4(> MEMOIRS ON ORIENTAL RHYNCHOTA. By G. W. Kirkaldy, F.E.S. With Plates A, B and C. {Read before the Bombay Natural History Society on VMh Nov. 1901) The present memoir consists principally of notices of a portion of the miscellaneous material from Ceylon sent to me for study by my friend, Mr. B. Ernest Green, Government Entomologist of Ceylon, to whom my best thanks are due. I am indebted to this Society for defniying the cost of the coloured plate ; the other has been prepared from drawings made by mj'self, except the homopterous tegminu which have been photographed by a friend. Species of which 1 have recently examined the types are marked with a dagger ( t )• IIOMOPTERA. Family — Fidgoridce. Sub-family— i^iJ^ormffi. Modern authors have restricted the genus Ftdgora, Linn., to the species of which Cicada candelaria, Linn., may be considered as the type, Liternaria, Linn., being employed for Cicada laternaria, Linn , and Pyrops, Spin., for Tettigonia tenebrosa, Fabr., and its congeners. This does not appear to be correct. Laternaria was erected by Linnaeus in 1764 for some species of his origir^al genus Cicada, but as no generic description was adjoined, I have not considered it valid (1). Three years later the same author included these species in his new genus Fulgora la'ernaria being fixed as the type by Lamarck in 1801. In 1839 Spinola monographed the family ( Ann. Soc. Ent. France, VJII, pp. I33-454, Pis. 10-17 ), founding nineteen new genera, of which Pyrops embraced a heterogeneous assemblage of species for which no type was then fixed. A preliminary notice, however, in v^hich all these genera were diagnosed and types fixed (1839, Revue. Zool., pp. 199-206 ), has been overlooked apparently by later authors; in this the type of Pyrops was stated to be candelarius ( Linn. ), a certainly (1) pltos/jJiorea, Linn., is usually quoted as the type of Laternaria, but L. phosjjliorea, Linn., 17G4 ( not Fulgora phosphorea, Linn., 17G7, which is not a Fulgorid ) is the Cirada laternarin Linn., 1758, so ^hat if Laternarin be considered valid as a g^nus, its lype aiust be Inown as Laternaria laternaria (Linn.). In any cnse the specif c name < ught not to be alt-red. It is to be noted that the restoration cf Laternaria as a genus ought not to interfere with the applicitiou here given of Pyrops and Zanna, for Fulgora is syntypical with Laternaria,
