linden ' in Holland, and by our own member Mr. Shuckard, whose 

 work upon the British species is on tlie point of publication. The 

 latter gentleman has likewise read an interesting memoir upon the 

 habits of tliis group, which has been published in the first part of our 

 Transactions. Dr. Ratzburg has lately published a curious memoir 

 u])on the development of the segments in the apodal larvae of the 

 Hijmenoptera, in wliich (if correct,) he appears to have arrived at 

 some singular facts -'. Mr. W. W. Saunders has likewise recorded 

 some interesting facts relative to the oeconomy of one of the East 

 Indian species of this family, which has likewise been published in 

 our Transactions. Little of novelty upon the family of the Bees has 

 recently appeared either in the way of systematic classification or 

 ceconomical details, if we except the memoirs of the Count de St. Far- 

 geau inserted in the 10th volume of the ' Encyclopedie Methodic|vie ', 

 and those upon Boinbns by Dahlbom ' and St. Fargeau^. 



Neuroptera,Trichoptera. — In like manner, but little novelty has 

 appeared in the order Neuwptcru ' ; but in the T richoptera, or 

 order of Caddice-flies, a splendid work has recently been published 

 by M. Pictet of Geneva'', and which has gained one of the prizes 

 established by Lady Davy in the Academy of that city. Mr. Curtis 

 has likewise published a series of short descriptions of numerous 

 British species in the Philosophical Magazine'. Instances of the 

 ravages of the Termites, or White Ants, have been brought under 

 our notice by Capt. Smee and the Rev. Mr. Hope. 



Orthoptera. — We are indebted to M. Serville for a revision of 

 the order Orthoptera'^, in which numerous new generic groups have 

 been proposed. The Count Fischer de Waldheim has likewise pub- 

 lished a distribution of the Russian species in the last volume of the 

 Bulletin of the Nat. Hist. Soc. of Moscow"; M. Zetterstedt '" a mono- 

 graph u))on the Orthoptera of the North of Europe ; and M. Phillipi 

 a memoir uj)on the Orthoptera of Berlin '". I have already alluded to 

 Mr. George R. Gray's monograph upon tlie Phasmidce of Australia. 

 The same author has likewise just completed an entire monograph 

 upon the family, in which a great number of new genera and species 

 are described ' '.
