Exhibitions, dc. 



Mr. Slater exhibited, on behalf of Mr. J. P. Mutch, — in 

 illustration of the effect of food in producing variation in 

 Lepidoptcra, — two specimens of Arctia caja, one of which 

 had been bred from a larva fed on lime-leaves, and the other 

 from a larva fed on the low plants constituting the ordinary 

 pabulum of the species. 



Mr. H.J. Elwes exhibited a large number of Lepidoptera- 

 Heterocera selected from those caught by him, with the 

 assistance of Mr. 0. Moller, in the verandah of the Club at 

 Darjeeling, in Sikkim, at an elevation of 7000 feet, on the 

 night of Aug. 4th, 1886, between 9 p.m. and 1 a.m. They 

 represented above 120 species, which is believed to be a larger 

 number than had been ever previously caught in one night. 

 Mr. Elwes stated that Mr. Wallace's observations on the 

 conditions most favourable for collecting moths in the tropics 

 were abundantly confirmed by his own experience during 

 four months' collecting in Sikkim and the Khasias. These 

 conditions are — a dark wet night in the rainy season ; a 

 situation commanding a large extent of virgin forest and 

 uncultivated ground ; and a white-washed verandah not too 

 high, with powerful lamps in it. At the Darjeeling Club he 

 lost many of the larger species which flew up to the top of 

 the verandah, where they were often caught by bats when 

 out of his reach. He said that on many nights during June 

 and July he took from sixty to eighty species, and during his
