nervule, and the rest following in the consecutive interspaces. The fringe of 

 hind margin is tawny, narrow at upper angle, but broadening toward anal angle, 

 and becoming quite prominent. 



Under side of fore wing duplicates the white spots of upper surface, the low- 

 est spot showing more whitish. The apical area extending half way toward the 

 base is brown, tending to dark brick red. The interspaces just within hind margin 

 are heavily dusted with grayish scales from apex half way down to lower angle, 

 forming quite a prominent feature. The basal area is blackish. Fringe of hind 

 margin is the same as on upper surface. The white line of upper surface running 

 from end of discoidal space downward does not appear on under side. 



The ground color of under side of hind wing is brown, tending to dark brick 

 red. From the centre of costa, extending transversely across to submedian 

 nervure, is a band or area heavily dashed with grayish or whitish scales bending 

 toward base at its central portion. The transparent white spots of upper side 

 are repeated. The two interspaces toward inner margin are dusted with whit- 

 ish scales, giving an appearance of a continuation of the spots. The hind 

 margin has a fringe of tawny hairs, becoming quite prominent toward anal 

 angle. Within the margin, for upper half of wing, the interspaces are heavily 

 dusted with grayish or whitish scales. The inner margin is reddish brown, the 

 two interspaces above being blackish. 



Female. Identical with male, excepting the absence of the white line and its 

 dark ground on fore wings. 



Described from specimens taken April 5, 1899. It is very closely 

 allied to N. macareus Herr Schaff. 



Prenes californica A. G. Weeks, Jr. 1 



(Plate XXII, Figure 2.) 

 Habitat: Lower California. Expanse: 1.70 inches. 



Head, above, dark brown ; beneath, nearly white. Eyes brown, surrounded 

 by a fine line of white. Antennae black. Thorax dark brown, grayish beneath. 

 Abdomen dark brown, nearly white beneath. Legs dark brown. 



General ground color of upper surface dark brown. 



One-quarter distance from apex to base of fore wing are three minute white 

 spots at right angles to costa. In next lower interspace is a larger white spot 

 nearer to hind margin. In next lower interspace is a still larger white spot, situ- 

 ated not under the other but nearly touching discoidal space. Below this and 

 still nearer base, under the outer end of discoidal space, is another white spot,
