HYMENOPTERA — FORMICID&E. QT 
but, as Latreille, who proposed the latter name, also introduced the 
Mutillidz into the group, I have thought it more correct to give it a 
distinct name, SopaLeEs (or PuiLopona K.), founded upon the circum- 
stance, not only that the insects are social in their habits, but also be- 
cause the larve are not enclosed in separate hexagonal cells as in the 
wasps and typical bees. 
The single family, Formicrp®, is composed of the well known and 
singularly interesting tribes of ants (which must not however be con- 
founded with the Termitidze or white ants), and which are distinguished 
by their habit of residing in more or less numerous societies under- 
ground ; whence arises the necessity for a great number of individuals 
having the sexual organs and instincts rendered abortive, whereby, be- 
ing freed from the latter, they are the better fitted to perform the 
labours of the community, for which purpose they are moreover desti- 
tute of wings; whilst the males and females are much less numerous, 
possessing wings, and being produced only for the propagation of their 
species. 
The males have the body small, with the antennez and legs long and 
slender (jig. 85.* 1. F. fusca $ 2—5. details of this sex); the females, 
on the other hand, far exceed their partners in size, with the antennz 
and legs shorter and thicker (fig. 85. 6. F. fusca 9 7—10. details of 
this sex). Both these kinds of individuals are furnished with wings

of individuals of which each species is composed. No similar comparative details
