682 INSECTA. 



belongs to Latreille's Xylophili. See my papers on these two genera in the fourth volume ot the Transactions of 

 the Entomol. Soc. of London. 



The Xylophili (p. 524), have been entirely revised by Dr. Burmeister in his Handbuch der Entomologie, and a 

 great number of new genera and species described. His distribution of the Xylophili is as follows : — 

 Section 1. Head in both sexes unarmed or with a minute tubercle. 



Families 1. Cycloc phalidae (corresponding with the genera Hexodou and Cyclocephala, placed by 

 Latreille at the head of the Rutelidaj. with numerous additional allied genera) ; 2. Strategid» 

 (composed of eleven genera, chiefly described by Kirby and Hope.) 

 Section 2. Head of the males, horned or tubercled. 



Families 3. Phileuridse, 4. Oryctid;e, 5. Dynastidae, 6. Agaocephalidie, each being typified by the 



genus of the same name, but now divided into numerous genera and with great additions . 7. 



Amphibola, consisting of the three new anomalous genera, Pantodinus, B. Cryptodontes Dej 



(Leptognathus Westw.), and Xenodorus De Breme. 



The Dynastidae have been further illustrated with figures in Dr. Burmeister's Genera Insectorum, whilst Latreille's 



second division (Rutelidse) has been revised in his Handbuch and divided into seven families— Chasmodiidae, 



Macraspidida?, Parastasiidoe (typified by Parastasia Westw. a singular Eastern genus) Rutelidae, Pelidnotidae, 



Chrysophorida-, and Areodidte. The genera allied to Chrysophora have also been investigated by Guerin (Revue. 



Zool. 1844), and some beautiful species figured by Sturm in his new Catalogue of the Coleoptera. 



The genera allied to Anoplognathus have also been monographed by Dr. Burmeister, who has divided them into 

 two families — Anoplognathidse and Geniatidae : the former consisting of four sub-families — Anoplognathi genuini, 

 Platycoeliidae, Brachystemida?, and Adoretida- ; and the latter into the Leucothyreidae and Geniatidae genuinae. 



The Melolonthides have been carefully studied by Mulsant, who has divided thein into fifteen genera divided into 

 four branches, namely, the Melolonthaires, Sericaires, Anomalaires, and Hopliaires. 



Dr. Burmeister's great division, Phyllophaga, is of wider extent than that so named by Latreille, being formed 

 of two primary groups characterized primarily by the structure of the claws of the tarsi and named Phyllophaga 

 Systellochela and Ph Chnenochela. The first of these groups is also divided into two sections, 



A. Farinos e, having the body generally covered with scales and composed of four families, 1. Heterochelidas, 



2. Gymnolomidae, 3. Lepisiidae, and 4. Hopliadae. 



B. Metallic:!-, also composed of four families, 5. Anisopliad e (including Anomala, Euchlora, Mimela, &c), 



6. Rutelidae (divided as above mentioned into seven sub-families) ; 7. Anoplognathidae (divided as above 

 mentioned), and 8. Geniatidae. 



The second group i ha-nochela has not yet been published by Dr. Burmeister, but it includes the Melolonthae and 

 other genera forming the first half of Latreille's Melolonthides. 



A number of genera allied to Melolontha, collected by Mr. C. Darwin, has been described by Mr. Curtis in the 

 nineteenth volume of the Linnaean Transactions, and others from New Holland by Dr. Erichson. A monograph of 

 the genus Popillia is publised by Newman in the Trans. Entom. Soc. 



Some splendid insects of doubtful affinity, having Scarabams longimanus for the type, have been formed by Mr. 

 Hope into a family Eucheirida?. It has been considered by Mr. Hope as allied to the Dynastidae, by Klug and 

 Erichson to the Melolonthidae, and by Burmeister to the Trichii. Figures of both sexes of two of the most remark- 

 able species (Mac Leayii and Dupontianus) with details, are given in my Cabinet of Oriental Entomology. 



The splendid section of the Melitophili has received many fine additions, and the synonymy of the species des- 

 cribed by previous authors, especially those contained in Gory and Percheron's monograph, has been thoroughly 

 sifted. The chief works to which (in addition to those noticed in our former edition) reference must be made, are 

 Dr. Burmeister's Handbuch der Entomologie, to numerous papers by Dr. Schaum published in the Annals of the 

 French Entomological Society, in Germar's Zeitschrift, and separately, and to my Arcana Entomologica, in which 

 the Goliathides have been especially illustrated, and many new forms described and figured. A number of new 

 species of Melitophili have also been described by Hope and Schaum in the Transactions of the Entomolog. Soc. 

 of London. The Cremastocheilides have also been carefully illustrated in Dr. Burmeister's Genera Insectorum, 

 and in conjunction with Dr. Schaum in Germar's Zeitschrift. 



The second tribe of the Lamellicorn beetles. Lucanides Latreille, has been monographed by Burmeister in the 

 fifth volume of his Handbuch, in which it is divided into two families, Lucunidae and Passalidae ; the former divided 

 into seven sub-families. Sinoilendridne, jEsalidae. Syndesidae, Chiasognathida?, Lucanidae genuini, Lamprimidte, 

 and Figulidae ; and the latter consisting of the single genus Passalus. The Lucanides are separated by Burmeister 

 into twenty-six genera. 



A catalogue of the Lucanides, with descriptions of the new species in the splendid collection of Mr. Hope, has 

 been published by that gentleman, in which a new plan of distribution of the species composing Burmeister's 

 group Lucanidae genuini has been proposed, and in which the whole of the species are retained under the old 

 genei-ic name of Lucanus. Many species of this family have also been described by Mr. Hope and myself in the 

 Linnaean Transactions, and in the Transactions of the Entomologica] Society of London. Two remarkable genera 

 from New Zealand. Mitophyllus and Dendroblax have been described by Pa-ry and White. Two supplements to 

 the monograph on the Passalidaa has also been published by M. Percheron. 



The investigations of the HETEROMEROUS MELASOMATA (p. 530—532), has been continued by M. Solier in 

 the Annals of the French Entomological Society, and in the Memoirs of the Royal Society of Turin. A number 

 of valuable papers have also been published by Mr. Waterhouse in the Annals of Natural History, and descrip- 

 tions of many species from South America, described by Mr. Curtis in the Linnaean Transactions. 



The Blapsides have been reviewed by Fischer von Waldheim in the Bulletin of the Moscow Society.
