Dolichopus scoparius Loew. 



Two males and a female, Dover, N. J.. June 23; Philadelphia, July 

 14 (Johnson); Mass. (U. K.). Wheeler (Psyche, May, 1890, p. 339) 

 has described the very peculiar male lamellae. In my best preserved 

 male the face is decidedly grayish yellow, and not at all white except 

 at the lower border. 



Dolichopus duplicatus, n. sp. 



Male: antennae red, third joint black;, cilia of inferior orbit pale, 

 of tegulae black; legs yellow, hind tarsi yellow at base. 



Face light yellow, rather wide; front green, opaque, with yellow 

 dust. Thorax green, thickly dusted with yellow except in the neigh- 

 borhood of the scutellum; brown stripes above root of wings distinct; 

 pleurae blackish green, moderately dusted. Abdomen green, coppery, 

 the sides a little light-dusted. HypOpygium dusted, opaque, shining 

 black only at tip. Lamellae very large, yellov/, the outer margin ex- 

 cised so as to leave an apical and an upper lobe; the apical margin in 

 my only specimen is somewhat folded in and difficult to examine; it 

 appears, however, not to have any strong bristles nor black border, 

 but only a fringe of short hairs. Fore coxae yellow with black hairs 

 on the front side; middle and hind coxae black, with yellow tips. 

 Femora and tibiae yellow; hind femora not ciliated, hind tibiae plain. 

 Fore tarsi one and one-half times the length of the tibiae, the first 

 two joints slender and stalk-like, yellow; third joint also slender, 

 blackish; fourth joint triangular, black, with a border of long black 

 hairs above; fifth joint twice as long as the fourth, compressed, over 

 half as wide as long, oval, projecting beyond the claws a little, black, 

 with a black fringe above. Middle and hind tarsi gradually infus- 

 cated from the tip of the first joint. 



Wings nearly hyaline, broad, the margin deeply notched at the fifth 

 vein; costa scarcely thickened. 



Length, 6 mm.; of wing, 5.5 mm. 



One male, State of Washington {\J. K. ). 



Dolichopus plumosus, n. sp. 



Male; antennae red, third joint black; cilia of inferior orbit pale, 

 of tegulae black; legs yellow, hind tarsi at base yellow. 



Face uniform jnire yellow; front shining green. Thorax green, 

 moderately shining; pleurae blackish-green, light-dusted. Abdomen 

 bright green; hypopygium small, shining green or bronze at base, black 

 at tip; lamellae pale yellow, elongated, broadly black-margined at 

 apex, where they are also jagged, with curved and branched black bris- 

 tles. Along the upper margin the black border grows narrower, and 

 the bristles are small. Fore coxae yellow, with both yellow and black
