4 AMERICAN NEUROPTERA. 



beyond brownish, pronotum dull black, rather paler on sides; thorax black; 

 abdomen brown, pale below, toward tip it is yellowish ; setae dark brown ; legs 

 dull brown, darker at tips of joints and on the tarsi; wings grayish hyaline, 

 venation brown. Thorax but little narrowed behind, angles acute, rug((sities 

 not very strong. Wings rather long, radial sector forked two or three times 

 beyond anastomosis, the first some distance out from cross-vein. Ventral plate 

 of female reaches scarcely one-half way across the next segment, and is rather 

 deeply emarginate in the middle; the last segment of the male shows a raised, 

 rather transverse white spot, slightly angulate in front. Length, 9 , 32 mm. ;% , 

 24 mm. 



One pair from Black Mountain, North Carolina, June (Beuten- 

 niiiller). • 



Perla Talidst. n. sp. — Head pale yellow, ocelli black, clypeus dusky, each 

 side margin black; antennte pale yellowish; palpi brown ; pronotum pale dull 

 brown, a narrow, median yellowish stripe; thorax pale brown, a yellowish spot 

 each side near base of wing; abdomen brownish above; venter and sternum pale 

 yellowish ; setse pale yellow ; legs pale, a black mark at tips of all femora, barely 

 darker at tips of tibiae, the apical part of tarsi black. Wings grayish hyaline, 

 venation pale brown. Ocelli forming a triangle rather broader than high, the 

 posterior ocelli a little nearer to each other than to the eyes; pronotum much 

 narrower than the head, slightly narrowed behind, moderately rugose each side. 

 Wings rather long and narrow, radial sector with four branches (counting one 

 from the anastomosis), median cell with seven cross-veinlets. Length 24 mm. 



One specimen from Wayneville, North Caroline, July (Sherman). 



Raphidia occulta n. sp. — Head shining black, mouth region pale, a 

 long narrow, median, red scar behind, the lateral scars not very plain; antennae 

 dark, basal joint dark above, next two or three pale. Pronotum reddish on 

 anterior half, black behind, with three pale stripes; rest of thorax black, with 

 red spot on metascutellum ; abdomen black, tips of segments pale, especially on 

 venter; legs pale. Wings hyaline, pterostigma yellow-brown, veins biown. 

 Head with posterior sides barely convex, with a moderately long neck; jirono- 

 tum rather slender. Wings with four cells below the pterostigma, the second 

 acute at base, and often pedicellate; the pterostigma quite long, extending to 

 tip of cell below. Male genitalia with the upper median piece broader at tip 

 (seen from side) than at base, two upcurved hooks below it (as in allied species) ; 

 the valves on venter have an even inner edge, not excavate toward tip as in B. 

 oblila. Length 14 mm. 



Specimens from Claremont, California "(Baker) ; others from 

 Prescott, Arizona (Oslar); and Pecos, New Mexico, June 21st 

 (Cockerell). Separated from all others by shape of upper piece of 

 male genitalia ; also from R. ohlita in shape of valves, and narrow- 

 head ; from R. ad.nixa in dark basal joint of antennae ; and from 

 R. bieolor in venation and shape of pterostigma.
