scaling, but with unusuall}- large, red, marginal spots; 

 female undersides with the red lunules bright, large, and 

 somewhat elongated, and a male in which they were small 

 and pale yellow ; also an underside aberration, of which the 

 following is a description : — ashy-gre}- at the base, fading to 

 pure white at the outer margins. Fore-wings, the upper of 

 the two basal spots indicated by a minute dot, the lower 

 absent ; the discoidal spot is distinct ; of the outer row of 

 spots (usually six) the four median are present, and are 

 slightly elongated towards the black sub-marginal crescents, 

 which are normal, and the red lunules bright and somewhat 

 contracted, leaving the white margins unusually broad ; 

 these are intersected by the strongly marked wing-rays, thus 

 giving the appearance of a marginal row of white quadrate 

 marks. Hind-wings : discoidals rather faintly marked, 

 the outer row of black spots very small, and the margins as 

 in fore- wings. Fringes of all wings pearly white. The 

 specimen is a female with slightly blue upper-side, and was 

 captured on August 7th, igio. 



He also showed a short series of hybrid Nyssia zonaria 

 male x Biston hirtaria female. The males are in size about 

 midway between that of the two species, and the markings 

 of each are well represented in the hybrids. The female is 

 interesting in that it shows an attempt to produce the two 

 forms of female, the almost apterous and the fully winged, 

 the result being a monstrosit}' with a ringed body like N. 

 zonaria, and four long, narrow, mis-shapen wings, hairy as 

 in N . zonaria, but very dark in colour, in that respect more 

 nearly resembling B. hirtaria. The specimens were reared 

 by Mr. J. W. H. Harrison in the spring of the present year. 



Mr. A. E. Tonge exhibited a fine series of Cosmotriche 

 potatoria, bred from larvae collected near Deal in 1910, 

 including some extremely dark, smoky, suffused specimens ; 

 a remarkable variety of Brenthis cnplirosyiic from Polegate, 

 igio, in which the ground colour was pale chocolate-brown 

 above and below ; a series of Boarmia rcpandata, including v. 

 conversaria, bred from New Forest larvae ; varieties of Agrotis 

 cxclamationis, from Southwold and Reigate, including speci- 

 mens in which the usual heart and dart markings were 

 replaced by a black blotch ; three of these were taken on 

 three successive evenings ; a series of photographs of eggs 

 of Lepidoptera enlarged 30 diams. 



Dr. T. A. Chapman exhibited a long series of examples of 

 Pararge egcria from Britain, Pyrenees Orientales, S.W. 

 France, N.W. Spain, and the Riviera, to show the range of
