Super-family VII CHALCIDOIDEA. 



The largest number of our parasites belong to this series, and they are usually 

 rather stout species with broad heads, elbowed antenmc and more or less 

 metallic colors. The color character is not universal by any means, yet many 

 of our most common species are recognizable by it, while green, blue or 

 metallic species may be, in most cases, safely referred here. A very good 

 example is the minute species that can be had in great quantities from the 

 chrysalis of the common cabbage butterfly. The wings have few or no veins, 

 are often clothed with short hairs, and occasionally wanting altogether in one 

 sex or both. The ovipositor is more or less concealed, and usually issues from 

 the under side of the abdomen before the tip. 



A proportionally small number of the species are plant-feeders, and some of 

 these, like the "joint-worms," are occasionally injurious. Others are hyper- 

 parasites, or prey upon other species that are themselves parasitic in habit, 

 thus acting as checks to the increase of primary parasites.
