NORTH AMERICAN OOLEOPTERA.

arranged in the usual manner; body beneath more sliining than above; proster- 
nal lobe truncate and vaguely einarginate, intercoxal process rather broad, trun- 
cate at apex, propleurse coarsely punctate, sparsely pubescent; metasternum at 
sides rather roughly strigose and punctate. Abdomen moderately closely punc- 
tate, strigose at sides of first two segments; pygidium sparsely punctate, with a 
smooth median line; claws cleft, forming a broad tooth. Length .28 inch. ; 7 mm. 
Male. — Prosternum densely punctured, pubescent; first two ven- 
tral segments very feebly impressed along the middle, scarcely pu- 
bescent ; tibite not mucronate. 
Female. — Prosternum less roughly punctate, not pubescent ; ven- 
tral segments not impressed. 
The two specimens before me do not vary. The types are before 
me and show that while the species is fairly, but too briefly described 
by Crotch, its position in his analytical table is erroneous. He men- 
tions pubescent patches at the sides of the last three ventral segments, 
but this is merely the result of a slightly denser punctuation. 
Hah. — Northern Florida, probably near Jacksonville. 
A. addeiidiis Crotch. — Moderately robust, dull cupreo-aeneous, subopaque, 
elytra with three pubescent spots on each side, sometimes absent or very faint. 
Antennae piceous, serrate from the fifth joint, reaching the middle of the thorax ; 
head, from above, concave, a moderately deej) impression from the occiput to the 
clypeus, surface rather roughly granulate-strigose, sparsely pubescent. Thorax 
very little wider than long, slightly narrowed posteriorly, sides feebly arcuate, 
slightly sinuate in front of hind angles, which are rectangular and with a 
straight, well defined carina; disc convex, with at most a feeble median impres- 
sion, which may he entirely absent, lateral oblique impression moderate, surface 
closely transversely strigose; scutellum transversely carinate; elytra feebly 
sinuate at sides and but little broadened, apices rounded, feebly serrulate ; disc 
slightly flattened, a vague channel each side of suture, basal fovese feeble, surface 
moderately closely, but not roughly imbricate, the pubescent spots, when present, 
as in fall ax ; body beneath more shining than above; prosternal lobe obtusely 
rounded, with a vague sinuatiou at middle, intercoxal process parallel, squarely 
truncate at apex, propleurfe shining, indistinctly reticulate; metasternum at 
sides roughly punctate-strigose and with the episternum and outer side of coxal 
plate pubescent. Abdomen sparsely punctate, strigose at sides of first two seg- 
ments, the vertical portion of first two segments densely pubescent ; pygidium 
sparsely punctate, not carinate; claws broadly toothed. Length .1,5 — .24 inch.; 
4 — 6 mm. 
Male. — F rout with simply the longitudinal depression. Prosternum 
densely punctured and hairy. Metasternum flat, as densely punc- 
tured as the prosternum ; first two ventral segments feebly impressed 
along the median line. 
Female. — Front often with a crescentic, transverse impression in 
addition to the median. Metasternum convex, sparsely jiunctate; 
ventral segments not impres.sed.
