SECTS of I.iuiiDcus may be briefly noticed. Descriptions of nuinerou>! 

 species of Anoplura and Pediculi liave appeared in Lyonnet's post- 

 humous woik, illustrated by beautiful figures ' ; whilst Dr. Leach 

 has published the descriptions of several new species, and a new ge- 

 nus named Eiwpus, belonging to the IuUd(e"~. 



A valuable illustrated memoir upon the Thysamira of Ireland has 

 been read before our Society from the pen of Mr. Templeton, in 

 which many new objects are described; whilst the same order of in- 

 sects formed the subject of one of the latest memoirs from the pen 

 of Latreille 3. 



Mr. J. E. Gray has published the descriptions of some new genera 

 of lulides in Griffith's Animal Kingdom* ; and a monograph l)y Dr. 

 Brandt upon the same group appeared in the last volume of the 

 Bulletin of the Natural History Society of Moscow ^. 



The genus Pulex, composing the order Aphaniptera of Kirby, has 

 formed the subject of an elaborate memoir by M. Duges, by whom 

 the real analogues of two pairs of wings have been discovered ''. The 

 structure of the antennae of the different species has been noticed by 

 me in a memoir in the Entomological Magazine 7. 



On arriving at the great group of true Metamorphotic Winged 

 Insects, we find the subject to be so extensive as to require not only 

 a generalized view, but also one extending to each of the orders ; in- 

 deed it w ill be at once perceived how impossible it is to notice, even 

 in the shortest manner, many interesting memoirs containing the de- 

 scriptions of isolated species. This must be my excuse if I should 

 appear to have overlooked the labours of any author. 



Various valuable works have lately appeared in which the oi'gani- 

 zation and classification of insects in general have been detailed : of 

 these may especially be mentioned the w orks of Stephens and Curtis 

 above noticed ; the 3rd and 4th volumes of the ' Introduction to 

 Entomology', by Messrs. Kirby and Spence; the 4th and 5th volumes 

 of the ' Regne Animal' (of Cuvier), from the pen of Latreille; the 

 ' Cours d'Entomologie', by the same lamented author; the 'Intro- 

 duction a I'Entomologie', by M. Lacordaire, formuig one of the vo- 

 lumes of the ' Suites a Buffon'; the ' Handbuch der Entomologie ', 

 by Dr. Burmeister-^ ; the 10th volume of the ' Encyclopedie Metho- 

 dique', The 'Genera des Insectes', of MM. Guei'in and Percheron, 

 and the ' Bulletin Zoologique' of M. Guerin, are also works of much
