beetles furnish us with many species of large size, and of the most brilliant metallic lustre, among which the Tmesisternus mirabilis, a longicom beetle of a golden green color; the excessively brilliant rose-chafers, Lomaptera wallacei and Ana-camptorhina fulgida; one of the handsomest of the Bupres-tidae, Calodema wallacei; and several fine blue weevils of the genus Eupholus, are perhaps the most conspicuous. Almost all the other orders furnish us with large or extraordinary forms. The curious horned flies have already been mentioned; and among the Orthoptera the great shielded grasshop-
