easily separable by the fact that tbe former lias a well marked j)ro- 
jecting Carina, while this has not. The occipital impression gives 
the appearance from above of a bilobed head, and the impression 
does not extend downward on the front, while in rnficollis the occiput 
is rather concave and the impression reaches the clypeus. 
Occurs in Florida at St. Augustine. 
•\. aiij^elicus ii. sp. — Form rather robust, as in muticus ; color brassy, mod- 
erately shining. AuteuiiEe piceoiis, bronzed, not reaching the middle of the 
thora.x, serrate from the fourth joint. Head slightly convex, a finely impressed 
line from the occiput to the clypeus, surface finely, not closely strigose, sparsely 
punctate, clypeus much broader at base than long at middle. Tliorax broader 
long, base and apex equal, sides arcuate in front, sinuate behind the middle, 
hind angles rectangular with a short, acute, straight carina, disc convex, a vague 
median depression, another broad depression at the sides; surface transversely, 
not coarsely strigose with intermediate sparse punctures; scutellum not trans- 
versely carinate ; elytra distinctly sinuate behind the humeri and broader bebind 
the middle, the apices separately rounded and very feebly serrulate ; disc convex, 
without trace of costae, the basal depressions moderate, surface rather finely im- 
bricately sculptured ; body beneath more shining than above; prosternal lobe 
obtuse, broadly but feebly emarginate, the intercoxal process gradually narrow- 
ing, the apex acute, propleurae with reticulate sculpture; metasternum coarsely 
punctate, reticulate. Abdomen finely punctate-strigose at middle, a little more 
coarsely at the sides, the first segment but little more rugose; pygidium coarsely 
punctate, feebly carinate ; claws similar on all the feet. Length .25inch.: 6.5 mm. 
The only specimens seen are females, and sliow no secondary sexual 
characters. The lower appendage of the claws is less incurved than 
usual, reaching the form seen in difficilis. Should the form of claws 
induce one to place it elsewhere, it would be placed in the series near 
muticus, from any of which it will be known by the acute prosternum.

A. iiiacer Lee. — Elongate, cupreo-aeneous, feebly shining. Antennae piceous, 
with brassy lustre, nearly reaching the middle of the thorax, serrate from the 
fourth joint; front flat, or slightly concave; occiput feebly impressed, the line 
extending to the middle of the front, surface rather uneven, densely coarsely 
punctate, slightly strigose on the occiput, a well marked transverse ridge at the 
base of the clypeus. Thorax nearly a third wider than long, very slightly nar- 
rowed at base, sides feebly arcuate, margin slightly sinuate, hind angles rectan- 
gular, the carina well marked and directed internally, disc convex, a vague me- 
dian depression near the base, lateral depression broad, but not deep ; surface not 
deeply transversely strigose, punctate between the strig*, near the sides and 
front angles more densely strigoso-punctate ; elytra narrowed from the base with 
a very feeble post-median broadening, the ajiices rounded, rather strongly ser- 
rate, disc with a well marked costa extending from the humeri nearly to apex, 
the interval quite flat, the sutural border elevated slightly from apex, two-
