“From the cocoons of the Military Microgaster there often 
issue individuals of a minute secondary parasite—a chalcdd, 
called by Walsh Olyphe viridascens, but which probably be¬ 
longs to the genus Tridymus.” 
****** This species is also parasitized by the Olyphe vir¬ 
idascens mentioned above. The latter, by the way, is iden¬ 
tical with the Pteromalus tabacum of Fitch, who bred it from 
Apanteles congregatus, when parasitic upon the tobacco 
worm ( Macrosila quinquemaculata)
