Mainland of New Guinea. These specimens have a light spot on the primaries; and the secondaries are more elongated than in P. leodamas, Wall., the species we should have expected to find here. They do not differ from the ordinary type of P. polydorus. 4. Description of a new Species of the Orthopterous Genus Phylloptera from Madagascar. By A R T H U R G. BUTLER, F.L.S., F.Z.S., &c. [Received May 23, 1878.] The genus Phylloptera is one of the numerous interesting groups amongst the Orthoptera which exhibit a striking resemblance to leaves, some of them being imitated in a green condition, and others when faded. The species now before me is an admirable example of this adaptation to surrounding conditions, the tegmina being quite like sear and yellow leaves in which the brown patches of decay have begun to appear.
