Early Stages.—These await description.
This species, which originally was believed to be confined to Scandinavia and Lapland in Europe, and to eastern Labrador in this country, is now known to have a wide range in North America, extending from Labrador to the Carolinas on the Appalachian ranges, and occurring on the Rocky Mountains from British Columbia to southern Colorado.
(4) Hesperia cæspitalis, Boisduval, Plate XLVII, Fig. 14, ♁ (The Two-banded Skipper).
Butterfly.—On the upper side strongly resembling the preceding species, but the inner row of white spots on the hind wings is more complete. On the under side the fore wings are black, crossed by a double row of white spots, as on the upper side, these spots standing out conspicuously on the dark ground. The hind wings on the under side are more or less ferruginous, with the white spots more or less conspicuous. The fringes are checkered white and gray. Expanse, 1.00 inch.
Early Stages.—But little is known concerning these.
The species occurs in California, Oregon, and Nevada.
(5) Hesperia xanthus, Edwards, Plate XLVII, Fig. 15, ♂ (The Xanthus Skipper).
Butterfly.—Resembling the preceding species, but easily distinguished by the larger size of all the spots on the upper side of the wing and the paler under side, the secondaries being marked somewhat as in H. montivaga. Expanse, 1.00 inch.
Early Stages.—Hitherto undescribed.
