14 AMERICAN NEUROPTERA. 



apical spurs are beyond end of second third ; in middle tibiie the subapical spurs 

 are plainly before middle and scarcely more than their length beyond base. Ex- 

 panse 20 mm. 



Several specimens from southwestern Colorado, July 16th (Oslar). 



Hydropsyche hageiii n. sp. — Head black, some brown hairs on face, 

 grayish white above, a tuft of brown hair each side behind near eye, palpi 

 brown; aiitennfe pale, spiiwlly annulate with brown; thorax with whitish hair 

 in the middle, and a large tuft of long, brown hair each side at base of the fore- 

 wings; abdomen pale on base, brown toward tip; legs pale, rather darker toward 

 tips, especially in anterior pair. Wings brown, darkest along the veins, irrorate 

 with white, pterostigma brown, and a dark brown spot near upper tip of the first 

 apical cell ; hind wings gray hyaline, brown on tip. Male has eyes large, and 

 scarcely their diameter apart. On the middle legs the preapical spurs are a little 

 nearer to base than to tip, on the hind legs the preapical spurs are nearly twice 

 their length before the tip. Wings much like H. scalaris. Expanse 17 mm. 



Several specimens from Falls Church, Virginia. Readily sepa- 

 rated from H. scalaris by the large eyes of the male. 



Hydropsyclie slossonse n. sp. — Head brown, with a transverse brush 

 of brown hair just below base of antennae, vertex with gray hair, and a tuft of 

 brown each side behind; palpi brown; antennge pale, spirally annulate with 

 brown; thorax black, mesoscutellum yellowish, some pale hair in middle, dark 

 at bases of wings; abdomen black above, brown below ; legs pale, rather darker 

 on the tibite. Wings brownish, densely irrorate with whitish, the larger brown 

 patches being along the apical margin ; hindwings grayish. In the male the eyes 

 are fully one and one-half their diameters apart. On the hind tibia the preapi- 

 cal spurs are at the base of the outer third ; on middle tibia they are much nearer 

 to the base than to tip, in fact only about ther length from the base. Wings 

 rather long and slender; first apical cell twice as long as its pedicel, fork 3 with 

 a pedicel more than twice as long as pedicel of fork 2. Expanse 22 mm. 



One pair from Franconia, New Hampshire (Mrs. Slosson). 



Hydropsyche cockerelli n. sp.— Head brown, with a transverse brush 

 of brown hair below base of antennae, vertex with whitish hair; palpi pale 

 brown, tips paler ; antennae pale, spii-ally annulate with brown; thorax black, 

 pale hairs in middle of mesothorax, aV)domen dull black above, brown below, 

 genitalia yellowish, with a black spot near the middle of each lower appendage; 

 legs pale yellowish. Wings brown, darker on anal region than elsewhere, 

 densely irrorate with small yellowish spots; hind wings grayish, fringe blackish. 

 In male the eyes are a little more than diameter a])art. In the hind legs the 

 preapi(;al spurs are at the base of the outer third on the tibia, on the middle legs 

 the preapical spurs are somewhat before the middle of the tibia, but plainly 

 more than length from the base. Forewings of moderate length, first apical cell 

 fully twice the length of its pedicel, fork 3 with a jiedicel scarcely twice as long 

 as that of fork 2. Expanse 23 mm. 



Several specimens from Pecos, New Mexico, June 26th.
