The insect lives on Thespesia populnea (L.) Sal. (Malvacez), 
causing irregular depressions and wrinkles in the leaf lamina. 
Evidence of the work and of the presence of the preadult stages 
is noted throughout the year in the locality cited, but the adults 
seem to appear only in certain months.

of the subfamily Liviine has never been recorded from the Phil- 
ippines before.
