684 INSECTA. 



otD'Orbigny by White in tiiat of the Erebus and Terror, by myself in the Arcana Entoraologica and Cabinet of 

 Oriental Entomology (the former work containing a monograph of the New Zealand species and those of tropical 



Western Africa, allied to Sternotomis). . ^ - . , „ 



An illustrated monograph of Trachyderes and allied genera has been published by Dupont, m GuermsMag.de 

 Zoologie and a number of new exotic species has been described by Newman, White, Buquet, Reiche, Guerin, &c. 

 and a memoir in the Australian Stenochoridie by Mr. Hope, by whom also a number of splendid Indian species 

 has been pubUshed in the Transaction of Linnaean Society. The Philippine Island species are described by New- 

 man in the Entomologist. In all these works the number of genera has been greatly increased. 



The EUPODA and CYCLICA (p. 519—553) under the general name of Phytophaga, proposed by Dumeril, form the 

 subiect of a work of great extent undertaken by M. Lacordaire, entitled a " Monographie des Coleopteres subpen- 

 tameres de la famille des Phytophages," of which two volumes have appeared. In this very valuable work the 

 phytophagous insects are divided into two primary groups :— 



1 st The Apostasicerides, or those which have the antennoe wide apart at the base, containing the following 

 tribes, each named after the typical genus— 1. Sagrides. 2. Donacides, 3. Criocerides, 4. Megalopides. 5. 

 Clythrides, 6. Cryptocephalides, 7. Eumolpides, 8. Chrysomelides. 

 2nd. The Metopocerides, or those who have the antennae close together at the base, consisting of 9. Galerucidcs 

 (including the greater part of the Ualticides), 10. Ilispides, 11. Cassidides. 

 The First Volume is occupied with descriptions of the species composing the first four tribes. 

 The Second Volume which is just published, is confined to the Clythrides, of which the author describes as 

 many as 697, (nearly three times as many as are given in Dejeau's Catalogue des Coleopteres.) The Clythrides 

 are divided into five sub-families or tribes, namely :— 



1. Clythridx, containing only one genus Clythra with 255 species, but divided into forty sub-genera. 



2. Babideic, containing ninety-three species, divided into ten genera. 



3. Megalostomideffi. containing sixty species, divided into five genera. 



4 Lamprosomidea;, containing seventy-nine species, divided into three genera, and containing, as a species of 

 Lamprosoma, the British Oomorphus Concolor, generally placed in the Byrrhidse. 



5. ChlamydeiB, containing 209 species, divided into seven genera. 



This volume contains some very interesting observations on the cases formed by the larvte of the different 

 species, and composed of particles of their own excrement. 



The careful revision of such of these tribes, as have been already published by M. Lacordaire, merits the highest 

 Braise the genera having been rigorously examined, and the species minutely described. It may suffice, in order to 

 show the extent .)f the materials in the hands of the author, to state that he has described as many as 273 

 species of the genus Lema in its present restricted state. 



A great number of species of these tribes are described by Faldermann in his Fauna Transcaucasica. Some 

 beautiful new forms are also described and figured by Mr. Hope in his Coleopterist's Manual. A memoir on the 

 genera of exotic Cassidaj has also been published by Mr. Hope, in the Annals of Natural History, and many 

 species of Hispa and the allied genera by Guerin (Revue Zool.), and Newman, (Entomologist.) A series of 

 papers on the Australian species of Cryptocephalides has been published by Mr. Saunders in the Transactions of 

 the Entomological Society. The European species of Lema and Cassida have been carefully monographed by 

 SufFrian in the Entomol. Zeitung, and those of Cryptocephalus by the same author, in the Linn^a Entomologica. 

 The transformations of various species have also been studied, namely, those of Clythra and Cryptocephalus, by 

 Rosenhauer and Chevrolat ; Colaspis ater by Joly, (Ann. Sci. Nat., Vol. II.) ; Cassida, by Gravenhorst and 

 Scholtz, in Nova Acta ; Hispa, by Dr. Harris ; and Ilaltica, by Le Keux. 



The relations of the Clavipalpi (p. 554), have been much discussed, and their affinity with the Engidie among 

 the Necrophagous Coleoptera, maintained by several authors. This is also the opinion adopted by M. Lacordaire 

 in his very excellent " Monographie des Erotyliens," in which the Latreillian Erotjlus, Triplax, and Tritoma are 

 comprised. Languria is to be referred to the Engido9, and Phalacrus and Agathidium form a family in the 

 neighbourhood of the Silphidje and Hydrophilidae. These views, of course, materially interfere with the tarsal 

 system, but they may be regarded as the exceptions to it, and not as proofs of its inaccuracy. 



M. Lacordaire in his monograph, described 570 species of Erotyliens, being more than six times the number 

 described by Duponchel in his monograph published only seventeen years previously. Of these 670 species, ninc- 

 tenths are natives of the New World. Only three species are described as natives of Asia ; only two of New 

 Holland ; and sixteen of Africa. The family is divided by Lacordaire into two tribes— 



1. The Engidiformes, with the inner lobe of the maxilla unarmed, or with one tooth, composed of fourteen 



genera, including Dacne, Triplax, Tritoma. 



2. The Genuini, with the inner lobe of the maxilla armed with two teeth, including the genera .ilgithus, 



Erotylus, &c. 



The species are for the most part elegantly coloured and marked with spots of different colours, and they 

 generally reside in boleti, agarics and other fungi. 



A careful revision of the German Anisotomidoe has been made by Schmidt in Vol. III. of Germar's Zeitschrift, 

 and by Erichson in his German Coleoptera. The minute genus Trichopteryx related to these insects, has also 

 attracted great attention. See Heer in Entomol. Zeitung, 1843. Allibert in Guerin's Revue Zool., 1844. Schiodte 

 in Kroyer's Naturh. Tiddskrift, 1845. Gillmeister in Sturm's German Fauna. Vol. XVII, and also Erichson's 

 German Coleoptera. The transformations of Trichopteryx intermedia have been observed by Perris, (Annales 

 Soc Ent. France), and appear to prove that the genus is nearly allied to the Brachelytra. 



The French species of the Fungicohc (p. S5t), have also been excellently monographed by M. Mulsant, by whom
