The gigantic Tenebrionid;e of tropical Africa have been monogi-aphed by myself in the Transactions of tho 

 Zoological Society, and in the Arcana Entomologica, Vol. II , and the singular Australian Ilelseus, by the Marqtiis 

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

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

 Cossyphus. Many Russian, Persian, and Siberian species are described by various Russian Entomologists, in 

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

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



The Stenelytra (p. S33), have also received considerable attention ; the (Edemerida: of Europe having been mo- 

 nographed by Schmidt in the Linna-a Entomologica, whilst the transformations of Ilelops ater, Melandrya scr- 

 rata, Pyrochroa coccinea, Mordella fasciata, CEdemera seladonia, Boletoph.agus agaricola, and Diaperis Boleti have 

 been observed by Dufour and Pen-is in the Annals of the French Entomol. Soc, and those of Orchesia niicans by 

 Brasellmann. 



The Noto-^cides (p. 537), of Europe h.ave also been monographed by Schmidt in the Entomol. Zeitung, others have 

 also been described by the Marquis de la Ferto in the Annales of the French Ent. Soc, Vol. XI., and by Lucas in 

 the Revue Zoologique. 



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

 and some beautiful Australian species of Helopida» 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 

 tliJ Linn.ican Society; and by myself, in the Trans, of the Entomol. Society ; and it is now ascertained that the 

 Triungulinus or Pediculus MelittK is the real larva in its youngest state. Its form, however, is very greatly altered 

 before arriving at full size. 



The great work of Schonherr upon the Weevils, RHYNCIIOPIIORA (p. 539), has been continued, and at length 

 concluded (with the life of its author), in sixteen thick half volumes, and two supplemental Mantissa;. Of this 

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

 volumes consist of a i-evision of the early ones, with great additions inserted into their places ; and from the entire 

 work being deficient in tabular synopses of the numerous gener.a, the investigations of this great tribe of Beetles 

 is more intricate than ever. Great assistance is, however, to bo 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 Ilis- 

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

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

 Zealand are described and figui-ed by White in the Zoology of the Voyage of the Erebus and Terror. Many 

 Australian species by Erichson in Wicgmann's Archives, and by Germar in the Linnxnv Entomologica. Many 

 valuable remarks on the North American species are published by llarris, in his woi-k on the injurious insects of 

 Massachusets ; whilst the Curculionida; of our own country have been revised by Mi-. Walton in a valuable scries 

 of articles in the Annals of Natural History. About 7500 species are now kno\vn. 



The Silesian species have been revised by Schilling, and the Russian ones by Gotsch in the Bulletin of the 

 Moscow Society for 18-17. 



The Xylophagi (p. 512), have been studied to a great extent, and the greater portion of the genera (in fact the 

 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 Silphidae and other clavicorn tribes, notwithstanding the numerical variation 

 in the joints of their tarsi. Many of these groups have been revised by Dr. Erichson in his work on the Cole- 

 optera of Germany, 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 Paussid.-e have been remonographed in my Arcana Entomologica, and the number of 

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

 published by Burmeister in Guerin's Mag. de Zoologie, in which the Paussida) are considered as most nearly alliud 

 to the Car.abidoB ; 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. Soc. Ent. de France, Vol. III. p. 16, by whom ten genera are 

 admitted into the group. 



Several very remarkable genera liave been lately added to the group, esiiccially Aci'ojiis Burmeister, having tho 

 eyes jdaced on foot stalks, LangelanJia Aube, destitute of eyes ; and Stemmoderus Spinola, having the thorax di- 

 lated into rounded tubercles concealing the head. 



Other singular forms are represented in my Cabinet of Oriental Entomology chiefly from India. 



Some additions of great interest to the Longicobnes (p. 544) h.ave also been made. Here, .approaching Spondvlis 

 (p. 545) must most probably be arranged the South American genus IlypocoplLilus, one of tho most singular of 

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

 quired for that of Trictenotoma, an equally remarkable genus from tho East, which I have also illustrated in tlio 

 Cabinet of Oriental Entomology. 



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

 follows : — 



Group 1. Procephalides (head slanting) divided into three families — Spondyliens, Prioniens, and Cerambyoins. 



Group 2. Clinoceph.alidcs (bead vertical) divided into two families— Lamiens and Sapcrdins. 



Group 3. Dereccphalides (head fixed upon a distinct neck) divided into two families— Rhagieus andXepturins. 



Many now and beautiful exotic species of Longicorn beetles are figured and described by Blanchardin the Voyago
