 basal portion; terminal portion of uncus equally broad. Vesica with a 

 single, robust cornutus; no cuneus. 



Female. — Antrum and cervical portion of corpus bursae fused

The name Sijhacr (-\-aftena, the name of a tortricid genus) is 

 derived from the Greek a^aipa, meaning a ball or a sphere.
