crossvein nearly midway between the wing-margin and the small crossvein ; third 

 vein terminates midway between the second and the wing-tip. Antennae nearly as 

 long as the face, the third joint nearly three times as long as the second ; arista bare 

 the penultimate joint slightly longer than broad ; anterior ocellar bristles directed 

 forward, frontal bristles in a single row descending to the lower end of the eyes; sides 

 of face otherwise bare, each at narrowest point hardly one-sixth as wide as the me- 

 ■dian depression ; face strongly retreating below, in profile concave, ridges strongly 

 diverging below, vibrissa; inserted on the oral margin, widely separated, only one or 

 two bristles above each ; eyes bare ; cheeks nearly half as broad as the eye-height ; 

 proboscis fleshy, the portion beyond the basal articulation scarcely half as long as 

 height of head, labella large ; palpi rather small, clavate. Abdomen long-ovate, of 

 four segments. Hind tibiae not ciliate. Type, the following species : 



Metach£eta atra, sp. nov. 



9 — Black, the palpi and tip of proboscis yellow. Front at vertex one and 

 one-half times as wide as either eye, three frontal bristles in each row curving back- 

 ward, two pairs of orbital bristles; arista thickened on slightly more than the basal 

 half. Body wholly shining, not pollinose ; three postsutural and two sternoplural 

 macrochsetre, scutellum bearing three rather long marginal pairs and two short discal 

 pairs ; second and third abdominal segments each with a discal and a marginal pair 

 of macrochffitce, the fourth with a discal pair and scattered ones on the apical third. 

 Wings blackish along the costa and crossveins, elsewhere gray; first vein bristly on 

 nearly its entire length, the third bristly to slightly beyond the small crossvein ; 

 calypteres white. Front tarsi considerably dilated, claws and pulvilli less than half 

 as long as the last tarsal joint. Length 4 to 5 mm. 



Franconia, N. H. (Mrs. A. T. Slosson); and Northern Illinois 

 (Dr. W. A. Nason). Seven specimens. 



Phyto setosa, sp. nov. 



9 — Black, including the palpi, face largely reddish brown. Front at vertex as 

 vide as either eye, only one frontal bristle in each row curving backward, two pairs 

 of orbital bristles, frontals descending to base of second antennal joint ; antenna; less 

 than half as long as the face, the second and third joints subequal in length, arista 

 thickened on its basal fourth; sides of face bearing a row of macrochsetce, each side at 

 narrowest part over one-third as wide as the median depression, the latter distinctly 

 carinate ; vibrissce inserted the length of the second antennal joint above the oral 

 margin, ridges bare; cheeks nearly as broad as the eye-height; proboscis short, 

 fleshy, palpi clavate. Thorax grayish pollinose, marked with four black vittK ; three 

 postsutural and three sternoplural macrochaetae, scutellum beai'ing three long marginal 

 pairs. Abdomen grayish pollinose ; first segment with a marginal pair of macro- 

 chsetse, second with a discal and a marginal pair, third and fourth each with a discal 

 pair and a marginal row. Wings subhyaline, third vein bristly nearly halfway to 

 the small crossvein, the others bare ; costal spine longer than the small crossvein, 

 apical cell closed in the margin at two-thirds the distance from the second vein to the 

 wing-tip ; calypteres white. Length 6 mm. 



Northern Illinois (Dr. W. A. Nason). A single specimen.
