with a heavy dotted and banded pattern as follows :—a 
broad band at the cord and another at the origin of the sector 
extending across the wing to the margin, ending at the tip 
of 2nd A; this pattern does not include the costal cell ; the 
band at the cord is forked at its cephalic end, one branch 
encircling Sc,, the other the tip of Sc, and &,; these 
bands are pale brown, broadly margined with dark brown,
