SEPTEMBER i^ih, 1900. 



Mr. W. J. Lucas, F.E.S., President, in the Chair. 



Mr. F. Noad Clark exhibited a specimen of Locusta 

 viridissima, taken at Deal. 



Mr. South exhibited a series of Zygcena trifolii, bred from 

 cocoons taken in a marshy place near Oxshott. They were 

 found both well up the stems of grasses, as well as close to 

 the earth. About half the number taken emerged, and the 

 rest were either attacked by parasites or were attempting to 

 lie over. The specimens were by no means large in size. 

 The variation showed the same range as in a series he had 

 obtained from a meadow at Northwood, in Middlesex. Mr. 

 Lucas had noticed among those obtained by himself from the 

 same locality that the females had a much greater tendency 

 to confluence of spots than the males. 



Mr. Lucas exhibited several specimens of Thamnotrizon 

 cinereus, an Orthopteron which he had taken in the New 

 Forest. 



Mr. Colthrup exhibited a short series of Lasiocampa 

 (Bombyx) quercus from Margate. 



Mr. Kemp exhibited a specimen of Aplecta occulta, taken 

 at sugar near Cromer. It was remarked that it was an 

 unusual occurrence for this species to be taken so far south. 

 It had been, however, taken some years ago in Tilgate 

 Forest. [It has since been reported by Mr. Porritt from 

 South Devon.] 



Mr. Turner exhibited series of the following Coleoptera
