The South London Entomological and Natfeal History Society: 

 April 24<th, 1890.— J. T. Caerington, Esq., F.L.S., President, in the Chair. 



Mr. F. Warne exhibited a nielanic variety of Hemerophila abriiptaria, Thnb., 

 taken in the London district. Mr. Barrett asked whether this variety had been 

 recorded for any other neighbourhood. Mr. Briggs, in reply, said it was generally 

 known that it occurred in the north and east of London only. Mr. Carrington, 

 referring to the variety radiata of Spilonoma lubricipeda, Esp., remarked that be- 

 tween 1860 and 1870 this particular variety only occurred in a timber yard close to 

 the railway station at York ; he had recently visited the neiglibourhood, and was 

 interested to find that, although the timber yard had been taken by the Railway 

 Company, the variety now occun-ed in fair numbers throughout the whole district, 

 showing the gradual establishment of a certain form of variation. Mr. Tugwell 

 exhibited specimens of the common butter-burr {Petasites vulgaris, Desf.), and 

 made some remarks thereon, mentioning that it was the food plant of Sydrmcia 

 petasitis, Dbl. Mr. Tutt said that at ShefBeld the species was taken in the factory 

 yards on the plants growing among the refuse, but very rarely among the larger 

 plants growing on the river banks. Mr. Rice, on behalf of Mr. H. Syer Cuming, 

 exhibited among other documents the original rules and constitution of the Aurelian 

 Society, bearing date June 1st, 1801 ; the rules and objects of the Entomological 

 Society of London, founded on the Aurelian Society, and dated May 1st, 1806 ; both 

 being signed by the Founders of the two Societies ; a printed book of by-laws of the 

 latter Society, dated 1807 ; an autograph letter and circular, signed by A. H. 

 Haworth, dissolving the Entomological Society of London, dated April 10th, 1806 ; 

 a priced catalogue of Hawoi'th's Collection, sold at Stevens' June 23rd, 1834, and 

 ten following days ; and a catalogue of insects belonging to the Entomological 

 Society, sold at Stevens' April 16th, 1858. 



Mr. R. Adkin read a paper on the " Occasional Abundance of certain species of 

 Lepidoptera in the British Islands." He took for his types several of the commoner 

 species, including Pieris brassicce, L., Colias Edusa, Fl., Vanessa cardui, L., Plusia 

 gamma, L., &c. Having reviewed the known cases of migration, and the efPects of 

 meteorological conditions upon these insects, he concluded, that although immigration 

 alone would sometimes account for a species being unusually common, the cases of 

 exceptional abundance occasionally observed were, he thouglit, due to immigration 

 taking place at a time when meteorological and other conditions were favourable to 

 the economy of the species effected. Messrs. South, Tugwell, Barrett, Carrington, 

 and others took part in the discussion which followed. 



May 8th, 1890.— The President in the Chair.

 so-called whistling tree, Acacia fistula, from Lower Egypt. — H.W.Baekee, Hon. Sec.
