width, hind angles carinated, obtuse, basal impressions deep, punctured. 

 Elytra rather finely striate, punctures small but distinct. Legs rather 

 dark rufous, antennae rufo-piceous, stout. Length 11-12 mm. =^ .44- 

 .48 in. 



Habitat: Canada, Northwest Territory, New Hampshire (Mt. 

 Washington). 



A. rufimanus Kirby. — Blackish, with very distinct greenish 

 tinge, shining, form elongate. Thorax short, moderately narrowed 

 posteriorly, sides rounded and with a sharp sinuation near the hind 

 angles which are rectangular and prominent ; basal impressions deep, 

 punctured and with an acute carina on outer margin. Elytra very 

 long, sides parallel, striae well marked and distinctly punctured except 

 toward the tip. Legs and antennae rufous. Length 11. 5-12 mm. = 

 46-. 48 in. 



Habitat : Canada, Wisconsin, Wyoming, Colorado, Magdalen 

 Island. 



The above description is made out from a pair named lacustris 

 Lee, in my collection. The name is considered a synonym of rufi- 

 manus Kirby, though there is little of value in the last description. 



A. laticollis Lee. — Broader and more oblong, piceous black, less 

 shining, thorax larger in proportion to the elytra which are more 

 rounded on the sides. Sides of thorax much rounded, sinuate near 

 base, hind angles hardly as prominent as in rufimanus, basal foveae 

 deep, the carina well marked and acute. Elytral stri^ with very dis- 

 tinct punctures except towards the tip. Antennae, legs and epipleurae 

 rufous. Length 11-14 "coxa.. = .44-. 5 6 in. 



Habitat : Kansas, Nebraska, Colorado, Wyoming, Illinois, Mis- 

 souri, British America. 



A. carinata Lee. — Differs from latieollis by the characters given 

 in the table. These points are to be made out with tolerable ease from 

 comparison though seemingly rather indefinite. Length 12-15 '^'^- = 

 .48-.60 in. 



Habitat: New Mexico, Colorado, Manitoba, Illinois. 



A. elongata Lee. — Elongate, oblong-ovate, slender, rufo-piceous, 

 thorax about equal in length and breadth, sides rounded, hind angles 

 somewhat obtuse, basal foveae bistriate, punctate, carina broad, not 

 much elevated. Elytra broader than the thorax and with fine striae 

 which are finely punctate anteriorly. Length 10 mm. := .40 in. 



Habitat : Lake Superior region. 



A. hyperborea Dej. — Moderately elongate, ^blackish piceous,.
