INSECTA. 683 



Tlic gigantic Tencbrionidrc of tropical Africa have oeen monographed by myself in the Transactions of the 

 Zoological Society, and in the Arcana Entoraologica, Vol. II., and the singular Australian Helasus, hy the Marquis 

 de Breme, in his series of monographs on the Ileteromera, and by Mr Hope in the fifth volume of the Transac- 

 tions of the Entomological Society. De Breme has also raonogi-aplied the genera Misolampus and its allies, and 

 Cossyphus. Many Russian, Persian, and Siberian species are described by A'arious Russian Entomologists, in 

 the Bulletin of the Moscow Society, and by Faldermann in his Fauna Transcaucasica. The Pedinites have been 

 revised by Waterhouse in Annals of Nat. Hist., Vol. XVI. 



The Stenelytra (p. 533), have also received consideralile attention ; the rEdemerid;e of Europe ha\'ing l>een mo- 

 nographed by Schmidt in the Linntea Entomologica, ■whilst the transformations of Helops ater, Melandrya ser- 

 rata, Pyrochroa coccinea, Mordclla fasciata. CEdemera seladonia, Boletophagus agaricola, and Diaperis Boleti have 

 been observed by Dufour and Pcrris in the Annals of the French Entoinol. Soe., and those of Orchcsia micans by 

 Bi'aselliiiann. 



The Ndtoxides {p. 537), of Europe have also been monographed by Schmidt in the Entnm'il. Zeitung, others h.ave 

 alsr) been described by the Marquis de la Ferte in tlie Annales of the Freoch Ent. Soe., Vol. XL, and by Lucas in 

 tbr Revue Zoologique. 



Tiie Mylabrides (p. 539), of Barbary have been described by Chevrolat, in Silbermann's Revue Entomol,, Vol. V., 

 and some beautiful Australian species of Helopidse represented in my Arcana Entomologica. The transformations 

 of the genus Meloe, have been investigated by Siebold in the Entomol. Zeitung ; by Newport in the Transactions of 

 tlm Liniiiean Society ; and by myself, in the Trans, ol"' tlie Entomol. Society ; and it is now ascertained that the 

 Triungulinus or Pediculus MelittiB is the realhirva in its youngest state. Its form, however, is very greatly altered 

 before arriving at full size. 



Tlie great work of Scbonherr upon the Weevils, RHYNOIIOPIIORA {p. 539), has been continued, and at length 

 Concluded (with the life of its author), in sixteen thick half volumes, and two supplemental MtintissEe. Of tliis 

 work it will be impossible for us to give even the slightest abstract. Intact, from the circumst;ince that the latter 

 volumes consist of a revision of the early ones, with great additions inserted into their places ; and from ths entire 

 work being deficient in tabular synopses" of the numerous genera, the investigations of this great tribe of Beetles 

 is more intricate than ever. Gfreat assistance is, however, to be obtained from the work of Labram and Imhoff, 

 which contains coloured figures of one species of each genus, but as the work appears in numbers at wide inter- 

 vals, and with numerous additional genera, it will be long before the Iconography of this family can be before us, 

 Waterhouse has published various papers containing descriptions of exotic species, in the Annals of Natural His- 

 tory, the Proceedings of the Zoological Society, and the Transactions of the Entomological Society. Other exotic 

 species are described by Chevrolat and Guerin in the Revue Entomologique. Many remarkable forms from New 

 Ze.aland are described and figured by White in the Zoology of the Voyage of the Erebus and Terror. Many 

 Australian species by Erichson in Wiegmann's Archives, and by Germar in the Linn;£a Entomologica. Many 

 valuable remarks on the North American species are published by Harris, in his work on the injurious insects of 

 Massachusets ; whilst the Cmxulionid-'e of our own country have been revised by Mr. Walton in a valuable serits 

 of artiides in the Annals of Natural History. About 7500 species are now known. 



The Silesian species have been re\T.sed by Schilling, and the Russian ones by Gotsch in the Bulletin of the 

 Moscow Society for 1847. 



The Xylophagi (p. 542), have been studied to a great extent, and the greater portion of the genera (in fact tho 

 whole, with the exception of those forming the genus Scolytus in the text), have been removed from their position 

 in this work and placed nearer to the Silphida^ and other clavicorn tribes, notwithstanding the numerical variation 

 in the joints of their tarsi. Many of these groups have been revised by T>r. Erichson in his work on the Cule- 

 optcra of Gei-many, in which tables are added containing the characters of the exotic genera. 



The natural history of Scolytus destructor, a species injurious to the elms, has been studied by Andouin, 

 Spence, and others. The Paussidaa have been remonographed in my Arcana Entoraologica, and the number of 

 the species nearly doubled, with the addition of variuus new genera. A remarkable memoir on this genus is 

 pui'Ushcd by Burmeister in Guerin's Mag. de Zoologie, in which the Paussida'. arc considered as most nearly allied 

 to the Carabida^ ; the species being now ascertained to crepitate like the Brachini, and to reside in ant's nests. 

 The Bostrichi have been investigated by Guerin, Bull. Soe Ent. de France, Vol. III. p. 10, by whom ten genera ai-e 

 admitted into the group. 



Several very remarkable genera have been lately added to tbo group, especially Acropis Burmeister, having the 

 eyes placed on foot stalks, Langelandia Aube, destitute of eyes ; and Stemmoderus Spin^hL. having the thorax di- 

 lated into rounded tubercles cen^ealing the head 



I Ither singular forms arc represented in my Cabinet of Oriental Entomology chiefly fruin India. 



Some additions of great interest to the Longicornes (p. 544) have also been made. Here, approaching Spondylis 

 {p. 545) must most probably be arranged the South American genus nypocejibalus, one of the most singuLn- of 

 known Coleoptera. It will, however, be necessary to estabUsh a separate section for its reception, as is also re- 

 quired for that of Trictenotoma, an equally remarkable genus from the East, which I have also iUustrated in the 

 Cabinet of Oriental Entomology. 



A valuable work upon the Longicornes of France has been pubhshed by M. Mulsant, -who divides these insects as 



fuUows :^ 



Group 1. Procephalides (head slanting) divided into three families— Spondy liens, Prioniens, and Ceramiiycins. 

 Group 2. Clinocephalides (head vertical) divided into two families— Lamiens and Saperdins. 

 Group 'i. Derecephalides (head fixed upon a distinct neck) divided into two famihes— Rhagieus and Lepturins. 

 Many new and beautiful exotic species of Longieorn beetles are figured and described by Bianchard in tho V'uyage
