The walls of the cells previously noted, and also the spines, are a lighter green than the body of the egg, and are translucent. As the time of emergence approaches, the egg assumes a light russet shade. The average span of time, from laying to emergence of larva, is 8 days. The eggs are heavily parasitized by a minute Trichogrammid wasp. (Probably T. iniuutuyn.) The egg is illustrated on Plate 5, fig. a..

Most of the species burrow into sand-banks, and provision their cells with caterpillars and spiders. But those best known to us are the mud- daubers. These belong to the genus Pelopceus (Pel-o-poe^us). They make nests of mud attached to the lower* surface of flat stones or to the ceilings of buildings. These

The true wasps (Vespina) may be distinguished from the digger- wasps by having the wings folded on the back like a fan when at rest, and the legs are not adapted to burrowing, being free from spines and bristles. The solitary-wasps {Enmenidae) resemble the
