464 THE ZOOLOGIST. 



A communication from Prof. Newton contained the description of a new 

 species of bird of the genus Drepanis, discovered by Mr. R. C. L. Perkins 

 in the island of Molokai, Sandwich Islands.— P. L. Sclater, Secretary. 



Entomological Society of London. 



November 8, 1893. — Henry John Elwes, Esq., F.L.S., F.Z S., 

 President, in the chair. 



Messrs. H. J. Turner, F. W. Urich, and J. C. Webb were elected Fellows. 



Mr. F. Merrifield exhibited some low-temperature forms of Vanessa 

 atalanta, artificially produced, which showed a great reduction in the area 

 of the scarlet bands on the wings, and a great increase in the area of the 

 white and bluish markings. 



Professor E. B. Poulton described and illustrated, by means of a map, 

 a simple method for showing the geographical distribution of insects in 

 collections. Below the name-label of the genus, and of each species, were 

 placed coloured slips of such a size as to be distinctly visible at a distance, 

 and the colours, with one exception, corresponded with those made use of in 

 the map at the beginning of vol. i. of Dr. A. R. Wallace's ■ Geographical Dis- 

 tribution of Animals.' The exception referred to was the Palsearctic Region, 

 which was coloured blue, instead of pale brown as in the original. Framed 

 maps of the same kind, arid coloured in the same way as the one he exhibited, 

 were to be placed in museums, so as to be readily seen from various groups 

 of cabinets. In these maps the names of the Regions, and numbers of the 

 Sub-regions, were distinctly printed, so that they could be read at a con- 

 siderable distauce. Prof. Poulton added that the method he had described 

 was being gradually introduced into the Hope Collections at Oxford. 

 Mr. McLachlan stated that a somewhat similar plan had been adopted in 

 the Brussels Museum by M. Preudhomrae de Borre. 



Dr. Sharp read and criticised an extract from Livingstone's ■ Expe- 

 dition to the Zambesi, on the habits of a small fighting Ant. 



Prof. Poulton read a paper " On the sexes of larvse emerging from the 

 successively laid eggs of Smerinthus populi" and Mr. Merrifield, Dr. 

 Sharp, and the President took part in the discussion which ensued. 



Mr. W. L. Distant communicated a paper entitled " On the Homopterous 

 genus Pyrops, with descriptions of two new species." 



The President read a paper, by himself and Mr. J. Edwards, entitled 

 11 A revision of the genus CEiieis" which he characterized as the most 

 cold-loving genus of butterflies. He also exhibited his complete collection 

 of species of this genus, which was said to be the finest in the world. — 

 H. Goss, Hon. Secretary.
