Of the habits of this species nothing is known. 
Hah. — Canada, Massachusetts south to North Carolina, Texas and 
Arizona, Illinois, Dacota, Nebraska. 
A. iiiiltollis Cr. — Dull seneous, feebly shining, similar to egenus, but stouter. 
Anteuufe pa.ssing the middle of the thorax, aeneous, serrate from the fifth joint, 
the serrate joints wider than long; head convex, with a faint median furrow, 
surface very coarsely punctate, the occiput strigose. Thorax wider than long, 
slightly narrowed at base, sides feebly arcuate in front, oblique, with a slight 
sinuation posteriorly, lateral margin straight, defiexed in front, hind angles 
rectangular, with a moderately long, but not strongly elevated carina ; disc con- 
vex, without trace of a median impression, lateral oblique impressions feeble, 
surface rather coarsely transversely strigose with luinctures in the furrows; 
scutellum usually carinate, sometimes not; elytra faintly sinuate at the sides 
and scarcely dilated behind the middle, the apices rounded and serrulate, disc 
slightly depressed, the basal fovese feeble, surface rather coarsely imbricate; body 
beneath colored as above; prosternal lobe broadly rounded, the intercoxal pro- 
cess rather wide and truncate at apex, propleurse punctate, but not roughly nor 
closely; metasternum at sides coarsely transversely strigose. Abdomen feebly 
transversely strigose, more roughly at the sides of the first two segments; py- 
gidium sparsely punctate, the median line smooth, not carinate; claws broadly 
toothed at middle. Length .18 — .22 inch.; 4.5 — 5.5 mm. 
Male. — Front rather less convex, with more distinct median im- 
pression and more coarsely punctate. Prosternum roughly and 
ckxsely punctate, hairy. Metasternum closely punctate and slightly 
hairy ; first two ventral segments flattened at middle, closely punc- 
tate and with short hairs. 
Female. — Head more convex and more evidently strigose. Pro- 
sterjuun and metasternum transversely strigose, not {)ubescent ; first 
two ventral segments convex, not closely ])unctate and not hairy. 
The numerous specimens examined show no variation, except a 
little in size in specimens from the most remote localities. 
The species resembles egenus somewhat, but is more robust, has 
shorter antenme and an entire prosternal lobe. Specimens of lacus- 
tris have been seen which somewhat resemble this one, but the male 
characters will then readily separate them. 
Hab. — Massachusetts, Dracut (Blanchard), Florida, Georgia and 
Texas. 
.4. abditiiH n. sp. 
This species so closely resend)les imbellis that it is deemed necessary 
merely to recite the differences : 
Aiitenuffi sc.arcely passing the middle of the thorax; thorax with a vague me- 
dian depression; prosternal lobe truncate, or feebly emarginate. Length .18 — 
.20 inch. ; 4.5 — 5 mm.
