Upper side uniform brownish-black. Primaries with a small, 

 oval, grayish shining spot on the disk of the males. Secondaries 

 terminated by two small tails, a little whitish at the extremity, of 

 which the internal one is much the longer. At the base of these 

 tails, near the fringe, there is a small grayish-white line, sometimes 

 preceded by an indistinct fulvous spot. 



Under side ashy brown, with a short, geminate, bluish ray on 

 the disk of each wing. The primaries are traversed by two small 

 rays of bluish-white, shaded with brown on one of their sides, of 

 which the exterior is indistinct. The secondaries are traversed by 

 two similar rays which form an angle towards the abdominal edge. 

 Between the tails there is a fulvous spot, bordered with black on 

 the outer side, followed by one or two small spots of the same 

 color — an ashy blue space, bordered with a black spatule. The 

 anal emargination is also bordered with fulvous ; a small white 

 marginal line at the fringe. 



Body, like the wings ; breast, with some bluish hairs ; abdomen 

 whitish. Antennae blackish, with white rings ; club blackish. 



Larva, which feeds on Crataegus, pale russety ; a little greenish 

 on the sides, which are marked with oblique brown streaks ; a 

 wide brown band on the back, which disappears on the middle 

 rings, where it is replaced by two parallel brown lines; the brown 

 band reappears on the posterior rings. 



Chrysalis yellowish-brown, powdered with brown atoms. 



Southern States. — Expands a little over an inch.
