Even dried seed-pods, nuts andpine-cones may furnish convenient quarters for ant colonies. longispinosus occasionally nests in hickory nuts from which thekernel has been removed by squirrels. Professor C. H. Eigenmann sentme from Cuba some dried bean-pods containing colonies of the paleyellow Camponotus inccqnalis; and Air. AYilliam T. Davis has given me. FIG. 118.

J., each inhabitedby a colony of C. nearcticus. Suspended Nests.—The suspended nests, like the majority of epi-phytic plants, are found only in the forests of the tropics. They aretrue constructions throughout, consisting of earth, carton or silk, builtso as to enclose anastomosing chambers and galleries. Earthen suspendednests, or ant-gardens, were recently discovered by Ule (1905) in theforests of Brazil (Fig. 179). They are constructed by several species ofants (Aztcca , ulci and traili and Caiiiponutus fcnwnitus), which
