1^ There is a strong probability that the original specimens of this species 

 were collected by Zimmermann, who was working in South Carolina at that 

 time and regularly sending material to Europe. As we have already shown 

 (Trans. Amer. Entom. Soc, xli, p. 34, (1915)), until 1838 Zimmermann's work 

 in the state was probably all done in the vicinity of Georgetown, which is 

 doubtless the type locality of the present species. In the ab.sencc, however, 

 of a positive statement by Burmeister as to the collector we would hardly be 

 justified in positively fixing this matter. The specimens were, according to 

 Burmeister, in Germar's collection, and the collector's name probably had 

 not been preserved. In the case of material belonging to himself and collected 

 by Zimmermann, Burrneister carefully credited it to the collector.
