but little shorter, discal cell of fore pair slender, closed, of hind pair 

 shorter, closed, in each of the fore wings the veinlet behind the 

 third apical cell is, for the most part of its middle, divided, forming 

 a slender cell (possibly this is only an aberration). 



]Verophilus oregoiiensis n. sp. — Black, head rather densely clothed 

 with yellow hair; basal joints of antennae black, with yellow haii', rest of 

 antennae with short yellow hair, and a pale brown ring at tip of each joint, basal 

 joints of palpi pale, with yellow hair, apical joints darker; legs pale yellow, 

 intermediate and hind femora fuscous on basal half; thorax black, with yellow 

 hair: abdomen brown; fore wings rather blackish, the anal veins and the basal 

 part of the radius black, elsewhere the veins are paler, surface with black hair 

 and yellow or golden between the veins, most prominent on basal pair; hind 

 wings quite black, with black fringe, wings rather broad, discal cell of fore pair 

 slender, much longer than its pedicel, but shorter than the apical cells, fifth 

 apical and first subapical are pedicellate, in hind wings the discal cell is shorter 

 than its pedicel, and less than one-half the length of apicals, seven apical cells in 

 hind wings, all narrow at base, and radiating from the ends of discal and thy- 

 ridial cells; subapical spurs on hind and intermediate tibiae are much beyond the 

 middle. Expanse 26 mm.
