Body almost black, bluish reflections faint. Membranes at 

 base of fore wings pale, often almost white. Uncus 

 viewed in profile arched at top, and usually with distal two

putnami var. keddiensis new variety. 

 EE. Body black with brassy or greenish reflections. Fore femora 

 almost entirely chestnut colored. Membranes at base of 

 fore wings pale, often almost white. Vein separating radial 

 cell from ulnar cells usually pale throughout its length. 

 Uncus viewed in profile arched at top, distal two thirds of 

 lower line not straight but curved so that the extremity 

 sometimes appears bent downward. Front of head usually 

 quite hairy. Expands from 48 to 54 millimeters. Occurs 

 in British Columbia, Washington, Oregon, California, 



Idaho, Montana areolata (Uhler). 



Uncus viewed in profile arched at top but more suddenly 

 declivitous near the tip than in areolata ; distal two thirds 

 of lower line straight or nearly so with a subapical sinu- 

 ation. Veins of fore wings almost entirely pale, except 

 those surrounding the first and second ulnar areas, and the 

 first seven apical areas, which are black or nearly so. 

 Expands from 40 to 44 millimeters. Occurs in California. 



similis new species. 



Uncus when viewed in profile evenly arched at top, and with 



lower line straight for part of its length before the hooked 



extremity. Hairs on front of head long and conspicuous. 



Costal margin of fore wings chestnut colored. Expands 45 



millimeters. Occurs in Texas falcata new species. 



BB. Small, expanding about 38 millimeters ; uncus when viewed from above 



broadly ovate. Fore wing 17 X 6.5 mm. 



Uncus when viewed from above '" nearly as broad as long, with its 



apex subacute." Last ventral segment in female with notch broadly 



V-shaped. Membranes at base of fore wings pale orange. Expands 



about 38 millimeters. Occurs in California aperta Van Duzee. 



AA. Fore wings much broader, the breadth being equal to about one half the 

 distance from the basal cell to the apex of the wing. 

 Uncus when viewed from above broadly lanceolate and subacute at apex, 

 its width almost half the length. Last ventral segment in female with 

 notch more narrowly V-shaped than in aperta. Membranes at base of 

 fore wings orange. Expands about 36 millimeters. Occurs in California 



and Nevada vanduzeei new species.
