Dolichopodidae. 133 



bristles, some anterior, but only with very small ventral bristles. The 

 bristles on the legs are somewhat long. Wings a little brownish tinged ; 

 veins black or blackish brown, costa with a not large but elongated 

 swelling; discai vein with a moderate or somewhat large, obtuse bend, 

 the lower angle of which is distinctly angular; axillary lobe somewhat 

 small, anal vein going forwards. Squamulæ whitish, with a black 

 fringe. Halteres whitish yellow. 



Female. Epistoma broader than in the male, but not specially 

 broad, yellow or greyish yellow. Antennæ shorter than in the male, 

 third joint short, not longer than broad. Front tibiæ with no long 

 hair at the tip. Wings without costal swelling. 



Length 3,5—4,2 mm, 



This species bears resemblance to acuticornis, but in the male it 

 is at once distinguished by the shorter and differently shaped antennæ, 

 the hypopygium and the long hair at the tip of the front tibiæ; the 

 female may be known by the shape of the antennæ and the grey hind 

 coxæ; also the posterior bristle on the front tibiæ seems to be characteri- 

 stic in both sexes, and likewise the yellow or yellowish epistoma. — The 

 species was originally founded by Stæger on Danish specimens (under 

 the name notatus). 



D. notahilis is somewhat rare in Denmark; Lersøen, Amager, 

 Vester Fælled, Dyrehaven, Ørholm, Faxe Ladeplads; on Funen at 

 Odense; in Jutland at Søndervig, Sminge near Silkeborg and Hulsig 

 north of Frederikshavn; linally on Bornholm at Allinge, My dates 

 are ^le — '^ls. It occurs in fens and on humid piaces, both inland and 

 near the coast; I have once taken it on Iris at a small pond, 



Geographical distribution: — Northern and middle Europe down 

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



Remarks: Kowarz suggests (Wien, Ent. Zeitg, III, 1884, 57) that 

 notabilis and pundicornis are identical; in the Kat, palåarkt, Dipt. 

 they are on the other hånd kept separate; as I, trough the kindness 

 of Dr, S, Bengtsson in Lund, have been able to study Zetterstedt's 

 type of pundicornis, and as I likewise have examined Stæger's speci- 

 mens of notabilis (his notatus), which Zetterstedt had seen, I can 

 prove the identity with certainty. It is curious that Zetterstedt does 

 not compare these two species, but I think that when he once had 

 placed notabilis in the section with black antennæ, and pundicornis 

 in the section with partly yellow antennæ, this has prevented him 

 from comparing them,
