third and fourth median nervules ; an elongated anal spot and a 

 minute transverse spot on the^|'submedian vein, near the base. The 

 middle subcostal spot is supplemented below the median vein by a 

 very faint transverse streak. Fringes concolorous with wings. 



Secondaries dirty white, thinly scaled, rosy along the inner margin; 

 with a small blackish discal spot ; a submarginal row of three blackish 

 spots, the anal one small, the apical one extending from the costa to 

 the 1st median nervule. There are also two marginal spots, one near 

 the apex, the other about the middle of the inner margin. 



Beneath as above, except thatjthe fore wings are nearly white, and 

 the costa of all the wings is decidedly yellow ochre. 



Expanse of wings, 1.60 inches ; length 0/ body 0.65 inch. 



Habitat. — Arizona, (coll. Stretch). 



Described from one S , for which I am indebted to my friend 

 Mr.W. H. Edwards. The nearest ally of this beautiful species is A.autho- 

 lea, Boisduval, which it much resembles. The number and location 

 of the black markings on the primaries is identical, but they are much 

 reduced in size (pi. 3, figs. 7, 8). The chief point of difference is in 

 the black markings on the secondaries of which there is no trace in 

 A. autholea 5 , while it may prove, however, to be merely a variety 

 when we possess longer suites of these insects ; it is at present suffi- 

 ciently distinct to warrant a separate name.
