orders. We must, however, here restrict ourselves to a notice of the chief works which have appeared on these 

 different families. 



The " ilistoire Naturelle des InsectesNeuropteres,"by M. Rambur, forming portion of Rorct's " Suites a Buffon," 

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

 My rmeleonida;, <fcc. have been very carefully investigated by the author (the Linnacan genus Libellula alone 

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

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

 divisions are ax follows : — 



1. The Corrodentia, containing the Termetida? and Embiicla . 



2. The Psocidae, including Psocus and Coniopteryx. 



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



4. The Planipennes, containing the Panorpidne, Nemopterida?, Myrmelconiekc, Nyinphida-, Hemerobiidse, and 



Mantispidoe. 



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

 C. The Perlides. 



7. The Trichoptcrcs [Phryganoa, 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 Linnaea Entomologica ; and the anatomy of 

 many species is also illustrated in Dufour's Reeherches Anatomiques et Fhysiologiomes sur les Orthopteres, lea 

 Ilymenopteres et les Neuropteres, 4to, 1841. 



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

 Libcllulidaj : —

Charpentier Libellulina: European, descripta? ac depictrc, tabulis XLTIII. 



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

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

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

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

 Evans's British Libellulinae, or Dragon Flies, illustrated in a series of lithographic drawings, 8vo, 1845, 

 twenty-one plates. 

 The Ephemeridffi 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, Tota- 

 manthus, Cloe, Camis, and Oligoneura, founded not only on the characters of tin- 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 Virgo has been published by Cornelius. 



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

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

 author admits only six genera, Kollaria, 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 branchisa of the larva in 

 addition to the ordinary scries of spiracles of the Imago. 



The IIemerobiida>, of Belgium, have been monographed by Wesmael in the Bulletin of the Brussels Academy, 



and the British species have been illustrated by Evans in the Trans, of the Entomol. Society Of I don. Vol V. 



A ri markable insect which inhabits the fresh water sponge has formed the subject of communications by myself, 

 and by Professor Grubc and Mr. Haliday, by whom it is regarded as the larva of Eemerobius r'uscus. 



A systematic distribution of the Ascalaphides has been published by A. Lefebvre in <■'!• Tin's Magasin dfl 



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



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



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



graph of the singular genus Mantispa, in his Entouiographieii : and a monograph on Raphidia has also been puh- 



blished bj Bchni Lder. 



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

 Latreille) noticed in onr former supplementary notes, and the general works of Rambur, Barmeister, the Brst 

 part of a work by fatolenatl has recently appeared at Prague, entitled Genera et Species Trichopterorum, Para 



prior, lto, with three plates. This work promises to lie ol great service in the invi Jti ■ an. .n of this di Hi cult family. 

 The first part comprises only the first family, Heteropalpoldea, containing tin- species lia\ ing the maxillary palpi 

 of the two sexes dissimilar, divided into three tribes — 1. Limnophiloidl a, divided into thirteen Jl Oera . J. I'ln \_-a- 



neoidea, three genera ; :>. Bericostomoidea, twelve genera. The familj isopalpoidea, or those species having the 



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