SMICRONYX WEEVILS—-ANDERSON 331 
Brotoay: The only biological information available on this species 
is this host record: ‘On Helianthus giganteus,’’ Vienna, Va., June 26 
(USNM). 
Discussion: The single female specimen from which Blatchley (in 
Blatchley and Leng, 1916) described S. pingus is slightly smaller than 
average, but agrees very well otherwise with the rest of the material 
examined. 
This species closely resembles S. constrictus (Say), but may be dis- 
tinguished from that species by the linear scales of the prothoracic 
disk, two sizes and colors of elytral scales, and reddish brown tarsi of 
S. pinguis, as opposed to oval scales on prothoracic disk, uniform size 
and color of the elytral scales, and black tarsi of S. constrictus. In S. 
pinguis, the internal sac of the male genitalia is covered with large 
spines, and this is not true of S. constrictus. 
DistripuTtion: Present records indicate that the range of S. 
pinguis extends across the approximate middle of the Atlantic coastal 
plain, the Appalachian highlands, and the interior plains region. The 
following specimens were examined: 
INDIANA: CRAWFORD Co.: July 14 (CNHM). 
KANSAS: POTTAWATOMIE CO.: Onaga (USNM). 
MISSOURI: ST. LOUIS Co.: St. Louis (CNC). 
OHIO: PIKE Co.: July 31 (ELS). 
PENNSYLVANIA: ALLEGHENY Co.: Pittsburgh, June 11, July 4, 20, 22 (CM). 
VIRGINIA: FAIRFAX Co.: Vienna, June 26 (USNM). 
Total specimens examined: 26.

Female, ‘‘ Nebr.,’? CM (Ulke collection). 
Description: Body and legs piceous throughout. Rostrum sub- 
glabrous and deeply punctate before antennal insertions in male; 
finely and sparsely punctate in female; closely squamose behind 
antennal insertions in both sexes. Head finely alutaceous, sparsely 
punctate in front. Antennal club shining, usually glabrous at base. 
Prothorax broadly rounded at sides, slightly narrowed toward apex; 
punctures shallow and rounded, becoming more distant toward mid- 
dle of disk; smooth, median line present for over half distance from 
apex to base; scales small, oval, very light gray, becoming sparse to- 
ward the middle of disk; prosternum deeply emarginate, transversely 
impressed. 
Elytral intervals thinly covered with small oval gray scales. Under- 
side of thorax and abdomen sparsely covered with broadly oval light 
gray scales. Femora strongly clavate, sparsely covered with elongate
