L.eptocelIa coloradensis n. sp.— Head yellowish; basal joints of 

 anteiuise same color, other joints narrowly annulate with brown ; thorax rather 

 reddish; abdomen pale at base, darker toward tip: legs pale yellowish; wings 

 hyaline, rather shining, very scantily clothed with short pale hairs, bind pair with 

 rather short pale fringe ; antennse twice as long as wings, basal joints very large, 

 swollen above; spurs 0-2-2, fore wings long and narrow, discal cell slender, but 

 much shorter than its pedicel, longer than apical cells, first apical rather shorter 

 than its pedicel, fourth apical short pedicellate, hind wings much shorter than 

 fore pair, with a broad folded anal space, veins on anterior part indistinct. 

 Expanse 24 mm. 



Colorado (Baker). 



Ketodes americana n. sp. — ralpi with black hair; antennse white be- 

 yond the basal joint, annulate with black ; thorax dark, with white hairs; abdo- 

 men brownish; legs pale yellowish, anterior pair darker, fore wings with black 

 hair and blackish veins, and a black fringe; in well-marked specimens some 

 whitish dots on hind part of wing, a larger one at anal angle; hind wings gray, 

 with long dark gray fringes; antennse very long and slender, two and one-half 

 times as long as wings; fore wings long and slender, acute at tip, no closed discal 

 cell, first apical cell pedicellate, fourth apical cell acute at base, no fifth cell, hind 

 wings rather narrow, and a little shorter than fore pair, acute at tip, three main 

 veins, each forked, the upper branch of first forked again near tip, first and sec- 

 ond connected just before the first fork. Expanse 13 mm. 



Washington, District of Columbia, July. 



«ECETII«A n. gen. 



Differs from the typical Q^cetis by having a much longer discal 

 cell, and in the first apical reaching anastomosis, hind wings are not 

 very broad. 



Type CE. incerta. 



CEee9.ina incerta Walk, {micans Hag.). — Wings not densely clothed with 

 hair, rather subnude. luteous, anastomosis brown, discal cell not extending much 

 beyond thyridial cell, fifth apical cell does not extend along thyridial basad of 

 anastomosis, thyridial cell less than one-third longer than discal cell. Expanse 

 17 mm. 



Long Island, New York, July ; Washington, D. C. 



<Eeetina parviila n. sp.— Head and thorax brown, with gray hair; palpi 

 gray; antennse pale, annulate with black; legs pale yellowish ; abdomen green- 

 ish ; wings with black hair and fringe, anastomosis brown, fore wings slender, 

 acute at tip. discal cell projecting a little beyond thyridial cell, fifth apical not 

 extending on thyridial cell, no distinct mark on base of discal cell, thyridial cell 

 not much longer than discal cell. Expanse 11 mm. 



Washington, District of Columbia. 



Distinguished by its small size and short thyridial cell, smaller 

 and more hairy than CK. incerta,
