394 Tachinidae. 



G. ornata is much more common in Denmark than capitata; 

 Ordrup Mose, Ermelund, Holte, Hareskov, Hillerød, Grib Skov, 

 Tisvilde, Roskilde; on Lolland at Strandby; in Jutland at Nyminde- 

 gab, Hadsten, Funder and Frederikshavn, and on Bornholm at 

 Arnager; the dates are ^1^ — ^^Z,, it is thus an early species. It occurs 

 frequently in sandy localities. It is parasitic on Agrotis vestigialis 

 and perhaps on A. praecox; also once bred from Pachytelia villosella. 



Geographical distribution: — All Europe; towards the north 

 to southern Sweden, and in Finland.

Male. Again this species is similar to the others, but distinguished 

 by the black abdomen. Head shaped and coloured as in the others, 

 but cheeks more whitish pruinose; the hairs on jowls may be pale or 

 black. Thorax blackish brown or olive, brownish or greyish pruinose, 

 the median stripes sometimes confluent. Abdomen black, shining, 

 sometimes obscurely reddish at the sides of third and fourth seg- 

 ment; the three last segments with somewhat narrow, greyish white 

 pruinose front bands, broader on fifth segment; the marginal bristles 

 on second segment weak or wanting. Hind tibiæ with the bristles 

 in the anterodorsal row dense and equal, with one long bristle. Wings 

 as in the other species; medial cross-vein somewhat infuscated; 

 apical cross-vein slightly concave or almost straight; first posterior 

 cell narrowly open, sometimes just closed. 



Female. Quite similar; third antennal joint nearly twice as 

 long as second. 



Length 9 — 11,5 m. 



G. fasciata is not common in Denmark; Ordrup Mose, Char- 

 lottenlund, Ruderhegn, Grib Skov, Tisvilde, and on Lolland in Kæld- 

 skov; the dates are ^U — ^/e? it is thus like ornata early occurring. 

 As host for the species is Bombus terrestris recorded, and Zetterstedt 

 mentions Anthophora acervorum {retusa), but these records are pos- 

 sibly erroneous; it is possible that it has been bred from Panolis 

 griseovariegata (see Baer 1. c).
