204 Tachinidae. 



decumbent hairs. Fifth sternite \vith a brush and strong but not 

 long, dense marginal bristles. Genitalia large; præhypopygial seg- 

 ment black with a slight, greyish brown pruinose middle spot, and 

 with strong marginal bristles. Hypopygium red, somewhat densely 

 hairy; upper forceps cleft to near middle, the arms ciirved a little 



ventrally, with a small dorsal hump at 

 base and from here slightly hollowed in 

 upwards and with a narrow furrow along 

 dorsal margin ; there is a very slight excision 

 at apex; the forceps only moderately hairy, 

 the arms bare; on the dorsal hump there 

 is a little brush of short hairs. Anterior 

 claspers longer than posterior, straight, 

 with the blunt end rectangularly bent; 

 posterior claspers likewise straight, with the 

 end hook-shaped and pointed. Penis with 

 Fiff 63 S frenata ^ small short and pointed end, bent slightly 



forwards; a large, roundish brown lobe is 

 seen and at the end two pairs of quite small apophyses, the median 

 bent upwards and bristle-like. Middle femora somewhat densely, 

 hind femora more sparingly fringed below; hind tibiæ long-fringed 

 on posteroventral side but sparingly, with the hairs distant, and not 

 or almost not fringed on anteroventral side (the hairiness very 

 varying according to the size); middle femora with a not strong 

 comb; hind femora with an anteroventral row of long bristles. Wings 

 somewhat tinged; costal segment 3 slightly longer than 5; subcostal 

 vein with bristles (or bare); a somewhat small costal spine. 



Female. Frons about as broad as the eye. Sixth abdominal 

 segment more or less red; the split elliptical, not triangular, narrowed 

 both above and below, and above produced somewhat forwards, 

 with strong marginal bristles; the split has, as seen, another shape 

 than in haemorrhoa. 



Length 8 — 9 mm (after Bottcher 7 — 12 mm). 

 The described form belongs, as it has bristles on subcostal vein, 

 to var. cruentata Pand.; the frenata with bare subcostal vein I have 

 not seen. 



S. frenata seems rare in Denmark, I know only 8 specimens, a 

 copulated pair taken in Ermelund (the author), a male from Veflinge 

 on Funen (H. J. Hansen), two males and a copulated pair from 

 Jutland at Skanderborg (the author) and a male from earlier time
