 basally whitish transparent, the femora distally shghtly fuscous; tibise and tarsi 

 mostly pale straw; claws slender, evenly cm'ved, longer than the pulvilH, the anterior 

 unidentate. Genitaha; basal clasp segment long, slender, basally with a large 

 internal, cmwed, sub triangular setose lobe; terminal clasp segment moderately stout 

 and rather short; dorsal plate short, deeply and triangularly emarginate, the lobes 

 obHquely roimded; ventral plate broad, broadly rounded apicaUy; style long, tapering 

 to a narrowly rounded apex. 



Female. — Length, .8 mm. Antennae three-fomths the length of the body, sparsely 

 haired, fuscous yellowish; 14 segments, the fifth with a stem one-fom'th the length 

 of the cyhndric basal enlargement, which latter has a length two and one-haH times 

 its diameter; terminal segment somewhat produced, shghtly constricted near the 

 basal thhd, narrowly rounded apicaUy. Palpi; the fu'st segment ii'regularly quad- 

 rate, the second with a length more than twice its diameter, the third one-half longer 

 than the second, shghtly constricted near the basal thhd. Mesonotum brownish 

 yellow. Scutellum yellowish, postscuteUum brownish yeUow. Halteres mostly 

 yellowish or yeUowish orange. Coxse and femora mostly yellowish transparent; 

 tibiae pale straw; anterior and mid tarsi dark fuscous yeUowish, the posterior tarsi 

 pale yellowish. Ovipositor short, the terminal lobes roundl}' triangular and rather 

 thickly clothed with coarse setae. Other characters practically as in the male. 

 Type Cecid. a2643. 



Mycodiplosis fungiperda n. sp. — The pale yellowish, black-eyed 

 midges described below were reared by Theodore Pergande September 

 24, 1896, from orange-colored or whitish larvae occurring in a large, 

 yellowish fungus growing on rotten bark. This species is described 

 through the courtesy of Dr. Howard of the Bureau of Entomology. 

 jMr. Pergande states that the fungus was infested by millions of the 

 larvae, which jumped about like flies, even to a distance of five or six 

 inches and displayed an evident preference for the light. 



Male. — Length, 1.2 mm. Antennae nearly twice the length of the body, thickly 

 haired, pale yellowish; 14 segments, the fifth with stems twice the length of their 

 diameters. Palpi; first segment short, subquadi'ate, the second with a length thi'ee 

 and one-half times its diameter, slender, the thnd a little longer and more slender, the 

 fourth as long as the third; entire body pale yellowish. Wings whitish transparent. 

 Halteres yellowish, shghtly reddish apicaUy. Legs pale straw; claws long, slender, 

 evenly cur^^ed. Genitaha; basal clasp segment long, moderately stout; terminal 

 clasp segment long, tapering; dorsal plate short, deeply and triangularly emarginate, 

 the lobes triangular; ventral plate short, broad, tapering, broadly emarginate; style 

 short, narrowly roimded. 



Female. — Length, 1.2 mm. Antennae nearlj' as long as the body, sparsely haired, 

 pale yeUowish ; 14 segments, the fifth with a stem about three-fourths the length of the 

 subcylindric basal enlargement, which latter has a length about twice its diameter, 

 penultimate segment produced, the basal enlargement with a length thrice its diameter, 

 apicaUy a rudimentary segment; ovipositor short, the lobes narrowly oval. Other 

 characters practicaUy as in the male. Type Cecid. 1315. 



Paralellodiplosis corticis n. sp. — This pale yellowish form was reared 

 by C. V. Riley from larvae occurring in oak bark.
