DECEMBER nth, 1902. 



Mr. F. NoAD Clark, President, in the Chair. 



Mr. Cowham, of Stoke Newington, N., was elected a 

 member. 



Mr. South exhibited on behalf of Mr. J. Arkle, of Chester, 

 some varieties and aberrations of Lepidoptera, amongst which 

 were a series of Cccnonympha typhon, var. rothliebi, a black 

 suffused male specimen of Agrotis exclamationis, a very dark 

 form of Cymaiophora duplavis, and a pretty form of Euiatuvga 

 atomaria, in which the outer line on all the wings was replaced 

 by a broad black band. 



The specimens of rothliebi, which were from Delamere 

 Forest, showed considerable variation in size, number, and 

 shape of the ocelli on both surfaces, and also in the amount 

 of white markings on the underside of the hind wings. In 

 two examples the ocelli were more or less oval in shape, with 

 the outer edge produced. In another specimen the ocelli on 

 the undersides of the hind wings were larger than usual, 

 especially as regards the two nearest the anal angle, and the 

 white markings on these wings were well defined. The 

 white markings of a fourth specimen were unusually well 

 developed, and consisted of a broad, irregular-edged, trans- 

 verse band, reduced to a slender line between veins two 

 and four, an elongate patch at the base below the costa, 

 and a curved and tapered streak beneath the discoidal 

 cell extending to the band. 



Mr. Ashdown exhibited specimens of the Homopteron 

 Ledra aiirita, taken at Mickleham in October, 1902, together 

 with larvae of the same species from the New Forest. Mr. 

 Turner said that the species was to be found at Chattenden 

 Woods, Kent, and Mr. West had obtained it at West 

 Wickham. 



Mr. R. Adkin exhibited a specimen of Enchloc cardamines, 

 in which the usually large discoidal spot on the fore-wings 

 was reduced to a mere speck. 



Mr. Goulton exhibited a specimen of Catocala nupta taken 

 at Balham, showing a general darkening of the colour. Mr. 

 Carpenter thought this was unusual, and referred to the 

 species as being of an exceptionally stable character. Mr. 

 Turner had noted other dark examples in the neighbourhood 

 of London.
