 ditt'ercnt famiJies. 



The " Histoire Naturelle des InsectesNeuropteres,"by >r. Rambur, forming portion of Roret's " Suites a BulTon," 

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

 JMyrmeleonidte, &c. have been very carefully investigated by the author (the Linna^an genus Libellula alone 

 occupying nearly three Imndrcd pages). In this work the author has nearly followed the arrangements of Pictet 

 and Barmeister, retaining, howevL-i-, the -whole of the divisions as portions of the order Neui'optera. His seven 

 divisions are as follows : — 



1. The Corrodentia, containing the Terinetidie and EmbiidLC. 



1'. The Psocidic, including Psocus and Coniopteryx. 



?^. The Subulieornia, consisting of the Odonata [Libelluia] and Agnatha [E]>hemera]. 



4. The Planipennes, eont.diiing tliu Pan^^rpida^, NL-niopturidLc, Myrmeleonid;e, Xymphidje, ITemerobiidaB, and 



MantispidiE. 



5. The SembUdes, containing Uiii)hidi;i, Sumblis, &c. 



6. The Perlides. 



7. The Triehopteres [Pliryganea, 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 Linntea Entomologiea ; and the anatomy of 

 many species is also illustrated in Dufour's Recherches Anatomiques et Fhysiologiquc-s sur les Orthopteres, les 

 Ilymennpteres et les Nouropteres, 4to, ISll. 



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

 Lihellulida3 : — 



Hagen Synonyniia Libellularum Europxarum. 



Cbarpentier Libellulinaj Em-opete, descriptce ac dGpict;e, tabuhs XLVIII. 



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

 family in the Bulletin of the Brussels Academy, the French Annals, t'^-e. Tlie same author has aliio 

 published a complete revision of the Synonyms of the British Species of Dragon Flies. 

 Boyer Fonscolomhe, Monograph of the Agrionides in Annules Soc. Eat. France, Vul. VII. 

 Evans's British Libellulin;e, or Dragon Flies, illusti-ated in a scries of lithographic drawings, 8vo, 1345, 

 twenty-one plates. 



The Ephemeridie have formed the subject of a fine mouograiih by Professor Pictet, Geneva and Paris. 1843, Svj 

 ■\-\'ith forty-seven plates. In this work the author adopts seven genera, Ephemera, Palingenia, Baetis, Pota- 

 manthus, Cloe, Cienis, 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. Au excellent meniuir on the anatomy and trans- 

 furniLition of Pahngenia Virgo has been published by Cornehus. 



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

 culiere des Insectes Neuropteres ; famille des Perlides, Geneva, 18-41, 8vo, fifty-three plates, in which work the 

 author admits only six genera, KoUaria, Eusthenia, Pteronarcys, Perla, Capnia, and Nemoura The whole of 

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

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

 aildition to the ordinary senes of spiracles of the Imago. 



The Hemerobiidce, of Belgium, have been monographed by "Wesmael in tlie Bulletin of the Brussels Academy, 

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

 A remarkable insect wliich inhabits the fresh water sponge has formed the subject of communications by myself, 

 and liy Professor Gruhc and Mr. Ilahday, by whom it is regarded as the larva of Ilemerobius ftjscus. 



A systematic distribution of the Asealaphides has been published by A. Lefebvre in Guerin's Magasin de 

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

 given a monograph on Panorpa and Nemoptera in the Berhn Tr;ins;ictions ; the Panorpidce have also beea 

 re\ised by myself in the Transactions of the Entomol. Society of London. Dr. Erichson has pubhshed a mono- 

 e:raph of the singular genus Mautispa, in his Entumographien ; and a niunogr;iph on Haphidiu has also been puh- 

 blished by Schneider. 



In addition to the fine monograph of Pictet upon the Phryganea? [Order Trichoptera Kirhy; family, Pliei[ienncs, 

 Latreille) noticed in our former su]ipiementary notes, and the general works of Rambur, Burmeister, the fir.st 

 l.art of a work by Kolenati has recently appeared at Prague, entitled Genera et Species Trichopterorum, Pars 

 ]irior, 4to, with three plates. This work promises to be ot great service in the investigation of this difficult family. 

 The first part comprises only the first family, Heteropalpoidea. containing the species having the maxillary palpi 

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

 ncoidea, three genera ; 3. Sericostomoidea, twidve genera. The family Isopalpoidea, or those species having the 

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



THE ORDER UYMEXOPTEUA. (P. 581.) 



The Histoire Naturelle des Insectes ilymeneopteres, commenced by Cmiit Saint Fargeau (in wbich tlie 

 systeni proposed by him of arranging the families according to tlieir h;ibiL,s) has been completed in lour thiclc
