Empididae. 183 



the lower branch of the cubital vein directed a little downwards, 

 slightly recurved at the apex, the upper branch origmating with an 

 acute angle and diverging, very shghtly curved at the base; the discai 

 cell long, and attenuated towards the apex, the branches of the 

 discai vein issiiing near to each other. Stigma blackish, but faint. 

 Halteres black. 



Female. Qiiite similar to the male; hind tibiæ simple. 



Length 2 mm. 



H. nmmta has only been taken in one specimen, a female, on 

 ^"/e 1909 at Lohals on Langeland (the author). 



Geographical distribution; — Northern and middle Europe down 

 into Austria; towards the north to southern Sweden. 



Remarks: I have examined Zetterstedt's type-specimens, so that 

 my determination is certain. Zetterstedt says, that the front tibiæ 

 in the male are thickened, but in his type this is the case only to a 

 very slight degree (if the specimen is really a male, the apex of 

 abdomen is wanting). It also seems to me, that Strobl's species is 

 the same. — In the Kat. palåarkt. Dipt. the species is enumerated 

 under Bhagas, it seems on the authority of Loew (Nat. Hist. Rew. 

 1856, 86); I do not know Loev^-'s paper, but I see no reason for 

 separating the species from Hilara. 



As mentioned under the description of the family, still one species 

 is recorded from Denmark viz. H. fuscipes Fabr. According to Fabricius 

 (Ent. Syst. IV, 406, 14 and Syst. Antl. 144, 5) this species is founded 

 on Danish specimens, as he says: „Habitat in Dania Mus. Dom. Lund." 

 As said above under the family the specimens in Lund's collection 

 labelled Tachydromia fuscipes are not this species, and as I think 

 there is no fuU certainty for the occurrence of the species in Den- 

 mark, I have at present omitted it. 



3. Ocydromiinae. 



Eyes either touching in the male, separated in the female, or 

 touching in both sexes; in rare cases narrowly separated in both 

 sexes; when touching the upper facets are in the male generally 

 larger than the lov^er. Antennæ either five-jointed, with a two- 

 jointed style or long arista, or three-jointed, with a long, not articu- 

 lated arista. Proboscis short, sometimes somewhat long and then 

 directed straightly or obliquely forwards. Maxillæ (always?) present, 

 the inaxillary palpi one-jointed. Thorax somewhat high and arched.
