14 EESULTS FROM GIPSY MOTH PARASITE LABORATORY. 



In the following table and descriptions of species the term " tubercle 

 of hind coxae " refers to a small projection on the ventral side of certain 

 species (fig. 9). The tubercle of the hind femur is the small elevation 

 on the imier side near base and on the lower margin of the femur 

 (fig. 20). 



In all of the figures showing the carina which separates the malar 

 space from the face, the drawings are made facing the left.
