 Of these twenty-three papers two relate to Coleoptera, 

 two to Jfemipterti, four to 11 y m p )i optera, seven to Lepidojitera, 

 and four to Ortltoptera. In addition there are four papers 

 which are not confined to the descriptions of, or references 

 to, any one order of insects, viz. Firstly, Mr. Champion's 

 paper which, besides giving an account of an excursion to 

 Central Spain, which he made in company with Dr. Chapman 

 in July 1901, contains lists of, and notes on, the Coleoptera 

 and Hemiptera-Heteropfera collected by them. Secondly, Mr. 

 Guy A. K. Marshall's paper on " Five Years' Observations 

 and Experiments on the Bionomics of Soiith African Insects, 

 chiefly directed to the rnvestigation of Mimicry and Warning 

 Colours, with a discussion of the results suggested by them, 

 by Professor Poulton, F.R.S., and an Appendix containing 

 descriptions of new species of Diptei-a, Hemiptera, Hymenop- 

 tera, and Coleoptera by Mr. E. E. Austen, Mr. W. L. Distant, 

 Colonel C. Bingham, Mr. G. A. K. INIarshall, and INIons. Jules

 Insect," communicated by Professor Poulton ; and Fourthly, 

 Mr. Taylor's interesting anatomical paper communicated by 

 Professor Miall, F.R.S., "On the Tracheal System of 

 Simulium." 



Although the papers on Lepidoptera and Coleoptera are not 

 so numerous as usual, it is satisfactoiy to have published so

 tera, Diptora, and general subjects of interest to Biologists. 



The Memoirs above referred to arc illustrated by twenty-

 Transactions been issued with such a number of plates. Half
