P. ruricola seems to be rare in Denmark, I know only three 

 specimens, all males; Lave Skov near Helsingør (I. C. Nielsen) and 

 in Jutland at Funder and Svejbæk (Esben-Petersen); the dates are 

 ^/g — ^1^. It is recorded as bred from Mamestra serena, Euclidia glyphica

 bare. Antennæ inserted a little above or nearly at the middle of the 

 eye, third joint from slightly longer to double as long as second; 

 arista short, second joint a little or more elongated. Thorax and 

 its bristles as in Plagia; pteropleura with a little bunch of hairs above

 elongated conical; excavation on second segment reaching hind 

 margin; there are only marginal bristles {ruralis, hilaris) or also 

 discai (trepida); second segment without bristles. Legs with antero- 

 dorsal bristles on hind tibiæ strong and unequal; claws and pulvilH
