270 THE ENTOMOLOGIST. 



The papers on Coleoptera are two by Mr. David Sharp, in his 

 usual painstaking manner, on *' The water-beetles of Japan," and 

 a " Eevision of the Hydrophilidse of New Zealand " ; and one by 

 Mr. Sidney Olliff, on the life -history of a Cassida from Brazil. 



The most important of the memoirs relating to Hymenoptera 

 is that by the Treasurer, Mr. Edward Saunders, forming the third 

 part of the " Synopsis of British Hymenoptera-aculeata, Apida." 

 It is needless to say that this is written with the usual acumen of 

 that careful author. Mr. E. Saunders contributes also " Further 

 notes on the terminal segments of Aculeate Hymenoptera " ; 

 Mr. Bridgman, " Further additions to Mr. Marshall's Catalogue 

 of British Ichneumonidse " ; Mr. Hockings, " On two Australian 

 species of Trigona" ; and Mr. Cameron, "Descriptions of new 

 species of Tenthredinidse and Cynipidee from Mexico." 



Mr. Douglas contributes the only memoir relating to 

 Hemiptera, " On a new species of the genus Orthezia.'" This is 

 written in the careful manner characteristic of the author, whose 

 habits of close observation are so widely known ; and is illustrated 

 by a plate showing these minute insects magnified. 



Mr. Kirby contributes some " Notes on the Diptera of New 

 Zealand"; and Baron Osten-Sacken, "Facts concerning the 

 importation or non-importation of Diptera into distant countries." 

 This paper is of great interest. The Baron also contributes a 

 very philosophical memoir on comparative Chsetotaxy, or the 

 arrangement of characteristic bristles of Diptera. 



Lastly, there are those two remarkable memoirs, read by Sir 

 Sidney Saunders, on the " Caprification of Figs" and "On the 

 Pediculus melitta of Kirby, and its affinities, with reference to 

 the larvae of Meloe." The latter, as stated by the President in 

 his address, was an " abstruse and closely-reasoned communica- 

 tion," read by one of the original members of the Society in the 

 seventy-fifth year of his age, and within less than a fortnight of 

 his death. 



The President concluded his notice of the late Sir Sidney 

 Saunders with the following remarks, in which all who had the 

 pleasure to know him will concur : — 



" Thus from 1834 to 1884 Sir Sidney Saunders was a contributor to 

 our Transactions, and all his important memoirs have appeared in the 

 Society's publications. It has been truly said that his published writings 

 were far too lew to represent his extensive knowledge of our science.
