206 Tachinidae. 



with the hind coxæ hairy behind; posterior femora and tibiæ not 

 fringed; hind femora with or without anterior row of bristles; middle 

 femora in male with a distal posteroventral comb; middle tibiæ 

 with a ventral spine in both sexes. Claws and pulvilli in male some- 

 what elongated. Wings as in Sarcophaga. 



The larvæ live parasitical in Locustids and Acridiids; the female 

 deposits with the ovipositor the larva between the anal processes 

 of the host. 



Of the genus (and subgenera) 14 European species are described, 

 most of them southern forms; 4 have been found in Denmark. Also 

 North American species belong here (Aldrich, Sarcophaga and its 

 Allies, 1916, but the author does not accept the genus). 



The genus is, as seen, quite nearly related to Sarcophaga^ mainly 

 distinguished by the male genitalia and the ovipositor generally 

 present in female. The genus is still unsatisfactorily known; the 

 species seem generally to be rare, except in southern countries.
