LO CLASS VIJI. 
The Chaleidie are small Insects, mostly shining with metallic 
lustre, many species of which are able to leap, though that is not 
always the case where the ability might be inferred from the thick- 
ness of the hind-feet. Their larve live parasitically in those of 
other insects, especially of Lepidoptera and Hymenoptera, and also 
in their eggs; they are small maggots without feet. The pupz 
are mostly not included * a web. The number of species of this 
division is extraordinarily great; in Great Britain alone nearly 
1200 species have been found.
