Pale yellowish, head and thorax unmarked, clothed with' yellow hair; abdomen 

 brown toward tip ; legs with black spines and yellow spurs, latter 1-2-2 ; antennce 

 yellow ; wings yellow, clothed with yellow or tawny hairs, with five dark brown, 

 pointed stripes ; one on the discal cell, one in fourth apical reaching nearly to tip, 

 one in second subapical, one in the thyridial cell, and a long one near base in anal 

 area. Hind wings yellowish ; venation of both pairs yellowish. The posterior and 

 anterior anastomoses are in the same line, making the apical cells very long. The 

 wings are rather more slender than in // flavipeiinis and the spur formula different. 

 Length to tip of wings 20 mm. 



One specimen from Ormsby County, Nev., July 6 (Baker). 



Asynarchus pallidus, sp. nov. 



Face yellowish, vertex brownish-yellow ; antenna brown, pale yellow toward 

 tips. Head and thorax with yellow hair ; ocelli of moderate size. Meso- and 

 metathorax yellowish ; abdomen pale brown ; legs pale yellow, with black spines 

 wings pale yellow, sparsely yellow-haired, with yellowish venation, except that the 

 anastomosis is usually dark ; a dark dot usually present in base of third apical cell in 

 both wings, fifth apical cell in fore wings acute or even pedicellate, in hind wings first, 

 third and fifth apicals are acute at base ; anastomosis in hind wings often weak or 

 lacking ; radius in fore wings bent at pterostigma ; discal cell as long as pedicel. 

 Length to tip of wings 15 mm. 



South Park, Colorado, August 23 (Oslar). This species apparently 

 approaches the genus Parachiona Thomson. 

 Neophylax fuscus, sp. nov. 



Head black, with black hair ; antennae yellowish, basal joints long, brown ; thorax 

 black, with mostly black hair ; abdomen brown, legs pale yellowish, with a few black 

 spines. Spurs 1-2-2. Wings dark brown, indistinctly irrorate with pale ; hind 

 wings dusky ; venation of both pairs brown. Shape of wings and venation much a. 

 in N. concitinus ; the pterostigma prominent, and radius strongly bent at this point. 

 In hind wings the apical cells are variable, as in A^. conciniius. Length to tip of 

 wings 9 mm. 



Agricultural College, Michigan, September 25 (Pettit) ; and Fran- 

 conia, N. Hamp. (Mrs. Slosson). 



Leptocerus floridanus, sp. nov. 



Head yellowish, clothed with long, white hair ; pronotum with long white hair ; 

 rest of thorax yellowish, with shorter and more sparse white hair ; antennae white, 

 narrowly annulate with dark brown ; legs yellow, with short white hair, tarsi banded 

 on tips with brown ; w^ngs pale brown, rather densely clothed with white hair, 

 mostly in small patches, giving the wing a marmorate appearance ; apical fringe alter- 

 nately brown and white ; hind wings with the apical part slightly infuscateds 

 Length to tip of wings 10 mm. 



One specimen from Biscayne Bay, Florida (Slosson). 



Differs from all our other species in the covering of hoary hair.
