There are a number of spider-hunting waspsbelonging to several distinct genera.^ They havea broad head, a robust fore-body, and a spindle-shaped hind-body which is never stalked, thoughthere is a distinct waist. The hind-legs are long andextend far beyond the body. These legs give themgreat powers of running, and they may frequently beseen racing over the ground, or on tree-trunks andpalings in search of their prey, the wings andantennae in rapid vibration, as though the waspsare labouring under considerable excitement. Thereare some differences in the method of working :thus, Calicurgus will seek for a ready-made hole inpreference to mining one for herself. Pompilus,though a true and efhcient miner, believes in thecookerv adage— hrst catch yowY hare —for she. Photo by] [E. Step. Emperor Cocoon. This cocoon is constructed on the principleof the lobsler trap reversed. The narrowend consists of straight threads «hos«- endsconverge, so that it is easy to get ovit, butdifficult to get in. Calicurgus, Pompilus, Pepsis, etc. Marvels of Insect Life, catches her spider before digging a hole to put it in. It is probable that this planmay frequently lead to the nest being ready first, owing to the secured prey beingcarried off by another wasp whilst mining operations are in progress. Fabregives a detailed account of some experiments he made in order to test her sense of locality, and to ascertain how she wouldbehave under certain conditions. A Pompilusthat he had watched catch and sting a spiderto render it helpless, left her prey on a tuft ofvegetation whilst she proceeded to make a burrowto receive it. She does not wait until the burrowis finished before looking for the vic
