Name, Location and Description

From Davis’ key to Okanagana1:

A. Male uncus not hooked at the extremity, sometimes sinuate.

B. Expanse of fore wings more than 50 mm.

C. Base of fore and hind wings orange-red more or less variegated with black.

DD. The outer edge of the front wing of a more continuous curve. Medium-sized species, except schaefferi, which is large.

EE. Legs, especially the front pair considerably blackened.

F. Shining species with rather broad wings, and the hind margin of pronotum orange or reddish.

Of a slightly blueish tint, otherwise colored about as in the last species, but the costal margin of the fore wings to the end of the radial cell often bright orange, the basal cell clouded sometimes blackened. Pronotum usually plainly edged with orange on sides as well as on hind margin. Head not as blunt when viewed from above as in occidentalis, proportionately narrower and with little hair behind the eyes, also less hairy beneath. The last ventral segment of the female not doubly notched, or the second notch but feebly indicated. Expands about 60 mm.
