150 Tachinidae. 



protruding. Jowls one half of the height of the eye. In male parallel 

 ocellar and inner vertical bristles present, in female the ocellars 

 divergent and further outer vertical and two orbital bristles present. 

 Postocellar and occipital bristles relatively large. Occiput pale- 

 haired with black hairs behind the postocular bristles. Frontal bristles 

 reaching to insertion of antennæ, in male being small upwards and 

 stopping long before vertex, in female stronger with the uppermost 

 directed outwards. Cheeks hairy in iipper half. Vibrissal ridges some- 

 what converging just below; short vibrissæ ascending above the 

 middle. Eyes with the facets slightly enlarged on inner front part 

 in male. Epistoma not retreating, somewhat reflected in lower part, 

 with a not strong middle carina. Oral cone and proboscis of medium 

 length; clypeus elongated horse-shoe-shaped. Palpi slightly dilated 

 at apex. Antennæ inserted slightly below the middle of the eye, 

 third joint about four times as long as second; arista long-plumose 

 to near end. Thorax nearly quadratic; three postsutural dorsocentrals 

 and two præ- and three postsutural acrostichals. A præsutural intra- 

 alar bristle. Scutellum with four or five marginal bristles on each 

 side. Three sternopleural bristles in position 2 — 1. Pteropleura hairy 

 with a dense bunch above. Propleura hairy. Abdomen ovate; excava- 

 tion on second segment reaching the margin. Fourth segment with 

 a row of marginal bristles, fifth with finer bristles. Fifth sternite 

 excised about to base. Genitaha rather small; upper forceps cleft 

 to middle, arms of lower forceps as long as upper. Legs with not 

 strong bristles ; claws and pulvilH strong in both sexes, a little elong- 

 ated in male. Wings with first posterior cell open, ending a little 

 before apex of wing; discai angle rectangular but a little rounded; 

 apical cross-vein strongly concave; cubital vein with bristles only 

 at base. No costal spine. Lower squamula with long hairs on upper 

 surface. 



The species are oviparous. The larvæ live in carrion and upon 

 the whole in all kinds of decaying animal matter. 



Of the genus 2 European species are well known, also occurring 

 in Denmark; further a couple of other European species are recorded 

 of which one, uralensis Villen. 1922, is recorded to occur in Norway. 

 Perhaps sdso germanonnn Villen. 1904 {Onesia) is correctly placed here, 

 as done by Stein.
