SMICRONYX WEEVILS—ANDERSON 233 
Bronocy: The host-plant records which follow were taken from the 
material examined: “‘Bred Vachellia farinosa,” Victoria, Tex., March 
17 (USNM); “‘on cotton,” Lawrence Co., Tenn., June 25 (USNM); 
“cotton,” Tallulah, La., July 23, (USNM). 
Discussion: After examining the material determined by W. G. 
Dietz in the Dietz collection at the Museum of Comparative Zoology 
(Cambridge, Mass.), the writer has concluded that Dietz (1894) 
applied the name S. vestitus to the same species he described as S. 
commiztus in 1894, and not to the species described as S. vestitus by 
J. L. LeConte in 1876. Blatchley and Leng (1916) evidently applied 
the name S. vestitus to the correct species, because they stated that 
they had examined the type specimen, and their description of the 
type has proved to be quite accurate. 
Distrrisution: Records from the material examined indicate that 
S. vestitus may be found in both the eastern and western portions of 
the Gulf Coastal Plain, in the central lowlands region, and in the 
southern Appalachian highlands. The following specimens were 
examined: 
ALABAMA: TUSCALOOSA CO.: Tuscaloosa, May 23 and 24, June 18, July 7 
(B. D. Valentine). 
ARKANSAS: WASHINGTON co.: June 4 (ELS). 
LOUISIANA: MADISON PARISH: July 23 (USNM). 
TENNESSEE: KNOX CO.: Knoxville, May 17, 18, 22, 29, June 21, Aug. (Howden). 
LAWRENCE Co.: June 25 (USNM). 
Texas: smiTH co.: Tyler, July 7 (Howden). victoria co.: Victoria, March 
17 (USNM). 
Total specimens examined: 32,
