The other two divisions areless easy to distinguish from each other, but the fol-lowing rules may be sufficient. Heterogyna consists ofthe Social Ants and of the Solitary Ants. The SocialAnts may be distinguished from the Sandwasps by theform of the footstalk by which the abdomen is attached tothe thorax^ and which forms, in some, one scale-likeprojection (fig. 53), or a knot-like lump; in others(fig. 54), two such lumps or nodes. The Solitary Ants may be distinguished from theSandwasps by the female of the former being alwayswingless, while the male is generally toothed or spired atthe apex of the abdomen. When, therefore, an insect has been shown by the legsto belong to the subsection Pr^dones, and by its non- HYMENOPTERA.—ACULEATA. 189 folding wings to belong to one of the two first divisionsin that subsection, its place will be further ascertained Fig. 54.
