From three male specimens from Colorado; two in coll. of 

 author and one in coll. Dr. Strecker.

E. nais Dru. (^. — Thoracic vestiture shaggy. Head and collar above 

 pale ocher-yellow, rarely with iwo black spots on the collar; thorax pale 

 ocher-yellow, with three black stripes; abdomen same color with a broad 

 dorsal black band, broadest centrally. Below, nearly entirely black; 

 fore wings black, with pale ocher-yellow marks; when complete, these 

 are as follows: a costal line from base two-thirds length of wing ( but the 

 costal edge is black), a median band from base to end of cell, where it is 

 bent at right angles to touch costal band, and sends off at its middle below 

 a branch to internal angle; a terminal W-shaped mark, the upper limb of 

 which does not quite attain costa; its central angle joins the angle of the 

 median band, and its lower limb the branch at about the middle of the 

 latter; the fringe and internal margin are also pale ocher-yellow; usually 

 the outer part of these marks is more or less obsolete, and the W tyark 

 and branch of median band may be entirely absent; hind wings pale ocher- 

 yellow, shading to darker at the central basal area, rarely overspread with 

 a light red shade in this portion. There is one marginal, three submar- 

 ginal, an elongate apical, and one small discal spot, all variable in size, 

 sometimes partly absent, or enlarged and confluent. E.xpanse 32-39 mm. 



Female differs from (J' in the smooth thoracic vestiture; the marks on 

 the collar are more generally present than absent; the color of hind wings 

 and abdomen is a darker ocher, and the marginal black spots tend to be 

 larger becoming confluent, and occasionally forming a complete black 

 border. Expanse 32-35 mm. 



E. phalerala Harris. — Thoracic vestiture of (J smooth and even, ot very 

 slightly shaggy; the black marks on collar and thorax distinctly present. 

 Abdomen pinkish red with dorsal black stripe; below entirely black; fore 

 wings black, with pale ocher-yellow markings, with a slight flesh-colored 

 tint. The pattern is as in nais, but the costal edge is yellow, and the 

 markings never show a marked tendency to become obsolete. The costal 

 band extends almost to the apex and the upper limb of W mark joins it; 

 rarely it is disconnected and shortened, but this is the extent of variation; 

 hind wings pale ocher-yellow, pinkish red along abdominal margin; the 

 color fades away outwardly, but often largely overspreads the wing; black 

 marks as in nais, but the discal dot is usually larger, while the spots do
