Walker to examme my Homoptera, and the following paper is the result of his labours, irrespective of his papers on the Homoptera collected by Mr. Wallace in the Malay Peninsula and East India Islands, which will be foimd in the 'Journal of the Proceedings of the Linnean Society.'

About five hundred species of this family have been described, and they are divided into twenty-two genera. Of these several are limited in their geographical range ; 'thus Polyneura, Pycna, Tacua, Tosena, inhabit Hindostan and the neighbouring isles; Platypleura and Oxypleura extend from West and South Africa to Hindostan, Java and Amboina ; Zammara is peculiar to America; Tetligades only inhabits Chili ; Thopba, 'Mtigarcta and Cystosoma are Australian ; the range of Dundubia begins in hiB Himalaya, and various species inhabit many of the islands between Hindostan and the open Pacific Ocean ; Tettigomyia is confined to South Africa";: Mogannia, Huechys and Gaaana extend from Hindostan to Java and China, and Huechys also inhabits Australia. Genus PLATYPLEURA, Amyot. Platypleuba arcuata. Fulva, P. ocellatse similis ; caput supra nigricans, litura anlica nigra ; prothorax vitta postice dilatata maculisque quatuor nigris ; mesotho- 4^ rax vittis quatuor furcatis nigris ; abdomen fasciis interruptis apice- que nigris ; alec anticmfulvcc, fusco nebulosce, liluris duabus coslalibus pallidis, maculis marginalibus fuscis ; posticce fusccc, vittis tribus, strigis nonnullis lanceolatis exterioribus slrigaque postica luteis.
