By Albert Edward Feldman* and Norman S. BAiLEYf 
Department of Biology, Boston University 
The purpose of this paper is to present evidence that the 
ovipositor of the New England species in the genus Cory - 
thucha Stal is of taxonomic value in the separation of the 
species. This work is based upon a study of thirteen species, 
of which over 450 whole mounts have been prepared and 
examined. 
I. Procedure for the preparation of the ovipositor 
To prepare the entire ovipositor for study the abdo- 
men was first separated from the insect and placed in a 
0.5 MM.
