establishment of genera upon the variations of those organs ; 

 by J. O. Westwood, Esq. F.L.S. &c. The premises in this 

 communication teach " the various formations stated to exist 

 in the antennae of different species of fleas," parasitic on 

 various animals. — 42. Observations on Blight ; by Rusticus 

 of Godalming. A valuable history of the habits of the 

 turnip fly, flea, or beetle. Rusticus conceives that the egg 

 from which the beetle proceeds is laid by the parent beetle 

 on the seeds of the turnips. — 43. Monographia Chalcidum; 

 by Francis Walker, Esq. F.L.S. A continuation from a 

 previous number : the present portion occupies upwards of 

 1 7 pages. — 44. Notes on the habits of Insects ; by Delta. 

 Delightful. — 45. The establishing of the Entomological 

 Society of London. The event, of which the process is here 

 given, was announced on the cover of our July Number. — 



46. The osteology, or external anatomy, of Insects ; by 

 Edward Newman, Esq. F.L S. Letter 1., on the primary 

 parts of insects. This paper argues and instances the ana- 

 logies in the parts of structure of all insects, however dis- 

 similar these parts may seem ; and, in the very limited range 

 of our knowledge of the matter, the paper is the most im- 

 portant and valuable one which has been ever published upon 

 it in Britain. The author's conclusions have, as his foot notes 

 and known eminence in entomology assure us, been carefully 

 drawn from a countless number of instances ; and so his pro- 

 positions are safely founded, and must command adoption ; 

 and, in receiving this adoption, must induce a consistency in 

 the language of entomology, and, with this, a material improve- 

 ment in its condition as a science. By " Letter 1.," prefixed 

 to this contribution, it is inferable more are to follow. — 



47. Entomological Notes ; by Edward Newman, Esq. F.L.S. 

 — 48. Notice of Works on Entomology. — 49. Varieties. 

 In the latter, Mr. Yarrell contributes valuable directions for 

 the preservation of Crustacea. Mr. Evan Webster Lewis 

 details a habit of Microsetia ruficapitella; a minute moth, 

 whose caterpillar causes a curious appearance in autumn on 

 the leaves of rose bushes, marking these leaves " in various 

 directions with broad brown lines, having a narrow black one 

 running down the middle." Mr. Haliday defends Mr. West- 

 wood's conduct from an imputation by the editor in a former 

 number : this is one of the matters noticed by Mr. Westwood 

 in our July Number, p. 380.
