28 AMERICAN NEUROPTERA. 



and a dark point in the base of the third apical cell ; hind wings paler; palpi 

 slender, basal joint of antennsB once and a half longer than broad ; spurs 1, 3, 4. 

 subapical pair on hind tibis about half the distance to apical pair; about seven 

 spines basad of subapical spurs on the hind tibiae, other tibite thickly spined to 

 the base, a few at tips of femora. Wings moderately long, not very much rounded 

 at tips, discal cell fully twice the length of its pedicel, third apical cell but 

 slightly indents the anastomosis; first apical cell is longer on the discal than the 

 fifth apical on the thyridial, veinlet at base of second subapical cell is very ob- 

 lique; apical cells long, about of equal width at base; in the hind wings the 

 fourth apical cell is as broad at base as the second apical cell. 



One female, Skokomish River, Washington (Trevor Kincaid). 

 The species of this genus, four in number, can be separated by the 

 following table : 



1. Thorax blackish above 2- 



Thorax yellowish above - 3. 



2. Wings uniform fuscous ilioilesta. 



Wings mottled biiiiaciilatH. 



3. Wings uniform yellowish, no stripe on thorax tinicolor. 



Wings faintly mottled, black stripe on thorax COnsocia. 



Halesus niinutus n. sp. — Length 9 mm. Head and palpi yellowish, with 

 a few whitish hairs; antennae fuscous, basal joints yellow ; thorax honey-yellow. 

 Abdomen dark above, except at base, pale beneath. Legs pale yellow, with black 

 spines, black dot on trochanter. Wings hyaline, pale yellowish toward base, 

 clouded with fuscous on the anastomosis, on veinlet at bases of subapical cells, 

 and along the tips of some of the apical veinlets, a dot in base of third apical 

 cell ; veins yellow ; basal joints of antennae quite widely separated, nearly twice 

 as long as broad; spurs 1-3 3 (but one of the apical pair to each hind tibia is 

 wanting so apparently 1-3-2) ; two spines basad of the subapical spur on hind 

 tibia, other tibiae sparsely spined to base; wings moderately narrow, veined as in 

 typical HdlesHS, save that the first subapical cell is barely twice so far on the thy- 

 ridial as the first apical on the discal cell, and the veinlet at the bases of subapical 

 cells is more oblique than usual, the apical cells are all of about equal width. 



One specimen, Colorado, sent by Mr. C. F. Baker. 



Enoicyla iiicerta u. sp. — Length 8 mm.; alar expanse 14 mm. Black, 

 tips of the femora, the tibiae, and bases of the hind tarsi yellowish ; wings black- 

 ish, black veined, with black bristles on the veins, surface sparsely clothed with 

 black hair, a faint hyaline spot at the arculus; hind wings are grayish with a 

 blackish fringe. Legs with small black spines; spurs 1-2-2, discal cell nearly as 

 long as the pedicel, closed obliquely beyond the anastomosis ; first api(^al cell acute 

 at base, fifth not reaching the anastoiiiosis, the others nearly equal at base ; radius 

 curved at the pterostigma; subcosta ends in a cross-vein in front of the pteros- 

 tigma; in the hind wings the first apical is long pedicellate, and the fifth does 

 not reach the anastomosis. 



One from Sherbrooke, Canada, May (Begin) ; one from Franconia, 

 N. H. (Slosson), and several from Sea Cliff, N. Y., April.
