taken in Kent, which had the pebble marking much suffused, 

 and the ground-colour darker than the types. 



Mr. O. E. Janson exhibited a living specimen of Acridium 

 eegyptium, L., found in a cauliflower in Bloomsbury, and 

 probably imported from Italy. Professor Poulton said he 

 had also received similar examples introduced in the same 

 way. 



Mr. G. C. Champion exhibited two examples of Malachius 

 barnevillei, Puton, captured by Mr. Thouless at Hunstanton, 

 Norfolk, in June 1899, a recent addition to the British List. 



Mr. H. W. Andrews exhibited a $ and $ of Machimus 

 msticus, Mg., a rare Asilid, taken in cop. at Freshwater, Isle 

 of Wight, on August 13th, 1903. 



Mr. W. J. Lucas exhibited a $ Panorpa cognata taken 

 at Byfleet Canal on August 23rd, 1904. The species occurs 

 at Folkestone, and is said to be found in the New Forest. 

 It is a little difficult at times to identify the $ alone, but 

 Mr. K. J. Morton also had determined the insect in question 

 to be P. cognata. For comparison he brought also $ 

 specimens of P. communis and P. germanica. 



Papers. 



Mr. T. Gilbert Smith read a paper entitled " A revision of 

 the genus Criocephalus, with notes on the habits of Asemum 

 striatum and Criocephalus ferns," by himself and Dr. D. 

 Sharp, M.A., F.R.S., and exhibited specimens to illustrate his 

 remarks. 



A discussion followed in which Mi-. Donisthorpe remarked 

 that he had bred Criocephalus polonicus, and Mr. A. J. Chitty, 

 commenting on the life history of these beetles, said that he 

 thought the longevity of some Coleopterous insects had hardly 

 been appreciated. He possessed a Dytiscus still alive which 

 he had taken in October 1902, while Mr. Donisthorpe 

 mentioned the case of a Longicorn bred by Mr. C. O.

 Walker,, Mr. G. C. Champion, and other Fellows continued 

 the discussion. 



Papers were also read by Dr. T. A. Chapman, M.D., F.Z.S.,
