AMERICAN LEPIDOPTERA. 65 



scured from the mesial band to base so as to render the blackish mark- 

 ings indistinct as compared with Hesperis, the nearest allied species ; 

 margins bordered by two parallel lines that are confluent on primaries 

 and on upper half of secondaries, forming a black band through which 

 faintly appears a tint of fulvous in the interspaces ; on this band rests 

 a connected series of black lunules enclosing pale fulvous spots; the 

 other black markings as in Hesjjeris, but heavier; on disks of second- 

 aries paler spots corresponding to the second row on underside ; the 

 black markings in cell of primaries next anterior to the spot on are 

 strongly bent so as to enclose a sub-quadrate space which is paler than 

 the ground color ; fringes luteous, black at tips of all nervules. Under 

 side of primaries cinnamon brown at base and up to the mesial black 

 band and within the P like spot on the arc ; but the sub-quadrate 

 space and that portion in cell next posterior is bun ; rest of wing bun , 

 including the sub-marginal and sub-apical spots. 



Secondaries reddish-brown from base to outside of second row of 

 spots, the band between this and outer row buff and immaculate ; the 

 marginal spots large, broad, sub-triangular, very slightly edged above 

 by brown ; tbose of second row mostly large, broad-oval ; of the third 

 row, the first on costa is nearly round, the second trapezoidal, the third 

 a dash only ; the spots of the second and third rows lightly edged 

 above with black ; two round spots in black rings in cell, a long oval 

 at base cf sub-median and a dash at base of sub-costal ; all these buff, 

 scarcely differing from parts of the ground color, and without silver. 



Body covered with fulvous hairs, grey buff beneath, abdomen buff; 

 legs buff, palpi same, fulvous in front and at tip ; antennae black above 

 fulvous below ; club black, tip fulvous. 



Female. — Expands 2.7 inches. Upper side paler, the general ap- 

 pearance more that of an Euptoieta, the whole outer portion of the 

 wings, including the sub-marginal spots and the discal spots of second- 

 aries faded to a whitish ochraceous ; in cell of primaries the space 

 within the P and that between the two black lines next base deep 

 orange fulvous, rest of cell of same shade as the disk, the subquadrate 

 space conspicuous ; under side of primaries orange fulvous instead of 

 cinnamon-brown ; secondaries next base pale brown mottled with buff, 

 the spots shaped as in male but greatly enlarged; on the submarginal 

 spots of secondaries may be seen a few scales of silver. 



From a pair belonging to the collection of James Behrens, Esq., of 

 San Francisco, and taken at Downieville, California.
