60 REVIEWS. 



In the unavoidable absence of the President, the Right Hon. 

 the Earl of Strafford (late Viscount Enfield), Lord-Lieutenant of 

 Middlesex, the chair was taken by one of the Vice-Presidents, 

 Dr. Archibald Geikie, F.R.S., head of the Geological Survey. 

 Mr. Sydney T. Klein, F.R.A.S., Hon. Secretary and Treasurer to 

 the Society, read a paper entitled, " Thirty-six Hours' Hunting 

 among the Lepidoptera and Hymenoptera of Middlesex ; with 

 Notes on the Methods adopted for their Capture." 



A very enthusiastic discussion followed, in which Dr. Archibald 

 Geikie, Dr. Francis A. Walker, Mr. W. Mathieu Williams, Mr. 

 Basil Woodd Smith, Mr. James Smith, and many others, took 

 part. Mr. Sydney T. Klein, after replying and thanking those 

 present for the cordial way in which they had received his remarks, 

 exhibited in illustration of his paper specimens of the insects 

 referred to, and in addition two queen cells of Apis Ligustica, 

 showing how the wax at the apex had been thinned preparatory to 

 the exit of the queen, and the rent in the side of the cell through 

 which the nymph had been stung and dragged forth by the new 

 queen. He also exhibited cells of Osmia n/fa, the mason 

 bee, from which were released living bees, together with specimens 

 of its beautiful parasite, Chrysis ignita ; also, specimens of N. 

 megachile, the leaf-cutter bee, with its tawny parasite. Triponylon 

 figulus. Mr. Klein also exhibited numerous pupse and cocoons of 

 the species mentioned. Mr. Lant Carpenter showed a portable 

 electric lamp for mining and other purposes ; Mr. Rousselet a 

 polyzoon under the microscope ; and Mr. Sherborne some artifi- 

 cial " Perlitic " and " Schellerization in rock structures." 



A vote of thanks was then passed to Dr. Archibald Geikie, 

 after replying to which he congratulated the Society on the 

 thoroughly practical beginning they had made that night, and 

 brought the meeting to a close.
