Dolichopodidae. 213 



Antennæ black, third joint of moderate size, broader than long. 

 Thorax green or bluish green, sometimes a little golden, slightly 

 pruinose, shining. Pleura greenish, greyish pruinose; propleura with 

 a pair of pale or darker bristles. Abdomen green or a little golden 

 green; it is clothed with short, black hairs, and has short hindmarginal 

 bristles, a little longer on the first segment, and somewhat strong on 

 the sixth; the eighth segment with a couple of short bristles. Venter 

 greenish, with yellowish hairs. Legs with the coxæ grey, the trochanters 

 yellow; femora, except the very base and the apex, blackish, shining 

 metaliic green, hind femora almost quite dark, only the apex reddish; 

 anterior tibiæ yellow, hind tibiæ black or brownish, often yellowish 

 above; anterior tarsi with the apex of metatarsus and the four fol- 

 lowing joints blackish. hind tarsi quite blackish, or the very base of 

 metatarsus pale. The legs have short, black hairs, the femora longish 

 hairs below, the front femora on the posterior side, the posterior 

 femora on the anterior side, they are longest and stronger towards 

 the apex; on the middle femora they are present on both sides at 

 the apex; front tibiæ with two small bristles above, or the lower 

 indistinct or wanting; middle tibiæ with two strong antero-dorsal, 

 and with small postero-dorsal bristles; hind tibiæ with dorsal bristles 

 in two rows, and a long ciliation on the anterior side, continued 

 somewhat out on the tarsi ; also the ventral side is somewhat ciliated, 

 especially towards the apex. Wings very slightly greyish tinged; 

 veins blackish. Squamulæ pale yellow, with a yellow fringe. Halteres

 tibiæ yellow with the apical part brown, metatarsus sometimes more 

 yellow than in the male. Abdomen sometimes a little coppery. 



Length 2 — 2,7 mm. 



This species shows in the female a very great resemblance to the 

 female of neglectus, especially to those with the darkest legs, but it 

 may generally be known by the dark apex of the hind tibiæ; also 

 the third antennal joint is disiinctly larger. Kowarz lays (1. c.) special 

 stress on the size in the distinction of these females, but as my 

 measurements show I have found this character of little value. — 

 As Zetterstedt says: „Stæg. in litt." the name is originally due to 

 Stæger. 



C. femoratus is not common in Denmark; Amager, Rørvig, Tis- 

 vilde ; on Funen at Odense; in Jutland at Hald and Mønsted near Viborg, 

 Gjerlev near Randers Fjord, Sæby and Frederikshavn, and on Born- 

 holm at Almindingen and Allinge. My dates are 7^ — "Z^- It occurs 

 often in grass, and may be found on rather dry localities.
