
♀.--The female is much like the male. Expanse, ♂, 1.50 inch; ♀, 1.75 inch.
_Egg._--The eggs are lemon-yellow, in the form of a truncated cone, with fifteen or sixteen vertical ribs, which are highest about the middle.
_Caterpillar._--The matured caterpillar is reddish-fulvous, with a black stripe on the back. Each segment is marked with one black ring before and two black rings behind the sets of spiny tubercles with which the segments are adorned. There are nine rows of spines, those above the feet being quite small. The spines are black, tapering, and set with diverging black hairs. The food-plants are aster and _Diplopappus umbellatus_.
_Chrysalis._--The chrysalis is pearly-gray or white, blotched with dark brown or black.
This choice little butterfly ranges from Nova Scotia to Wisconsin, extending as far south as northern Illinois, and northward to Ottawa.
(18) =Melitæa elada=, Hewitson, Plate XVII, Fig. 2, ♂ (Hewitson's Checker-spot).
_Butterfly_, ♂.--The wings on the upper side are black, crossed by numerous bands of small fulvous spots, the one crossing the middle of the median area being composed of the largest spots. The fore wings on the under side are fulvous, shading outwardly into ferruginous. The spots and bands of the upper side reappear upon the under side, but are lighter, and the submarginal row of crescents is pale yellow and very distinct, the spot between the second and third median nervules being the largest, and the spot between the fourth and fifth subcostals being only a little smaller. The under side of the hind wings is deep ferruginous, crossed by bands of pearly pale-yellow spots, those of the outer margin being the largest.
