Spiders. 384 AMERICAN SPIDERS AND THEIR SPINNINGWORK. I obtained no other species from these nests, but cannot aftirin that no other escaped.' It may be a question, perhaps, whether the mud daubs were made by Chalybion or Trypoxylon; but we have the great authority of the hite Benjamin D. Walsh that the latter species is really a guest wasp, not building and provisioning any nest for itself, but laying its eggs in the nest built and provisioned by the former, thus appropriating for its own future progeny the spider store laid up by the industrious Chalybion for its young. ^ It is curious and suggestive to trace this use and wont from the guest wasp and the cuckoo up to the human species as represented alike by the imperial "annexers" of Europe, Africa, and the Orient, and the " land grabbers " of the Indian Territory, the " squat- ., ter sovereigns " of the border, and the . ^^ I Ml' " claim jumpers" of Rocky Mountain ,f mining districts. Among the wasps that provision their nests with single spiders is the common blue digger wasp, Chlorion ciBrulcum Drury (Sphex), which, un- like species hitherto alluded to, bur- rows in the earth. It excavates its egg nest in an incredibly short time, sometimes consuming not more than a minute or a half minute, and then places therein a single egg together with a spider, which is generally a large one. With its front pair of feet it then scrapes back the dirt which it hud withdrawn, frequently stopping to pat it down with its abdomen. When the hole is filled the surface is smoothed to the level of the sur- rounding soil. The large and beauti- ful Elis 4-notata Fabr. (Scolia), (Plate v., Fig. 3), invades the burrows of Lycosids, especially Lycosa tigrina, and the small Priocnemus pomilius Cresson has been taken while carrying a Laterig
