164 SERRICORNIA, { Dolichosoma. 
uncommon where it occurs; Harwich; Essex coast; Sheerness; Southend; Deal; 
Devonshire coast, on Umbellifere. 
HAPLOCNEMUS, Stephens. 
This genus contains about seventy species, which are entirely, or 
almost entirely confined to Europe, the circum-Mediterranean region, and 
the Atlantic islands; they are characterized by having the tarsal claws 
furnished with a free membrane, which is appendiculate and as long as 
the claws ; the form is comparatively short and broad, and the upper 
surface is coarsely punctured and clothed with long upright pilose pubes- 
cence; the larve live in decaying wood, and the perfect insects may be 
found in old trees, especially in winter; in summer, however, they may 
be taken on flowers, &c.; our two species are both rare; they are closely 
allied, and by some authors have been considered as merely varieties of 
one species.

H. impressus, Marsh. (pint, Redt.). Comparatively short and 
broad, oblong, convex, clothed with very long brownish pilose pubes- 
cence, of a bronze or bronze-black colour; head much narrower than 
thorax, rather sparingly punctured, antenne brownish, with second joint 
lighter, a little longer and more strongly serrate in male than in female ; 
thorax broader than long, with sides rounded, and narrowed towards 
front, broadest behind middle, not very closely and rather strongly 
punctured, but much less strongly than elytra; elytra subparallel, very 
slightly widened behind middle, very coarsely and strongly punctured, 
with uneven and rather convex shining interstices ; legs reddish-yellow, 
with the femora brownish, and the tibie sometimes darker, and the tarsi 
often fuscous on their upper side. L. 4 mm. 
Under bark of elm, oak, pear, &c.; occasionally on flowers or foliage in summer ; 
rare; Forest Hill, Surrey; Copenhagen Fields (formerly); Highgate ; Sheerness ; 
New Forest; Glanvilles Wootton; Sutton Park, Birmingham; Staires Farm, near 
Newnham-on-Severn, Gloucestershire (where I have taken several specimens under 
bark of old pear trees in January); my wife once found a specimen in my study at 
Repton, but it had probably come out of old wood from the New Forest ; Carlisle 
(under bark of elms) ; Scotland, very rare, Forth and Tay districts. 
H. nigricornis, F. Rather smaller on an average than the pre- 
ceding, which it very closely resembles, and chiefly distinguished by its 
colour, which is dark bluish-green, or greenish-blue, with a bronze 
reflection ; the pubescence is, perhaps, a little paler; the legs are some- 
what variable in colour, the tibize being either clear yellow or more or 
less infuscate, and the femora being more or less dark ; the punctuation 
of the elytra is rather coarser and more diffuse than in H. ¢mpressus, and
