30 NORTHERN ZOOLOGY. 



XIV. Genus ARGUTOR. 5 Meg. 



(36) 1. * Argutor bicolor. Two-coloured Argutor. 



A. (bico!o7') nitidus, supra nigcr, subtus, (interims, pedibusque brunneis ; prothorace toto leevi utrinque sulculo impresso ,• eh/lri.< 



trifoveolatis. 

 Two-coloured Argutor, glossy, above black; underneath, antennae and legs, mahogany-coloured ; prothorax impunctured 



with a little furrow impressed on each side ; elytra with three punctiform impressions. 



Length of the body 3 lines. 



Taken twice in Lat. 54°. 



DESCRIPTION. 



Body glossy, above black, beneath mahogany-coloured. Antenna?, and palpi at the base, dark 

 mahogany-colour : prothorax longer than wide, rather narrowest at the base where it is slightly 

 sinuated, anterior angles rounded, without punctures, dorsal channel slightj a deep short basilar fur- 

 row on each side : elytra slightly furrowed with impunctured furrows, the seventh from the suture 

 obsolete ; in the interstice between the second and third are three punctiform impressions, the ante- 

 rior one adjoining the latter, and the two posterior ones the former. 



This species approaches very near to A. erythropus De Jean, 6 but it is smaller, and the posterior 

 angles of the prothorax are not rounded. The underside of the body, the legs, and antenna? are all 

 of the same colour, sometimes a little darker, at others a little paler. 



(37) 2. * Argutor femoralis. Black-thighed Argutor. 



A. (femoralis) nitidissimus, ater ; antennis scapo, tibiis tarsisque piceis ; prothorace toto l&vi, utrinque basi sulculo impresso; 

 ebjtris trifoveolatis, striatis : striis antice subpunctatis. 



Black-thighed Argutor, very black and glossy; scape of the antennae, tibioe and tarsi, piceous ; prothorax impunctured, on 

 each side at the base with a little furrow ; elytra with three punctiform impressions, furrowed, furrows anteri- 

 orly slightly punctured. 



Length of the body 3^ lines. 



Taken in Lat. 54°. 



DESCRIPTION. 



This species approaches very near to the preceding one, and its place is between that and A. ver- 

 nalis, of which last it is the American representative. It differs from A. bicolor chiefly in having 

 only the scape of the antennae and the tibia? and tarsi of a different colour from the rest of the body 

 and in having the anterior half of the furrows of the elytra slightly punctured; and from the latter 

 in having the prothorax narrower at the base, with only a single impunctured impression on each 

 side. 



5 This genus, or subgenus, the species of which are usually minute and inhabit moist places, differs chiefly from Pcecilus 

 in having the third joint of the antennae longer than the fourth, without any ridge, and in the basilar impressions of the 

 prothorax being mostly single.
