the base of the tails is a tawny spot, which in some specimens is 
prominent and in others is so dim as to be scarcely noticeable. The 
under side is lighter brown than the upper, the spots arranged in two 
rows on both sets of wings much the same as in the preceding, except 
that they are farther apart and the white lines encircle the brown 
spots on the inner row, although they are much more prominent on 
the outer side. Several crescents of deep orange, edged internally 
with black, extend from the base of the lower tail to within a short 
distance of the upper angle in the lower wing, and a large blue spot 
is located between the base of the lower tail and the inner angle, 
where there is a black spot. 
Thecla edwardsii. Under side. 
The tails are black, tipped with white, and a small black spot, 
with a point in the middle extending upward, is located above the 
base of the tails. A fine black and white line follows the lower mar¬ 
gin of the wing from the black spot at the lower angle to the upper 
angle. The thorax is gray, the legs nearly white, and the abdomen 
light brown. 
This butterfly, although usually less abundant, inhabits the same 
localities and may be taken at the same time as the preceding species. 
The remarks as already written in regard to the habits of one apply 
equally well to the other. 
Another double-tailed species, which I have found rather rare and 
difficult to obtain in perfect condition, is Thecla strigosa. The upper 
side is dark brown, and in the female a large patch of tawny orange 
occupies the middle of each fore Aving. This spot is almost if not 
wholly wanting in the male. A faint taAvny spot with a black spot 
below it is placed between the base of the tails in the lower wings, 
and a black line edged with a faint line of white extends from the 
base of the upper tail to a black spot at the inner angle. The tails 
are black, tipped with white. The body is dark brown. The under
