Bred from the Pyralids, Mesocondyla concordalis, and Lineodcs, sp. 



The extent and shape of the black markings on the legs and the size 

 vary in this Common North and South American species. C. incerta is 

 regarded by Ashmead, I.e., as identical with (vata, but Crawford, I.e., p. 16, 

 considers it to be a good species, easily separated by differences in the femoral 

 teeth. 



Spilochalcis nunani, sp. n.
