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 limesione, 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 into 
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, exhibiting on the under side enlargement of 
the ring-like 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the white markings at tip have been replaced by the ground colour ; 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 sowing tle difference between those which 
emerged before and after a storm respectively; three species 
representing the effect of cold; eight species showing the effect of © 
sun burning or bleaching; a series of magpie moths with united 
spots ; four species exhibiting the rare occurance 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 his wife and sister.
