Acanthocinus. | LONGICORNIA. 245 
than behind, with a dark fascia behind middle; legs pubescent, apex 
of tibize and tarsi bare, ovipositor of female exserted, black. LL. 12-18 
mm. 
Male with the antenne four times as long as the body; in the female 
they are only twice as long as the body. 
On pine and fir logs; local; rare in England, and probably imported; London 
district; Suffolk; Devonshire; Bath (in a confectioner’s shop) ; Hull; Manchester 
(in props for coal mines); Newcastle (on the Quayside, and probably imported with 
shipping) ; Scotland, local, amongst Scotch fir logs, Tay, Dee, and Moray districts ; in 
these localities it is sometimes not uncommon where it occurs. 
LEIOPUWS, Serville. 
This genus contains fifty species, which are chiefly confined to the 
Northern Hemisphere; several, however, have been deseribed from 
Mexico, Brazil, Peru, Chili, &c. ; three species occur in Europe, of 
which one is found not uncommonly in many parts of Britain ; they are 
allied to Acanthocinus, but are very much smaller, and have the antennez 
proportionately shorter ; the anterior coxe are only slightly distant, and 
the thorax 1s armed with a sharp and somewhat reflexed tooth behind 
middle ; the ovipositor in the female is not exserted; the larva is found 
under bark of oak, beech, wild pear, &c.; it resembles that of Acantho- 
cinus, but is less parallel and rather strongly narrowed behind, the 
prothorax being half as broad again as the eighth abdominal segment, 
whereas in A. e@dilis it is only a fifth part broader; the pupa has the 
antennee recurved upon the abdomen and breast as in the last-mentioned 
species, 
H.nebulosus, L. Oblong, black or fuscous black, thickly clothed 
with greyish pubescence, upper surface mottled with black spots and 
spaces which are free from pubescence ; antenne long with the base of 
the joints light; thorax transverse with a small but distinct spine on 
each side ; elytra rather broad, with a sprinkling of black dots and two 
dark fasciz, one before and another behind middle, which are exceed- 
ingly variable; legs dark, with base of tibia and femora ferruginous. 
L. 5-8 mm. 
Male with the antenne nearly twice as long as the body, and the 
fifth ventral segment of abdomen shorter than in the female, in which 
sex the antenne are only one and a half times as long as the body. 
In dead hedges, also on alders and other trees; rather local, but not uncom- 
mon in many districts; Dulwich, Richmond, Darenth, Westerham, Blackheath, 
Lee, Caterham, Mickleham, Coombe Wood, Cowfold, Tonbridge, &c.; Hastings; 
Dover; Portsmouth district; New Forest; Luccombe Chine, Isle of Wight ; 
Glanvilles Wootton ; Exeter ; Swansea ; Llangollen; Talyllyn; Bewdley ; Sutton Park, 
3irmingham ; Cannock Chase ; Tamworth; Repton; Lincoln; Scarborough ; Eastham 
Wood, Liverpool ; Northumberland and Durham district ; Scotland, scarce, amongst 
oak trees, Solway, Tweed, and Forth districts; Ireland, near Dublin and Belfast, 
ant probably widely distributed.
