mixed with other species of the genns. Hab. : Kent and Essex. Poecilochroma 

 pomedaxana, an apple feeder tintil now considered to be a variety of P. profun- 

 dana. Hah. : Devon and Herefordshire. Lipoptycha aeratana, for some time 

 represented only by a single specimen in his collection, but lately found in 

 Threlfall's series of Dicrorampha tanaceti. These have all been distinguished 

 through examination of the genitalia, and full descriptions are published in the 

 Ent. Mo. Mag. for January, 1915. Mr. W. A. Tyerman showed a fine series of 

 Sphinx ligustri, most of which had laid over until the second year after pupation ; 

 a fine and long series of Meianippe galiata from Ainsdale (the ova were deposited 

 in September by a very late female) ; also from Ainsdale, Acronycta leporina, 

 Cucullia chamomillae and Ghariclea umbra. By Mr. Wm. Webster, a large 

 species of Cicada from India. 



Meeting held at the Royal Iiistitxxtion, Colquitt Street, Liverpool, Monday, 

 Ja7iuary IHth, 1915. — Dr. J. Cotton, Vice-President, in tlie Chair. 



Mr. W. Mansbridge read a paper entitled " Silverdale as a Collecting 

 Ground." Having given a brief survey of the geology and flora of the district, 

 the aiithor enumerated a large number of local species of Lepidoptera, generally 

 rare in the North of England, biit which had been recorded from this favoured 

 area. Manj' of these, however, had not been reported for a couple of decades 

 or longer, and members were urged to endeavour to confirm such records as 

 L. corydon, T. betulae, P. aegeria, E. hyperanthus, L. minima, S. malvae, S. anomala, 

 A. marginepunctata, L. olivata, and E. taeniata, all of which had been recorded 

 some thirty years ago. He also referred to the two field meetings which had 

 been held at Silverdale ; gatherings which had been greatly enjoyed by all those 

 who had attended. The author mentioned having taken a fine specimen of 

 Coccyx cosmophorana on May 30th, 1914, in Gatebarrow wood, also Adela fibulella 

 and Eupithecia constrictata. 



Mr. A. W, Hughes exhibited Lepidoptera from Eastham as follows: — 

 Hybernia defoliaria, H. aurantiaria, and a very long series of Cheimatobia 

 brumata showing great variation from very pale to very dark brown, almost 

 chocolate-coloured forms ; the latter were scarce, forming only three per cent, 

 of the number captured. H. aurantiaria had not been recorded previously for the 

 locality. Mr. F. N. Pierce showed his extensive series of the genus Cnephasia 

 (Sciaphila), containing all the British species except wahlbomiana and abrasana. 

 With regard to these he stated that it was considered very doubtful whether 

 they had any right to be included in the British fauna, or even to be ranked as 

 good species at all. The variation was remarkable in that almost every species 

 showed melanism and albinism, and it is only by a microscopic examination of 

 the genitalia, which can easily be made without damaging the specimen, that 

 the moth can be identified, especially when it approaches the extreme variation.
