light brown, the stout third vein uniting with tlie margin just beyond the apex, 

 the fifth vein forked. Halteres yellowish transparent. Legs mostly a yellowish 

 straw, the tarsi somewhat darker ; claws slender, strongly curved, with a long 

 tooth basally ; pulvilli small, about one third the length of the claws. Genitalia : 

 basal clasp segment slender, strongly curved, obtusely lobed basally ; terminal 

 clasp segment rather stout, tapering ; dorsal plate broad, broadly and roundly 

 emarginate ; ventral plate rather long, broad, broadly emarginate. both sparsely 

 setose : style long, slender, tapering. 



Female. — Length, i mm. Antenn;e nearly as long as the body, sparsely 

 haired, dark brown : 14 segments, the fifth with a stem one third the length 

 of the cylindric basal enlargement, which latter has a length about twice its 

 diameter and sparse subbasal and subapical whorls of set;e : terminal segment 

 slightly reduced, with a short, obtuse process apically ; pulvilli nearly as long 

 as the strongly toothed claws. Ovipositor stout, with a length about one half 

 that of the abdomen, the terminal lobes broadly ovate and thickly setose. 

 Other characters nearly as in the male. 



Exuvice. — Length. 0.5 mm., stout, whitish ; thoracic horns long, stout, taper- 

 ing ; antennal cases e.xtending to the second abdominal segment, the wing cases 

 to the fourth abdominal segment and the leg cases almost to the ape.x of the 

 body : skin apparently smooth. 



Larva.- — Length, 3 mm., whitish, stout, the extremities rounded ; breast- 

 bone bidentate, the teeth large, triangular, the shaft transparent. 



Reared by W. H. Pattersons, St. Vincent, W. L, from presumably blister 

 galls on very young leaves of Mangifera indica. 



Type Cecid 3.2117. N. Y. State Museum. 



Allied to Loboptcromyia Felt by the broad wings with the some- 

 what produced anal angle and the short basal portion of the stem in 

 the flagellate antennal segments of the male. Easily recognized by 

 the distinctly toothed claws, a character rarely appearing in the 

 group bifili. South America. 



Genus THURAUIA Riibs. 1899, type T. aqualica Riibs. 

 Easily distinguished from the preceding by the long antennal stems, 

 the basal one of the fifth antennal segment with a length three times 

 its diameter. The wings are greatly produced, narrow, with a length 

 at least three times the width. The female has the distal portion of 

 the ovipositor greatly produced and chitinized. Europe. 



Genus ENDAPHIS Kieff. 1896, type E. perfidus Kiefif, 

 Allied to Contar'uiia. though easily separated therefrom by the 

 narrow scales on the wing membrane and the tooth-like dorsal pro- 

 longation of the first antennal segment. Ovipositor of the female 

 short, the lobes long, slender. Europe, North America. South .America.
