with scattered light hrown dots, some of those near the base darker brown ; these 

 dots give otr indistinct oblique clouds, gradate veinlets mostly brown, clouded to 

 form an indistinct band, border with groups of brown dots, pterostigma indis- 

 tinct. Wings rather broad, pointed at tip, costal space narrow toward base, cu- 

 bitus much bent toward post-cubitals, no connecting veinlet from upper branch 

 of cubitus to the radius or first sector, three sectors, upper branch of the third 

 forked before the inner gradate series, lower branch simple, five gradate veinlets 

 of inner series, the last beyond the next to the last, six gradate veinlets in outer 

 series, hind wings not marked, veins pale, except a few of the outer gradate ones. 

 The appendages of this species are stouter than those of H. castanx, and when 

 seen from above the inner branch is shorter. 



Two sj^ecimeiis, Olympia, Wash. [T. Kincaid]. 



Hemerobius nicestus n. sp. — Alar expanse 17 mm. Head pale, a brown 

 stripe below each eye, antennae and legs pale, thorax pale, hardly brown on the 

 sides. Abdomen rather obscure, veins of wings pale, with scattered, light brown 

 dots, dots around border, gradate veinlets brown and margined with brown, 

 pterostigma reddish in both pairs of wings. Wings rather narrow, rounded at 

 tip, costal area narrow toward base, cubitus much bent toward post-cubitus, no 

 connecting veinlet from its upper branch to the radius or first sector, three sec- 

 tors, the upper branch of third forked just before inner gradate series, the lower 

 branch is simple, six gradate veinlets in both series, the last of the inner series 

 slightly before the next to last; hind wings not marked, veins pale. 



One specimen from Olympia, Wash. [T. Kincaid]. Close to the 

 Eastern H. stigmaterus, but appears to be distinct. 



Henierobius veiiustus n. sp.— Alar expanse 22 mm. Head blackish, a 

 pale spot on the labrum and above the antennae, latter pale, thorax pale, a brown 

 stripe each side, legs pale, the abdomen fuscous, wings with pale veins and brown 

 dots, these dots often surrounded by little clouds, those on the veinlets connect- 

 ing cubiti form a large and prominent spot, and on the gradate veinlets they form 

 a continuous band, gradate veinlets brown, border of wing rather obscure, and 

 with alternating dots, pterostigma hardly distinct. Wings not broad, tip scarcely 

 pointed, costal area rather narrow toward base ; cubitus distinctly bent toward 

 the post-cubitus. but not as much as in many species, a connecting veinlet between 

 cubitus and radius at the origin of the first sector; three sectors, upper branch 

 of the third forked twice before the outer series of gradate veinlets. the lower 

 branch is simple; six gradate veinlets of inner series, the last basad of the next 

 to the last, six in outer series; hind wings not marked, the costal and some of 

 the gj-adate veinlets brown. 



One speci nen, Mt. Washington, N. H. (Mrs. A. T. Slosson). A 

 very handsome species. 



Section B. — The cubitus straight, not bent toward the post-cubitus, 

 the two connecting veinlets are thus of nearly equal length ; a veiidet 

 connecting cubitus and the first sector of the radius. 



Hemerobius disjiinctus n. sp.— Alar expanse 21 mm. Head black, 

 with two pale spots above, antennae pale, thorax pale, blackish on the sides, and 

 some dark, almost connected, spots on the middle. Abdomen blackish. Legs
