April it has been found in great numbers under 
stones by the sea-shore ; and in May it has been 
seen congregated upon a yellow ranunculus or 
buttercup in an osier-holt. It abounds also on 
grass, in hedges, corn-fields, &c.; and specimens 
of it have been obtained as late as July, with 
the pups and exuvie. Bouche says that its 
larvee live sometimes in great multitudes in dung 
and vegetable earth. 
The rufous-rumped click-beetle, Athous rufi- 
caudis—called by Gyll Hlater ruficaudis, by Oli- 
vier Hlater sputator, by Herbst Elater analis, and 
by Fabricius Hlater hemorrhoidalis—is long, nar- 
row, piceous, and shining, and clothed with 
ochreous and longish hairs. The antenne are 
dusky, and similar in their relative proportions 
to those of Cataphagus obscurus, but a little 
longer and compressed; the basal joint is stout, 
the second and third slender, the remainder ob- 
trigonate, the apical one narrower, the tip coni- 
cal, The head and the thorax are black, and 
thickly and minutely punctured; the former is 
semi-orbicular, with truncated and reflexed cly- 
peus; the latter is much longer than broad, a 
little narrowed towards the anterior angles, the 
posterior spines short and trigonate, and the 
margin beneath projecting considerably in a 
semicircle to receive the head. The scutel is 
black. The elytra are reddish brown, and twice 
as long as the head and thorax, being rather 
broader than the latter, but linear, the apex 
ovate, and the tip of each rounded; and they 
are minutely punctured, with nine striz on each. 
The abdomen is ferruginous. The legs are short 
and ferruginous. The feet appear four-jointed 
until magnified ; and are very pubescent beneath, 
—the basal joint the longest, the second and 
third decreasing in length, slender at the base, 
and somewhat trumpet-shaped, the apex fur- 
nished with a membranous margin,—the fourth 
minute,—the fifth long, slender, and terminated 
by two simple claws. The length of the insect 
It is abun- 
dant from April till the end of June in corn- 
fields, on nettles, on commons, in pastures, &, 
It has been observed in the beginning of June 
flying about hedges and banks, and in May in- 
festing the oak-leaves and underwood in exten- 
sive woods. 
The satin-coated click-beetle, Lepidotus holo- 
sericeus—called by Linneus “later holosericeus— 
is the first of the eight species which are but 
presumptively known to produce the destructive 
wire-worms. It is elliptical or boat-shaped, deep 
brown, thickly and minutely punctured, and 
clouded with silky ochreous pubescence. The an- 
tenn are scarcelyso long as the head and thorax, 
and are slightly pubescent, and eleven-jointed ; 
the basal joint the stoutest, somewhat chopper- 
shaped, and chestnut-coloured,—the second mi- 
nute,—the third long, slender, and clavate,—the 
fourth and six following produced internally and 
obtrigonate,—the apical joint elongate - ovate,

and the apex narrowed, The head is small. 
The palpi and eyes are black. The thorax is 
convex, semi-ovate, concave before, broadest at 
the base, which is bisinuated, the angles pro- 
duced, each forming a strong trigonal lobe, not 
very acute; the pectoral lobe rather small and 
tapering. The scutel is large and orbicular. The 
elytra are more than twice as long as the tho- 
rax, and scarcely broader at the middle, the 
ochreous pubescence often forming two ocelli on 
the disc; and there are nine punctured strie on 
each elytron, most distinct at the base. The 
wings are ample. The legs are short, slender, 
and pale ferruginous. The length of the insect is 
5 lines, and its breadth 2, This click-beetle has 
often been observed in corn-fields, and also found 
under stones and on birch-trees ; and it continues 
from the end of April till August. 
The mouse-coloured click-beetle, Agrypnus 
murinus—called by Linneeus Hlater murinus—is 
rather broad and boat-shaped, and entirely clothed 
with very short ash-coloured depressed hairs, 
marbled with brown, more or less ochreous, and 
is thickly and minutely punctured. The anten- 
ne are shorter than the thorax, rather stout, and 
eleven-jointed, of bright ferruginous colour, the 
basal joint stout, oblong, and piceous,—the se- 
cond small and semiovate, —the third smaller 
and pear-shaped,—the fourth and six following 
compressed, produced internally, and obtrigonate, 
—the apical joint longer and ovate,—and the 
apex suddenly narrowed. The head is semi-or- 
bicular and depressed. The eyes are scarcely 
visible. The thorax is twice as broad, orbicular, 
convex on the back, with two tubercles on the 
disc; beneath are two deep fissures to receive 
the antenne, and the pectoral spine is long and 
attenuated, and the apex subulate. The scutel 
is ovate-conic. The elytra are a little broader | 
than the thorax, and more than twice as long,— 
the hinder portion attenuated,—the apex round- 
ed, sloped suddenly towards the thorax at the 
base; and there are nine indistinctly punctured 
striz on each elytron, and the costal margin is 
deeply emarginate to receive the hinder thighs. 
The wings are ample. The legs are short and 
shining pitchy. The tips of the thighs and the 
tarsi are fulvous; and the latter are five-jointed 
and tapering,—the basal joint the stoutest and 
the longest in the hinder pair. The claws are 
moderate and acute; the tibie are rough, with 
series of minute bristles. This insect is com- 
monly about 6 lines long and 25 broad; but’ is 
sometimes much larger. It is found in corn-fields 
and in sandy places from the end of April till the 
early part of autumn. 
The tawny-legged click-beetle, Melanotus fulvi- 
pes—called by some entomologists Hater fulvipes 
and by others later castanipes—is very long, 
narrow, and shining black, thickly punctured, 
and clothed with very short fine ochreous pu- 
bescence. The antenne are as long as the thorax, 
compressed, pubescent, fulvous, and eleven-joint-
