Dermaptera. — 111 the order to which Dr. Leach applied tlie name 

 of Dermaptera, M. Gene has pviblished a monograph of the Italian 

 Forjicula ', and I have read at one of our meetings some observations 

 relative to the respiratory apparatus and sexual organization of the 

 common species. 



Heteroptera. — In the order Heteroptera, or the families of Land 

 and Water Bugs, the elaborate memoir- of M. Dufour upon the 

 comparative anatomy and internal organization of these insects is 

 worthy of its distinguished author ; the classification of M.de Laporte 

 is also especially to be noticed, published in M. Guerin's Mag. de 

 Zoologie ', in which numerous new genera are proposed. The same 

 groups have likewise formed the subject of valuable memoirs by Drs. 

 Burmeister* and Schillings M. Halin has also undertaken the pic- 

 torial illustration of the species in his elegant ' Die Wanzenartigen 

 Insecten ' ". Fallen also has again resumed his publications upon these 

 groups"; and still more recently a memoir by myself upon several 

 curious genera has appeared in the Annales of the Ent. Soc. France'*. 



HoMOPTERA. — In this order Dr. Germar has lately pulilished a 

 valuable synopsis", as well as a monograph upon the G. Cicada "'. 

 M. Guerin has in like manner published a partial synopsis of the 

 order in his Account of the Voyage de Belanger. M. de Laporte 

 has likewise characterized various remarkable exotic groups", whilst 

 our own Transactions are enriched by a memoir of Mr. R. A. Lewis 

 upon several new British genera. The ravages of the Delphax sac- 

 charivora upon the canes in the West Indies have in an especial 

 manner been made the subject of attention by our Society. 



The remarkable family of the Coccidce has likewise been illustrated
