were removed to a still larger branch of the tree, which was 

 then enclosed in a large bag of green leno, the larva; ulti- 

 mately forming there loose cocoons and pupating among 

 the leaves, in which the pupae were removed with the greatest 

 of ease to a suitable cage for the moths to emerge in. He 

 had found this method eminently successful, and it had the 

 advantage of entailing a minimum of attention. 



Mr. Lucas exhibited a specimen of the dragonfly. 

 Synipetrum vulgatum, closely related to the common S. 

 striolatinn and with difficulty distinguished from it. It was 

 a male, taken by Mr. A. H. Hamm, of Oxford, at Torquay, on 

 August 15th, 1899. This is the second authenticated British 

 specimen. The other is also a male, taken by Mr. C. Briggs 

 on Bookham Common. He stated that the more prominent 

 distinguishing points were that 5. vulgatum had the principal 

 nervures reddish, and the black line in front of the vertex 

 usually produced downwards along the side of the eyes. 

 There is also an important difference in the genital organs of 

 the male and the vulvar scale of the female. 



Mr. Clark said that he had received ova of Gonepteryx 

 vhamni from Reigate, which were deposited on the stems, 

 the leaves not being yet developed. Mr. Carpenter had 

 noticed a similar occurrence in the spring of 1893, a very 

 early season. Several members stated that the species was 

 common this year, and Dr. Chapman had seen both G. rhamni 

 and G. clcopatravery abundant in South France, but remarked 

 that they seemed to disappear when a period of very hot 

 sunshine set in. 



Under the title of "Wild Flowers at Home " Mr. E. Step 

 F.L.S., exhibited a series of lantern slides from his own 

 photos of indigenous plants amid their natural surroundings, 

 and made a running comment upon them as they appeared, 

 calling attention to those special points in their structure 

 that have direct relation to their habit and habitat, their 

 friends and enemies among insects, birds, and mammals.

Mr. W. J. Lucas, B.A., F.E.S., President, in the Chair. 



Mr. Adkin exhibited a series of Cabera exanthemata, show- 

 ing considerable variation in the position of the transverse 

 lines ; in some instances the first and second lines coalesced. 

 These latter specimens he had received from Mr. Harwood,
