portionatcly, less evidently pubescent, and having tho interstices 

 narrower and not so closely punctured ; the thorax also is more closely 

 and distinctly punctured ; the species most closely resembles Adratttus 

 liiiilxitua 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 

 th'- ant. inia- longer than the third, whereas in Adrastus it is slightly 

 shorter than third. L. &-4 mm. 



Uy sweeping herbage, beating young oaks, birches, hazels, &c. ; generally dis 

 tiilmti-d and common throughout the greater part of the kingdom ; in fact it U to 

 bt- found ou almost all young trees in woods in early spring. 



(A.pilosus, Panz. There is a specimen of this fine spocies in Dr. 

 Power's collection; it is elongate, fuscous or reddish-brown, rather 

 dull, clothed with rather thick greyish pubescence ; antennae moderately 

 long, feebly serrate, with the second and third joints almost equal ; 

 thoiax convex, longer than broad, thickly and strongly punctured, 

 : ior angles strongly projecting and sharply carinate ; elytra long, 

 with punctured striae ; 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 Mr. Sidebotham in a collecting bottle 

 given by him to a Manchester working man, who probably took it in a 

 yard win-re timber, dye-woods, and roots were stored, as he was in the 

 habit of visiting such a place.) 



DOXiOPIUS, Eschscholtz. 



This genus has been by many authors included under Agriotes, from 

 which it chiefly differs in having the second joint of the antennae 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. margrinatus, L. (deprcssvs, Esch.). Elongate, rather depressed, 

 colour variable, the thorax being sometimes black with margins and 

 posterior angles reddish-testaceous, sometimes reddish-testaceous with 

 disc 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, antenna rather long, testaceous, sometimes 

 more or less infuscate; thorax longer than broad, subparallel, distinctly 

 punctured, with posterior angles projecting ; elytra with punctured 

 striae, interstices finely and closely punctured, scarcely rugose ; under- 

 side dark; legs testaceous. L. 5-6J mm. 



By boating and sweeping in wood*, Ac. ; generally distributed throughout the 

 whole kingdom, and, as a rule, common ; abundant in many localities.
