acute and rather long, third vein with very short bristles from base

Length, 2^ mm. 



One specimen, White Mountains, New Hampshire (Morrison), 

 from collection of C. V. Riley. 



Type.— Cut. No. 14823, U.S.N.M. 



Near to vitrea Wood and suhlugubris Wood, especially the latter, 

 but quite easily separable. Labelled Phoraaptina, Schiner (Coquillett). 



TRUPHEONEURA FRATERCULA Brues. 



Male. — Black; frons short, one and three-fourth times as broad 

 as long, with the usual bristles, antennae black, of rather large size 

 and strongly pubescent, arista pubescent and much thickened at 

 base, palpi small, black, bristling normal; thorax subshining, two 

 scutellar bristles; abdomen dull black, grayish pollinose, hypopygium 

 of rounded form, black and slightly pollinose; legs long and rather 

 slender, a little lighter on the anterior coxae and knees, mid and fore 

 tibial bristles as usual, hind tibial bristle at the basal third; wings 

 slightly infuscated, costa to wing middle, first division equal to the 

 other two together, fringe very short and close, fourth vein leaving j

Described from two males from Jackson's Lake, Wyoming.^ The \ 

 type specimen in the collection is in very poor condition as it has lost 

 both wings. There are two specimens from Plummers Island, 

 Maryland, ''from wasp's nest," that may be females of this species, 

 but they are in rather poor condition. They are certainly not 

 microcepTiala Loew, as labeled.

 boscis brown, smaller than palpi; thorax shining, scutellum with two 

 strong bristles; abdomen broad, dull black in color, first and second
