Polychaetoneura elyii n. sp. 



Length 3 to 4 mm. Female, yellow, thorax gray pollinosc. Front 

 slightly wider than eye, yellow, parafrontals yellow, whitish pollinose. 

 Frontal vitta yellow, opaque, nearly twice as wide as either paraf rental. 

 Face yellowish -white fading into white on cheeks and epistoma, facial 

 depression very broad, sides of face narrow not more than one-eighth as 

 wide as depression. Vibrissa; black situated slightly below front edge of 

 oral margin. Palpi and proboscis whitish. Antenna; large, reaching 

 almost to oral margin, first, second and base of third joints pure yellow, 

 apical two-thirds of latter darker verging on brown. Arista incrassated 

 on basal third which part is yellow, remainder black. Arista pubescent, 

 almost to, but not reaching tip, hairs nearly as long as greatest diameter 

 of style. Cheeks whitish bearing a few short bristles on front portion of 

 disc and two or three forwardly curving macrochaeta; on their lower margins. 



Two pairs of orbitals, frontals descending to lower edge of first antennal 

 joint. Entire occiput whitish thinly clothed with whitish bristles and 

 hairs. Thorax including scutellum, entirely opaque gray pollinose, only 

 the merest suggestion of vitta; on the anterior portion when viewed from 

 behind. Post sutural bristles four, sterno pleurals two with sometimes a 

 large bristle-like hair or two below them towards the middle of sterno 

 pleural plate. Abdomen ovate yellow, slightly darker toward apex. First 

 segment destitute of true macrochsetse, second, third and fourth, bearing

 venter yellow. Legs including coxae yellow, middle tibia? on front side 

 slightly beyond middle with a single strong macrochseta. Hind tibia not

Described from three females reared from Schizura concinna 

 at East River, Connecticut, August 2, 1912, by Mr. C. R. Ely, 

 in honor of whom the species is named. This insect is remarkable 

 chiefly because of its having the fifth vein of the wings bearing 

 setulae, a character unique among the Tachinids of this country 

 so far as I am aware.

Female: Rather slender, black and orange yellow. Wings slightly infus- 

 cated along costal margin. Length 5 to 7 mm. Female, frontal vitta opaque 

 velvety black, bordered on each side with bands of shining black which

 of antenna;, area outside of these also lower half of front and fascialia sil- 

 very pollinose. Antennae opaque black, about two-thirds length of fare,
