(Gastropacha) quercifolia, showing very clearly the remarkable 

 dark and light banding. 



Mr. Carpenter wished to record the unusual occurrence of 

 a species of butterfly copulating in captivity. He said that 

 Mr. Joye had a brood of larvae from a bred pair of Pararge 

 egeria, which he had enclosed together in a bandbox covered 

 with leno, and exposed to the full sun. It was noted that, 

 with the exception of Mr. Bateson's experiment with Pie/is 

 napi and v. bryonicc, most of the records of such pairings 

 contained an element of doubt. 



SEPTEMBER 2\th, 1903. 



The President in the Chair. 



Mr. South exhibited (i) a short series of Aplccta nebnlosa, 

 reared from larvae received from Mr. Thompson, of Chester, 

 who collected them in Delamere Forest in the spring of 

 1903. All the moths bred were darker than the typical form 

 of the species, but only two of var. robsoni, Collins, appeared. 



(2) Series of Cabcra pusavia, bred from larva obtained in 

 September, 1902, from Oxshott and Wisley in Surrey, and 

 from Epping Thicks, Essex. All the larva; were beaten 

 from birch, and as most of them appeared to be nearly full 

 grown, they were allowed to pupate in the cages, to which 

 they were transferred without any supply of food beyond 

 that placed with them when collected. 



From the result it would seem that some of the larvae did 

 not obtain sufficient nourishment, and as a consequence 

 produced undersized imagines. In the aberrant character 

 of the markings these small examples resemble rotundaria, 

 but in the shape of the wings they do not differ much from 

 the larger specimens with typical markings. 



Mr. F. B. Carr exhibited (i) specimens of a brood of 

 Malacosoma nciistria, bred from ova found on sallow in the 

 New Forest. All the specimens were of the same dull 

 brown shade, and none of the red tint, which he believed to 

 be the normal colour. About half of the males were pale, 

 and half were of the same shade as the females. 



(2) A larva of Cleoni glabraria, which was taken in the 

 New Forest at Easter and was still feeding. 



Mr. Boxer exhibited a collection of butterflies and moths 

 from Durban, collected by Mr. W. T. Temple. 



Mr. West (Greenwich) exhibited short series of three
