92 THE CANADIAN ENTOMOLOGIST. 



the following species, oblong-ovate, with the lateral margin piceous, and not 

 dilated posteriorly as in the majority ; basilar impressions rather shallow, 

 oblong : elytra oblong, rufo-piceous, slightly furrowed, furrows impunctured; 

 five punctiform impressions between the second and third ; the three anterior 

 ones adjacent to the latter, and the two posterior to the former : legs dusky 

 rufous. 



Variety 13. With only four punctiform impressions, legs paler. 



C. With the 2nd, 3rd and 4th joints of the antennae piceous, the 



rest ferruginous : impressions of the elytra as in B. 



D. Larger, elytra with five impressions, in other respects like C 



This species appears very like A. lenum, Dej., which is also North Ameri- 

 can, but the colour of the underside of the body and of the head and pro- 

 thorax is different. [Belongs to Platynus.] 



27. Agonum sordens, Kirhy. — Length of the body three lines. Two 

 specimens taken in lat. 54°. 



Body black, glossy. Head rhomboidal ; mouth, mandibles at the tip, 

 palpi at the base, and scape of the antennae, rufous; frontal impressions very 

 slight : prothorax scarcely longer than wide, narrowest behind ; dorsal chan- 

 nel rather deep ; lateral margin underneath testaceous ; basilar impressions 

 oblong, deepish : elytra dusky-testaceous, in one specimen a little bronzed, 

 slightly furrowed, furrows impunctured ; between the second and third are 

 five punctiform impressions placed as in the last species : epipleura and legs 

 testaceous. 



[26] Agonum melanarium, De Jean. — Length of the body 4f lines. 

 Taken in lat. 54°. 



Body black, glossy. Mandibles at the tip, mouth and scape of antennas, 

 piceous : prothorax nearly as long as wide; disk transversely wrinkled; late- 

 ral margin at the base much dilated, rather incrassated, and sub-angular; 

 posterior impressions large and distinctly punctured : elytra wider than the 

 prothorax, sub-emarginate at the base , distinctly furrowed with very minute 

 and inconspicuous punctures in the furrows ; three punctiform impressions 

 in the third furrow from the suture : legs piceous. 



This species is the American representative of A versutum, which it much 

 resembles. [Belongs to Platynus ; taken at Ottawa by Mr. Billings.] 



29. Agonum seminitidum, Kirhy. — Length of body 4^ lines. Taken in 

 lat. 54°. 



Body smooth, glossy, black underneath. Head greenish-bronzed, very 

 glossy, with frontal impressions lunular ; antennae longer than the prothorax; 

 prothorax greenish-bronzed with a copper tint, very glossy, channelled, disk 

 transversely and minutely wrinkled ; basilar impressions longitudinal, lateral
