BUTTERFLIES OF MONTANA. 155 



THE PAWNEE SKIPPER, Erynnis pawnee, Dodge. 



Male expanse, 1.45 inches, 36 mm. Primaries above fulvous. Sub- 

 costal, submedian and subdorsal veins black at the base. Stigma black 

 and conspicuous, followed by a dusky shade. A small black line at the 

 extremity of the disk is preceded by a yellowish white or semi-transparent 

 spot in the disk; a similar spot, triangular in shape, appears between 

 the first and second median veinTets at their divarcation, and two others 

 between the sixth and seventh subcostal veinlets. The outer margin is 

 broadly bordered with brown, which is finely powdered with fulvous scales 

 toward the apex. 



Two nearly square fulvous spots between the last subcostal and first 

 median veinlets, separate an oval brown patch that lies at the extrem- 

 ity of the disk, from the border. Costal edge blackish. Fringe white, 

 dusky toward the apex. 



Secondaries fulvous, bordered with brown; broadly and darkest along 

 the anterior edge, narrowly on the outer edge, where it appears as cunei- 

 form spots between the veinlets, and broadly along the innner edge, where 

 it is sprinkled with fulvous. Most of the veins on both wings are black. 

 Underside of both wings yellow. Primaries black at base, having a black 

 line corresponding to the stigma. 



Inner margin brown, preceded by a large whitish patch. Five pale 

 whitish spots near the apex, another in the disk, and one between the 

 first and second median veinlets. Fringe white at the anal angle, brown 

 tipped with white at the apex. Secondaries have a whitish spot in the 

 disk, and are crossed by a nearly straight row of small whitish spots. 

 Head and thorax greenish yellow. Body black. Abdomen, breast and 

 palpi yellowish white. Antennae black and yellow above, white tipped 

 with chestnut below. The spots on the under side of secondaries some- 

 times obsolete. 



Female, light brown above, with a slight purplish reflection. Pri- 

 maries sprinkled with fulvous scales near the base and inner edge. 

 There is a large, square, wKite spot in the disk, and an unequal, curved 

 row of nine white spots extend from the costa beginning about two-tenths 

 of an inch from the apex to the submedian vein. The first three spots 

 are narrow and equal, the fourth and fifth are small and square and lie 

 nearest the outer edge of the wing, the sixth is large and triangular, the 

 seventh largest and square, the eighth and ninth are irregular in shape 

 and partly fulvous. 



Secondaries darkest along the anterior margin. A curved row of 

 five whitish yellow spots, of which the second and third are longest, 

 crosses the wing beyond the disk, and in the disk is a small yellow spot. 

 A yellow streak precedes the last median veinlet, run to the outer margin. 

 Fringe of all the kings white. Below, on the primaries, the same white 

 spots appear as above, except that th eeighth and ninth are merged in a 

 large whitish patch situated as in the male. A brown patch covers part 

 of the base and inner margin, and extends to the center of the wing. On 

 the secondaries three small white spots appear near the apex. The 

 ground color of both wings is yellowish white, most deeply tinged with 

 fulvous near the costal border of the primaries. Fringes white. Head,
