( I ) As an egg parasite of the Gipsy Moth, Anastatus bifasciatus 

 a chalcid, takes first pilace. One drawback is its low powers of distribu- 

 tion, about 250 feet per year, and its power to parasitize only the upper 

 layer of eggs in the mass which is usually three layers in thickness, so 

 that artificial dispersion becomes necessary.

( 2 ) The egg parasite, Schedius Kuvanae, also a chalcid ob- 

 tained from Japan, does not give promise of being able to withstand the
