outward curve to hind margin 5 the line on close examination is gemi- 

 nate. T. p. line crenulate, narrow, single; its course parallel with the 

 outer margin. S. t. line very faint, irregular, punctiform. Two longi- 

 tudinal black dashes cross the line opposite the cell and terminate at 

 outer margin. Claviform short, distinct, dark, but somewhat indefinitely 

 outlined. Ordinary spots indistinctly outlined, concolorous with costa, 

 faintly centered with darker scales. All the veins are more or less 

 evidently marked with black scales. Secondaries blackish, towards 

 base paler. Beneath smoky, powdery, all wings with discal spots. 

 Secondaries paler with a distinct extra discal dark line, beyond which 

 the wing is as dark as on i)rimaries. Head and thorax like primaries ; 

 patagia' with considerable red intermixed. 



Expands, 37"""; 1.50 inches. 



Habitat. — Arizona. 



Well defined by the dark color and unusually broad wings; there is 

 a suggestion of herelis or allies in the habitus that is at first mislead- 

 ing. The simple S antenuie are decisive.

Dark, smoky brown, or blackish ; base, costal space, and all beyond t. 

 p. line paler, more luteous, strigose. T. a. line outwardly curved be- 

 tween veins, not traceable above median vein. T. p. line continuous, 

 narrow, slightly crenulate, its course parallel to outer margin, S. t. line 

 punctiform, the dots elongate, whitish, outwardly marked by black 

 dashes; three opposite cell most distinct, and narrowly continued to t. 

 ]). line. Claviform short, concolorous, distinctly outlined. Orbicular 

 elongate, narrow, longitudinal. Eeniform upright, normally formed. 

 The spots pale, narrowly outlined in black; center slightly darker lute- 

 ous. Secondaries smoky, paler toward base. Beneath as in the preced- 

 ing species. Head dark, thorax, and especially the patagia^, sprinkled 

 with reddish. 



Expands, 29-33"""; 1.15-1.30 inches. 



Habitat. — New York(?), Arizona, Texas. 



Two specimens of this species, both males, are before me ; the type, 

 said to be from New York, is larger and somewhat sordid in appear- 

 ance — evidently not fresh ; the second is from southwestern Arizona, 

 is smaller and very distinctly marked — evidently fresh. The $ geni- 

 talia are absolutely alike in the specimens, and I have no doubt they are 

 identical, but I do doubt New York as the correct locality for the type. 

 I believe that in this case Mr. Morrison has made a mistake. This 

 species is very Wke procUvis, but is yet undoubtedly distinct. Dr. Har- 

 vey's type was evidently much like ray Arizona specimen. There is no 

 mistaking the species.
