This genus was erected by Meinert in 1865 with O . para- 

 doxus as the type and sole species. Members of this genus may 

 be recognized by the finely haired wing membrane and the 2 or 3 

 simple veins in connection with the biarticulate tarsi, the first seg- 

 ment being shorter than the second. The mouth parts are rudi- 

 mentary or wanting.

This species was taken on a window at Albany, N. Y., July 15, 

 1907 and was presumably reared from material brought into the 

 office. 



Female. Length 1 mm. Antennae extending to the second ab- 

 dominal segment, pale yellowish; 13 segments, the fifth and follow-

 the diameter ; terminal segment reduced, narrowly rounded apically 

 and irregularly clothed with long, chitinous spines. Palpi apparently 

 wanting, eyes small, brown, ocelli absent; face yellowish. Meson- 

 otum light brown, pleurae pale orange. Scutellum and postscutel- 

 lum light fuscous yellowish. Abdomen pale yellowish, the basal 

 and distal segments pale orange, the ovipositor pale white. Wings 

 long, narrow, hyaline, costa pale yellowish, subcosta uniting w r ith

 half, the fifth indistinct distally, joining the posterior margin at 

 the basal half, its branch at the basal fourth, entire margin thickly 

 clothed with long, rather stout hairs. Halteres yellowish trans- 

 parent. Legs pale yellowish white. Coxae short, irregular ; femora 

 long, stout, fusiform, tibiae a little longer, with weak spines apically,
