Part 36

Larva feeds on columbine (Aquilegia). Ranges from New England to Georgia, and westward through the valley of the Mississippi.

(4) Thanaos juvenalis (Fabricius), Plate CXXXVI, Fig. 1, ♀ (Juvenal’s Dusky-wing).

A large species with translucent spots arranged as an interrupted band beyond middle of wing. Expanse 1.35-1.60 inch.

Ranges from Quebec to Florida and westward to Arizona.

(5) Thanaos petronius Lintner, Plate CXXXVI, Fig. 2, ♂ (Petronius’ Dusky-wing).

Somewhat resembling the preceding, but translucent spots much fewer in number and upper side much darker. Under side uniformly dusky with few light spots. Expanse 1.50-1.75 inch.

Confined to Florida so far as known.

(6) Thanaos martialis Scudder, Plate CXXXVII, Fig. 1, ♂ (Martial’s Dusky-wing).

Upper side paler than in most species, with a purplish gray cast, all light spots of upper side repeated more distinctly on under side. Expanse 1.25-1.40 inch.

Ranges from Massachusetts to Georgia, westward to Missouri and New Mexico.

(7) Thanaos horatius Scudder, Plate CXXXVII, Fig. 2, ♂ (Horace’s Dusky-wing).

Smaller than T. juvenalis, which it resembles; paler above on both wings, below more profusely mottled on hind wings. Expanse 1.65 inch.

Ranges from Massachusetts to Texas.

(8) Thanaos funeralis Lintner, Plate CXXXVII, Fig. 3, ♂ (The Funereal Dusky-wing).

Hind wings very dark, partly fringed with pure white. Expanse 1.35 inch.

Found from western Texas to Mexico.

SUBFAMILY PAMPHILINÆ (THE PAMPHILIDS).

The male never has a costal fold on the fore wing, but in most of the genera has a discal stigma on the fore wing, the only exceptions to this in our fauna being in the case of the three genera Amblyscirtes, Pamphila, and Oarisma. The antennæ are short, in some genera very short, clubbed at the end and provided in many genera with a little finely pointed tip at the end of the club, which sometimes is bent backward. The third joint of the palpi is generally small, inconspicuous, and often pointing forward. The lower radial in the fore wing always is nearer to the median than to the upper radial; the lower radial in the hind wing is generally lacking. When at rest they raise the fore wings, folding them together, while the hind wings are held horizontally. This attitude is characteristic of this subfamily.

GENUS AMBLYSCIRTES SCUDDER

(1) Amblyscirtes vialis (Edwards), Plate CXXXVIII, Fig. 1, ♂ (The Roadside Skipper).

Wings below much as on upper side, except that outwardly they are lightly laved with gray. Expanse 1.00 inch.

Ranges from Canada to Florida, and from the Atlantic to the Pacific.

(2) Amblyscirtes samoset (Scudder), Plate CXXXVIII, Fig. 2, ♂ (The Pepper-and-Salt Skipper). (See Plate on p. 208.)

Below wings pale gray, the light spots of upper side reappearing. Hind wing marked by semicircular median band of white spots, a small spot at end of cell, and conspicuous white spot about middle of costa. Expanse 1.00-1.10 inch.

Ranges from Maine to Michigan and south on the Allegheny Mountains to West Virginia.

(3) Amblyscirtes textor (Hübner), Plate CXXXVIII, Fig. 3, ♂, under side (The Woven-winged Skipper). (See Plate on p. 208.)

Easily recognized by means of our figure. Expanse 1.25-1.45 inch.

Ranges from North Carolina to Florida and westward to Texas.
