inner angle. Secondaries wholly light blue, color of Lycaena Pseu- 

 dargiolus, pale next outer angle and along inner margin ; 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 fus- 

 cous also near inner angle along same line ; in lower median inter- 

 space 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, thread like, black, partly fringed on one side by white, 

 white at tip; fringes of primaries fuscous, secondaries white, not pure, 

 but a little gray, and at the end of the middle nervures 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 secondaries 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 submargi- 

 nal row of pale fuscous sublunate spots, and the marginal area of sec- 

 ondaries is clouded with light and dark, not forming distinct spots ; 

 between the tails a black triangle upon a large orange spot, and at the 

 angle a black spot overtopped by orange ; the under side of the tails 

 is also red next to 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. 



Of this charming species I possess but a single example, taken at 

 San Antonio, by Mr. Boll. It belongs to Group III.
