basal pale band on II, may be some apical 
pale scaling on I; mid tarsus with small basal 
bands on I-IV and apical pale scaling on 
I-II. Tarsal claws equal, fore and mid each 
unidentate. Tergites II-VI and VIII with 
basal bands, VII with a baso-lateral white 
patch, and sometimes a small medio-basal 
spot. 
The series of specimens from Mindoro and 
Jolo differ slightly from the Samar series in 
having hind tarsal segment IV all white 
dorsally (was very narrowly interrupted on 
two specimens). Also, the subbasal white 
patch on costa is frequently obsolete dorsally 
or reduced to a line of scales on the anterior 
margin only.
