reduced, about as long as the first. Mesonotum yellowish brown, 

 the submedian lines sparsely haired. Scutellum yellowish transpar- 

 ent, postscutellum a little darker. Abdomen reddish brown, the 

 genitalia yellowish red. Wings subhy aline, being rather thickly 

 clothed with short, curved scales, the third vein uniting with the 

 margin at the apex of the wing. Halteres reddish brown. Coxae 

 brownish yellow. Legs mostly thickly clothed with fuscous scales, 

 the distal tarsal segments on the anterior legs somewhat lighter. 

 Claws heavy, strongly curved, simple, the pulvilli rudimentary. 

 Ovipositor when extended nearly as long as the body, the dorsal 

 lobes divided, subquadrate, and only sparsely haired, the basal por- 

 tion of the ovipositor fleshy, eversible, the distal part aciculate as in 

 AspJiondylia. Type Cecid. 1534. 

 Type.— Cat. No. 18489, U.S.N.M. 



ASPHONDYLIA ALTANI, new species. 



The midge is labeled San Marcos, Nicaragua, Baker collection. It 

 is an interesting form in that it presents a comparatively generalized 

 condition of the antennae, the basal, flagellate segments not being so 

 greatly prolonged as in many of the typical species referable to this 

 genus. 



Female. — Length, 3 mm. Antennae nearly as long as the body, 

 sparsely haired, dark brown; 10 and probably 14 segments, the fifth 

 cylindric, with a length about four times its diameter, the basal cir- 

 cumfilum broadly sinuous and united with the nearly transverse 

 apical filum by two longitudinal fili; terminal segments wanting. 

 Palpi; first and second segments short, the second narrowly oval, 

 with a length over twice its diameter, the third more than twice as 

 long as the second, slender, basally capitate. Mesonotum grayish 

 brown. Scutellum reddish brown, postscutellum yellowish brown. 

 Abdomen a dark reddish brown. Wings hyaline, the third vein 

 uniting with the margin at the apex of the wing. Halteres yellowish 

 basally, whitish apically. Coxae and legs a nearly uniform yellowish 

 brown, the pulvilli nearly as long as the relatively slender, strongly 

 curved claws. Ovipositor when extended nearly as long as the body. 

 Type Cecid. 1533. 



Type.— Cut. No. 18490, U.S.N.M. 



EOCINCTICORNIA, new genus. 



Antennal segments 14, cylindric, sessile, the distal ones not plainly 

 reduced and bearing in both sexes, low, finely reticulate circumfHi. 

 Palpi triarticulate. Wings with the third vein heavy, uniting with 

 the margin just beyond the apex of the wing, the fifth vein, obsoles- 

 cent distally, the anterior branch practically obsolete. Male geni- 

 talia with the basal clasp segment greatly produced, the terminal
