Of a series of 93 chrysopid eggs, 7 were parasitized, which represents an egg parasitism of per cent. The total parasitism, from species issuing from the egg and from species issuing from the cocoon, is computed at about per cent. Tliese parasites, as identified by J. C. Crawford, are as follows. Reared from cocoon: ChrysopopJiagus compressicornis Ashm., Perilampus chrysopae Crawford, Geniocerus chrysopae Crawford, Isodromus
