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 sealed, 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 first 

 median nervule. There are a^o two marginal spots, one near the apex, the 

 other about the middle of the inner margin. 



Beneath as above, except that the fore wings are nearly white, and the 

 costa of all the wings is decidedly yellow-ocher. 



Expanse of wings, 1.60 inches. Length of body, 0.65 inch. 



Hah. — Arizona. 



Described from one <f received from my friend Mr. W. H. Edwards. 

 The nearest ally of this beautiful species is A. autkolea, Boisduval, which it 

 much resembles. The number and location of the black marking's in the 

 primaries is identical, but they are much reduced in size. The chief point 

 of difference is in the black markings on the secondaries, of which there is 

 no trace in A. autholea J , while it may prove, however, to be merely a 

 variety when we possess larger strifes of these insects. It is at present suf- 

 ficiently distinct to warrant a separate name.

5 . — Head clothed with long black hairs. Thorax black, lemon-yellow 

 outwardly. Abdomen black both above and beneath, denselv and finely 

 scaled, with an indistinct lateral row of crimson dots. Anal tuft silky, 

 pale ferruginous. Legs black ; anterior pair with crimson coxae ; in the 

 middle pair the tips of the tibia? and the femora are likewise crimson ; on 

 the hind pair the tips of the tibia? and ends of the tarsi are also of the same 

 color. 



(Note. — The specimen from which this description is drawn has been 

 pressed as flat as a botanical specimen, and the body parts do not admit of 

 a more detailed description. The antenna? are wanting.) 



Anterior wings velvety black, with very narrow fringes and markings 

 as follows of clear lemon-yellow : five angular costal spots, of which the 

 two nearest the base are quadrate ; the third at the middle of the wing is
