108 NATHAN BANKS. 



Anaboliiia diversa Banks. 



Specimens of this species were taken at Las Vegas, May 17th, at 

 light (Cockerell). They are rather larger than the Arizona specimens. 



Psilopleryx (?) brevipeililis u. sp. — Pale yellowish ; abdomen brown- 

 ish above ; venation brown. Clothed on head and thorax with whitish and yel- 

 lowish hairs, longest ou the prothorax above ; wings sparsely hairy along the 

 veins, as well as ou the margins. Head rather broad, slightly depressed in mid- 

 dle of vertex, ocelli small, two transverse posterior warts; face retreating; basal 

 joint of antennae moderately large. Prothorax distinct from above, about four 

 times as broad as long. Legs of moderate size, with many black spines; spurs 

 ( 9 ) 1-3-4, yellowish. Wings ( 9 ) short ; anterior pair not reaching tip, and pos- 

 terior pair scarcely extending beyond middle of abdomen ; the foiiner broad and 

 broadly rounded at tip, the latter much narrower and acute at tip; discal cell 

 triangular, reaching nearly half-way to base, fifth apical cell narrow at base. Ab- 

 domen large, largest toward tip. Length 8 mm. 



One female from Beulah, 8000 feet (Cockerell). It is not a Psi- 

 lopteryx as that genus is now defined. However, by shape of wing, 

 unbent radius near pterostigma, and shape of head, it is allied to 

 Chcetopteryx, differing from it in not having hairs on wing-membrane 

 (just as Psilopteryx) ; however, it differs from both these genera in 

 the spur formula. It may be a Psilopteryx when these genera are 

 based on more natural characters. 



Family RHYACOPHILID^. 



Rhyacopllila Stiginatica n. sp.— Black ; head with sparse black hair; 

 antennae faintly annulate; legs pale yellow, a dark mark on tips of tibiae and on 

 tips of tarsal articles, much more distinct in male, and most distinct on the ante- 

 rior legs, absent in hind legs of female ; spurs yellow. Wings black, more or less 

 guttate with pale yellowish, in male heavily marked, in female with few spots 

 and these chiefly at margins; a larger yellow spot near anal angle; pterostigma 

 darker than eLsewhere, in hind wings very dark and prominent, especially in 

 males; the apiciil part of hind wings in fuscated, veins blackish. Length to tip 

 of wings 11 mm. 



Specimens come from Las Vegas, July 10th, and Beulah, July 

 27th (Cockerell); also from Colorado. The female, which is but 

 little marked, looks like R. pacifica, but the wings, especially the 

 hind pair, are not near so dark. 



Glossosoina parviila n. sp. — Dark brown ; head clothed with white hair ; 

 posterior warts small, transverse; palpi dark; antennae pale yellowish, darker 

 toward tip; thorax with white hair; abdomen dark brown; legs pale yellowish, 

 with brown spurs. Wings rather sparsely clothed with black and golden hairs, 

 the basal half mostly golden ; a whitish spot at end of thyridial cell ; veins and 

 apical fringe dark brown ; venation as usual ; fifth apical cell reaches as far back
