orders. Wi^must, howevei-, here restrict oxirselves to a notice of the chief works which have appeared on these 

 diilerent families. 



The " Ilistoire Naturelle des lusectesNeuropteres," by M. Rambur, forming portion of lloret's " Suites a Buffon,"' 

 appeared in 1842, and contains an entire monograph of the order, some portions of which, the Libellulidae, 

 Jlj-rmeleonidse, <Sic. have been very carefully investigated by the author (the Linnrcan genus Libellula alone 

 occujiying nearly three hundred pages). In this work the author has nearly followed the arrangements of Pictet 

 and Barmeister, retaining, however, the wliole of the divisions as portions of the order Neuroptera. His seven 

 divisions are as follows : — ■ 



1. The Corrodentia, containing the Termetidie and Embiidae. 



2. The Psocidse, including Psocus and Coniopteryx. 



3. The Subulicornia, consisting of the Odonata [Libellula] and Agnatha [Ephemera]. 



4. The Planipennes, containing the Panorpidoe, Nemopteridae, Myrmeleonidoe, Nymphidae, Hemerobiidse, and 



Mantispidaj. 



5. The Semblides, containing Raphidia, Semblis, <tc. , 



6. The Perlides. - ;-. 



7. The Trichopteres [Phryganea, Linn.] 



Each of these divisions is subdivided into families and genera, and a great number of species described 

 especially in the groups separated from Libellula, Linn. An excellent paper on the anatomy of some of the 

 genera of this family is given by Loew in the third volume of the Liunaja Entomologica ; and the anatomy of 

 many species is also illustrated in Dufour's Recherches Anatomiques et Fhysiologiques sur les Orthoptercs, les 

 llymenopteres et les Neuropteres, 4to, 1841. 



In addition to Rambur's work above noticed, the student must also consult the following works upon tho 

 Libellulidie : — 



Ilagen Synonymia Libellularum Europa;arum. 



Charpentier Libellulina; EuropeiB, descriptae ac depictse, tabulis XLVIII. 



Selys Longchamp Monographic des Libellulidees d'Europe, followed by numerous detached articles on tho 

 family in the Bulletin of the Brussels Academy, the French Annals, &c. The same author has also 

 pubUshed a complete revision of the Synonyms of the Bi-itish Species of Dragon Flies, 

 Boyer Fonscolombe, Monograph of the Agrionides in Annales Soc. Ent. France, Vol. VII. 

 Evans's British Libellulime, or Dragon Flies, illustrated in a series of lithographic drawings, 8vo, 1345, 

 twenty-one plates. 

 The Ephemeridae have formed the subject of a fine monograph by Professor Pictet, Geneva and Paris, 1843, 8vj 

 with forty-seven plates. In this work the author adopts seven genera. Ephemera, Palingenia, Baetis, Pota- 

 manthus, Cloe, Cajnis, and Oligoneura, founded not only on the characters of the perfect insect, but on those of 

 the transformations of the species of which each is composed. An excellent memoir on the anatomy and trans- 

 formation of Palingenia A^irgo has been published by Cornelius. 



The Perlides have been monographed by Newman, and by Pictet in his Histoire Naturelle generale et parti- 

 culicre des Insectes Neuropteres ; famille des Perlides, Geneva, 1841, 8vo, fifty-three plates, in whicli work the 

 author admits only six genera, Kollai-ia, Eusthenia, Pteronarcys, Perla, Capnia, and Nemoura The whole of 

 these species are described and figured with great care. A remarkable peculiarity has been observed by Newport 

 in a species of Pteronarcys, namely, the retention in the perfect state of the external branchiaj of the larva in 

 addition to the ordinary series of spiracles of the Imago. 



The Hemerobiida>, of Belgium, have been monographed by Wcsmael in the Bulletin of the Brussels Academy, 

 and the British species have been illustrated by Evans in the Trans, of the Entomol. Society of London, A'ol. V. 

 A remarkable insect which inhabits the freshwater sponge has formed the subject of communications by myself, 

 and by Professor Grubc and Mr. Ilaliday, by whom it is regarded as the larva of Ilemerobius fuscus. 



A systematic di::tribution of the Ascalaphides has been published by A. Lefebvre in Guerin's Magasin da 

 Zoologie ; a monograph on Nemoptera by myself in the proceedings of the Zoological Society ; Dr. Klug has also 

 given a monograph on Panorpa and Nemoptera in the Berlin Transactions ; the Panorpid;>; have also been 

 revised by myself in the Transactions of the Entomol. Society of London. Dr. Erichson has published a mono, 

 graph of the singular genus Muntispa, in his Entoniograpliien ; and a monograph on Raphidia has also been pub- 

 blishcd by Schneider. 



In addition to the fine monograph of Pictet upon the Phryganea; (Order Trichoptera Kirby; family, Pliclpennes 

 Latreille) noticed in our former supplementary notes, and the general works of Rambur, Burmeister, tho first 

 part of a work by Kolenati has recently appeared at Prague, entitled Genera et Species Trichopteroruni, Pars 

 prior, 4to, with three plates. This workjiromises to be of great service in the investigation of this difficult family. 

 The first part comprises only the first family, Ileteropalpoidea, containing the species liaving tho maxillary palpi 

 of the two sexes dissimilar, divided into three tribes — 1. Limnophiloidea, divided into thirteen genera ; 2. Phryga. 

 neoidea, three genera ; 3. Sericostomoidea, twelve genera. Tho family Isopalpoidea, or those species having the 

 maxillary palpi alike on both sexes will form the subject of a second part. 



THE ORDER HYMENOPTERA. (P. 581.) 



Tho Histoire Naturelle des Insectes ilymeneopteres, commenced by Count Saint Fargeau (in which tho 

 system proposed by him of arranging the families according to their habits) has been completed in four thick 

 volumes, 8vo. The first of these volumes contains the groups which live in societies which are either perennial
