(3\ Differs from P. ingeniosus in that the two oblique fuscous streaks 

 on the anterior wings are connected by a straight streak situated two cells 

 below the anterior fork of the cubitus, thus fanning a single, doubly Vmu^ 

 ate line. In alt other respects the description of the latter species seems 

 to apply equally well to this.
