_Butterfly._--Brown on the upper side, in some specimens bright fulvous bordered with brown. On the under side the wings are pale red, shot with pea-green on the secondaries and at the base of the primaries. The markings of the under side are much as in the preceding species, but the line on the hind wing dividing the discal from the limbal area is broader and very white, and the spots between it and the margin more conspicuous. Expanse, 1.12 inch. _Early Stages._--Unknown. It is reported from Arizona and southern California. It has been named siva by Edwards, and the figure is from his type so labeled. (22) =Thecla damon=, Cramer, Plate XXIX, Fig. 32, ♂, _under side_; var. =discoidalis=, Skinner, Plate XXIX, Fig. 29, ♂; Plate V, Figs. 30, 31, _chrysalis_ (The Olive Hair-streak). _Butterfly._--On the upper side bright fulvous, with the costa, the outer margins, and the veins of both wings blackish, darkest at the apex. On the under side the wings are greenish, crossed on the fore wing by a straight, incomplete white line, and on the hind wing by a similar irregular line. Both of these lines are margined internally by brown. There are a couple of short white lines on the hind wing near the base, and the usual crescentic spots and markings on the outer border and at the anal angle. Expanse, .90-1.00 inch. [Illustration FIG. 131.--Neuration of _Thecla damon_, enlarged. Type of subgenus _Mitura_, Scudder.] _Early Stages._--These have been described by several authors. The caterpillar feeds on the red cedar (_Juniperus virginiana_, Linnæus). It is double-brooded in the North and triple-brooded in the South. _Damon_ ranges from Ontario to Texas over the entire eastern half of the United States. (23) =Thecla simæthis=, Drury, Plate XXIX, Fig. 39, ♂, _under side_ (Simæthis). _Butterfly._--Resembling the preceding species, but the white band on the secondaries is straight, and the outer margins are heavily marked with brown. Expanse, .85-1.00 inch. _Early Stages._--Unknown. This species occurs in Texas, Mexico, and southward. (24) =Thecla acis=, Drury, Plate XXIX, Fig. 38, ♀, _under side_ (Drury's Hair-streak). _Butterfly._--The upper side of the wings is dark brown. The under side is shown in the plate. Expanse, .90 inch. _Early Stages._--Unknown. This very pretty species is found in the extreme southern portions of Florida and the Antilles.
