Dolichopus brevipennis Meigen. 



Four males, Skaane, Sweden, (Henry G. Klages). I have not 

 seen it from North America. 



Dolichopus albicoxa, n. sp. 



Male. Cilia of inferior orbit and of tegulae pale, antennae black, 

 first joint largely red below, hind tibiae black at tip. 



Face of moderate width, white; front shining green; third joint of 

 antennae rather large. Thorax green, very shining; pleurae green, 

 white-dusted. Abdomen green, toward the tip coppery. Lamellae 

 of hypopygium white on the basal half, the rest with a brownish 

 tinge, from the black hairs inside, which show through; border black- 

 ish, with the bristles confined to the apex. Legs yellow, fore coxae 

 with considerable white pollen, and some microscopic white hairs, 

 but no black hairs or bristles except about six at the end; in certain 

 directions these coxae appear almost white; middle and hind coxae 

 black, broadly yellow at tip. Hind femora not ciliated. Last fourth 

 or fifth of hind tibiae black, as also the whole hind tarsi. Fore tarsi 

 one and one-half times as long as the tibiae; first three joints slender, 

 stalk-like; fourth very short, black, compressed; last joint longer, 

 oval, also compressed and black, the claws attached before the ex- 

 tremity. Wings slightly yellow, costa scarcely thickened. 



Length, 5 mm.; of wing, 4 mm. 



Two males, Massachusetts and Connecticut (U. K. ). The female 

 will probably be distinguished from that of brevhnanus and socius by 

 having fore tarsi longer than the tibiae. 



Dolichopus longimanus Loew. 



Three females, two from Hanover, N. H. (Weed), one from Custer, 

 S. D., are readily distinguished by the dark color of the basal half of 

 the fore coxae. 



Dolichopus brevimanus Loew. 



Two female specimens, Massachusetts and Connecticut (U. K.), 

 may belong to this species; but the differences among the females of 

 this and several other species of the group are so slight that no posi- 

 tive conclusion can be arrived at without a larger amount of material. 



Dolichopus socius Loew, 



One male, Massachusetts (U. K. ), is 3.5 mm. long, but otherwise 

 agrees well with the description. 



Dolichopus palsestricus Loew. 



One male, Dover, N. J., June 18 (C. W. Johnson).
