Group III. — Four sectons. 

 Here belong two described species, H. loiigifrons Walk, and H. 

 alternatus Fitch, and a new species below. 



Ileiiierobiu!>» fl<lelis n. sp. — Alar expanse 14 mm. Head and thorax 

 fuscous, antennae and legs pale; wings broad, broadly rounded at tips, costal 

 space very broad, radius and subcosta farther apart than usual, and connected 

 toward the base by two veinlets: four sectors, the fourth arising beyond the 

 middle of the wing, forked once before the outer series of gradate veinlets, other 

 sectors simple, first connected near base to the radius, cubitus forked at usual 

 place, the lower branch straight not bending toward the post-cubitus, upper 

 branch connected to the first sector, the lower to post-cubitus and continued across 

 to the post-cubital sector, each side of equal length ; five gradate veinlets in inner 

 series, last one basad of the next to last ; seven or eight gradate veinlets in outer 

 series; second post-costal cell closed. Wings hyaline, veins pale, scarcely dotted^ 

 gradate veinlets mostly fuscous, a fuscous band across wing from within pteros- 

 tigma through gradate veinlets, and mostly fuscous beyond the second series of 

 gradate veinlets ; hind wings with an indistinct fuscous band across the middle. 

 and another just beyond the outer gradate veinlets, leaving a narrow, pale. ap;cal 

 margin. Abdomen blackish. 



One specimen, Gowanda, N. Y., June 25 [E. P. Van Duzee]. 

 TRICHOPTERA. 



LiinnephiluN ornatuM n. sp. — Length 20 mm. Head yellowish, clothed 

 with whitish hair, antennte and pal]n yellowish, with black hair on the former, 

 thorax reddish, with whitish and some black hairs. Abdomen greenish, legs pale 

 yellow, with black spines, black dot 071 trochanter. Wings hyaline, marked with 

 silvery and fuscous, costal space without marks, a somewhat silvery stripe below 

 the radius, behind this the disc is fuscous to the post-cubitus, a prominent silvery 

 stripe in the thyridial area not reaching the anastomosis, another stripe in the 

 base of the first subapical cell, a long one in fifth, and much shorter ones in bases 

 of third and fourth apical cells, a long silvery stripe behind the post-cubitus, and 

 the basal and anal region with some silvery hairs; basal joints of antenna", about 

 once and a half longer than broad ; about nine spines basad of the subapical 

 spurs on the hind tibia;, other tibije thickly spined to base ; anastomosis somewhat 

 oblique, first subapical on thyridial three times as far as the first apical on discal 

 cell, veinlet at base of the subapicals oblique, in hind wings the fourth apical 

 cell is plainly nan'ower at base than the second, in one specimen the third aj>ical 

 is divided. 



Two females, one from Sherbrooke, Canada (L'abbe P. A. Begin) ; 

 the other from Franconia, N. H. (Mrs. A. T. Slo.sson). In one 

 specimen there are a few pale spots in tips of the apical cells, and a 

 fuscous dot in the base of the thii'd one. 



Anabolia tinicolor n. sp. — Length 2.5 mm. Head and thorax ferruginous, 

 clothed with yellowish hair; antennpe reddish yellow; legs yellowish, witii l)lack 

 spines, black dot on the trochanter; wings are uniform luteo-hyaline, clothed
