coloration, when at rest in a chink of the bark of an oak, 

 together with the portion of the bark of the tree with the 

 insect placed in situ just as when the photograph was taken. 

 He also showed the photograph of a $ specimen of Phigalia 

 pcdaria (pilosaria), which was very conspicuous in the posi- 

 tion of rest it had selected. 



Mr. R. Adkin exhibited a series of Hadena protect from 

 Rannoch, together with a series from the south of England 

 for comparison. The general tone of colour of the Rannoch 

 specimens was much less green than the southern examples, 

 and they presented a much brighter appearance, the contrast 

 between the light and dark markings being very sharply 

 defined. 



Mr. Henry J. Turner exhibited a series of Parargc mcera, 

 showing the direction of variation in this widely spread 

 species, and read the following note : 



"This species is closely related to our British P. megccra, 

 and is abundant in many parts of Central and Southern 

 Europe. The wings are dark brown with a submarginal 

 band of more or less large tawny patches, an apical white 

 dotted black spot on the fore wings, and a series of similar 

 spots in the tawny patches of the hind wings. This is the 

 typical form. The variation is as follows : 



"a. Sexual. — The $ has a broad velvety patch of andro- 

 conial scales extending from the centre of the inner margin 

 of the fore wings in the direction of the apex. 



li b. Diminution of fulvous patches = ab. obscura, in which 

 only narrow fulvous rings remain around the eye-spots of the 

 upper surface ; and ab. monotonia, a S form with scarcely 

 any trace of the fulvous colour. 



" c. Increase of the fulvous areas = var. et ab. adrasta, in 

 which most of the fore wing is more or less deeply suffused 

 with fulvous, often of two shades, being much lighter around 

 the apical eye-spot. 



" d. Number of eye-spots on the upper side of hind wings. — 

 These vary from two to four, more or less well developed, 

 and occasionally the commencement of a fifth. 



" e. Variation in the apical spot. — Of this there exist four 

 stages — (i) a large spot with one white pupil ; (2) with a 

 second white pupil in the apical spot, which is elongated 

 downwards ; (3) with a well defined small pupil above the 

 bi-pupillate apical spot ; (4) with an additional well developed 

 eye-spot beneath the bi-pupillate apical one. This last form 

 has been named ab. triops. 



" I should like to draw attention to the very extreme forms
