a SMICRONYX WEEVILS—ANDERSON 309 
Broutoey: A single host-plant record was taken from the material 
examined: ‘Sweeping Ambrosia,” 7 miles north of McAllen, Texas, 
Sept. 20 (B. D. Valentine). 
Discussion: The lectotype of S. impressirostris Dietz is evidently 
a specimen of S. tesselatus Dietz, but it has a more accentuated pre- 
basal impression than do most specimens of the latter species. The 
rostrum is slightly impressed before the base in all specimens of S. 
tesselatus, and it seems probable that the impression could be more 
marked in some specimens. The figure of the rostrum of S. wmpres- 
sirostris given by Dietz (1894) evidently exaggerates the impression, 
if it was taken from the two specimens he mentioned in his description 
of that species. 
DistrrisutTion: Present records indicate that S. tesselatus is widely 
distributed in the central lowlands and Appalachian highlands, and 
may be found on the Atlantic coastal plain in Maryland and Virginia.
