INSECTA. 683 



The gigantic Tenebrionida? of tropical Africa have oeen monographed by myself in the Transactions of tho 

 Zoological Society, and in the Arcana Entomologica, Vol. II., and the singular Australian Helaous, bj the Marquis 

 d 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 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 Fald •nnann in his Fauna Transcaucasica. The Pertinites have been 

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



The Stenelytra (p. 538), have also received considerable attention ; the CEdemeridie of Europe having been mo- 

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

 rata, Pyrochroa coccinea, Mordella fasciata, (Edemera seladonia, Boletophagus agaricola, and Diaperie Boleti have 

 been observed by Dufour and Penis in the Annals of the French Entomol. Soc, and those of Orchesia micans by 

 Brasellmann. 



The Notoxides (p. 537), of Europe have also been monographed by Schmidt in the Entomol. Zeitung, others have 

 also been described by the Marquis de la Ferte 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 Ilelopidae 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 

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

 Triungulinus or Pedieulus Melitta; 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 Mantissas. Of this 

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

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

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

 is more intricate than ever. Great 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 lung 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 F.ntomologique. Many remarkable forms from New 

 Zealand 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 Linmea Entomologica. Many 

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

 Massachusets j whilst the Curculionid:c of our own country have been revised by Mr. Walton in a valuable scries 

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



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

 Moscow Society for 1847. 



The Xylophagi (p. 5-42), 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 Silphidie 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 C'ole- 

 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 Audouin, 



Spence, and others. The Paussida bavebeen remonograpbed in my Arcana Entomologica, and the number of 

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

 published by Burmeister in Guerin's Mag. de Zoologie, in which the Paussids are considered as most nearh allied 

 to the Carabidaa ; the species being now ascertained to crepitate Like the Bracfaini, and to reside in ant's d 

 The Bostrichi have been investigate, l by Guerin, Bull. Boc Ent. de Prance, Vol, III. p. 16, bj whom ten genera are 

 admitted into the groan. 



Several verj remarkable genera have been lately added to the group, especially anropis Burmeister, having the 

 eyes placed on root stalks, i.aiigel.uulia A.ube, destitute of eyes ; and Stemmodei us Bpmola, having the thorax di- 



lated into rounded tubercles (-ensealing the head 



other singular forms are represented in my Cabinet of Orii Dtal BntomologJ chiefly from India. 



Some additions of great interest to the Lom unss p. 644) b • n made. Bare, approaching BpondyUs 



(p. 645) must most probably be arranged the South American genus Bypocephalns, one of the m r of 



known Coleoptera. It will, however, be necessarj to establish a separate section forittrecepl 

 qnired for that of Trictenotoma, an equally remarkabli ithel t, which 1 have also illustrated in the. 



Cabinet of Oriental Entomology.
