This insect, (Fig. 100), is readily distinguished from the

 tum, the form of the antennas, and the venation of the teg- 

 mina, which are narrow and have many of the cellules in 

 hinder part of distal half two to four times as long as 

 wide. The antenna are unlike those of any other species of 

 this sub-famil}^ having depressed or prismatic joints, ap- 

 pearing almost ensiform next the base. Another peculiarity 

 noticable is that on the distal third of the tegmina the 

 maculation is restricted to the costal half The species
