subterminal line lost in the general diffusion of the markings or indicated by 
black inner markings; white spot above tornus distinct, but not contrasted, 
resembling the white about the discal mark; terminal line black, crenulated, re- 
ceding from the margin. Hind wings rather light gray, with faint discal spot 
and outer line. Expanse ¢ 40 mm., 2 45 mm.” 
The type specimens were received from Dr. Barnes and besides a 
2 co-type there is a series of both sexes in the Barnes collection. The 
species appears to us to probably represent a local race of plagiata 
WIk., but for the present we keep it distinct. 
Hasitat. Glenwood Springs, Colo., (July 8-30, Aug. 16-23). 
O. styx B. & McD. (PI. V, Figs. 3, 4). 
Olene styx Barnes & McDunnough, Psyche XVIII, 150, Pl. XIII (1911). 
“Primaries deep black-brown; all traces of maculation practically lost with 
the exception of an obscure black basal dash, a large reniform very faintly out- 
lined in whitish and a small white spot above anal angle. Secondaries deep 
smoky, in the 2 with outer margin concave below apex, in the male well 
rounded. Beneath smoky with faint traces of discal spots on both wings. 
Expanse ¢ 32 mm. Q 36 mm. 
Hasitat. Duncans, B. C. (Hanham) 1 ¢,1 @. Types, Coll. Barnes.” 
We are inclined to think this will prove to be a melanic form of 
O. plagiata Wk. or one of its races. We have an exactly similar 3 
from New Brighton, Pa., (July 2) (Merrick). In the event of our 
supposition being correct, sty would then bear the same relation to 
plagiata that montana Beut. does to manto Stkr. Breeding however 
will be necessary to decide the question.
