be identical with the cause of the mischief. Wishing to make sure of this being 

 the case, I desired him to take some in the act of biting, and send them to me. 

 This he did the next day, and the specimens sent were, beyond doubt, Stomoxys 

 caldtrans. On seeing him to-day he tells me that he had at one time fourteen cows 

 under treatment. The animals were generally bitten on the outside of the legs, on 

 the shoulders, and, in rare cases, on the neck. In some of the severe cases the 

 joints were so much swollen that the poor animals could not bend their legs to lie 

 down ; and in them the inflammation rose so high as to cause the loss of the outer 

 skin and hair. The flies appeared to prefer the knees and upper portion of the 

 foot in the cow, frequently crawling from thence to the hands of the veterinary, but 

 on him their bite had no injurious efl'ect. And the surgeon, to whom I mentioned 

 the matter, told me that the shoulders of his carriage horses had lately been swollen 

 by the bite of the same fly. — Thos. Jno. Bold, Long Benton, October 16Wi, 1865. 



Entomological Society of London, Octoler 2nd, 1865. — F. P. Pascoe, Esq., 

 F.L.S., President, in the Chair, 



Mr. McLachlan mentioned that he had received a letter from Mr. Stainton, 

 dated Frankfort-on-the-Main, September 25tk, announcing the death of Dr. Schaum, 

 one of the Honorary Members of the Society. 



Mr. W. F. Kirby exhibited the specimen of Sterrha sacraria, taken by his 

 brother at Hove, near Brighton, as recorded in the Ent. Mo. Mag., p. 92. 



Mr. Stevens exhibited part of a collection of Buttei-flies made by Lieut. Do 

 Crcspigny in Borneo. 



Mr. Weir exhibited several specimens of Xylvna petrificata recently taken at 

 Pembury, one of which approached X. semibrunnea in its dark coloration. Mr. 

 Weir also mentioned that he had observed an example of Labia minor use its 

 anal forceps for the purpose of unfolding its wings. 



Mr. McLachlan exhibited some insects taken by the Eev. G. F. Browne in an 

 ice-cave in the Swiss Alps. The entrance to the cave was hermetically sealed with 

 a wall of ice, which had to be broken through, when the roof was found to be 

 thickly studded with the insects. They consisted of two species of Caddis-flies 

 (genus Stenophylax'), and a large ichneumon (genus Paniscus). Mr. Browne asked 

 how these insects could have got into the cave ? and Mr. McLachlan suggested 

 that, with respect to the Caddis-flies, the larva3 might, perhaps, have worked their 

 way up an underground stream, of which there were indications, but this idea 

 would not explain the presence of the ichneumon ; he thought, therefore, that there 

 must have existed some external entrance unknown to Mr. Browne. 



Mr. Evans exhibited an example of Vanessa, Atalanta presenting a mal- 

 formation of the antennse. 



Mr. Saunders exhibited a bulb received from New Granada, which was infested 

 with the patelUform species of Coccus, which caused great destruction to similar 

 bulbs. He remarked, also, that all the individuals were females, and that ho had 

 never been able to find the other sex. 



Dr. Wallace mentioned that a specimen of Argynnis Lathonia had recently been 

 seen near Colchester. 



Dr. Wallace also exliibited the various stages of Bombyx Cynthia (the Aila/nthus 

 silk-worm), and detailed what he had done at Colchester towards the culture of this 

 insect. Ho had planted about half-a-mile of Ailaiithus trees (2,000) ou the railway
