TOXOMYIA n. g. 



The unidentate anterior claws and two circumfili indicate a 

 relationship to Erosomyia Felt from which it is easily separated 

 by alar characters. The dentate anterior claws prevent the 

 reference to this form to Contarinia and the same is true of 

 the genitalia, which latter approach in structure those of The- 

 codiplosis. 



Type. To.i'omyia fwigicola n. sp. 



Toxomyia fungicola n. sp. 



The small, yellowish midge was reared February 3, 1911, 

 from the teleutospores of Puccinia species on Emilia sonchi- 

 folia. 



Male.. Length .75 mm, Antennae twice the length of the body, 

 thickly haired, light brown ; 14 segments, the fifth having the two por- 

 tions of the stem with a length 2^/2 and 3^2 times their respective 

 diameters ; the basal enlargement subglobose. the subbasal whorl thick, 

 the circumfilum with long loops, those on the dorsal surface produced 

 to extend beyond the subglobose distal enlargement, which latter has 

 a scattering subbasal whorl of stout setae and a circumfilum with long 

 loops, likewise somewhat produced on the dorsal surface and extend- 

 ing beyond the base of the following segment ; distal segment produced, 

 the basal portion of the stem with a length fully seven times its 

 diameter, the distal enlargement subglobose and with a slightly taper- 

 ing, finger-like process having a length five times its diameter; mouth- 

 parts somewhat produced. Palpi : first segment short, subquadrate, the 

 second with a length twice the first, rather slender, the third as long 

 as the second, the fourth a little longer than the third ; the entire body 

 a pale yellowish or yellowish red ; the genitalia somewhat fuscous. 

 Wings hyaline, costa light straw, subcosta uniting with the margin at 

 the basal third, the third vein a little beyond the apex; the fifth vein 

 uniting with the posterior margin at the distal fourth, its short branch 

 near the basal third. Halteres yellowish transparent, fuscous apically. 

 Legs mostly pale straw, the distal tarsal segments darker ; claws long, 

 slender, evenly curved, the anterior unidentate. the pulvilli rudimentary. 

 Genitalia : basal clasp segment moderately long, slender, with a distinct, 

 broadly rounded, setose lobe at the internal basal angle ; terminal clasp 

 segment slightly swollen basally, long and evenly curved ; dorsal plate 

 short, roundly and triangularly emarginate, the lobes broad, truncate 

 and sparsely setose ; ventral plate a little longer, rather broad, tri- 

 angularly emarginate, the lobes rather stout, slightly diverging and
