Carpenter-Wasps. As there are mason-wasps similar in economy tomason-bees, so are there solitary carpenter-waspswhich dig galleries in timber, and partition them outinto several cells by means of the gnaw ings of thewood which they have detached. This sort ofwasp is of the genus Eumenes. The wood se-lected is generally such as is soft, or in a state ofdecay; and the hole which is dug in it is much lessneat and regular than that of the carpenter-bees,while the division of the chambers is nothing morethan the rubbish produced during the excavation. The provision which is made lor the grub consistsof flies or gnats piled into the chamber, but withoutthe nice order remarkable in the spiral columns ofgreen caterpillars provided by the mason-wasp{Odinerus murariiis). The most remarkable cir-cumstance is, that in some of the species, when the CARPENTER-WASPS,C. 53. A B represent sections of old wooden posts, with the cells ofthe carpenter-wasp. In tig.

In another part of this volume we shall see howcertain caterpillars construct abodes for themselves,by cutting off portions of the leaves or bark ofplants, and uniting them by means of silk into auniform and compact texture; but this scarcely ap-pears so wonderful as t
