TRECHID^E. 47 



DESCPiIPTION. 



This species upon a slight inspection might be mistaken for an Argutor, 4 but it exhibits all the 

 most important characters of the genus under which I have placed it. The body is black, some- 

 what glossy. The tip of the palpi and scape of the antenna? are rufous : the prothorax is rather 

 wider than long, but nearly square ; the short basilar furrows observable in Argutor distinguish this 

 species from the succeeding ones : elytra lightly furrowed, furrows impunctured ; in the usual situa- 

 tion adjacent to the second furrow a little beyond the middle of the elytrum a very minute puncti- 

 form impression is just discernible ; the lateral margin and suture at the apex of the elytra are 

 reddish : the tibiae are rufous but the cubit is black at the tip ; the tarsi are darker, the hand has 

 four dilated joints as in the other species of the genus.

T. (ruficrus) niger ; antennis scapo, pedibus, prothoracisque rnargine, rufis : elytris luridis : litura pone medium nigricanti. 

 Red-legged Trechus, black ; scape of the antenna?, legs, and margin of the prothorax, rufous ; elytra lurid with a blackish 

 blotch beyond the middle.

DESCRIPTION. 



Body black, glossy. Palpi piceous ; scape of the antenna? and mouth rufous : prothorax subob- 

 cordate ; channelled, channel not abbreviated, margin rufous especially the basilar ; angles rounded ; 

 basilar impressions single, round, and punctured : elytra lurid or dirty yellow with a large blackish 

 cloud or blotch beyond the middle : legs dull rufous, thighs darker. 



(69) 3. * Trechus flavipes. Yellow-legged Trechus. 



T. (flavipes) piceus, nitidus; capite subtus, ore, antennis, prothorace, elytrisque limbo, rufescentibus ; palpis pedibusque flavis. 

 Yellow-legged Trechus, piceous, glossy; head underneath, mouth, antennae, prothorax, limb of the elytra, more or less 

 rufous ; palpi and legs yellow. 



Length of the body 2j lines. 



Many taken in Lat. 54°. 



i I suspect that the genus here quoted, consisting also of minute species, and inhabiting moist places, (see above p. 30, 

 note 5) belongs rather to the present subsection than to the Geadephaga ,- Trechus tibialis seems to lead from Argutor to 

 Trechus.
