four plates in which the genera are illustrated by magnified figures 

 of the terminal segments of the abdomen with the anal appendages. 



The zeal with which M. De Sclys has prosecuted his studies, by 

 inspecting the collections of France and England, as well as by his 

 researches in Germany, Switzerland and Italy, leads us to hope that 

 he may l)e induced to extend his labours to the fine exotic species of 

 this family, which are very numerous, (being distributed over every 

 portion of the globe) and offer an almost untrodden field of investi- 

 gation. 



In perusing the memoir, two or three things presented themselves 

 connected with the works of British authors ; and although not very 

 important, it will be as well to rectify them, othewise they may lead 

 to incorrect impressions. 



P. 56. LibeUida 7-ubicimda is not noticed by Mr. Stephens ; indeed 

 this Linna;an species was not known in England until Mr. Curtis 

 described and figured it in his ' British Entomology.' 



P. 69. It was Mr. Dale who _^?"^/ discovered Co/'rf?<//a Curtisii, and 

 his friend Mr. Curtis subsequently captured it. Mr. Stephens never 

 saw it alive, but is indebted to Mr. Dale for his specimens. 



P. 84. Mr. Stephens took only o/ie specimen of Gomphus pulchellus , 

 "which w'as most probably transported from the opposite coast. 



P. 108. Dr. Shaw published a figure and description of ^. vuriu 

 in 1806. 



P. 114. ^. n{/(?6fce«s is exceedingly rare in England, and was_^rsf 

 discovered by Mr. Dale, after whom Dr. Leach named it, but unfor- 

 tunately neglected to publish his description. 



P. 160. Mr. Stephens published a description of ^. ooanthopterum 

 in his ' Illustrations' in 1836, which Mr. Curtis seems to have over- 

 looked when he described it in the 16th volume of 'British Ento- 

 mology,' under the name of Agrion rubella. 



It is with pleasure we notice the honourable and gentlemanly 

 feeling which has guided M. De Selys through his labours : instead 

 of being influenced by a narrow and pernicious principle of super- 

 seding the names by which species are already known, he has en- 

 deavoured to do justice to his predecessors by adopting names ac- 

 cording to their right of priority ; an honest example, which we hope, 

 for the welfare of science, to see followed by all our other conti- 

 nental neisrhbours.

May 4th, 1 840.— The Rev. F. W. Hope, President, in the Chair. 



Mr. Yarrell exhibited some larva of Tipiila oleracea, which had 

 proved very destructive to the grass in Golden Square, London. 

 Mr. Hope stated that lime-water, as well as water from the gas ma- 

 nufactories, was very beneficial in destroying them. 



Mr. New^port exhibited the specimen of Geophilus mentioned by
