Mr. Jager exhibited the following species taken in South 

 Devon in August and September :— three Stilbia anoniala, 

 four LitJwsia caniola, five Nodna castanea, eight Laphygma 

 exigiia, one Epunda lichenea, one Leucanin albipuncta, one L. 

 vitellina, one Hcliothis arniigera, six L. piitrescens, and two 

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

 measuring 2\ inches in expanse. He remarked that d^iring 

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

 cold. 



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

 tenellmn, a female with abdomen bronze, and 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 Sym- 

 petrnm vnlgatuui. Mr. Lucas, however, said it was only the 

 common Sympctrum strwlatmn, 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 Lycaenids 

 from Japan with British examples of the same or allied 

 species for comparison : 



I. Chrysophanna phlceas. — This species exhibits very 

 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
