GENUS VILERNA, STAL. 



" V. rugulosa Stal. This insect seems to be widely distributed 

 over all northern Argentina where it occurs abundantly 

 among the different kinds of yuccas and their allies. A 

 favorite retreat of its seems to be between the bases of these 

 spined leaves and the stem to which they are attached.
