heights we spent half an hour at one of the little streams which run down the 

 mountains into the Dee, and here, under pebbles, we took BemUdium decorum, B. 

 tihiale, B. atrocceruleum, and B. prasinum. 



A walk of about an hour brought us to the foot of Moel-y-Gramelin, on the 

 slopes of which we worked for some time. Insects were, however, very scarce, the 

 only species worth noting being Carahus arvensis, C. catenulaius, Pterostichus 

 vitreus, and a single specimen of Miscodera arctica, which fell to ray lot. As the 

 latter species was among our desiderata, we searched carefully for more, but without 

 success. A critical examination of every Pterosticlms madidiis and Jsehria hrevi- 

 colUs failed to give us P. cethiops or N. Gyllenhalii, although I think it is a likely 

 spot for both. 



These high moors are frequently mentioned in Dawson's " G-eodephaga Britan- 

 nica," and I think they would well repay systematic working at all times of the 

 year. Many of our rare Aphodii no doubt occur there, and, in fact, I know that 

 A. Zenkeri was taken there in September, 1883.— E. Wilding-, 40, Downing Street,

 F.R.S., President, in the Chair. 



Messrs. Ernest Sable, of Grrove Road, Clapham Park, and H. C. Dent, of 20, 

 Thurlow Square, were elected Members. 



Mr. R. M. Christy (present as a visitor) exhibited a drawing of the larva of the 

 local form of Platysamia Columbia, known as NoTcomis : he had found the larva in 

 Canada feeding on Elceagnus argentea, the peculiar silvery appearance of which 

 was strikingly in accord with the colour of the larva, which latter was probably pro- 

 tected thereby. He also showed faded leaves of ^e^wZa ^ZawcZwZo^a, and said he 

 had observed Papilio Asterias settle on similar patches of leaves, apparently mis- 

 taking them for flowers on account of the bright colouring. Mr. Weir said he had 

 observed white butterflies settle on patches of variegated leaves in his own garden, 

 and he alluded to the well-known case of bees coming to ai'tificial flowers on a lady's 

 bonnet. 



Mr. Billups exhibited two species of Pezomachiis new to Britain, viz., P. imma- 

 turus and vulnerens, taken at Headley Lane in January, and remarked that on the 

 same day he took thirteen species of the genus. 



Mr. E. A. Fitch exhibited a rather large moth, apparently belonging to the 

 CramhidcB, found at rest on a wall in Dr. Wallace's garden in Colchester, having 

 probably been imported in plants. It was not contained in the National Collection, 

 and was perhaps undescribed. 



Mr. Dunning called attention to a paper by Mr. F, Gr. Heathcote, published in 

 the Transactions of the Cambridge Philosophical Society, on a curious pouch-like 

 organ at the base of the mandibles in Scutigera {Myriopoda), the function of which 

 was considered to be auditory.
