For the past two or three years we have been receiving odd speci- 

 mens of this species each year ; we have been unable to find any des- 

 cription that would fit it so venture to describe the species Its charac- 

 teristic olive color combined with the prominent angles in t. a. and 

 1. p. line in submedian fold should render it easily recognizable.
