SUBFAMILY ALYSIINAE 1-^4 



The Alysiinae, in so far as their habits are known, are parasitic on the larvae and 

 pupae of Diptera. Some exert an important degree of control on injurious species, 

 while others live as hyperparasites, attacking primary parasites of the family 

 Tachinidae. But the group as a whole is very poorly understood, from the stand- 

 point of biology as well as that of classification. Unquestionably there are many 

 species belonging to this subfamily in New York, but the identification of most of 

 these must await revision of the group.
