dible and maxilla of Arixenia, together with the mandible of Hemi- 

 meriis. — Dr. Malcom Burr, D.Sc, F.L.S. F.Z.S., communicated a 

 paper entitled " A Eevision of the Labiduruhe, a Family of the 

 Dermaptera." The discussion of the affinities of Agriades thetis 

 (bellargus) and A. corydon, adjourned from the December meeting, 

 was resumed by Mr. J. W. Tutt, who exhibited long series of the two 

 species, demonstrating in particular the several forms of A. corydon 

 as occurring in the palsearctic region. He pointed out in detail the 

 nearness of the two Agriadid species in the structure of their eggs, 

 larvae, pupge, imagines, especially noting in the latter case the 

 similarity in the male genitalia. Not only was their environment 

 similar, and their morphological structure almost identical, but their 

 actual range was practically the same. Exhibitions were also made by 

 Mr. G. T. Bethune-Baker of varieties of A. corydon from Spain, Greece, 

 Syria, Asia Minor, and Pei'sia, and of A. thetis {bellargus) from Spain, 

 Algeria, and Greece ; by the Eev. George Wheeler, of examples from 

 Italy and Central Europe ; and by Miss M. E. Fountaine, of A. corydon 

 var. olyvipica, taken by herself at Amasia, Asia Minor, and of thetis 

 var. syriaca from the Lebanon. At the end of Mr. Tutt's remarks the 

 discussion was continued by Mr. A. L. Eayward, Mr. Hamilton H. 

 Druce, the Eev. G. Wheeler, Dr. T. A. Chapman, Mr. W. G. Sheldon, 

 Miss Fountaine, and other Fellows, the President paying a special 

 tribute to Mr. Tutt's lucid explanation and diagnosis of the various 

 forms of the two closely allied butterflies. — H. Eowland-Brown, 

 M.A., Hon. Secretary.
