Two examples from Costa Eica (Palo Verde, 5250 feet, and 
Volkan Irazu, 4000 feet) show that trichogramma Wals. is a 
synonym of this. The white posterior marking of first segment 
varies in development, hut is always present; a white spot or 
fasciate marking in disc towards cleft is also sometimes shown. 
The expanse varies greatly, the largest specimen being 25 mm.
