Brotocy: A single host-plant record was taken from the material 
examined: ‘‘Reared from fruit and flower of giant ragweed,” Kinder- 
hook, Illinois, Aug. 10 (5 specimens, USNM). 
Discussion: This species is rather similar to S. tesselatus Dietz in 
general body shape and size, color of scales, and punctation of the 
prothorax. However, S. squalidus is usually distinctly larger than 
S. tesselatus, and has a rostrum which is longer, smoother, and more 
polished before the antennal insertions in the female than in the 
female of S. tesselatus. 
The type specimens of the species listed in synonymy under S. 
squalidus Casey are so similar to the type of the latter that it is 
difficult not to consider them all conspecific. 
Distripution: Records taken from the material examined indicate 
that the range of S. squalidus extends from the Atlantic coastal 
plain across the Appalachian highlands, the central lowlands and the 
Great Plains to the southern Rocky Mountains. The following 
specimens were examined:
