parasites, thus indicating a parasitism of 48.4 per cent. Of a series 
of 93 chrysopid eggs, 7 were parasitized, which represents an egg 
parasitism of 7.5 per cent. The total parasitism, from species 
| issuing from the egg and from species issuing from the cocoon, is 
| computed at about 55.9 per cent. These parasites, as identified by 
J. C. Crawford, are as follows. Reared from cocoon: Chrysopophagus 
compressicornis Ashm., Perilampus chrysopae Crawford, Geniocerus 
chrysopae Crawford, Isodromus wceryae How., Orthizema atriceps Ashm. 
and Heloris sp. Reared from egg: Telenomus chrysopae Ashm.
