except in a few cases, is always fully developed and longer than the 

 marginal, while the stigmal vein is never very short. The few forms 

 without a postmarginal vein have the submarginal vein ending in a 

 stigma {BcToiieiini and Sce/io). 



The species falling in the groups confine their attacks principally 

 to the eggs of orthopterous and hcmipterous insects.
