Agriotes. | SERRICORNIA. 109 
portionately, less evidently pubescent, and having the interstices 
narrower and not so closely punctured ; the thorax also is more closely 
and distinetly punctured ; the species most closely resembles Adrastus 
limbatus in size and general appearance, but may at once be known by 
its longer and less globose thorax, and by having the second joint of 
the antennz longer than the third, whereas in Adrastus it is slightly 
shorter than third, L. 33-4 mm. 
By sweeping herbage, beating young oaks, birches, hazels, &c.; generally dis- 
tributed and common throughout the greater part of the kingdom; in fact it is to 
be found on almost all young trees in woods in early spring. 
(A. pilosus, Panz. There is a specimen of this fine species in Dr. 
Power’s collection ; it is elongate, fuscous or reddish-brown, rather 
dull, clothed with rather thick greyish pubescence ; antennze moderately 
long, feebly serrate, with the second and third joints almost equal; 
thorax convex, longer than broad, thickly and strongly punctured, 
posterior angles strongly projecting and sharply carinate ; elytra long, 
with punctured striz; interstices thickly punctured and somewhat 
rugose. L. 12-14 mm. 
This species is a native of Germany, and feeds at the roots of plants 
in mountainous districts. Dr. Power’s specimen is an undoubted im- 
portation, having been found by My. Sidebotham in a collecting bottle 
given by him to a Manchester working man, who probably took it ina 
yard where timber, dye-woods, and roots were stored, as he was in the 
habit of visiting such a place.) 
DOLOPIUWS, Eschscholtz. 
This genus has been by many authors included under Agriotes, from 
which it chiefly differs in having the second joint of the antenne equal 
in length to the third, and the sides of thorax acute with the margin 
straight in front; only one species occurs in Europe, which is very 
common throughout the greater part of the kingdom. 
D. marginatus, LL. (depressus, Esch.), Elongate, rather depressed, 
colour variable, the thorax being sometimes black with margins and 
posterior angles reddish-testaceous, sometimes reddish-testaceous with 
dise only darker, and sometimes entirely reddish-testaceous ; the elytra 
are either unicolorous testaceous, or, as is generally the rule, testaceous 
with the suture broadly blackish, the sides also being sometimes darker ; 
head thickly punctured, antenne rather long, testaceous, sometimes 
more or less infuseate ; thorax longer than broad, subparallel, distinctly 
punctured, with posterior angles projecting; elytra with punctured 
stri, interstices finely and closely punctured, scarcely rugose ; under- 
side dark ; legs testaceous. L. 5-6} mm. 
By beating and sweeping in woods, &e.; generally distributed throughout the 
whole kingdom, and, as a rule, common; abundant in many localities.
