This seems to be an abundant species in Japan, where it 

 represents the darkest form of the species, and I possess a long 

 series collected by Mr. Lewis in that country. In Japanese 

 examples the black apical spot to the tegmina is either very 

 obsolete or entirely absent. The type of It. similata, Melich., is 

 in my own collection. The very pale form (var. b) is from the 

 Nicobars.
