It feeds its young uponwild bees. Cerceris may be distinguished by the decided constric-tion of each segment of the abdomen. This characteroccurs in Trypoxylon, and in a slighter degree in Phi-lanthus. The antennae are inclined to be clubshaped;the legs strong, with strongspines, and with fringes on thefore-tarsi. The colours are blackand yellow. This genus pro-vides its young with beetles,amongst which are some of thehardest species; Mr. Smith,however, suggests that these,remaining in the damp groundfor some days before the larva) are ready for them, aresoftened by the time they are required as food.

The true Wasps, solitary and social, form the third andlast division of the Predaceous Hymenoptera, Diploptera{AnrXoio, diploo to double ; TTTtpov, pteron wing). Asthis name indicates, the Wasps are distinguished by thelongitudinal folding, or doubling, of the fore-wing. Theeyes of Wasps are kidney-shaped, the tongue is cleft andglandular at the tips; the first and second pairs of legshave one spine at the end of the tibiae ; the hind pair hastwo spines. The claws are simple in the Social Wasps,cleft in the Solitary, and the wings of all have threesubmarginal cells. The first family, the Solitary Wasps, or Eumenidae,form two genera, Eumenes and Odynerus. To the firstbelongs only one British species, E. coarctata (PI. VIII.,fig. 3), which constructs upon the twigs of heath orother shrubs, a small round nest of
