BRITISH BEETLES. 
when feeding on the latter, becomes of a much darker 
colour j and A. sanguinea, found in May-blossom, is of 
a bright red tint. 
The Galerucze are mostly narrow in shape, dull- 
yellow or brown in colour, roughly granulated, covered 
with a close powdery grey pubescence, and grega- 
rious ; being found in numbers on willows and water- 
plants. Their larval, — which are sluggish, rather 
elongate, wrinkled, and with lateral tubercles and an 
anal projection, serving as an extra leg, — live in 
company, and commit great ravages, often stripping 
every leaf off the trees, &c., on which they feed. 
Agelastica halensis, very common in the south, 
abounding in grassy places towards the autumn, is 
our brightest species ; it is upwards of a quarter of 
an inch long, with its broad elytra and the top of its 
head bright green, more or less running into dark 
blue, its mouth, thorax, body and legs yellow, and 
tarsi, antennas, and tips of tibiae black. 
Pliyllobrotica (Auchenia), adorned with four spots, 
and the narrow delicate Calomicrus circumfusus (Plate 
XIV., Fig. (3) are the only species ive possess that 
can be considered as at all variegated in markings ; 
the latter (in which the elytra always gape somewhat) 
has much the facies of certain of the Halticina, and 
lives gregariously on the dwarf furze. 
Finally, Luperus, elongate, feebly-built, with very 
large granulated eyes, and exceedingly long and 
fragile antennae (especially in the male ; whose body, 
also, is longer), of which the second joint is minute, 
occurs plentifully on alders, and other marsli-loviug 
trees. 
The Halticina are at once distinguished from the
