85. Notaphus [Bembidium] variegatus, Klvby. — Length of body If 

 lines. 



This also is related to N. nigripes, but is quite distinct. The head and 

 prothorax are without any green tint; the antenoae are not longer than the 

 prothorax ; the prothorax is proportionally not so wide before and narrower 

 behind : elytra scarcely at all bronzed j lurid with a large blackish cloud or 

 spot near the base, another near the apex, and an intermediate black angular 

 band j the furrows of the elytra, especially the external ones, do not reach 

 the apex, or at least are obliterated; they are punctured the whole of their 

 apparent length j instead of two, there are three punctiform impressions; the 

 legs are rufo-piceous. [This name is preoccupied by Say's species; Le Conte 

 considers Kirby's species synonymous with B. versicolor Lee] 



[59] 86. Bembidium impressum, Gytt. — Length of body 2 1 lines. 

 Taken frequently in lat. 54° and 65°, and in the journey from New York to 

 Cumberland House. On the sandy shores of Lake Winnipeg, in the spring 

 of 1825 (Mr. Drummond). In Canada (Dr. Bigsby). 



[60] Body underneath green, bronzed, very glossy ; above bronzed, gloss 

 much obscured, occasioned by an infinity of most minute reticulations, visible 

 only under a good magnifier, which give it a granulated appearance; frontal 

 impressions and ocellated punctures as in Notaphus; eyes very large and 

 prominent; palpi bronzed, with the second joint obscurely rufous ; antennas 

 longer than the prothorax, with the scape and the base of the second and 

 third joints rufous ; prothorax short, depressed both at the base and apex, 

 the depressed part being wrinkled longitudinally ; dorsal channel and basilar 

 impressions rather deep ; in the latter are two little furrows ; in the elytra, a 

 little beyond the middle, in the interstice between the second and third 

 furrows, are two quadrangular, oblong, slightly depressed spaces, of a some- 

 what golden lustre, and marked at the anterior end with a punctiform impres- 

 sion ; immediately before, between, and after the depressed spaces, is a 

 levigated and rather elevated one of the same shape ; the furrows of the 

 elytra are arranged nearly in the same way as those of Notaphus intei '/is, 

 above described : the legs are rufous, with the thighs bronzed at the apex. 



[Taken in Canada.] 



Genus Opisthitjs, Kirby. 



Oral organs scarcely different from those of Elaphrus. 



Body depressed and flat. Head triangular, antennas much more slender 

 and longer than those of Elaphrus, 3rd joint rather longer than 1th. Pro- 

 thorax very short, transverse, scarcely wider than the head ; anteriorly 

 obsoletely obtus-angular, posteriorly subrepand, depressed a little at base and 

 apex; chanelled, but without basilar impressions ; sides gibbous ;. angles all
