It was noticed that many of these Reigate specimens have 

 dark spots immediately within the outer marginal border of the 

 forewings, but which do not form part of this border, as they appear 

 to do when viewed by the naked eye ; for when examined under a 

 lens they are found to be composed of scales similar to those which 

 form the black blotches on the costa, and differ distinctly from the 

 metallic brown scales of the marginal border. 



Mr. Buckstone also exhibited drawings by the Rev. C. R. N. 

 Burrows of the genitalia of the dwarf race of Agriades coridon, and 

 of the larger race found at the base of the Downs upon which the 

 former race occurs, and read the following note received regarding- 

 them : — 



" I have examined your coridon, and enclose drawings thereof, to 

 which I have added a drawing, all exactly the same scale, of the 

 ordinary J coridon of the Kentish hills. (See " Ent. Rec," 1919, 

 pi. iv., p. 89.) 



" You will at once recognise the difference in size. To me it is a 

 revelation. I thought I had heard that whatever the size of the 

 imago, the genital organs were always the same size. It is, it 

 appears, not so by any manner of means. 



" I have added in figures the nearest measurement I can arrive 

 at of the butterflies themselves. You see the hill-top race is just 

 over half the size of the normal insect. It appears to be much the 

 same with the genitalia. 



" Of course, the drawings are but rough, but I think they are 

 worth publication, accompanied by photos of the butterflies them- 

 selves. There is just the possibility that you have dropped upon a 

 different species, as yet unknown, but I do not think the genitalia 

 support this idea, nor does there appear to be a Pal^arctic species 

 other than coridon." (See "Ent. Rec," 1919, p. 89, pi. iv.) 



Mr. Bunnett exhibited details of the life-history of Coleophora 

 nigricdla, and read a short paper on the mode of progression of the 

 larva bearing its case. He showed photographs of the " tracks "' 

 made by the larva on a glass microscopic slide. (See page 32.) 



FEBRUARY 27th, 1919. 



Mr. Bowman exhibited a specimen of the black form of Hibernia 

 leucopluearia in which the fringes were conspicuously white. It 

 was taken in Epping Forest in 1909. 



Mr. Hy. J. Turner exhibited a series of Ca»iptograt)viia hilineata 

 from the Island of Cyprus, including the form ab. testaceolata^
