as follows : Mr. White, on Doubledaya viator ; Mr. Hewitson, on 

 new Papilionidae ; Mr. Walker, on new British Diptera ; Mr. Dallas, 

 on the genus Acanthosoma ; Mr. Stainton, on Gracilaria; and lastly, 

 Dr. Wallich's translation of M. Schiodte's elaborate memoir on the 

 Subterranean Fauna of the Caves in Carniola, Trieste, &c, a most in- 

 teresting paper, kindly communicated to us by Dr. Wallich, at our 

 last meeting, and which, I am happy to state, will shortly be published 

 in our ' Transactions.' 



I will now call your attention to various Entomological works and 

 memoirs published elsewhere ; and with regard to these I have to ob- 

 serve, that I have not confined myself strictly to noticing only those 

 which have appeared in the year 1850; some which have come 

 under my observation during the past year for the first time bear the 

 date of the preceding year, and are here noticed. 



In the 'Proceedings of the Linnean Society] of last year, will 

 be found " Further observations on the habits of Monodontomerus, 

 with some account of a new Acarus (Heteropus ventricosus), a para- 

 site on Anthophora retusa ; " by Mr. Newport : and Mr. Westvvood 

 furnishes another contribution to the several papers on the Paussidae, 

 previously read before the Society, by describing two new species of 

 that remarkable family of Coleoptera. 



The ' Proceedings of the Zoological Society ' also contains papers 

 on the branch of Natural History to which we are more particularly de- 

 voted, namely, two papers by Mr. Adam White, one of which is 

 entitled "Descriptions of some apparently new species of Longicorn 

 Coleoptera ; " and the other, " Descriptions of some apparently new 

 species of.Aptera from New Zealand." This latter paper will be 

 found in the 'Proceedings' for 1849, but was not noticed in my last 

 year's Report : the same remark will apply to a paper, by Mr. Wing, 

 containing characters of three new genera and species of Lepidoptera. 



hi the 'Annals and Magazine of Natural History' for 1850, will 

 be found the following papers on annulose animals, viz , several com- 

 munications by Mr. Francis Walker, containing descriptions of 

 Aphides. " Observations on the species of Termitidse of West Africa, 

 described by Smeathman as Termes bellicosus, and by Linnaeus as 

 T. fatalis ; " by T. S. Savage.* " Notes upon the smaller British 

 Moths, with descriptions of some nondescript or imperfectly charac- 

 terized species;" by John Curtis. "Notes on Chalcidites, and
