SDinewhat i)aler, blnck iu;irsined iiiul uarrowly white riusiefl. Orbicular oval, 

 oblique, white rinjied, with narrow black margin, the centre slightly jialer. 

 Reniform uorraal, of a good size, black margined, whitish filled, with a central 

 ochery lunule. The cell between the spots is blackish, continued beneath across 

 the wing as a rather narrow blackish shade line rather close to and parallel with 

 the t. p. line. S. t. line pale, interrupted, somewhat punctiform, preceded by 

 irregularly sized and formed black spots, and followed by smaller and less dis- 

 tinct spots. A row of black terminal lunules. Fringes long, whitish, an ochery 

 line at base, and a central fuscous line. S. t. si)ace with a well marked paler 

 shade opposite cell, and again in the submedian interspace. The costal region is 

 also paler in some specimens, the transverse lines marked by distinct black spots. 

 The veins are somewhat pale marked to the t. p. line, and beyond that black 

 marked. In some specimens pale rays accompany the veins and encroach on the 

 terminal space. Secondaries whitish, with a more or less marked yellowish 

 tinge, and with a well marked black border. Fringes white or yellowish. Be- 

 neath, primaries smoky, with an outer line, distinct about half way across the 

 wing and a broad blackish outer margin. The ordinary spots are faintly re- 

 produced. Secondaries as above, hut paler. Head with black scales between 

 the antennse. Collar with a transverse black line at base and a fuscous line at 

 middle, which is sometimes wanting. Expands 1 20 — 1.35 iuches; 29—34 mm. 



Hab. — Arizona, Colorado. 



The Colorado specimens are darker in color than those from Ari- 

 zona, and the latter have the secondaries nearly white, whereas in 

 the Colorado specimens the yellow shade is distinct; the niaculation 

 varies somewhat in prominence, but is always distinct. The sj)ecies 

 is readily distinguished from its near allies by the distinctness of its 

 maeulation and the oblique orbicular. 



The genitalia of the male have the harpe as usual, the tip very 

 slightl)'' oblique, inwardly fringed with a row of very fine spinules ; 

 the clasper is from about the middle of lower margin and extending 

 about across the harpe somewhat dilated at its middle and gradually 

 narrowing to a long acute point. 



A type specimen is in the U. S. National Mu.seum collection (coll. 

 J. B. Smith) ; other specimens in various collections.
