narrowed to and feebly constricted at the tip; surface coarsely but not densely 
punctured with a median line of coudeused pubescence; scutellum densely 
clothed with pale yellowish puhescence. Elytral stride deep with elongate and 
rather closely placed punctures; interspaces convex, moderately wide, trans- 
versely rugulose and puuctulate; pubescence fine and sparse, with very few, 
fine, blackish hairs intermixed ; underside darker, piceous, with the pubescence 
more evident. Legs ferruginous; thighs armed with a strong, single tooth. 
Long. 3.25— 3.7,'> mm ; .13— .15 inch. 
Hab. — Illinois, Pennsylvania, Maryland, Michigan. 
The apex of the fifth ventral segment in the male projects in the 
form of a small lobe, which fits into an emargination of the py- 
gidium. 
A. viilpiiill^ n. sp. — Agrees with the preceding species, hut is smaller, and 
of a reddish color; the first and second joint of the funicle are relatively shorter, 
the latter scarcely one-half as long as the former in the and still shorter in 
the 9 ■> tdie following joints are about equal in both sexes. Prothorax less than 
one-half wider than long and more rounded at the sides; the elytral interspaces 
less convex atid more finely rugulose; the underside is scarcely darker than the 
rest. Long. 2.75 mm. ; .11 inch. 
Hab . — Pennsylvania (Hazleton). 
Two males and three females were taken by myself some years 
ago by bush beating and considered as S. rubidvs Lee., from which 
it differs by its larger size, more reddish color, coarsely punctured 
and finer pubescence. 
•A. I'libidiis Lee. — Oblong oval, scarcely wider behind, testaceous, rather 
densely clothed with yellowish pubescence. Beak punctured, with a smooth 
elevated line; scrobes less deep; first tw’o joints of funicle less elongate than in 
the preceding species; second joint of funicle scarcely one-half as long as the 
first in the female ; outer joints and club piceous. Eyes very convex. Protho- 
rax scarcely one-half wider than long; sides rounded from the base and feebly 
constricted at the apex; surface densely and finely punctured, pubescence con- 
densed in the median line. Elytra less than one-third wider than the prothorax, 
not widened behind the middle; striae deep, punctured ; black hairs more abun- 
dant than in the two preceding species. Scutellum densely clothed with pale 
yellowish pubescence; .scutellar region dusky, suture dark, underside darker 
and rather densely clothed with long pubescence. Legs testaceous, thighs 
strongly toothed, the anterior pair with a welt marked additional tooth ; anterior 
tibiae curved near the base and bisinuate internally. Long. 2.2 — 2.5 mm. ; .09 — 
.10 inch. 
Hab . — District of Columbia, Maryland (Deer Park). 
Readily recognized by its pale color, small size, very convex eyes, 
and the additional cusj) of the anterior thighs. The black hairs on 
the elytra, although more abundant than in the two preceding species, 
are scarcely visible, except under a lens of considerable power.
