on the continent of Europe, said that while England was the home of 

 many dark races, e. g. Polia chi var. oUvacea, Amphidasi/s bctnlaria var. 

 doublcdayaria, the dark forms of H. abrnptaria, &c., it was all the more 

 curious that in the twenty-two species of Nocture enumerated the ten- 

 dency was always for the British form to be lighter and the continental 

 darker. — Dr. F. A. Dixey exhibited specimens of Ixiasbaliensis, Friihst, 

 and Hjipliina nerissa, Fabr., from the island of Bali, Malay Archipelago. 

 He said that in this instance the liupldna had, on the whole, acted as 

 the model, under whose influence the Ixias had drifted some distance 

 away ffom the usual aspect of its genus ; but in the particular case of 

 the hind wing the process was reversed, the Ixiasi having been the 

 model, and in its turn mimicked by the Huphina. If his conclusions 

 generally were well founded, the associations between the two must 

 necessarily be Miillerian and not Batesian. — Mr. S. A. Neave exhibited 

 a number of Lepidoptera selected from the collection made by him in 

 North-east Rhodesia in 1904 and 1905, comprising the following rare 

 species : — Melanitis libija, Distant ; Leptena homeyeri, Dewitz ; Pentila 

 peucetia, Hew. ; Catochrysops gifjantea, Trim. ; Crenis pechiieli, Dewitz, 

 and C. rosa, Hew., which are evidently two distinct species ; and 

 Crenidomimas concordia, Hopff., the mimic of the last two species. 

 Also two notable species of the genus ApJmmis — including the female, 

 so rarely taken in this genus — Acraa tiatalica, Boisd., and A. ane- 

 vwsa, Hew., with two remarkable moths showing a close mimetic 

 resemblance to them. The exhibitor further stated that his collection 

 should prove interesting as regards seasonal forms, especially in the 

 Acrffiin^ and Pierinse, of which he showed additional examples. He 

 suggested that the brilliant dry season phases of A. indxina, Trim., had 

 been evolved, by stress of circumstance at that time of year, from a 

 duller coloured phase, such as, in this region, we still find in the wet 

 season, when the struggle is not so keen. — A discussion of seasonal 

 forms in these species followed, in which the President, Prof. E. B. 

 Poulton, Dr. F. A. Dixey, Mr. G. A. K. Marshall, and other Fellows 

 joined. — H. Rowland-Brown, M.A., Hon. Secretary. 



The South London Entomological and Natural History Society. 

 —October llth, 1906. — Mr. Robert Adkin, F.E.S., President, in the 

 chair. — Mr. Kaye exhibited a specimen of the extremely rare Thyrid, 

 Draconia rusina, from Trinidad, resembling an irregularly injured leaf, 

 the surface of which had been eaten by larvae. — Mr. Sich, the pupre of 

 Pieris daplidice, and a photograph of the larva by Mr. Tonge ; they 

 were from Geneva ova. — Mr. Step, a larva, probably of Prodenia 

 littoralis, found feeding inside the skin of a banana. — Mr. Jager (1) 

 fine series of dark green and light yellow forms of Bn/ophila miiralh, 

 from Starcross ; (2) Heliotlns peltigera, bred from South Devon larvae; 

 (3) Ayrutis vestigiaUs, with unusually clear white markings, taken at 

 sugar at Starcross ; with (4) specimens of Laphygma exigua. — Mr. R. 

 Adkin, a series of Peronea pennutana, reared from larvffi feeding in 

 Rosa spinosissima , from Wallasey. — Mr. South (1) nearly full-grown 

 larvae of L. exigua, feeding on plantain, dandelion, and groundsel; 

 they were from ova deposited by a female taken at Kingston by Mr. 

 Richards; {2) Euchlo'e cardaminc:^, from larvae fed on wallflower; for 

 Mr. Hay ward (3) a Caber a pusaria, leaden grey in colour, and the
