NEW CLASSIFICATION OF THE HEMIPTKKA.— Prof. Schiikltehas proposed the following classification of the Hemiptera,which is probably the best yet suggested, and is based on amore profound study of their external anatomy than has beenpreviously made. It will be noticed, however, that the lice(Pediculina) are not included, though he regards them asforming a separate division (,) of equal valuewith the Heteroptera and Homoptera. He does not seem toinclude the Mallophaga among the Hemiptera. The familiesof the Homoptera are not characterized. I. Gena? (cheeks) hollowed out, to receive the first pair of coxae.[Posterior pair of hinged, provided with femoral grooves.] Suborder HOMOPTERA. II. Genae entire, remote from the coxae. Suborder Posterior coxae acetabulate, rotating, with no femoral grooves. Trochalopoda. a. Metathoracic epimera laminate, nearly concealing the first ventral segment [t the abdomen. 1. Ante
