686 INSECTA. 



containing eight families— 1. Longiscutes, [Scutelleridpe and Pentatomidse]. 2. Supericornes, [Coreid^]. 

 3. Infericornes, [Lygajidaa and Anthocoridse]. 4. Cecigenes, [Pyrrhocoris]. 5. Bicellules, [Capsidae]. 6. Duc- 

 tirostres, [Tingida;, Cimex]. 7. Nudirostres, [Reduviidae, Hydrometridse, Salda, Acanthia]. And 8. Rameurs, 

 [Gerrida;]. Whilst the second section, Hydrocorises, contains three families, typified by the three genera, Gal- 

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

 cies described. 



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

 species of the order by M. Amyot, with a view to the establishment of a new system of nomenclature in which 

 every animal shall be known only by one name; thus doing away with the generic nomenclature, established by 

 Linnasus. M. Arayot's work first appeared in the French Annales, and has subsequently been published sepa- 

 rately. The Wanzenartigen Insecten of H. Schaifer has been continued, and a great number of new species 

 represented in it. Vol. VII contains a revision of the Pentatomidse. The publication of the descriptive catalogue 

 of the Ilemiptera in the collection of the Rev. F. W. Hope, has been continued, and many new genera added 

 to the family Coreidoe. Schiodte has given a revision of the Fabrician species of Tetyra, in Kroyer's Danish 

 Journal of Natural History ; and A. White has described many new species of Scutelleridae in the Transactions 

 of the Entomological Society, and in Gray's Zoological Miscellany. Costa has published descriptions of nu- 

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

 Meletemata Entomologica, and Germar, many Cape of Good Hope species in Silbermann's Revue Entomol., 

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

 monographs, as well as a complete illustrated monograph of the Tiugida;. A monograph of the Capsidae has also 

 been published by Meyen, accompanied by numerous plates. Monographs of the genera Phyllomorpha, 

 Phymata, and allied genera, as well as descriptions of numerous singular new genera, have been published by 

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



Fieber has also monographed the genera Sigara and Ploa in his Entomologische Monographien. 



THE SECTION HOMOPTERA. (P. 5C7.) 



In the work of Messrs. Serville and Amyot, above noticed, the Homoptera are divided into two sections from the 

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

 the chin or middle of the under part of the head, divided into three families— 1. The Chanteurs, (Cicada Linn., 

 divided into twenty-one genera). 2. The Subtericornes, (Fulgora Linn., and the numerous genera separated 

 therefrom), and 3, the Antericornes, (consisting of Membracis, Centrotus, and Cercopis, with the numerous genera 

 separated therefrom) ; and Sect. II. The Sternorhynches, iu which the rostrum appears to arise from the breast, 

 divided into two famiUes, corresponding with the Linntean genera Aphis and Coccus. Thrips and its genera 

 forms an appendix to the volume, being i-egarded as a distinct order under the name of Physopoda. Each of 

 these families is subdivided into ft number of sub-sections, down to the genera, which are very numerous. 



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

 for 18i.5. 



The Cicadidffl have been enriched with three fine genera, namely, Cystosoma, with the body like a large swollen 

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

 India. Many splendid additions have been made to the Fulgoridae, by Mr. Hope, in the Transactions of the Lin- 

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

 Fulgoridffi has been entirely revised, and many new additional genera described by the Marquis Spinola, in the 

 Annales of the French Entomol. Society. Mr. White has also described several beautiful species in the Annals 

 of Natural History. Mr. Bowring, who has had the most abundant opportunities of observing the Chinese species 

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



The singular genus Dei-be of Fabricius has been monographed by Boheman, in the Swedish Trans., and by 

 myself in the Linnaean Transactions. 



The very singular tribe of Membracides has been carefully studied by M. Leon Fairmaire in the Annals of the 

 French Entomol. Society, and many new and curious species and genera described. Dr. Burmeister has also 

 illustrated many of the genera, both of Fulgoridse and Cercopidae, in his Genera Insectorum, and Mr. White has 

 described many large eastern species of the latter group. 



The Aphidii have lately been revised by Kaltenbach and Hartig, in Germar's Zeitschrift ; and in our own 

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

 Pflanzenlause," Aachen, 1843, the one hundred and sixty-one species known to the author are arranged under 

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

 zoneura, Vacuna, Pempliigus, Tetraneura, Chermes, and Phylloxera ; 2nd. the wingless subterranean species, 

 forming four genera, Rhizobius, Forda, Trama, and Paracletus. Many beautiful figures of tbese insects are 

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

 Entomologica ; Bouche has also described numerous species of Coccidse in the EntomoL Zeitung for 1844. 



THE ORDER NEUROPTERA (P. 574.) 



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

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

 by some of the recent German Entomologists, whilst Brulle and Laporto have cut it up into several separate
