(16) Thecla niphon (Hübner), [Plate LXXXVI], Fig. 1, ♀, under side (The Banded Elfin).

Our cut gives an excellent idea of the markings of the under side. On the upper side the insect is plain reddish brown. Expanse 1.10 inch.

The caterpillars feed upon pines. The insect ranges from Nova Scotia to Colorado in the Northern States, and is only found in pine woods, but is never very abundant.

(17) Thecla irus (Godart), [Plate LXXXVI], Fig. 2, ♂ (The Hoary Elfin).

Grayish brown on the upper side, on the under side of the same color, but paler on the outer margins and darker toward the base; small crescents appear on the outer margins of the hind wings below, or they may be absent. Expanse 1.10 inch.

The larva feeds on young wild plums just after the petals of the flower have dropped away. The species ranges from the Atlantic to the Pacific in the latitude of New England.

(18) Thecla henrici Grote & Robinson, [Plate LXXXVI], Fig. 3, ♀ (Henry’s Hair-streak).

Very much like the preceding species, but with the outer half of the wings laved with reddish brown. The hind wings on the under side are blackish brown; on the basal half of the outer margin paler, the division between the dark and light shades being irregular and sharply defined. Expanse 1.00-1.10 inch.

This species, like the preceding, feeds on young plums. It ranges from Maine to West Virginia, and is not very common.
