At/iOtlS.] 8KRRICORNIA. 101 



and strongly punctured, antenna; 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 

 paralli-1, slightly narrowed in front, posterior angles short not carinatc, 

 upper surface thickly and rather strongly but not rugosely punctured ; 

 elytra slightly broader at base than thorax, with rather strong punc- 

 turt-d striae, 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, F. 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, disc of thorax, and suture and sides of elytra 

 dark ; from this, however, the colour ranges to that of ordinary dark 

 specimens of A. hcemorrlioidalis ; 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 thut the 

 second joint of the antennas 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. 8^-12 mm. 



On young hazels, oaks, birches, <tc. ; much less abundant than the preceding 

 species, but generally distributed throughout the greater part of England and Scot- 

 hind, and probably Ireland ; Bold records it as not abundant in the Northumberland 

 and Durham district, but according to Sharp it is common iu Scotland, so he may 

 have overlooked its occurrence or confused it with the preceding species. 



A. subfuscns, Mull. 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- 

 tennae 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 striae, 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 antennae and. 

 tarsi. L. 7-8 mm.
