slender, blackish in pale specimens, hardly darker than ground in deeply colored 

 examples ; as a whole it is a little and very evenly outcurved. S. t. line irregular, 

 either a slightly paler line on an even ground, a mere contrast caused by a dusky ter- 

 minal shading or by a preceding cloud. A darker terminal line at base of fringes. 

 There is an obscure median shade, hardly traceable from costa obliquely to the infe- 

 rior portion of reniform, there a little angled and then, more obvious to the inner mar- 

 gin. Claviform and orbicular wanting. Reniform rather narrowly kidney-shaped, 

 somewhat rusty red outwardly, a little darkened inferiorly and with or without white 

 dots at the extremities. Secondaries smoky, a little paler at base, fringes luteous to 

 reddish. Beneath reddish, powdery, all wings with an extra- median line, primaries 

 with the disk smoky, secondaries with a small discal spot. Expands I.40-I.60 

 inches = 35-4° mm. 



Habitat : Glenwood Springs, Colorado, April and October. 



Three examples, all males, from Dr. Barnes, who has others. The 

 specimens were captured in 1893, 1894 and 1895, and I have kept 

 them associated with lualkeri and sidus as a color variation. To de- 

 termine which species I really had the genitalia were examined and 

 proved it distinct from either of those described and figured by me. 

 The maculation is as in the two species mentioned, but more obscure 

 than in either, and the ground color is intermediate. It is also more 

 even in appearance and the median shade is not nearly so well marked 

 as in walkeri. The genitalic structure is most like that in walkcri, 

 but lacks the accessory basal clasper and the tip of the harpe is en- 

 tirely different in shape, unlike any other in the genus.
