Mr. Jager exhibited the following species taken in South 

 Devon in August and September : — three Stilbia anomala, 

 four Lithosia caniola, five Noctua castanea, eight Laphygma 

 exigua, one Epunda lichenea, one Leucania albipunda, one L. 

 vitellina, one Heliothis armigera, six L. ptitrescens, and two 

 Colias editsa var. helice, one of which was a large specimen 

 measuring 2j inches in expanse. He remarked that during 

 his stay the days were mostly fine, but that the nights were 

 cold. 



Mr. W. J. Lucas exhibited a typical c? and ? Pyrrhosoma 

 teneUum, a female with abdomen bronze, arid another with 

 abdomen crimson except circlets at the junctions of the 

 segments which were black ; also a nymph-case which pro- 

 duced a normal male, and another which produced a bronze 

 female. All varieties were from the New Forest. Mr. A. H. 

 Hamm had taken bronze varieties at two places in Devon- 

 shire. The bronze ? nymph-case was darker than the other, 

 but probably only by chance. 



Mr. Jager exhibited specimens of a dragon fly he had seen 

 in South Devon and which it was thought might be Syni- 

 petrum vulgatum. Mr. Lucas, however, said it was only the 

 common Sympetrum striolahun, and stated that the former 

 could be distinguished by the absence of a brown band 

 between the second and third black stripes on the sides of 

 the thorax, the absence of yellow dots on the abdomen, the 

 presence of a longitudinal black line on each side of the first 

 three abdominal segments, the very prominent vulvar scale, 

 the generally more olive colour, the black line in front of 

 the vertex being produced along the side of the eyes, and by 

 diflerences in the structure of the male genital organs. 



Mr. Kaye exhibited series of several species of Lycasnids 

 from Japan with British examples of the same or allied 

 species for comparison : 



I. Chrysophanus phlcBas. — This species exhibits ver}' 

 markedly the influence of temperature. In Japan the bright 

 copper form occurs in the spring, while the darker forms 

 (cf. var. eleiis of South Europe) occur in the late summer. The 

 latter generally have the coppery band of the hind wings 

 unchanged. The spring brood in both countries are practi- 

 cally indistinguishable on the upper side, but on the under 

 side of the fore-wings of the Japanese specimens the white 

 rings round the spots are more pronounced, and the blotches 

 on the hind margins are five or six in number instead of 

 three, as in the British examples. On the undersides of the 

 hind wings the ground colour is of a silvery brown and the
