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 ruji- 
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 striae with very dis¬ 
tinct punctures except towards the tip. Antennae, legs and epipleurae 
rufous. Length 11-14 mm. = .44-. 56 in. 
Habitat : Kansas, Nebraska, Colorado, Wyoming, Illinois, Mis¬ 
souri, British America. 
A. carinata Lee. —Differs from laticollis 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 mm * = 
.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,.
