The specimens in the Brunner collection are somewhat 

 smaller than the type of Bolivar. 



It may be distinguished by the colour of the wings : it 

 falls obviously into the first division of the genus, and is 

 not likely to be confused with its allies. 



The cell on the pronotum is sometimes present, and 

 sometimes obsolete.
