1826'. A paper has appeared by Mr. Bowerbank in the Entomolo- 

 gical Magazine, vol. i. p. 239 ; and a memoir by Mr. Tyrrel upon this 

 subject has also been recently read before the Royal Society. 



Of works devoted to the anatomy, external and internal, ofinsects, 

 we have especially to notice the posthumous work of Lvonnet above 

 referred to, in which his great work on the Cossus is rendered complete 

 by the publication of the dissections of the pupa and imago. The 

 admirable work of M. Straus Durckheim- (second only to that of 

 Lyonnet) vipon the CockchafFer, Melolontha vulgaris, is highly im- 

 portant, illustrating the Coleopterous order as that of Lyonnet does 

 the Lepidoptera *. The Hornet, as an example of the Hymenoptera, 

 has also been treated in like manner ; but an analysis only of the latter 

 has as yet appeared in the 'Bulletin des Sciences Nat.' for ISSC, 

 and in Cuvier's ' Analyse des Travaux' for the same year. 



Mr. MacLeay also has published an elaborate memoir upon the 

 Structure of the Thorax, in the Zoological Journal^, which memoir 

 has since been translated into French and published by M. Audouin, 

 with additional observations, in the ' Annales des Sciences Natu- 

 relles''^. Mr. Newman has also published some osteological sketches 

 in various rmmbers of the Entomological Magazine. 



The numerous memoirs of M. Dufour (published chiefly in the 

 ' Annales des Sciences Naturelles'), Heroldt, Midler, Carus, Suckow, 

 Treviranus, and others, as well as the important memoir of Mr. New- 

 port upon the internal anatomy of the Sphinx ligustri, published in 

 the Transactions of the Koyal Society for the last year, are all of great 

 value, and cannot fail to place this intricate part of the subject upon 

 a firm basis. 



I now proceed to the order Coleoptera, whicli has been more 

 extensively cultivated by modern entomologists than any other group 

 of insects. 



Of works upon this order in general Dr. Klug has had the kind- 

 ness to forward to our Society a memoir published by himself, contain- 

 ing descriptions and numerous figures of the Coleoptera of Mada- 

 gascar''. The second edition of the Catalogue of the Collection of 

 the Count DeJean has been in part published ; and Dr. Perty has is- 

 sued a notice of the Coleoptera of the East Indies'*.

3 A full abstract of the general considerations and laws to which M. Straus has, 

 in his introduction, endeavoured to refer the different modifications of structure un- 

 dergone by the various organs in different groups of articulated animals, has been 

 given by Mr. Doubleday in the Entomological Magazine, Vol. I.
