J. Davis, present as a visitor, spoke of the manifesto adopted at St. Louis on 

 December 30, 1919, by the Entomological Society of America, and on January 

 2, 1920, by the American Association of Economic Entomologists, and it was 

 discussed by Dr. Lutz, Messrs. Davis, Lutz and Sherman. 



Mr. Comstock, under the title " Notes on African Lycaenidae," spoke of 

 the development and distribution of this family of butterflies in the Ethiopian 

 region, illustrating his remarks by specimens of about one sixth of the known 

 species, and by the works of Aurivillius (Rhopalocera sethiopica < K. Sv. Vet. 

 Ak. Hand. 1 898-1 899) and Bethune Baker (Rev. African Lycsenesthes < Trans. 

 Ent. Soc. London, 191 0). A large part of the specimens shown were collected 

 by Miss McKenzie, a missionary in the Kameruns. Mr. Comstock, after ex- 

 hibiting maps of Africa, arranged to show its physical characteristics and 

 faunal sub-regions, pointed out that the development of the Lycsenidse was 

 remarkable, constituting one third of all the butterflies ; and the distribution 

 of one of the subfamilies Lipteninse almost confined to the Ethiopian region, 

 West Africa being especially their home ; while the Lycseninse were found in 

 all the sub-regions of Africa. The work of all authors since Linnaeus was 

 reviewed, Hewitson, Trimen and Bethune-Baker having described the largest 

 number of species. 



The following tables of distribution were given :

Dr. Avenoff, present as a visitor, spoke of the isolation of the African 

 Lycaenidae and of the uncertain boundary between the Palaearctic and Ethio- 

 pian regions. He exhibited maps showing a transition region appeared to 

 intervene between them, which might be traced through Arabia even to British 

 India. 



Dr. Bequaert said that Dr. Avenoft's idea of a strict limit for the bulk 

 of the species and an extra limit for straying insects was interesting. He 

 gave the botanical idea of the distribution of acacia as establishing the north- 

 ern limit of the Ethiopian region, and pointed out that it was supported by 

 the distribution of honey birds and snails.
