Obsehvations.—Now that it lias been satisfactorily ascertained liy various competent observers
that the species of PaussidiE frequent the nests of different species of ants (not white ants), it is to be
hoped that oni- Indian and Australian collectors will add considerably both to our knowledge of
new species, and to our cabinets, by the capture of specimens' of some of those already described.
Fifty-two species of this family are figm-ed in my Ar-cana Entomologica, and ten others subsequently
discovered, ai-e noticed in the Fifth Volume of the Transactions and Proceedings of the Entomological
