084 INSECTA. 



ot'D'Orlii.ii^ny, by White in tnat nf the Ercl*us and Terror, by myself in the Arcana Entomologica and Caldnet of 

 Oriental Entoroulu;,^y (the furini'i- work cuntaining^ 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 Ijy Dupont, in Guerin'h* Jlag, de 

 Zoologie, and a number of new exotic species has been described by Newman, "White, Buquet, Keiche, Guerin, itc, 

 and a memoir in the Australian Stenochorid33 by Mr. Hope, by whom also a number of splendid Indian species 

 has been published in the Transaction of Linarean 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. 5i0^r,oi) under the geueral name of Pliytophaga, proposed by Dumeril, foi-m the 

 subJL'Ct of a work of great extent undertLiki'ii by M. Lacordaire, entitled a " Monographie des Coleopteres subpen- 

 tumeres de lafamille des Phytophages." of which two volumes have appeared. lathis very valuable work the 

 phytophagous insects are divided into two primary groups :— 



1st. The Apostasicerides, or those which liave the antenn;e wide apart at the base, containing the following 

 tribes, each named after the tyjtical genus — 1. Sagrides. 2. Donacidcs, 3, Criocerides, 4. Megaloiiides. -0. 

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

 Slid. The Metopoce rides, or those who have the antennas close together at the base, consisting of 9. Galerucidea 

 (including the greater part of the Ilalticides), 10. Hispides, 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 G97, (nearly three times as many as are given in Dejean's Catalogue des Coleopteres.) The Clythrides 

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



1. ClythridEc, containing only one genus Clythra with 2^5 speci(.-s, but divided into forty sub-genera. 



2. Babide:e, containing ninety-three species, divided into ten genera. 



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



4. Lamprosomidecp, containii;g seventy-nine species, cli-^-ided into tjire^ genera, and containing, as a species of 

 Lamprosoma, the British Oomorphus Concolor, generally placed in the Byrrhidx-. 



fi. ChlamydeiE, containing 200 species, divided into seven genera. 



This volume contains some very interesting observations on the eases formed by the larvce 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 hi'-^hest 

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

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

 species of the genus Xicma in its present restricted state. 



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

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

 genera of exotic Cassidas has also been pnbhshed 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 Gassida have been carefully monographed by 

 Suffrian in the Entomol. Zeitung, and those of Cryptoeephalus by the same author, in the Linn;ea Entomologica. 

 The transformations of various species have also been studied, namely, those of Clythra and Cryptocephalu'; bv 

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

 Scboltz, in Nova Acta ; Hispa, by Dr. Harris ; and Haltica, by Le Keux. 



The relations of the Clavipalpi (p. 554), have been much discussed, and their affinity with the En^idi^ amon'^ 

 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 Erot_\lus, Triplax, and Tritoma are 

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

 neighbourhood of the Silphidx and Ilydrophilida?. 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 tunes the number 

 described by Duponchel in his monograph published only seventeen years previously. Of these 570 specit-s. ninu- 

 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 Engidiforraes, 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 iE-ithug 



Erotylus. <tc. ^ "' 



The species are for the most part elegantly coloured and marked with spots of diiferent colour.s and thev 

 generally reside in boleti, agarics and other fungi. ' ' ' ^ 



A careful revision of the German Anisotomida^ has been made by S^dimidt in Vol. Ill of Germar's Zeitschrift 

 andbyErichsoninhis German Coleoptera. The minute genus Triehopteryx related to these insects has a No 

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

 inKroyers Naturh. Tiddskrift, 1845. Gillmeisterin Sturm's German Fauna. Vol. XVII. and also Erichson' 

 Gern.an Coleoptera. The transformation., of Triehopteryx intermedia have been observed by Pcrri. ( Vnnall 

 Soc Ent. France), and app..r to prove that the genus is nearly allied to the Brachely tra
