into two sub-sections, viz. : (1) The Pro?clones, the 
Robbing or Rapacious, and (2) the Anthophila , or 
flower-loving Hymenoptera. In the former these are 
Ants, Sand-wasps, and Wasps, in the latter Bees. 
In the Praedones there are the following divisions :— 
(1) Ileterogyna , which contains the Ants. (2) Fossores 
which contains the Sand-wasps. (3) JDiploptera, con¬ 
taining the true Wasps. 
There is a distinguishing mark between these two 
sub-sections, in the shape of the hind-leg, the first joint 
n the tarsus is cylindrical in the Prmdones, enlarged 
and flattened in the Anthophila. 
Heterogyna are divided into the Formicidco , the 
Social Ants, and the Mutillidce or Solitary Ants. The 
economy of the Heterogyna is varied, some form tunnels 
and burrows under the ground, others in decaying trees, 
some suspend their nests from trees. The societies 
consist of males, females, and workers, these latter being 
probably abortive females. The males are always 
winged, the females only for a time. Small as are most 
of the species of British Ants, their economy is truly 
marvellous, even amid the many marvels of the insect 
world. “ The industry of the Ant,” to quote the 
words of Mr. F. Smith, “ is a household proverb ; when 
their habitations are by any means injured or destroyed, 
no time is lost in useless despair—one spirit animates 
each individual—simultaneously they set to work to 
repair their misfortune—unceasingly they labour— 
nothing damps their ardour or abates their industry— 
until as if by magic hand, their habitation again rises 
to its former height and beauty, and all trace of ruin 
has disappeared.” The Social Ants are distinguished
