SMICRONYX WEEVILS—-ANDERSON 317 
A single host-plant record was taken from the material examined: 
“On Coreopsis tripteris L.,’’ Shawnee State Forest, Ohio, Sept. 2 (ELS). 
Discussion: A comparison of the lectotype specimens of S. griseus 
LeConte and S. picipes Dietz did not reveal any differences that could 
not be attributed to individual variation. In the lectotype of S. 
picipes Dietz, the brown scales of the elytra are arranged in a more dif- 
fuse median stripe than in the lectotype of S. griseus. However, some 
specimens of S. griseus have been seen to have a less well-defined 
sutural stripe than others, and it does not seem unlikely that the stripe 
could be rather diffuse and poorly defined in some specimens. 
S. griseus is similar to S. pleuralis Dietz in body shape, color pattern, 
and genitalia, but the unequal claws, and suddenly narrowed pro- 
thorax of S. pleuralis will serve to distinguish the two species. In 
addition, when the two species are actually compared, it can be seen 
that the brown sutural stripe on the elytra is broader and the rostrum 
of the male more strongly curved in S. pleuwralis than in S. griseus. 
DistriBuTION: S. griseus has been recorded from the Atlantic 
coastal plain in Maryland and Virginia, the Appalachian highlands, 
the eastern portion of the central lowlands, and the Gulf coastal plain 
in Mississippi. The following specimens were examined: 
Ouro: Lucas co.: Adams Township, July 15 (USNM). scroro co.: Shawnee 
State Forest, Sept. 2 (ELS). 
PENNSYLVANIA: ALLEGHENY Co.: Wall, July (CM). 
MARYLAND: MONTGOMERY Co.: Glen Echo, Summer (USNM). 
MISSISSIPPI: GEORGE Co.: Lucedale, June 3, 8, 20, 22 (CU). 
NortH CAROLINA: BUNCOMBE Co.: Valley of the Black Mountains, July 5-7 
(AMNBA). rraNsyLvania co.: Lake Toxaway (AMNH). 
VIRGINIA: NORFOLK Co.: June (CM). 
Total specimens examined: 27.

Description: Rostra of both sexes black to piceous; moderately 
curved in male, slightly so in female; sparsely punctate, rugulose, 
unicarinate, thinly squamose behind antennal insertions; deeply 
punctate and rugulose before antennal insertions in male; shining, 
punctate, not rugulose in female. Head black to piceous, closely 
squamose above base of rostrum. Antennae black, their scales pale 
brown, second funicular segment distinctly longer than third. Pro- 
thorax black, broadly rounded at sides, suddenly narrowed and 
slightly constricted near apex; disk evenly covered with subangular 
punctures; scales ovate, light brown on disk, pale silvery gray at sides;
