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

 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.

 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
