Pamphila myus, n. sp.

Male.—Expanse .95 of an inch. Upper surface dark olivaceous brown, with a slight vinous reflection, about the same shade as cernes, which it much resembles. The primaries have the discal cell and the area in front of the cell like cernes, heavily washed with yellow of a little darker shade than that species, the same color ectending beyond the cell along the costal area three fourths the distance from the base to the outer margin (as the wings are spread); below the cell the same shade of yellow extends along the median vein the same distance, the area below this to the margin rather heavily sprinkled with yellow scales, except the space beyond the lower half of the stigma. This varies but little from the yellow of cernes. In cernes there is a quadrate sinus of the terminal dark brown of the wing dipping into the yellow beyond the cell, coming up to the cross vein. In this species the sinus is of the same width, but extends inward above the median vein, ending in a point half way to the base of the wing. The stigma is black, narrow, oblique, entire, though constricted below the middle, shorter than in cernes, does not reach the submedian below, and the upper end only reaches the second branch of the median, while in cernes it passes beyond this veinule, the lower third bent a little towards the base, in width not more than half as wide as in cernes; below the stigma an oblong patch of blackish scales that are bronzy in certain lights. Secondaries sprinkled with yellow scales, the inner half with yellowish hairs that are less olivaceous than in cernes.
