Wednesday, June 3rd, 1908.— Mr. H. Rowland- Brown, Vice-President, in 

 the Chair. 



Mr. H. St. J. Donisthorpe brought for exhibition pseudogynes of Formica 

 sanguinea, caused by the presence of the beetle Lomechnsa strumosa in the nest, 

 from the New Forest. Mr. H. J. Turner, living larvse of Coleophora maritimella 

 on Artemisia, and also a species of Asilid and its prey. Mr. C. J. Gahan, living 

 specimens of a " leaf insect " from the Seychelles, bred in England by Mr. W. H. 

 St. Quintin, probably Pulchriphyllium crur i folium, Serville ; and Lampyridse of con- 

 siderable interest collected by Mr. E. E. Green in Ceylon, and including both sexes 

 of the genera Lamprigera and Bioptoma, the larviform females of which had 

 hitherto been unknown. He called attention also to the existence in China, Ceylon, 

 and the Malay Peninsula of remarkable larviform females greatly resembling in form 

 the females of the American group Phengodini, and being somewhat similarly 

 provided with rows of luminous points. The males of these forms were not yet 

 identified, but he suspected they would prove to belong to genera at present 

 referred to the family Drilidse. Mr. R. Shelford remarked that in several of the 

 Malacoderm Coleoptera from the Malay Archipelago regarded as larval or apterous 

 forms, the males and females were indistinguishable, and underwent practically no 

 metamorphosis. Mr. G. C. Champion, specimens of Dromius angustus, Brulle, 

 and Cryptophagus l^vendali, Ganglb., recently recorded by him from Woking and 

 the New Forest respectively ; also two species of the Staphylinid genus Lepto- 

 lyphlus and one of the Curculionid genus Alaocyba, extremely minute blind insects, 

 much smaller than any known British representatives of the groups in question. 

 Col. C. Swinhoe, several boxes of butterflies taken by him during the present year 

 (1908) in the Canary Islands, chiefly from Grand Canary and Teneriffe, observing 

 that, with the exception of Lycxna webbiana, all the species met with suggest
