tarsi, especially in the male ; which, as usual, is 
rather smaller, not quite so dull, and has longer legs. 
Its larva is also frequently to be seen clinging to low 
plants in lanes and on commons: it is of a shining 
bluish-green colour, very convex, and elevated in the 
middle. 
Chrysomela distingumda (Plate XIV., Fig. 5) is not 
uncommon near London, in grassy places, on the 
flowers of Antirrhinum, &c. ; the contrast of colour 
afforded by its dark blue-black elytra, broadly mar- 
gined with orange, being very effective. 
C. menthastri and graminis, two of the largest, are 
especially conspicuous from their somewhat oblong 
form and uniform rich green metallic hue, which, in 
graminis especially, runs to blue and coppery reflec- 
tions ; but 0. cerealis , striped longitudinally and alter- 
nately with purple, green, gold, and reddish copper, 
is perhaps the. most handsome. It is found at the 
roots of wild thyme on Snowdon. The commonest 
species is C. polita, abundant in grassy places ; it is 
shining, blue-green, with reddish-brown elytra, round 
and convex ; and it is from the general rotundity and 
convexity of the members of this section that the 
name of Cyclica has been applied to it. 
Of the allied species, Lina populi and tremulse de- 
serve notice : both are blue-black with brown win<r-

cases, and not uncommon on poplar and aspen ; the 
former being distinguished by its larger size, and a 
small black spot at the apex of its elytra. They are 
gregarious in their habits ; L. tremulse being often 
found in great numbers and in all its stages on the 
same tree. The larvae, which are tuberculated, whitish, 
and adorned with straight rows of dark-brown spots
