LYC^NID^. 201 



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 a^^art and the white lines encircle the brown 

 spots on the inner row, although they are much more prominent on 

 the outer sitle. 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 Theda strigosa. The upper 

 side is dark brown, and in the female a large patch of tawny orange 

 occupies the middle of each fore wing. This spot is almost if not 

 wholly wanting in the male. A faint tawny 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
