FIG. 240. Atenielcs soliciting food from a worker Myrmica. (Wasmann.) Cossyphodites woodroofei, which is abundant in the nests of Plagio-Icpis cnstodiens, has trichomes in a cavity at the tips of its peculiar,ribbed wing-cases. Vastly richer in species are the families Clavigeridab and Psela-phidae, sometimes regarded as a single family and comprising hundredsof species of small red or yellow beetles with short wing-cases and ant-like bodies. Many, if not all, the Clavigeridae and several genera ofPselaphidse are myrmecophilous, but the true guests seem to be confinedto the former family. Some Pselaphids, like our American Decarthronstigmosum, which is sometimes common in the nests of Aplucnogasterfulra and trcatcc, and the species of Batrisns and Chcnniuin, seem torepresent transitions between the synceketes and the symphile Clavigeridae are more interesting because they often show decid-edly symphilic characters, such as antennal modifications and trichomesat the posterola
