Common in Central America and Mexico, ranging north through the hotter parts of the Gulf States, and has been recorded from southern Illinois. Occurs in southern California and Arizona. The larva feeds on mistletoe.

(2) Thecla m-album Boisduval & Leconte, Plate LXXX, Fig. 1, ♂ (The White-M Hair-streak).

Smaller than the preceding species, bluer, and not inclined to greenish at base of wings on upper side; on under side fore wing crossed by a submarginal and a median line of white, continued on the hind wings, zigzagged at anal angle so as to look like an inverted M; near this is a rounded crimson patch; anal angle black glossed with blue. Expanse 1.35-1.45 inch.

Ranges from New Jersey and Wisconsin to Venezuela.

(3) Thecla crysalus Edwards, Plate LXXX, Fig. 2, ♂ (The Colorado Hair-streak).

Upper side as in our figure, under side marked with white lines edged with brown. Orange spots of upper side reappear below, but at anal angle are transformed into red eye-spots pupilled with black and margined with metallic green. Expanse 1.50 inch.

Ranges from Colorado to eastern Arizona.

(4) Thecla favonius Smith & Abbot, Plate LXXXI, Fig. 1, ♂ (The Southern Hair-streak).

On the under side the wings are marked much as in T. m-album, but in the region of the median nervules is a rather broad transverse carmine streak inwardly edged with dark lines. Expanse 1.00-1.15 inch.

Found in the Gulf States and as far north as South Carolina.

(5) Thecla wittfeldi Edwards, Plate LXXXI, Fig. 2, ♀, Type (Wittfeld’s Hair-streak).

On the lower side both wings are crossed beyond the middle by two parallel pale lines bordered with darker tints, and at the end of the cells have each a short whitish bar. The anal angle is adorned with blue scales, before which is a red eye-spot of large size, externally marked with black. Expanse 1.25-1.35 inch.

Found in the region of Indian River, Florida.

(6) Thecla autolycus Edwards, Plate LXXXII, Fig. 1, ♂ (The Texas Hair-streak).

The carmine spots on the under side of the wings are not arranged across the median nervules as in T. favonius, but are located in the vicinity of the anal angle crowning the black crescents near the inner end of the outer margin. Expanse 1.15-1.30 inch.

Ranges from Missouri and Kansas to Texas.

(7) Thecla melinus Hübner, Plate LXXXII, Fig. 2, ♀ (The Common Hair-streak).

This common little butterfly may easily be recognized by its plain slaty upper surface, marked by a large black spot crowned with crimson between the origin of the two tails on the hind wings. Expanse 1.10-1.20 inch.

The caterpillar feeds on hop vines. The insect is found throughout temperate North America, thence southward into Mexico and Central America on the highlands.

(8) Thecla grunus Boisduval, Plate LXXXIII, Fig. 1, ♂ (Boisduval’s Hair-streak).

Wings on the upper side are as shown in our figure, but tawnier. On the under side the wings are pale tawny with transverse marginal and submarginal rows of small dark spots on both wings. Two or three of the marginal spots near the anal angle are conspicuously black crowned with a metallic green crescent. Expanse 1.10-1.20 inch.

The larva feeds upon the leaves of the live-oak (Quercus chrysolepis). Found in California and Nevada.

(9) Thecla edwardsi Saunders, Plate LXXXIII, Fig. 2, ♂ under side (Edwards’ Hair-streak).

Our figure shows the under side; on the upper side the wings are dark brown glossed with plumbeous, with a pale sex-mark on the fore wing of the male near the costa. Expanse 1.15 inch.

The caterpillar feeds upon the young leaves of various kinds of oak. The species ranges from Quebec westward to Colorado and is not uncommon in New England, New York, and western Pennsylvania.

(10) Thecla acadica Edwards, Plate LXXXIII, Fig. 3, ♂ (The Acadian Hair-streak).

The wings on the under side are pale wood-brown, with a black bar at the end of the cells, and submarginal and median bands of small black spots surrounded with white; on the hind wings there is a submarginal row of red crescents, growing smaller from the anal angle toward the outer angle. Near the anal angle are two conspicuous black spots separated by a broad patch of bluish green scales. Expanse 1.15-1.25 inch.

The caterpillar feeds upon willows. The insect ranges from Quebec to Vancouver Island.
