Hub. — Ft. Collins, Colorado (Gillette); Glenwood Springs, Colo- 

 rado (Barnes); New Mexico ; Pierre, South Dakota (Truman). 



Five examples, only one of which is a male. Compared with the 

 preceding, the present s|)ecies is much more gray, the white costal 

 shading much more broken up and never extending below the 

 median vein. The tendency here is to a round, solid gray reniform, 

 three of the five specimens being so marked. 



The venation of the secondaries is [)ractically as in flavicosta.

Head and thorax bluish pale gray, varying toward yellowish in some cases. 

 Abdomen yellowish pale gray. Primaries creamy or bluish gray in basal space 

 and along costa to t. p. line. T. a. line a broad, inwardly oblique brown or black- 

 ish band, which does not cross the costal region. Median space bluish or violet- 

 gray ; outer portion above, blackish powdered before t. p. line ; below with a bright 

 rusty red-brown half band, anteriorly defined by a white median line which 

 does not extend above the middle, outwardly by the t. j). line. T. p. line an 

 oblique white mark on costa, defined by a blackish shading opposite the cell, 

 deeply incurved and whitish below the middle of the wing. S. t. space more or 

 less brown shaded, tending to luteous toward the hind margin on which rests a 

 violet shade. S. t. line indefinite. A series of black terminal dots on the veins. 

 Orbicular a small black dot or wanting. Reniform large, with a vague smoky 

 outline, else concolorous. Secondaries yellowish to smoky, with con<"olorous 

 fringes. Beneath, primaries tawny, with a smoky disc. Secondaries paler, with 

 a narrow smoky median line which may be obsolete. 



Expands 25-27 mm. -= 1.00-1.08 inclies. 



Hab. — Massachusetts; New York ; New Brunswick, New Jersey, 

 August 18th ; Illinois in August. Probably occurs throughout the 

 Middle and Central States. 



Three specimens only are at present under examination ; but I 

 have seen many others that did not differ essentially in appearance. 

 The variation is chiefly in the differences of shade of the lighter por- 

 tions of the wing, and this ranges from almost white to decided 

 cream yellow in one direction, to almost violet in the other. 



The body is, on the whole, more robust than in its allies, and the 

 wings are a little broader. The inner margin is sinuate and the 

 hind angle is a little drawn out or produced. On the posterior wing 

 the 3rd and 4th veins arise from the end of the cell and 5 arises 

 from a little spur, clo.se to and as strong as the submedian.
