OF WASHINGTON. 81 



pointed, hind margin flattened and slightly concave before tip, basal half 

 of costal area rather narrow; hyaline, with pale brown markings, those in 

 apical portion of wing more or less coalescent and forming on each gra 

 date series an oblique streak; pterostigma indistinct, pale; an indistinct 

 pale line bisects the costal space longitudinally through the bases of inter 

 costal forks; veins pale, with numerous brown interruptions, those on 

 radius and cubitus most pronounced ; each brown spot on the longitudi 

 nal veins between radius and hind margin gives off an oblique pale brown 

 mark each side, thus forming several series of V-shaped markings, the 

 angle of the V's pointing inward; gradate veins almost wholly brown ; 

 hind margin of wing brown, interrupted with pale spots; posterior fork 

 of median vein strongly bent toward the cubitus, thus making the inner 

 veinlet connecting it with the cubitus much shorter than the outer ; radio- 

 median cross vein situated at least as far before the forking of the median 

 as the former is long and joining radius much before origin of first sector ; 

 three radial sectors, anterior branch of the third forked before the inner 

 gradate series and before the subpterostigmal radial cross vein, posterior 

 branch simple; five gradate veins in inner series, the last beyond the next 

 to the last, seven or eight in outer series (seven in left wing, eight in 

 right wing, in the type specimen). Posterior wings hyaline, unmarked; 

 the veins pale, tinged with reddish brown, some of the gradate veins 

 darker; the first fork of radial sector plainly before forking of median.
