the distal extremities of the claspers are quite free and widely separated, 

 Group III (The Morsitans Group). This group comprises G. morsitans, West- 

 wood, G. suhniorsitans, Newst., and G. longipalpis, |Wiedemann. In these the 

 claspers are completely united by a spinose membrane and they are also fused 

 medially. They are of a very remarkable form, their shape somewliat I'esem- 

 bling the scapula of a mammal in miniature, and are altog-ether much more 

 highly complicated structures than those in either of the preceding groups. 

 Thus we see in these three groiips forms which are so widely different as to 

 lead one to assume, without taking other external features into consideration, 

 that they represent three distinct genera. Certain it is that these insects 

 illustrate one fundamental principle of evolution, namely, that they have 

 attained great development of one set of morphological characters, and have 

 retained others apparently of an ancestral type. — H. E. Sweeting and Wm.

Entomological Society of London : Wednesday, December 7th, 1910. — 

 Mr. H. Eowland-Brown, M.A., Vice-President in the Chair.

Tlie Vice-President announced that he had received from Dr. A. Fenyes, 

 F.E.S., of California, and exhibited in his behalf four boxes containing an 

 admirable collection of North American Aleocharine Coleoptera, which the 

 donor had offered most kindly to the Society. In the absence of any collections 

 belonging exclusively to the Entomological Society of London, however, he had 

 asked Dr. Fenyes to authorize a transfer of the gift to the British Museum 

 (Natural History), and he therefore, with the consent of the meeting, handed 

 it over to Mr. G. J. Arrow for that purpose. 



Mr. H. W. Andrews exhibited a short series of Carphotricha guttularis, 

 Mg., a scarce Trypetid, taken at Milford Haven in July last, and a specimen of 

 a unicolorous form of Prosena sybarita, F., from North Kent, Jiily 30th, 1910. 

 Commander J. J. Walker, specimens of Syagrius intrudens, Wat., an Australian

 of the captor, Mr. Joseph Collins, of the Oxford University Museum, Conops 

 signata, Wiedemann, <? and ? , a Dipteron new to Britain, taken at Tubney, 

 Berks., September 11th, 1910. Mr. E. C. Bedwell, examples of Bruchus pectini- 

 eornis, L., a beetle usually looked upon as introduced into this country in 

 granaries, but in this case swept on an open hillside at Chipstead, Surrey ;
