Ehrhornia cupressi (Ehrh.) 

 1911. Spharococciis cupressi Ehrhorn, Can. Ent., vol 43, p. 

 277, figs. 3, 3 a, b, c. 



This species will be redescribed at length in a forthcoming 

 paper by Mr. F. B. Herbert, of the Bureau of Entomology, and I 

 shall merely note that the original description is in error in regard 

 to the statement that the anal ring is hairless. The anal ring has 

 six small setae.
