Brachytarsus. | RHYNCHOPIORA. 111 
of the antennz is twice as long as the third, whereas in B. fasciatus 
it is scarcely longer. L. 23-4 mm. 
In decaying white-thorn, and also on firs and hazels ; local; London district, rare, 
Darenth, Forest Hill, and Ripley (Surrey); Portsmouth district; New Forest; 
Llangollen ; Northampton; Repton, Bretby Wood (on firs, in some numbers and 
very variable in size); Nocton near Lincoln; Scotland, local, amongst old hazel 
bushes ; Solway district; Stephens records it as common in the north and in Scot- 
laud, but I know of no localities in that country except the one last mentioned. 
MACROCEPHALUS, Olivier (Anthribus Schénherr). 
This genus contains one large and conspicuous European species which 
may at once be known by the fact that the antenne are nearly as long 
as the body in the male; it thus forms a transition between the Longicornia 
and the Rhynehophora ; the rostrum is deeply incised at apex ; the third 
joint of the antennz is much longer than the second and the club is not 
abrupt ; the eyes are emarginate ; the thorax has no distinct transverse 
keel before base and the anterior cox are evidently separated; the 
species is found in rotten wood. 
M. albinus, L. Oblong, subeylindrical, dusky brown, sometimes 
almost black, with the rostrum, forehead, anterior margin of thorax, apex 
of elytra and a larger or smaller spot on each towards suture thickly 
covered with white scales ; extreme apex of elytra with a fuscous spot ; 
antenne dark with the eighth and base of the ninth joints white; 
thorax with the sides slightly rounded and narrowed in front, with three 
tubercles on disc, arranged horizontally ; elytra with punctured striae, 
coloured as above, and further with more or less distinct series of black 
silken tufts, somewhat widened behind; legs rather long annulated with 
brown and white pile. L. 7-10 mm. 
Male with the antenne not or scarcely shorter than the body. 
Female with the antennz comparatively short, not reaching much 
beyond base of thorax. 
In decaying trees, especially oaks, willows, and birches; very local and, as a rule, 
rare ; London district, very rare, Ashford (Kent), Eltham, Darenth Wood, Graves- 
end ; formerly in Kensington Gardens ; Abbots Wood; Folkestone; Guestling near 
Hastings ; Dorset ; Norfolk; Bewdley Forest, where Mr. Stevens says it was formerly 
common ; it does not, however, appear to have been met with by Mr. Blatch, who 
has collected so much in this locality ; abundant nar Newcastle (@. Wailes); in 
Mr. Bold’s catalogue there is a note to the effect that it used to be met with in 
plenty at Gibside, but none have been taken for many years past; Mr. Wailes’ speci- 
mens are probably the ones referred to. 
PLATYRRHINUS, Clairville. 
This genus is represented by one large species, which is found in 
fungi on old ash trees, and also in decaying beech, birch, and alder ; 
it is the largest representative of the family that occurs in Europe ; the 
antenn are short and terminate in a well marked three-jointed club ; 
the eyes are round and entire and the rostrum is not bilobed ; the thorax 
has a strong projection on each side a little behind middle and the keel
