Mr. G. H. Verrall, President, in the Chair.

 Fellows of the Society. 



E.fli ibitions. 



Mr. H. AV. Andrews exhibited Atherix crassipes, Mg., a 

 Dipteron new to the British list, taken near Ticehurst, Sussex. 

 Mr, Verrall remarked that the species was but little known on 

 the Continent, and quite unexpected in England. Originally- 

 described in 1820, there was no record of its re-occurrence 

 until 1864, and there have been only one or two slight refer- 

 ences to it since. He added that it was a most distinct species, 

 and, like Leptis, was addicted to settling upon the leaves of 

 alder. 



Col. Yerbury exhibited (a) Anthrax 2)C('nisctos, bred from a 

 lepidopterous pupa found in sand at St. Helen's, Isle of 

 Wight, by Mr. Holland, Hope Museum, Oxford. Pupa found 

 7th July, 1899, fly emerged 12th of the same month. Schiner 

 records Anthrax as being parasitic in the larvje and pup;e of 

 Lepidoptera and Hymenoptera. Dr. Sharp states that M. 

 Kiinckel d'Hei'culais bred Anthrax fen est rails {yenestratal) 

 from the egg-case of a large locust, Ocnerodes, sp. He also 

 exhibited (b) Tahanus hromms — pupa found as above, emerged 

 12th July, 1899, observing that Tahanus is generally sup- 

 posed to breed in wet mud round the margin of pools — and 

 (c) a new species of C ordyhaxi, of which live males and five 

 females were taken at Aviemore in July 1899, and further 

 specimens again in abundance in the same place June 1900. 

 Col. Yerbury mentioned also that he had sent some of them
