(32) 8. * Agonum erythropum. Red-legged A gonum. 



A. (erythropumj nigrum, nitidum, supra nigro-aneum ; prothorace postice angustiori; elytris trifoveolatis , pedihus rufescentibus. 

 Red-legged Agonum, black, glossy, above bronzed ; protborax narrower bebind ; elytra witb three punctiform impressions ; 

 legs dusky rufous. 



Length of tbe body 4^ lines. 



Taken in Canada by Dr. Bigsby. 



DESCRIPTION. 



Body glossy, black underneath, above bronzed. Antenna; black with the scape dusky rufous : 

 prothorax tinted with copper, obcordate with rounded angles ; basilar impressions round and deep : 

 elytra tinted with copper, with three nearly obsolete punctiform impressions in the usual situation : 

 legs dusky rufous ; in other respects it resembles A. seminitidum. 



This species appears to be the American representative of A. parumpunctatum. It is, however, 

 larger, more bronzed, the impressions are less distinct and more distant, and the thighs as well as 

 the tibia; and tarsi are rufous.

PLATE I, FIG. 4. 



Length of the body 4 — 4J lines. 



Many specimens of this lovely Agonum were taken in Lat. 54°. It appears to 

 be very common in North America, where it represents A. sexpunctatum, the most 

 brilliant of our European species, but which A. cupripenne far exceeds in beauty. 



DESCRIPTION. 



Body glossy, underneath black with a slight shade of green, especially on the head and breast. 

 Head above of a fine green, glossy, smooth with the usual frontal impressions ; mouth, excluding 

 the upper-lip and palpi, rufous ; antenna; longer than the prothorax, black, scape tinted with green : 

 prothorax green, channelled, basilar impressions rather deep : scutellum green : elytra 4 lightly fur- 

 rowed, furrows impunctured, three (four?) minute equidistant punctiform impressions, in the usual 

 situation, the anterior one adjacent to the third furrow, and the two posterior ones to the second ; 

 as to colour these organs are of a fine cupreous purple, with the base and sides of a lovely green : 

 legs black with the four anterior trochanters and the base of the posterior, rufous. 



In the male the posterior trochanters are entirely black.
