the usual pink areas of the wings were extremely pale, almost 

 white. 



Mr. Hy. J. Turner exhibited an aberration of jSIelitaa dulyum,. 

 taken at Zermatt, in which the greater number of the black 

 markings on all the wings were of a very faint slate colour ; also 

 a number of females including one of extremely dark ground 

 colour from the Sarnthal, Tyrol. 



Mr. Frohawk exhibited some unusually large specimens of 

 Lompides hceticHs which he had bred from ova, the larvae having 

 been fed on green peas. The white on the under-surface was also 

 very well accentuated. 



Mr. Frohawk also exhibited a semi-albino example of the 

 woodcock {Srolopa.v rusticnla) sent to him from Ireland, and said 

 that the plumage of male and female specimens was absolutely 

 identical. He then showed a drawing of an albino specimen 

 of the great snipe {Galinario major) from Cambridge, and several 

 very clever pencil sketches of protective resting habits of lepidoptera. 



Mr. R. South exhibited long series of five successive generations 

 of Acidalia riif/idayia, Hiib., originating from ova laid by a female 

 captured at Bishop Auckland on August 7th, 1910, and com- 

 municated the following details : — 



" The ova were deposited on August 8th, 1910, and hatched 

 on August 15th. The larvae fed readily on knot-grass, but 

 during the winter they were supplied with dandelion, and in the 

 spring they were fed up on the same plant. 



"1st generation. — 26 moths were bred during May and June, 

 1911. On June 4th and June 9th ova were laid. The larvae 

 produced were fed up on dandelion. 



" 2nd generation. — Over 60 moths were reared in July and 

 August, 1911, and were of the small summer form. On July 29th 

 ova were deposited, which hatched on August 6th. Again 

 dandelion was selected as the food. 



"3rd generation.^ — ^About 30 moths were reared during September 

 and October, mostly of the small summer form, but the seven 

 moths last to emerge were of the large Spring form. Many larvae 

 of this brood hibernated, and after feeding up in the early spring 

 the moths appeared in April and May, 1912, all of the spring 

 form. 



" 4th generation. — The larvae, which hatched from the ova 

 deposited by the moths which emerged in September, hibernated 

 quite small, and were fed up by May 30th, 1912. On June 12th.
