THE SOUTH LONDON ENTOMOLOGICAL AND NATUEAL 

 HISTOEY SOCIETY'S EXHIBITION. 



By Hy. J. TuRNEB, F.E.S. 



An Exhibition of this Society was held on the evening of 

 Saturday, March 10th, at their rooms in Hibernia Chambers, 

 London Bridge. Although the Society still continues to hold a 

 special exhibition of varieties each year, some years have elapsed 

 since it had organized so extensive and so representative an 

 assemblage of natural history objects as were placed together 

 on this occasion. In spite of the weather, a large number of 

 members and their friends were present, and the choice, varied, 

 and beautiful objects — which had been tastefully arranged by 

 the Committee and a willing band of helpers — were much 

 appreciated. 



In the British section Mr. E. Adkin exhibited (1), a long series of 

 Aglais (^Vanessa) xirtica, arranged to show the direction of the minor 

 variation; (2), a collection of the Nycteolidse and Nolid^e, including 

 fine dark forms of most of the species ; (3), the Anthrocerid® 

 (ZygaBnidfe), with yellow A. trifolii and forms of A. filipendulm, 

 grading in colom' from rich red through shades of terra-cotta to pale 

 yellow ; (4), specimen of Mesoyona acetosellce, from Polegate, 1895, and 

 a long and varied series of Tcoiiocampa gothica and T. incerta from its 

 main localities ; (5), series of Selenia lunaria and S. tetrahinaria, with 

 hybrid S. hilunaria X S. tetralunaria ; and (6), Abraxas grossulariata of 

 many forms, including ab. vadeyata. Mr. B. W. Adkin exhibited (1), 

 local races, varieties, and aberrations of C'osmotriche potaturia, including 

 males with female coloration, and vice versa; (2), ditto of Lasiocampa 

 g-Mercus and Paclujcjastria trifolii; (3), a large number of aberrations, 

 of which a specimen of Cosmia trapezina — very pale, with almost 

 black transverse band — was particularly notable. Mr. A. W. Bacot 

 (1), the series of hybrids obtained by him from Malacosoma neustria 

 and M. castrensis ; (2), various races of L. quercus, with the results of 

 crossings between the races ; and (3), a considerable portion of the 

 progeny obtained from a pairing between Awphidasys betularia male 

 and var. doubledayaria female, illustrative of the fact that the brood 

 were of the two distinct forms, only one specimen being in any way 

 intermediate in marking. Mr. F. E. Bellamy (1), a black form, var. 

 obscura (?), of Anthrocera [Zyytsna) trifolii, from Eingwood, 1899 ; (2), var. 

 fowleri, of Polyommatas corydon, from Swanage ; and (3), ab. lutea of 

 Calliinorpha dominula. Mr. W. Brooks a number of very large, varied, 

 and beautiful forms of Manduca atropos, the selection of many years' 

 breeding from Lincolnshire pupae, and also specimens of the curious 

 air bladders which are found in the body of every imago. In one case 

 only had he found two bladders in one imago (shown). Mr. W. E. 

 Butler (1), summer and autumn broods of Stauropus fagi, some 

 extremely dark ; (2), a beautiful series of Tiliacea {Xanthia) aurago, 

 the extreme red forms being particularly notable, one with almost a
