SMICRONYX WEEVILS—ANDERSON 307 
finely alutaceous; thinly squamose above base of rostrum. Antennae 
piceous, their scales white, second funicular segment much longer than 
third. Prothorax black, scales broadly ovate and white at sides and 
in a short basal vitta, otherwise elliptical to elongate and light brown. 
Elytra black, rather inflated near middle; intervals covered with 
broad, subquadrate to suborbicular scales, mostly white, arranged 
in irregular transverse fasciae, with a few light brown scales between 
fasciae. Underside of thorax and abdomen black, covered with sub- 
orbicular, white scales. Femora piceous, moderately clavate, covered 
with elongate-ovate white scales. Tibiae piceous, thinly covered 
with elongate white scales. Tarsi piceous, first three segments short 
and broad; fourth segment extending only slightly beyond third; 
claws connate for slightly less than half their length, slightly divergent. 
Median lobe of male genitalia elongate, subparallel at sides, internal 
sac distinctly spiculate near apical end (fig. 85). 
MeasurREMENTS: The following measurements were taken from 
7 males and 3 females from Goliad Co., Texas (USNM), 1 male and 
2 females from Victoria, Texas (USNM), 1 female from Topeka, 
Kans. (USNM), and 1 female from Riley Co., Kans. (USNM). All 
measurements are in millimeters:

Brotocy: A single host-plant record was taken from the material 
examined: “Red Clover,” Decatur, Ind. (2 specimens, USNM). 
Discussion: A direct comparison of the type specimens of S. 
ovipennis LeConte and S. setulosus Dietz revealed no differences that 
could not be attributed to individual or regional variation. The 
two names are therefore considered by the writer to be synonyms. 
DistrinutTion: Records from the material examined indicate that 
the range of S. ovipennis extends from the central lowlands westward 
across the Great Plains and to the southern Rocky Mountains. The 
following specimens were examined: 
CoLORADO: DENVER Co.: Denver, July (USNM). 
INDIANA: ADAMS CO.: Decatur (USNM). 
KANSAS: RILEY CO.: No data (USNM). sHAWNEE co.: Topeka (USNM), 
Topeka, July (USNM). 
Missouri: ‘‘ Mo.’”’ (USNM).
