 Gibraltar itself, and the remainder on the European side of the Straits, and about 

 one hundred and sixty species of moths. 



Dr. P. B. Mason exhibited a number of specimens of a South European species 

 of ant — Crematogaster scutellaris, Oliv. He said that the specimens were all taken 

 in the fernery of Mr. Baxter, of Burton-on-Trent, and had probably been imported 

 with cork. 



Mr. O. E. Janson exhibited a pair of Neptunides Stanleyi, a species of 

 Cetoniidce, recently received from Central Africa, and described by him in the 

 February number of " The Entomologist ; " also some varieties of N. polychrous, 

 Thorns., from the Zanzibar district. 



Dr. N. Manders exhibited a number of Lepidoptera collected by himself in the 

 Shan States, Burmah ; also a collection of Lepidoptera made by Captain Raikes in 

 Karenni. 



Mr. McLachlan exhibited over 400 specimens of Neuroptera, being a portion of 

 the collection formed in Japan by Mr. H. J. S. Pryer. They represented nearly all 

 groups (excepting Odonata, now in the hands of Baron De Selys). Some of the 

 Ascalaphidce, Panorpidce, and especially Triclioptera, were of great beauty; notably 

 amongst the latter was the curious moth-like genus Perissoneura, McLach. 



Dr. Sharp exhibited the peculiar cocoons of an Indian moth, Rhodia Newara, 

 Moore ; these were the cocoons possessing a drain at the bottom in order to allow 

 water to escape, already described in the " Proceedings of the Zoological Society " 

 for 1888, p. 120, where, however, their great resemblance to the pods of a plant had 

 not been alluded to. 



Mr. Enock exhibited, and made remarks on, specimens of Cecidomyia destructor, 

 bred from American wheat.

 Newmarket ; also specimens of Eupithecia jasioneata and Gelechia coiifinis, bred by 

 Mr. Gardner, of Hartlepool.

 Mr. McLachlan, Mr. Verrall, Lord Walsingham, Mr. Jacoby, Mr. Kirby, and others 

 took part. 



Mr. A. G. Butler communicated a paper entitled " Descriptions of some new 

 Lepidoptera- Heterocer a in the collection of the Hon. Walter de Rothschild." He 

 also contributed a second paper entitled " Synonymic Notes on the Moths of the 

 earlier genera of Noctuites." 



Dr. Sharp read a paper entitled " An Account of Prof. Plateau's Experiments on 

 the Vision of Insects." Lord Walsingham, Mr. Jacoby, Mr. White and Mr. 

 Waterhouse took part in the discussion which ensued. — H. Goss, Son. Secretary.
