Quekett Microscopical Club. 



Friday, May 15, — The 342nd ordinary meeting- of this 

 club was held at 20 Hanover-square, Mr. J. G. Waller, 

 B'^.S.A., President, in the chair. The minutes of the pre- 

 ceding- meeting- were read and confirmed, ballot for new 

 members taken, the additions to the library announced, 

 and other formal business g-one through. 



Mr. Miles exhibted specimens of Aulacodisci from 

 Sendai, in Japan, one of which, A. g-ig-anteus, was in almost 

 perfect condition, which is rarely the case. Mr. Enock 

 read a note on two aquatic Hymenoptera — viz., Prestwichia 

 aquatica and Caraphractus cinctus. The former was the 

 first time of capture since 1862, by Sir J, Lubbock. Mr. 

 Enock also g-ave his reasons for suppressing the name 

 Polynema natans, as it had been clearly proved by the late 

 Mr. F. Walker that it was identical with C. cinctus of 

 Halliday. Mr. Nunne}' g-ave an account of certain disc- 

 like bodies he had found on the stig-mal vein of the wing- of 

 a Chalcid fly, and the matter was discussed by Mr. Ing-pen 

 and Mr. Michael. Mr. Nelson exhibited a portable micro- 

 scope, designed, he believed, by Dr. Ross, and made by 

 Mr. Baker. He also read a paper on "Correcting Errors 

 in Camera Drawings." Mr. Karop read a note on "Illumi- 

 nating Objects with Low Powers by Artificial Light." 

 Votes of thanks were passed for these several communi-
