along costal edge of primaries, but the bases of both wings are 

 quite free from black ; a broad black border along the hind mar- 

 gins ; on primaries this presents a deep, broad, sub-quadrangular 

 sinus, covering the two median interspaces ; the base of the sinus 

 is uneven, with a further small excavation in the border; above 

 the sinus the inner edge makes obliquely and with wavy outline 

 for costa, which it strikes at about two-fifths the distance from 

 apex to base ; the border of secondaries has a projecting tooth 

 opposite cell. 



Under side of both wings paler, more white, but the cell and 

 costa of primaries decidedly yellow ; a slight sprinkling of dark 

 scales along costal edge, and the ends of the nervules to apex are 

 dotted black ; also towards apex and on upper half of hind mar- 

 gin there is a little ferruginous along the edges ; on upper end of 

 arc of cell a black dot. 



Secondaries have a little cluster of ferruginous scales on costa; 

 a dash of ferruginous, with scales behind it, from outer angle half 

 across wing, and in line a mark of same color in lower median in- 

 terspace ; on costal edge a few dots, and one on upper end of arc. 

 This description applies to two males taken by Mr. Doll, but the 

 third differs somewhat ; the basal half of secondaries is lightly 

 flecked with ferruginous streaks; in the lower median and in the 

 sub-median interspaces, close to the nervule, and in the line of 

 the ferruginous dash, are two little black points, and half way 

 between the dash and hind margin are two points not so black; 

 one in each of the two upper median interspaces; the ferruginous 

 scales behind the dash are more densely laid on, and over a larger 

 area than in the other males ; otherwise, on both surfaces, this ex- 

 ample resembles the other two. 

 Female. — Same size. 



Color of primaries whitish, but yellow next base and over 

 cell to costa; secondaries all yellow, but paler than male; both 

 margins at base dusted black ; the border as in male, with a sim- 

 ilar sinus. Secondaries have no border, but the nervules at outer 

 angle are edged black, next to margin ; discal spot of primaries 

 obsolete. 



Under side of primaries nearly as upper, but deeper yellow 

 at base and on cell ; costa and apex dusted ferruginous ; the 

 discal spot distinct. 



Secondaries wholly dusted with ferruginous ; the marks as in 

 male. 



From 2 <? I ? , taken in southern Arizona. I have also one 

 male, formerly received from the Wheeler expedition. The de- 

 scription of the female answers very well to Felder's. No male 

 seems to have been hitherto described, though Kirby, in Cata- 

 logue, gives 6 Damaris as synonym of Mcxicana ? Bois. Spec. 

 Gen. 655. I have carefully compared that description with 

 Damaris ? and it is not possible that the two are identical". Nor
