Natural History, Ur])ana, Illinois, i ? in xylol-balsani, i slide. (Cen- 

 tralia, Illinois, 25 August, 1909. See preceding list of specimens.) 



A species unique in having the slender wings and the long mar- 

 ginal cilia of the fore wings distinctly longer than the greatest width 

 of those wings. By this characteristic alone it is easily separated 

 from all other described species of the genus. Common in Illinois 

 and probably ])arasitic on jassid eggs in wheat straw {Doryccphahis 

 platyrliyiichus Osborn?). Consult the analogous case of IVcstivood- 

 clla a>iicricana in the reference to Girault, 1909, given on a preceding 

 page, though Webster (1. c.) regarded it as a probable parasite of 

 Isosoma hordci (Harris).
