I formerly indicated Entechnia taurea Say as belonging to the 
Paraguayan fauna; but this determination was wrong and the 
species was Entechnia fulvifrons Smith. The same error has been 
made by A. Ducke who records FE. tawrea from Para, and also by 
E. L. Holmberg who recorded it from Argentina; in both cases the 
insect in question was E£. fulvifrons. 
[* Since this was described I have examined Smith’s type of A. vesta, and 
find that cupreola is not a variety of it, but a distinct species—T. D. A. C.]
