BRITISH BEETLES. 
rogeneous alliance of species, with the parts of the 
mouth but little developed : their antennas have either 
ten or eleven joints, and are not elbowed, being either 
clavate or knobbed ; the front and middle coxte are 
globose, and the hinder transverse and semicylindric ; 
the tarsi four-jointed and simple, and the abdomen 
composed of five segments, of which only the last, or 
the last two, are free. They principally affect wood, 
but also occur in vegetable refuse, ants’ nests, and 
sandy places. Cicones variegatus (Plate VI., Pig. 6) is 
found under bark of beech, but is very rare : it has 
been taken at Bromley, Mickleham, and elsewhere. 
Sarrotrium has strong spindle - shaped antennae ; 
Colydiurn, found in burrows of Platypus in the Now 
Forest, and Teredus, which occurs in decaying stumps 
in Sherwood Forest, are very elongate; Cerylon very 
much resembles a small Ulster, and has the penulti- 
mate joint of the palpi large, and the apical joint 
needle-pointed ; Myrmecoxenus vapor axiorum, which is 
now referred to this family, is very like a small Crypto- 
phagus ; it is a very rare, or rather looal, small, 
testaceous, flat, parallel insect, and is usually found in 
hot-beds, or crawling on walls near hot-beds or dung- 
heaps ; and lastly, Langelandia anoplithalma, which 
has comparatively recently been discovered in Britain, 
must not be parsed over ; it is an elongate, parallel, 
dull-ferruginous insect, and may easily be recognized 
by having the thorax and elytra ribbed with raised 
lines or keels. 
The HisTEWDiE are hard, polished insects, usually 
square and stout in build, thick, but flat, or at most 
slightly convex ; never pubescent ; generally black, 
though sometimes spotted with rod ; and having the
