The Vitellius Skipper

Phycanassa vitellius (Phyc-a-nas'sa vi-tel'li-us) PLATE XLII, FIG. 13, 14, 15 The upper surface of the wings is largely bright tawny with the veins and outer margin brown; in the male the brown border on the outer margin is unusually narrow, covering only about one-eighth of the length of the wing; in the female it is about twice as wide; the base of the wings is more or less dusky, especially in the female, where the basal two-fifths of the wing is brownish; there is a more or less distinct brown bar at the end of cell R + M, but no trace of a brand in the male. The lower surface of the hind wings is yellow without markings.

Expanse of wings one and one-eighth to one and onefourth inches. The species vitellius was first described from the West Indies, and it may be that our form is distinct; if so, it should be known under the name logan, given to it by Mr. Edwards. It is found as far north as New England and Montana.
