 C. J. V. Gray, School House, Bradfield College, Berks ; R. C.

Mr. H. Moore exhibited a pair of the Long-tail ^i\k-moth, Ari/ema 

 moenas, Dbldy., from Assam, and called attention to the female, less 

 commonly seen, with tails not only long but broad and ribbon-like. 

 He also showed a fine aberration of Arctia caja which he was 

 presenting to the Society's collection. 



Mr. A. A. W. Buckstone exhibited the following series of Pt/rauieis 

 atalanta : (1) Bred from larvae taken wild at Wimbledon in October 

 last. The imagines emerged during November, the pupae having 

 been exposed to a warm but considerably fluctuating temperature. 

 The yellow at the apex of the forewings and on the outer-margin of 

 the hindwings was very much more pronounced than usual. The 

 apex of the wings and the outer margin of the underside of the 

 hindwings were also more conspicuously yellow. (2) For compari- 

 son a fair sample of a great many captured or bred under nomial 

 conditions. 



He also showed a considerable number of Ai/lais urticae, bred 

 from larvae taken at Merton in August last. The pupae were 

 subjected to the same increased but fluctuating temperature as were 

 those of P. atalanta. The imagines emerged in October and 

 November. In the majority of the specimens the yellow blotch 

 near the inner margin is diffused towards the hind and inner 

 margins, the yellow on the hindwing is also pronounced, and a 

 certain number of the examples have the veins of the hindwings of 

 this colour. 



Mr. Hy. J. Turner exhibited the following Rhopalocera from 

 California: Cdliaa behri, taken by Mr. G. B. Pearson, in the Yose- 

 mite country, at an elevation of 9,500 feet. This small but beauti- 

 ful Colias is an extremely local northern species, found at high 

 elevations in the Rocky Mts. Mr. Pearson writes, " We soon came 

 to Tuolumne Meadows (anglice-Twamley), and here we encountered 

 hundreds of (J. behri, flitting from flower to flower (low-lying plants). 

 Dr. Comstock, F.E.S., coming here later, found them by the 

 thousand."
