examined numerous specimens of P. cardui in the spring, 

 and they were invariably females in which the ova were 

 undeveloped ; and he suggested they were infertile, and that 

 had they been paired they would not have immigrated to 

 this country. Dr. Chapman called special attention to the 

 immigration of P. rapce, which phenomenon he said it was 

 rarely the good fortune of an entomologist to observe. 

 Mr. Buckstone had taken P. cardui at Sevenoaks in the 

 spring, and all, some eight specimens, were females. 



DECEMBER 14th, 1899. 



Ur. Chapman, F.L.S., Vice-President, in the Chair. 



Mr. Robson exhibited a bred series of Dianthacia irregu- 

 laris from Tuddenham, all the specimens being unusually 

 large. 



Major Ficklin exhibited a specimen of D. lutcago, var. 

 ficklini, which he stated he would be pleased to place in the 

 Society's cabinet. 



Mr. Lucas exhibited a specimen of Somatochlora inctallica 

 and contributed the following note : 



" As many of you know, Mr. C. A. Briggs, accompanied by 

 Mr. King, of Glasgow, passed a fortnight last July in the 

 North of Inverness, in search of some of the northern dragon- 

 flies, including Somatochlora inctallica, which as far as is 

 known occurs in the British Isles in one district only in 

 that county. They were successful in their search, and Mr. 

 Briggs has sent me a well-set specimen of inctallica, in good 

 condition, for the Society's cabinet. I might add that apart 

 from its beauty, its scarcity and the difficulty attending its 

 capture give it considerable interest and value." 



Mr. Robert Adkin exhibited examples of a Crambus taken 

 in his garden at Lewisham, between August 16th and 28th 

 last. He said that he now had no hesitation in referring 

 them to Crambus geniculeus, but that the appearance of the 

 specimens was so much less robust than, and the markings 

 so faintly indicated when compared with, South Coast exam- 

 ples of that species, that he at first had some hesitation in 

 assigning a name to them. 



Mr. Edwards exhibited long series of most of the follow- 

 ing species of Erebia, taken by himself in July, .1899, in the 

 neighbourhood of Fusio, the Simplon and Macunagno : 



E. ceto, E. lappona, E. goante, E. tyndarus, E. euryalc,
