Exhibitions, d'C. 



Mr. S. Stevens exhibited a Pieris Daplidice and six examples of Argynnis 

 Lathonia taken by himself, last September, near Dover ; also a dark variety 

 of Pieris napi, which he took at Leenan, Co. Mayo ; two varieties, one very 

 fine and rich in colour, of Pyrameis cardui, and a black variety of Calli- 

 morpha dominula from Dover; and Sesia asiliformis, Choerocampa celerio, 

 and Deilephila livornica from Brighton. 



Mr. F. Smith exhibited a very large collection of Formicidce sent by 

 Mr. Rothney from Calcutta. This was especially interesting, inasmuch as, 

 in many cases, all the forms were present, these being often so dissimilar 

 in appearance as to render it certain that if their history was not known 

 they would be placed in separate genera ; and this had actually occurred in 

 at least one instance. 



Mr. Smith also exhibited, and presented to the Society, the Minute Book 

 of the Meetings of the Entomological Society existing in London from 1806 

 to 1822, in which were copied the minutes of the pre-existing Aurelian 

 Society. This had been given to him by Dr. J. E. Gray. 



The Meeting passed a special vote of thanks to Mr. Smith for this 

 interesting donation to the Society's Library. 



Mr. Butler exhibited a remarkably perfect impression of the wing of a 

 fossil butterfly in the Stonesfield slate. It appeared to be most nearly 

 allied to the now-existing South American genus Caligo. 



INlr. Davis exhibited a large collection of beautifully preserved larvoe of 

 various insects. 



Prof. Westwood exhibited a collection of drawings of the transformations 

 of Indian Lepidoptera (chiefly Heterocera), executed by Major Hunter. 



Prof. Westwood further made some remarks on the habits of the common 

 gnat. He had observed none in his house at Oxford till about July ; but 

 from then up to the present time there were swarms in certain rooms every 

 night, making their presence known by flying to the lights. All were 

 females, which sex alone is known to torment man by its bites. They were 

 carefully destroyed each day ; yet, although both doors and windows were 

 closed, they were daily replaced by a fresh swarm, and he could only account 

 for their presence by supposing they came down the chimneys.
