Ten species of Cicadellidae belonging to the tribe Erythroneurini, nine new to science and one new combination, are described here. These are Sirosoma indica, sp. nov., Platytettix variegatus, sp. nov., P. sudra (Distant), Hardiana thiosimilis, sp. nov., Zygina fuscoviridis, sp. nov., Z. minor, sp. nov. Z. unipunctata, sp. nov., Z. acutivertex, sp. nov., Z. bipunctata, sp. nov., and Z. punctulata sp. nov. Out of these species P. sudra is a new combination transferred from Typhlocyba and is redescrided here since the original description was found incomplete. A key for the separation of the genera studied by the authors under this tribe is given.

Two new genera and seven new species belonging to three tribes of Typhlocybinae, i.e., Apetiocellata bifasciata, gen. et sp. nov. (Tribe Dikraneurini); Coloana bischofiae, sp. nov., Mandera horneata, sp. nov., Mandola manaliensis, sp. nov., Plumosa emarginata, gen. et sp. nov. (Tribe Erythroneurini), Amrasca apicoserrata, sp. nov., and Empoasca uniprossicae, sp. nov. (Tribe Empoascini) are described from north-western India.

Two tribes of the subfamily Typhlocybinae are represented in New Zealand, as follows. Erythroneurini: the cosmopolitan genus Zygina is represented by 4 endemic species—toetoe, ramsayi n.sp., dumbletoni, and agni n.sp.—plus zealandica, which occurs in Australia also. Typhlocybini: Typhlocyba froggatti, T. lethierryi, Ribautiana tenerrima, Eupteryx melissae, Kybos smaragdula, and K. betulicola are introduced Northern Hemisphere elements; Matatua montivaga n.gen.s M. maorica (formerly Dikraneura maorica), also endemic, is of uncertain identity in the absence of male specimens. Keys are given for the separation of all taxa, the genera and species are described, and all species except Matatua maorica are figured.

Fourteen new species of the tribe Erythroneurini are described here under seven new genera. These are Spatulostylus variegatus, sp. nov., S. erythromaculatus, sp. nov., S. palniensis, sp. nov., Ratburella unipunctata, sp. nov., Indianella indraprasthana, sp. nov., I. tamaricis, sp. nov., I. delhiana, sp. nov., Cassianeura sexmaculata. sp. nov., Zyginopsis abundans, sp. nov., Z. erythropunctatus, sp. nov., Z. basipunctatus, sp. nov., Z. hindusthanicus, sp. nov., Kodaikanalia primulae, sp. nov. and Erythroneuropsis indicus, sp. nov.
