THE ORDER MYRIAPODA. (P. 482— 48G.) 



The classification as well as the characters of this tribe of insects has advanced towards perfection with rapid 

 Steps since the days of Latreille ; although Naturalists are still as much at variance with respect to their real 

 relations Thus, whilst M. Brandt adopts the views of Latreille, and even M. Gervais (Hist Nat. Ins. Apt., Ill, 

 p. 54), seems inclined to prefer regarding them as vermiform insects rather than as forming a separate class, 

 equal in value to the Insecta, Arachnida and Crustacea, Mr. Newport, taking up the views of Strauss, (Cons, 

 geuer. sur l'anat. des an. art. p 1G) and some earlier authors, considers them as most nearly allied to the An- 

 nelida, placing the sub-kingdom Articulata at the head of the Invertebrata, commencing with the Hexapod 

 insects, followed by the Spiders, Crustacea, Myriapoda, Annelida, and the remainder of the Articulata, (Trans. 

 Linn. Soc, XIX, 271.) 



The three authors above-mentioned, Brandt, Newport, and Gervais, have especially studied these insects. 

 Newport has retained the binary division and names Chilognatha and Chilopoda of Latreille, but u.rvais has 

 adopted the views of the Baron Walckenaer, and employed the name of Diplopoda for that of Chilognatha. 

 The arrangement of .Mr. Newport of the elass given in the Linnsaan Transactions is as follows: — 

 Order I.— Chilopoda Latr ; Syngnatha Leach. 



Tribe 1. Schizotarsia ; Fam. 1. Cemiatiida}, 1 genus. 

 Tribe 2. Holotarsia ; Fam. 2. Lithobiida-, 2 genera. 



Fam. 3. Scolopendrida;, 8 genera. 

 Fam. 4. Geophilidae, 5 genera. 

 Order II.— (Diplopoda Walckenaer] ; Chilognatha Latreille, Newp° rt - 

 Tribe 3. Pentazonia ; Fam. 5. Glomerida», 3 genera. 

 Tribe 4. Monozonia ; Fam. 6. Polyxenidae. 1 genus. 



Fam. 7. Polydcsmidte, t! genera. 

 Tribe 5 Bizonia ; Fam. 8. Julidae, 8 genera. 



Fam. 9. Polyzonida:, 2 genera. 

 Fam. 10. Siphonophorida;, 1 genus. 

 The works of the authors above mentioned, must be referred to not only for descriptions of the 300 known spe- 

 cies of the order, but also for many valuable observations on their structure, anatomy, and development from the 

 egg state, as well as a memoir by M. Waga, on the Myriapoda of the environs of Warsaw ; various detached 

 memoirs by M. Lucas ; the article Myriapoda by It. Jones, in Dr. Todd's Cyclopedia of Anatomy and Physiology, 

 Also a memoir on the genus Scutigera Lam. (Cermatia Illiger), published by It. Templeton, in the Transactions 

 of the Entomological Society of London, Vol. Ill; and a memoir by Mikan, on the Iuli of South America, 

 published in the Isis for 1834. 



In the Supplement to the 4th Volume of the Histoire Naturelle des Insectes Apteres, the Baron Walckenaer 

 has Introduced a new mode of discriminating the difficult species of the genera lleteristoma and Scolopendra, by 

 the number of joints in the Antennae, varying from twenty-five to eleven. 



THE ORDER THYSANURA. (P. 48G— 488.) 



The researches of the Abbe Bourlet on the Thysanurse of the North of France, and of M. Nicolet on those of 

 Neufchatel in Switzerland, must be consulted. The former have been published in the Memoirs of the Sooil Hi - 

 of Lille, (1839), and of Douai, (1818), and the Revue Zoologique, 1845 ; and the latter in the tfemojres de la Boi 

 Helvet. des Sci. Natur, 1842, and in the Annales of the French Entomological Society for 1847, These works, 

 (except the last), with various detached articles on the subject, have been employed bj M. Qervais in his work on 

 these insects, introduced Into the 3rd Volume of the Hist. Nat des Apteres, in w huh the genus Podura i- divided 

 into eight groups or sub-genera, several of which have received Bynonymical names by the different authors 

 above named. Several other genera are added in M. Nicolet's last memoir. 



The Lepismenx' have received the addition of two singuL ir genera, Nieohtea and Campodea, both having the 

 Mite of scales, and very much resembling the larva; of Staphylinidie. 



The relations of this order have also been the subject of consideration ; Burmeister ranging them next to the 

 Orthoptera, whilst Gervais regards the Lepismlda as .N euro;. ten, us insects stopped iu their d. vehement. 



THE ORDER PABASITA. (P. 188.] 



The fine Monograph of Mr. Denny upon the British ipecies of Parusita, has materially Increased our km." ledge 

 of these insects ; a great number of species being for the first time described and beautifully figured in the 

 twenty-Six plates With (Vhioh the Work is illustrated The species are h.re arranged according tO Nitz-ch's dis- 

 tributioii, as published in '..rinar s Magazine, one sub-genus onl.\ being added for the reception "t the in< 

 found on the common Swift, and named Nitzsehia liumi. istcri. Hurtn. M. r's articles on this order In Ul I ■• W r.i 

 Inseotorum, must be consulted, as well as a valuable article on the structure of the mouth "1 the l'edieuli, in tho 

 Liunaa Entoinologica by the same w liter.
