Type, E. semilutea, Walk. 



I did not examine AValker's genus when working out the 

 Central-American specimens, as that writer gave the locality 

 for his typical species as " Hindostan," whereas I tind it is 

 distinctly localized as " Para." Dr. Handlirsch having kindly 

 allowed rae to examine the type of StaPs genus Rhonicia, I 

 find it congeneric with Walker's Echetra, and Stal was 

 probably similarly misled by Walker's erroneous habitat.
