Mr. McArthur exhibited a specimen of Agrotis segetum, 

 having a narrow, very dark marginal band on each of the 

 hind wings. The white ground colour and the light fringe 

 made the band very conspicuous. It was captured on the 

 South Downs, near Brighton, in June, igoi. 



Mr. Edwards exhibited a very large and unusually perfect 

 nest of Vespa vulgaris. It was obtained near Rochester in a 

 hollow tree during the past season. 



Dr. Chapman exhibited imagines of Crinoptevyx faniilicUa, 

 de Peyer, bred last summer ; and living lar\-ai bred out of 

 doors at Reigate from eggs laid by some of the moths. The 

 larvae, he remarked, are at first miners, but after cutting out 

 their cases they live precisely like Coleophorai, instead of 

 grubbing about on the ground, as nearly all the other lower 

 Adelidas {Incurvaria, etc.) do. He also stated that there was 

 neither in the neuration, nor in any other item of structure or 

 habit, anything he could find to confirm Spuler's opinion 

 that it was intermediate between the Palaso- and Neo-Lepi- 

 doptera. The position was rather above but not near to 

 Incurvaria, one of the lowest genera of Adelidae {Tinea 

 aciilcata, Spuler). 



Mr. R. Adkin exhibited a long series of Acidalia inargini- 

 piinctata {pvomutata) , the result of several broods, and read a 

 paper entitled "A Life-cycle of Acidalia inarginipunctata " 

 (see page 3)- . 



In the discussion which followed Dr. Chapman remarked 

 that it was a most unusual thing for some larvae of a summer 

 brood to go over to help form the autumn brood, and he also 

 noted the extraordinary fact of the insect gaining protection 

 at certain times only from its resemblance to patches of dust 

 occasionally in abundance on ivy leaves near its habitat. 

 Mr. Montgomery referred to the mixed character of the 

 genus Acidalia, one section having keeled larvae and the moths 

 scattered their eggs, while the other section had cylindrical 

 larvae and the moths laid their eggs in batches.
