beauties of Mr. Sydney Webb's selection of insects, which he 

 (Mr. Webb) had most thoughtfully arranged with infinite pains, 

 consisting of the following : six species where the males differed 

 exceedingly from the females ; four species, in two of which there- 

 were two forms of the females, and two with two forms of males ; 

 nine species in which either the male took on the female, or the 

 female took on the male plumage ; four species representing seasonal 

 varieties ; six species showing the differences in the insect of the 

 north, west, and south of England, the Shetland hills, and also 

 four sets of varieties of the annulet, illustrative of the change of 

 colour in limestone, sandstone, peaty, and chalky districts ; six 

 species showing absence of colour pigment, and six species showing 

 excess of pigment ; eleven species with a tendency to obscuration 

 by dark scales and smokiness ; ten species in which the red' 

 coloured markings have been either mixed with or converted inta 

 yellow, greens converted into orange, and white saturated with 

 yellow; six species where the markings have been suppressed or 

 run into one another ; a series of five specimens of the peacock 

 butterfly, demonstrating the gradual diminution of the eye-like 

 spots, and final extinction of these on the lower wing : a long 

 series of the ringlet, exlnbiting on the under side enlargement of 

 the rmg-liko spots and dots on the one hand, and diminution to the 

 vanishing point on the other ; other specimens of the same family^ 

 showing the increase or suppression of the eye-like spots on the 

 upper surface ; four species in which the dark markings have been 

 more or less suppressed, and the light markings consequently ren- 

 dered more prominent ; a specimen of the painted lady in which, 

 the white markings at tip have been replaced by the ground colour ; 

 six species representing the effect of starvation ; a series of 

 tortoiseshell butterflies showing the difference between those which 

 emerged before and after a storm respectively ; three species 

 representing the effect of cold ; eight species showing the effect of 

 Bun burning or bleaching ; a series of magpie moths with united 

 spots ; four species exhibiting the rare occuiance of being male on 

 one side, and female on the other ; six monstrosities ; and two 

 species showing how a new fringe has grown on the mutilated edge 

 of a portion of the wing destroyed by ichneumons. 



The enlarged water colour drawings of the butterflies and moths- 

 referred to above were executed by Dr. Knaggs' son-in-law, Mr^ 

 C. C. Hodson, and bis wife and sister.
