240 Tachinidae. 



generally three intraalar bristles. Sciitellum with three marginal 

 bristles on each side, the apical crossing, sometimes a weak hair-like 

 bristle between the apical and the next. Three sternopleural bristles. 

 Pteropleura with a bundle of hairs and one bristle above. Abdomen 

 more or less elongated; excavation on second segment not by far 

 reaching hind margin; there are discai and marginal bristles, second 

 segment with a pair of marginal, or (in non Danish species) without 

 bristles. Legs long with somewhat long bristles; claws and pulvilli in 

 male strongly elongated ; front tarsi in female simple or with the three 

 last joints slightly flattened. Wings with first posterior cell narrowly 

 open or nearly closed, ending a little before apex of wing; discai 

 angle nearly rectangular or more obtuse ; a small costal spine present. 



The species are mainly parasitic on larvæ of Chrysomelids; 

 chalconota (non Danish) has also been bred from Sylepta ruralis \ 

 this species is known to belong to Pantel's group 5. 



Of the genus some thirty European species are recorded, but 

 a number of them are still doubtful. 



The genus Macquartia, the species of whicli seem rather well 

 related to each other, shows nevertheless some peculiar features. 

 Thus grisea (of Danish species) has the thoracic squamula of the shape 

 characteristic of the Rhinophor inae^ somewhat narrowed with inner 

 margin bending away from scutellum, while the two other Danish 

 species have the squamulæ as in Tachininæ; also as regards the chæto- 

 taxy the species show peculiar differences as seen in the descriptions 

 (see Villeneuve: Ann. des Se. Nat. 10, VII, 1924. 12 et 30).
