Pipiza. 93 



all whitish, Genitalia black-haired. Venter translucent at the base, 

 black towards the end, with long hairs, pale at base, black at the 

 end. Legs black, knees only indistinctly reddish, tarsi black, the two 

 basal joints paler to brownish or in the highest dark yellowish. Hind 

 femora strongiy clavate, the greatest thickness lying quite near the 

 end and from here sloping abruptly below to the apex; hind tibiæ 

 rather stout and on account of the shape of the femora more curved 

 at the base than usual ; hind metatarsi somewhat thickened. Legs 

 haired as usual, the hairs all white, only dark just at the apex of 

 front and hind femora. Wings clear on the basal part, stigma brown, 

 below it a strong, brown blotch dying evenly away outwards so that 

 the apical part of tlie wing is slightly brownish. Squamulæ whitish, 

 the margin a little darker. Halteres yellowish. 



Female. Antennæ with the third joint larger than in the male 

 but Mkewise not at all longer than broad. Frons somewhat punctate, 

 side dust spots large, especially long, almost connected along the eye- 

 margin with the pruinosity on epistoma. Frons black-haired in front 

 of the ocelli and above the antennæ, pale haired in the middle. Eyes 

 shorter and much paler haired than in the male, Thorax and abdomen 

 haired as in the male, the hairs on thorax short. 



Length 8 to fully 9 mm. 



This is a somewhat strong and stout species, and certainly a good 

 species. It is distinguished from lugubris by the shorter antennæ with 

 the third joint not longer than broad, and by the moi-e strongiy 

 clavate hind femora; the abdomen is more conspicuously white-haired, 

 and the white hairs form more conspicuous bands. The wing blotch 

 seems still stronger and larger, and it is not in the female sharply 

 defmed outwards as in lugubris. — I have named the species austriaca 

 Meig. for the foUowing reasons: As declared the foregoing species is 

 lugubris F. determined after the type. If we now suppose that 

 Meigen had seen Fahricius's type (which is probable according to the 

 introduction to his work) and determined his species correctly, and if 

 funebris is only a synonym to lugubris, then I fmd no other descrip- 

 tion which answers to the present species, than that of austriaca. In 

 reality the description of funebris and lugubris with "Hinterschenkel 

 stark'verdickt" would seem to answer better to the present species 

 than that of austriaca with ''Hinterschenkel etwas verdickt," but 

 according to the above this interpretation is not well possible. 

 There are thus here two distinct species, and I think that Kowarz's 

 suggestion (1. c.) that Schiner's austriaca is identical with lugubris F. 

 and vice versa is somewhat probable, and for the same reason I do 

 not think that austriaca is synonym to festiva as given with a querry
