Gaedia. 347 



Remarks: As seen in the above description our species most 

 often has no discai abdominal bristles; this would lead io Proso podes 

 fugax Rond., and probably this is only a synonym, as already sug- 

 gested by Girschner (Entom. Nachr. XXV, 1899, 177) and later on 

 by Schwangart; also Stein is of the same opinion. 



73. Gaedia Meig. 



Species of medium size and of blackish colour, with greyish 

 pruinosity; on sides of abdomen reddish spots. Head as broad as 

 thorax, somewhat convex behind and somewhat puffed out below, 

 much higher than long. Frons broad and a little broader in female 

 than in male, only slightly protruding, somewhat rounded in profile; 

 cheeks rather broad, narrowing downwards; jowls broad, fully half 

 the height of the eye. In both sexes ocellar and inner vertical, in 

 female also outer vertical and two orbital bristles. Relatively large 

 postocellar and distinct occipital bristles. Behind postocular bristles 

 no black hairs. Frontal bristles descending to end of second antennal 

 joint, the uppermost one reclinate. Cheeks with a row of bristly hairs. 

 Vibrissæ ascending to the middle. Epistoma retreating, somewhat 

 reflected below. Eyes bare. Antennæ inserted slightly above middle 

 of the eye, second joint somewhat elongated, third nearly twice as 

 long as second; arista with second joint short. Thorax rectangular, 

 the sides converging behind so that it is narrower behind than in 

 front; three postsutural dorsocentrals, and three præ- and three 

 postsutural acrostichals ; a præsutural intraalar bristle. Scutellum 

 with four marginal bristles on each side, the apical small, diverging; 

 a pair of discai bristles. Three sternopleural bristles. Pteropleura with 

 a bristle above. Abdomen with excavation on second segment reaching 

 hind margin ; it has discai and marginal bristles, second segment with 

 a pair of marginal. Legs with anterodorsal bristles on hind tibiæ 

 unequal; claws and pulvilli elongated in male; front tarsi in female 

 simple. Wings with first posterior cell closed and quite short petiolate, 

 ending somewhat before apex of wing; discai angle sharp, nearly 

 rectangular; a somewhat large costal spine. 



Of the genus two European species are known, (or only one, if 

 distincta Egg. is the same as connexa, as Stein declares); one occurs 

 in Denmark. The development is not known, but the species is recorded 

 to belong to Pantel's group 2.
