THE GEOMETRID GENUS BARN ESI A. 



In 1 910 Mr. Grossbeck proposed the name Barnesia for a 

 species from Arizona (Journal N. Y. Ent. Soc, p. 207). It now 

 appears that Barnesia was used as early as 1901 (Ann. Cient. 

 Paraguay) by Bertoni for a supposed new genus of Dendro- 

 colaptid birds. The moth may take the name Eubarnesia nov. 

 nom., type Eubarnesia ritaria Grossb.
