Anobium.] SERRIOORNIA. 191 
Hastings ; Glanvilles Wootton ; New Forest (common); Swansea; Llangollen ; 
Evesham ; Trench Woods; Gloucester; it appears to be confined to the South Mid- 
land and Southern districts, as far as is at present known. 
A. paniceum, L. (Sitodrepa panicea, Thoms.; Artobium paniceum, 
Muls.). Oblong, subcylindrieal, convex, of a rather shining ferruginous 
or reddish-testaceous colour, clothed with greyish or whitish pubescence ; 
antenne and legs clear reddish-testaceous; eyes hairy ; thorax even, 
narrowed in front, with the sides gradually rounded; elytra with fine 
punctured strie, interstices rather broad, very finely punctured; legs 
slender. L. 2-3 mm. 
The antenne are shorter in the female than in the male, and have the 
three last joints less elongate. 
A common cosmopolitan species, occurring in old flour, bread, biscuit, skins, 
medical stores, &c.; it has been introduced into many of our large towns, and 
gradually spread; in Scotland it appears only to have been recorded hitherto from 
the Forth district. 
XESTOBIUM, Motschulsky. (Cnecus, Thoms.) 
This genus contains four EKuropean species, which may easily be dis- 
tinguished from all our other Anobiina except Hrnobius by the absence 
of striz on the elytra; from Ernobius they may be known by their 
stouter tibia and the broad fifth joint of the tarsi; our single species 
X. tessellatum is the largest of the British Anobiide; it is not un- 
common locally in old decaying stumps and in old buildings; its larva 
is figured by Westwood (Classification, i. p. 269, fig. 30, 11); a 
reference to this figure will at once show the very close resemblance it 
bears to the Lamellicorn larve by reason of its curved form and the 
enlarged last segment of the abdomen. 
X. tessellatum, F. (rufo-villosum, De G.; pulsator, Schall.). A 
large and conspicuous species, convex, subcylindrical, of a dark chocolate- 
brown colour, thickly tessellated with patches of yellowish pubescence, 
which gives the upper surface a variegated appearance ; the sculpture of 
the upper surface is finely and thickly scabrous; head rather deeply 
sunk in thorax, eyes moderately large, convex ; antenne reddish, rather 
short and stout; thorax about as broad as elytra, contracted in front, 
with the anterior and posterior margins produced, central furrow 
obsolete ; scutellum semicircular; elytra parallel-sided, with traces of 
raised lines; legs ferruginous, stout and robust, tarsi short and broad, 
with the fifth joint transverse. L. 5-7 mm. 
In old trees, willow, oak, &c.; often in old wood in houses and churches ; London 
district, common and generally distributed ; Ulting, Essex; Suffolk; Pegwell Bay ; 
St. Peters; Hastings; Glanvilles Wootton; New Forest; Devon; Swansea; 
Cromer ; Windsor; Henley; Repton; Needwood, Staffordshire; Dunham Park, 
Manchester ; not recorded from the Northumberland district ; Scotland, very rare, 
Solway district ; ‘ Rachills,’ Rey. W. Little, Murray’s Cat.
