Dolichopodidae. 217 



Female. Epistoma broader than in the male. Third antennal 

 joint a little smaller. Thorax green or æneous green; abdomen more 

 bluish green. Anlerior tibiæ yellowish or brownish, hind tibiæ brown, 

 all darkest towards the apex; the antero-dorsal bristle near the base 

 on the middle tibiæ distinct. 



Length 2—2,5 mm. 



This beautiful species is easily recognised in the male by the 

 broad epistoma, the slightly haired legs and the colour, and in both 

 sexes by the white-haired front coxæ and the small acrostichal hairs. 



C. laesus is not at all common in Denmark; Bagsværd, Hillerød, 

 Tisvilde; on Langeland at Lohals ; on Funen at Veflinge; in Jutland 

 at Ry near Silkeborg, Gjerlev near Randers Fjord and Sæby, and on 

 Bornholm at Almindingen and Hasle. My dates are only ^'^le—^^h. 

 It occurs on bushes and in grass and low herbage on meadows in 

 woods and on similar piaces. 



Geographical distribution : — Northern and middle Europe down 

 into France; towards the north to middle Sweden, and in Finland. 

 Strobl mentions (Mittheil. Ver. Steierm. 1892, 143.) that he has taken 

 it commonly at a height of 4000 feet. 



Remarks: — We have in our coUection the type specimen to 

 Zetterstedt's C. ampUcornis; the author compares it with C. laesus and 

 says: "an vere distinctus '? ?" ; this is also correct, for the species is 

 laesus, and not, as Zetterstedt describes, a female, but a male. Kowarz' 

 ampUcornis must thus have a new name, I propose C. Kowarzi.
