TiuHE in. Kurt/liiiiiiiii. 



This is tlic most e.vtensive tribe in the iainily and the National iMuseuin collec- 

 tion contains many undescribed species. All of the species are genuine parasites 

 and destroy the larvte of several orders, Hynienoptera, Diptera, Coleoptera, etc. 



Dr. A. D. Hopkins, of the West Virginia State Agriculture College, claims,

 Howard described it as having been bred from ('(vidomyia lugiimicoJa Lintner, living
