6S6 INSECTA. 



containing eight families— 1. Longiscutes, [Scutelleridic and Pentatomidtrn. 2. Supericornes, [Coi-eid;i^]. 

 3 Infei-icornes, [Lvgaiidce and Anthocoridie]. 4. Cecigenes, [ryrrhocoris]. 5. Biccllulfts, [Capsid;e]. 0. L)uc- 

 tirostres, [Tingida^ Ciraex], 7. Nudirostres, [Reduviida?. Hjdronietrida;, Saldu, Acanthia]. And 8. Rameurs, 

 [Gerridie]. Whilst the second section, Il.ydrocorises, contains three families, typified by the three genera. Gal- 

 gulus, Nepa, and Nutunecta. Each of thuse families is subdivided to a great extent, and a number of new spe- 

 cies de'=cribed. 



The principle of subdiviBion lias been carried out to its utmost extent, in a more recent work upon the French 

 species of the order by M. Amyut, with a view to the establishment of n new system of nomenclature in wbich 

 every animal shall be kno:vn only by one name ; thus doing a\'\'ay with the generic nomenclature, established by 

 Liim;rus il, Aniyoff wMik Hrst aiipcarid in tlie French Aniiales, and has subsequently been published sepa- 

 rately. The "Wanzcnarti.Licn Inseoten nf II. ScliatVcr has been continued, and a great number of new species 

 represented in it. \<A. Yll contains a revisiun of the rentatoraidie. The publication of the descriptive catalogue 

 of the IIenH]itcra in the collectifjn of the Rev. F. W. Hope, has been continued, and many new genera added, 

 to the family C!oreidai. Schiodte has giv^i^n a revisiou of the Fabrician specie;-^ of Tetyra, in Kroyer's Banish 

 Joui ual of Natural History ; and A, White has descilbed many new species of Scutelleridas in the Transactions 

 of Uie Entomological Society, and in Gray's Zoological iliscellany. Costa has published descriptionsof nu- 

 meious Italian and Sicilian species, whilst Kolenati has described a great number of Caucasian fepucies in his 

 ileletcinata Entomologica, and. Germar, many Cape of Good Hope species in SilbermunnVs Revue Ent<.ini'jl., 

 Vol. V. An excellent monograph of the curious genus Oiitlialmicus, is contained in Fieber's Entomological 

 mi'nographs, as well as a complete illustrated monograph of the Tingid;c. A monograph of the Capsida? has also 

 been published by IMeyen, accompanied by numerous plates. Monographs of the genera Phyllomorjiha. 

 riiymata, and aliied genera, as well as descriptions of numerous singular ne^v genera, have been published by 

 myself, in the Arcana Entomologica, and Transactions of the Entomological Society. 



Fiubci' has also monograjjhed the genera Sigara and Ploa in bis Entumologiscbe iluuographien. 



THE SECTION nOMOPTERA. (P. 507.) 



In the work of Messrs. Serville and Arcyot, above noticed, the Ilomoptera ai'c divided into tivo sections from the 

 place of insertion of the rostrum or promuscis, Sect. I. The Auehenorhynches, in which the rostrum arises from 

 the chin or middle of the under part of the head, divn.led iiitu three families—!. The Cbanteurs, (Cicada Linn , 

 divided into tu'L-nty-i.>ne genera). 2. The iSubtericorues, (Fulgora Linn., and the numerous genera separated 

 therefrom), and 0, the Antericornes, (consisting uf Membracis, Centrotus, and Cercopls, with the numerous genera 

 separated therefrom) ; and Sect. II. The Sterni.irhynches, in which the rostrum appears to arise from the breast) 

 divided into two families, corresponding with the Linnai-an ge'.iera Aphis and Coccus. Thrips audits genci'a 

 forms an appendix to tlie volume, being I'egarded as a distinct order under the name of Physopoda. Eacli of 

 theSK familiea is subdivided into a number of sub-sections, down to the genera, whieli are very numeruus. 



Numerous new Sivedish species of Homoptera are described by Bohemann, in the Swedish Transaetiuns 

 for !s:.l. 



The Cieadidaj have bei.'n enriched ^vith three fine genera, namely, Cy.-it05oma, with the body like a large swollen 

 bladder, and Tettigarea, both from New Holland, and Polyneura, with the fore wings thickly reticulated, fiuni 

 India, Many splendid additions have been made to the Fulgoridic, by ilr, Hope, in the Transactions of the Liii- 

 n;ean Society, and by myself, in the Arcana Entomol , and Cabinet of Oi'iental Entomology, and the family 

 Fulg<:irida; has been entirely revi^ed, and many new additiuual genera described by the Marquis Spinula. in the 

 Aimales of the French Entomol. Society. Mr. ^Vhite has also described several beautiful species in the Aimals 

 of Natural History. Mr. Rowring, who has had the most abundant opportunities of ub^erving the Chinese species 

 Fulgora Candelaria, has never found it emit the si ghtest trace of luminosity. 



The singular genus Derbe of Fabricius has been monographed liy Poheman, in the Swedish Trans., and by 

 myself in the LinnaDan Transactions. 



The very singular tribe of Membracides has lieen carefully studied by il. Leon Fairniaire in the Annals (if tlie 

 French Entomol. Society, and maiiy neA*' and curious species and genera described. I'r, Eui-meister has also 

 illustrated many of the genera, botli of Fulgi.M':d;e and Cercopida?, in his Genera Insectoi-um, and Mr. ^Vlnie hiis 

 described many large eastern species of the latter group. 



The Aphidii have lately been revised by Kaltenbach and llartig. in Germar's Xeitschrift ; and in uur nun 

 country by Mr. Walker in the Annals of Natural History and the Zoologist. In Kaltenbach's "Monographie der 

 Ptlanzenlause," Aachen, 184:}, the one hundred and sLxty-one species known to the author are arranged under 

 twelve genera, divided into two chief sections — 1st. the winged species, with the genera Aphis, Laehnus. Schi- 

 zniieura, Vacuna, Pemphigus, Tetraneura, Chermes, and Phylloxera ; 2nd. the A\'ingless subterranean species, 

 forming four genera, Rhizobius, Fords., Trama, and Paracletus. Many beautiful figures of these insects are 

 given in Ratzeburg's Forst Insecten. A monograph of the curious genus, Monophlebus, is given du the Arcana 

 Entomologica ; Bouche has also described num.-rous species of Coccidai in the Entomol. Zeitung icr l6ii. 



THE OUDEU NEUROPTERA (P. 574.) 



The relations of the Neuroptera, as arranged in the " Animal Kingdurn," have recently been much discussed, 

 and several of the families of which it is here composed have been removed to the order Ortliuptera, especially 

 by SOUK- of the recent Gei-man Entomologists, \\hilst Brulle and Lap'jrte have cut it up into several sejiara Le
