 C. vulgaris (Schneider), perla (L.), Walkerl (Brauer), viridana 

 (Schneider), tenella (Schneider), prasina (Burm.) and varieties, 

 flava (Scop.), septempunciata (Wesm.), flavifrons (Brauer), and 

 others not yet fuUj identified. Mr. McLachlan stated that he had 

 obtained about 1500 specimens of Neuroptera in all families, 

 during bis recent visit to the Pyrenees, which were being prepared 

 for study. He also exhibited a few Coleoptera from the same 

 district, and remarlied on the e.xtraordinary abundance of the 

 pretty Lamellicorn, Hoplia cairulea, which was so common as to 

 give the meadows the appearance of being studded with multi- 

 tudes of brilliant blue flowers. 



Mr. C. 0. Waterhouse called attention to the numerous reports, 

 which had lately appeared in the newspapers, of the supposed 

 occurrence of the Hessian Fly (Cecidoniyia destructor) in Britain, 

 and inquired whether any communication on the subject had 

 reached the Society. 



The Rev. W. W. Fowler stated, in reply, that he had been in 

 communication with Miss Ormerod on the subject, and that she 

 had informed him that neither the imago nor larva of the species 

 had been seen, and that the identity of the species rested on the 

 supposed discovery of the pupa. 



Paper read. 



Mr. A. H. Swinton communicated a paper, entitled " The dances 

 of the Golden Swift." In this paper the author expressed an 

 opinion that the peculiar oscillating flight of the male of this and 

 allied species had the etfecL of distributing certain odours for the 

 purpose of attracting the females. Mr. Jenner Weir made some 

 remarks on the subject.
