APATURA I. 



Leilia differs from the other mem])ers of its group, in that the black marks in 

 the cell of primaries, which in Celtis and Alicia are three in number, two of 

 them being in the middle of the cell, on the sub-costal and median nervures 

 respectively, and placed obliqueh- to the nervures and parallel to each other, 

 are here reduced to two, owing to the centi-al marks being united in one straight 

 bar, perpendicular to the nervures. These Ijars are also separated by a white 

 space, which is not the case in the allied species. A similar arrangement of the 

 bars is seen in Clylon, except that in this the inner bar is usually sinuous in- 

 stead of .straight, cau.sed by the joining of the two oblique marks at their ex- 

 tremities. There are three ocelli on primaries of Leilia, as .sometimes happens 

 with Cdtis, but in the former they contain eccentric patches of blue scales, as 

 do also several of the ocelli on .secondaries, a peculiarity observed in neither 

 Celtis nor Alicia. On the under side the two lower ocelli on primaries contain 

 similar blue patches, and the uppermost one a patch which is partly blue, partly 

 white. The spots on the disk on upper side are white and distinct. The color 

 of this side is nearly that of Alicia, of the under side diflerent from either that 

 or Celtis, the basal part of primaries being castaneous, instead of light gray- 

 brown, and the remainder of both wings chiefly of a pearl-gray, suffused toward 

 the hind margins with pale blue. In CcUis the prevailing hue is gray-brown, 

 .sometimes wholly pink-tinted, and of Alicia gray-white, tinted with purple. The 

 antenna} also are ferruginous above and below, with the slightest indications of 

 annulation near the base ; these organs in CcUitt are fuscous above, yellow 

 beneath, and the fuscous portion is distinctly aniudated with white from ba.se 

 to club. 



I regret having to figure this species without being able to give both sexes, 

 as I aim to do in every case, but the difficulty of ol^taining the butterflies of 

 Arizona is so extreme that years might elapse before I should receive another 

 example.
