Athous. | SERRICORNIA. 101 
and strongly punctured, antenne a little longer than head and thorax, 
pitchy, with the second joint much shorter than third, last joint more 
or less contracted at apex ; thorax longer than broad, with sides almost 
parallel, slightly narrowed in front, posterior angles short not carinate, 
upper surface thickly and rather strongly but not rugosely punctured ; 
elytra slightly broader at base than thorax, with rather strong punc- 
tured striz, interstices finely, but plainly, punctured; under-side of 
abdomen reddish-brown ; legs somewhat variable in colour, lighter or 
darker reddish-brown. L. 9-13 mm. 
On bracken, young hazels, birches, &c.; also by general sweeping ; very common 
and generally distributed throughout the kingdom. 
A. vittatus, I. Very closely allied to the preceding, of which it 
has by some authors been regarded as a variety ; light examples are very 
easily known by their colour, which is lighter or darker reddish-brown, 
with the vertex of head, dise of thorax, and suture and sides of elytra 
dark ; from this, however, the colour ranges to that of ordinary dark 
specimens of A. hemorrhoidalis; these can only be distinguished from 
the latter species by having the thorax more finely punctured, with the 
sides straighter before the posterior angles, and by the fact that the 
second joint of the antennz is longer and, as a rule, very little shorter 
than the third joint ; in nearly all the specimens I have seen, the species 
may be distinguished by the rather bright reddish posterior angles of 
thorax. L. 83-12 mm. 
On young hazels, oaks, birches, &c.; much less abundant than the preceding 
species, but generally distributed throughout the greater part of England and Scot- 
land, and probably Ireland ; Bold records it as not abundant in the Northumberland 
and Durham district, but according to Sharp it is common in Scotland, so he may 
have overlooked its occurrence or confused it with the preceding species. 
A. subfuscus, Mill. Smaller than either of the two preceding 
species, elongate, rather shining, head and thorax more or less dark, 
front of former and sides margins and posterior angles of latter often 
more or less broadly brownish-yellow, elytra brownish-yellow or 
brownish-testaceous; head strongly and thickly punctured; an- 
tenne rather long and slender in both sexes, but more so in 
the male than the female, yellowish-brown with lighter base, 
with the third joint not much longer than second; thorax longer 
than broad, with the sides more feebly rounded in male than in 
female, subparallel, posterior angles short, upper surface very 
finely punctured, the punctuation being sparing on disc and closer at 
sides, pubescence rather long; elytra broader at base than thorax, with 
fine striz, interstices finely but plainly punctured, pubescence short ; 
legs yellowish-brown or testaceous, tarsi with the second to the fourth 
joints decreasing gradually in length, scarcely visibly lobed. The 
species may be easily recognized by its small size and the fine punctua- 
tion of the thorax, as well as by the structure of the antenne and 
tarsi. L. 7-8 mm.
