base to inner angle. Secondaries wholly light blue, color of Ly- 

 caena Pseudargiolus, pale next outer angle and along inner mar- 

 gin ; hind margin edged by a black line, preceded by a white one, 

 and on that, towards outer angle, is a narrow fuscous edging; 

 some small patches of fuscous also near inner angle along same 

 line ; in lower median interspace is a marginal black, rounded spot, 

 and at inner angle, an orange spot ; furnished with two tails, the 

 outer one short, white; the inner one very long, threadlike, black, 

 partly fringed on one side by white, white at tip ; fringes of 

 primaries fuscous, of secondaries white, not pure but a little gray, 

 and at the ends of the middle nervules darker than elsewhere. 



Under side gray-white, pale on disks, and darkest on hind 

 margins ; both wings are edged by a fine red line, and are crossed 

 a little beyond the middle by a common series of elongated red 

 spots edged with white; this series on primaries stops at lower 

 branch of median, and on inner margin of secondaries takes the 

 form of W; discal spot of primaries a long, red bar; on second- 

 aries there is a small red spot on costal margin near base, and two 

 smaller ones in line with it on middle of basal area ; primaries 

 have also a sub-marginal row of pale fuscous, sub-lunate spots, 

 and the marginal area of secondaries is clouded with light and 

 dark, not forming distinct spots ; between the tails a black tri- 

 angle upon a large orange spot, and at the angle a black spot 

 overtopped by orange ; the under side of the tail is also red next 

 the margin. 



Body above black, covered with blue hairs, the abdomen 

 white; beneath wholly pure white ; legs white, annulated broadly 

 with black on outer sides ; palpi white ; antennae annulated black 

 and white; club tipped with ferruginous. 



From I ? taken at San Antonio, Texas. So far as I know 

 this specimen is still unique. 



Thecla Ines. n. s. 



Male. — Expands .80 to .85 inch. 



Upper side wholly lavender-blue, except the apical area of 

 primaries, which is brown-black ; secondaries have a rounded 

 black marginal spot between the tails and an indistinct spot next 

 anal angle ; the posterior tail is long, and both are slender, black, 

 tipped white ; fringes sordid-white next the margin, brown at ends. 



Under side of both wings cinereous, lightest colored over 

 extra-discal part of secondaries. Under a glass the scales are 

 seen to be alternately gray and brown, but on secondaries, beyond 

 disk, the gray scales prevail, and this area is clouded, light and 

 dark; primaries have a sub-marginal line of pale brown lunules; 

 an extra-discal, nearly straight black stripe, edged on the outer 

 side by white ; a straight black bar on arc ; secondaries have an 

 irregular black line across disk, forming a W near inner margin ; 

 on the arc a black streak; a brown patch at inner angle and a 

 faint spot between the tails.
