value. Tlie little Manual of Mr. Newman ', as well as the ' Ento- 

 mological Cabinet' oi" Mr. Samouellc, will also assist in calling the 

 attention of the public to our science. 



The completion of the splendid work of Dr. Peity - upon the in- 

 sects of Brazil, and that of Dr. King upon the insects of Arabia 3, &c. 

 are also especially to be noticed, as well as the series of observations 

 upon the oeconomy of the insects of South America, published by 

 M. Lacordaire in the ' Annalesdes Sciences Naturelles', 'Annales de 

 la Societe Entomologique de France', and ' Nouv. Annales de Mu- 

 seum tl'Histoire Naturelle'; the entomological portion of the great 

 national French work upon the Morea, from the pen of M. Brulle ; and 

 the work of M. Boisduval upon the insects of Madagascar, New 

 Holland, and other islands of the Southern Ocean. Two works are 

 in course of publication in Germany forming Supplements to Pan- 

 zer's great work"*. 



The general principles regulating the distribution of insects have 

 lately attracted considerable attention amongst us. Dr. Horsiield in 

 his ' Lepidoptera Javanica', and Mr-. Stephens in the Introduction to 

 his Systematic Catalogue, have proposed arrangements, founded upon 

 the views developed in that extraordinary work the ' Horse Entomo- 

 logicae ' ; whilst, on the other hand, Mr. Swainson has arrived at se- 

 veral conclusions differing from those of Mr. MacLeay, and which 

 he has especially illustrated in his Zoological Illustrations and the 

 introductoiy treatises to the Natural History portion of Dr. Lard- 

 ner's Cabinet Cyclopaedia. Mr. Newman also has adopted a still dif- 

 ferent series of ideas, which he has developed in his ingenious trea- 

 tise entitled ' Sphinx Vespiformis ", which have, however, met with 

 some opponents, whose observations are published in the Entomo- 

 logical Magazine*. 



The investigation of the natural liistory of insects, as illustrated by 

 their preparatory states, has attracted a considerable shar(> of attention 

 amongst modern entomologists. A volume devoted exclusively to 

 this branch of the science lias recently appeared in Germany from 

 the pen of M. Bouche ''. in which the larvae and pupae of a very great 

 number of insects of various orders are described. 



Much discussion has lately taken place amongst naturalists relative 

 to the circulation of blood in insects, of wliieh remarkable fact, as 

 exhibited in the larvse of certain Neuroptera, an announcement was 

 made by Cams at the (German meeting of naturalists at Dresden in
