Ants, Wasps, and Bees. The Section Aculeata is divided into two Sub-sections, named from the habits of the insects—(I)Pn^DOXES, or the Rapacious, (2) Anthophila, or theFlower-loving Hymenoptera. The Prjedones consists of the Ants, Saudwasps,and true Wasps. The Anthophila consists ofthe Bees. The insects belonging tothese two Subsections may bedistinguished by the legs. Inthe Prsedones, the first or basaljoint of the hind tarsus (fig,52, a) is cylindrical, while in the Fig. Wasps Hind Leg. Anthophila, it is enlarged, and more or less flattened. 188 INSECTS. This peculiarity in the Bees will be further noticed inits own place. Subsection 1.—Pe^doni:s.—The Praedones (Prcsdo,a robber) form three Divisions — 1. Heterogyna, con-taining the Ants; 2. Fossores {Fossor, a digger),containing the Sandwasps ; 3. Diploptera, containingthe true Wasps. The two first are easily distinguishedfrom the third, which has the fore-wings folded length-Fig. 53.
