HETEROPHAGA. 



The species of this series vary greatly in their habits and appearance, 

 but none of them have the abdomen sessile or united for its full width to 

 the thorax, and none of them feed openly upon vegetation by devouring 

 plant tissue. There are collectors of plant products, like honey and 

 pollen, and some feeders in stems and seeds, but the latter habit is rather 

 exceptional. 



Super-family ICHNEUMONOIDEA. 



Contains moderate sized species on the whole, the wings with a well- 

 arranged series of veins, antennae not elbowed, ovipositor attached before 

 the end of the abdomen and sometimes very long. As a whole, parasitic 

 on other insects. 



In this and the other series of parasitic forms the actual records are 

 not always as full and satisfactory as they might be. Many species are 

 never obtained unless actually bred from their hosts, and by no means 

 all the host species in New Jersey have been bred. It has been deemed 

 advisable, therefore, to include those species of wide distribution bred 

 from host insects which are actually known to occur with us. The rule 

 is that a native parasite has the same distribution as its host, and, while 

 there are many exceptions to this, they will hardly be among such species 

 as are included here.
