and a ring of black scales which is not complete superiorly. Eeniform 

 large, kidney-shaped, outlined by blackish scales which do not form a 

 continuous line, an inner ring of smoky brown, leaving an annulus and 

 central lunule of the paler ground color. Claviform pointed, moderate 

 in size, outline smoky and broken. Secondaries white, with a smoky 

 outer margin, which starts as a line at the anal angle and broadens to 

 a band at the apex; veins and a small discal lunule also smoky. Be- 

 neath white, powdery, both wings with a blackish discal spot, primaries 

 with an outer line through the costal i^egion. 



Expanse, 37 mm. — 1.48 inches. 



Habitat. — Pullman, Washington (Piper). 



One male in fair condition. The species belongs probably to the 

 pitychrous series, though the median shade is traceable. There is noth- 

 ing sufficiently near to it to cause confusion, while the sharply defined 

 dusky terminal space indicates the ochrogaster type of maculation. 



i8. CARNEADES ATROPULVEREA, new species. 



Ground color dull smoky brown, densely and quite evenly powdered 

 with black scales. Head and tiiorax immaculate, collar with a faint, 

 darker, central line. Thoracic vestiture mixed scales and hair, patagia 

 not relieved, tnftiugs feebly marked, tliough evident. 1 Primaries with all 

 the markings obscure and no contrasts of any kind. Basal line gemi- 

 nate, best marked by the yellowish scales in the included space. Trans- 

 verse anterior line geminate, blackish, and with four small outcurves. 

 Transverse posterior line geminate, evenly and not greatly outcurved 

 over the cell, inner part crenulate, outer even and very feebly marked. 

 Subterminal line scarcely paler, marked by the slightly darker terminal 

 space, and an irregular, somewhat broken, dusky subterminal shading. 

 A series of small terminal lunules, followed by a yellowish line at the 

 base of the fringes. Median shade broad, blackish, diffuse, angulated 

 below the reniform and making the most obvious bit of ornamentation 

 on the wing. Olavifarm barely indicated. Orbicular obsolete, or barely 

 traceable by a few lighter scales. Eeniform moderate in size, upright, 

 kidney- shaped, vaguely defined by an incomplete yellowish annulus. 

 Secondaries even, smoky fuscous, with paler fringes and a feebly defined 

 smoky lunule. Beneath, primaries smoky, a little gray powdered, 

 secondaries gray, powdered with smoky, with a broad, smoky outer band 

 and discal lunule. 



Expanse, 37 mm. = 1.50 inches. 



Habitat. — Denver, Colorado, October 10; Fort Collins, Colorado 

 (Gillette). 



Three females, one of them rubbed and otherwise imperfect. Larger 

 and narrower winged than intrita, with all the maculation obscured 

 and the median shade unusually evident. The orbicular is almost 

 entirely obsolete and the reniform is very incompletely outlined. It is 

 to be regretted that no male was received.
