Kuroshima, Osumi. Types No. 95768 A. N. S. P., from No. 1546a 

 of Mr. Hirase's collection. Also Yakushima, No. 1546 of Mr. Hirase's

This form differs from Ena luchuana and E. I. oshimana by the dark 

 coloration, without light streaks, and the more pronounced granula-

 respects with those from Kuroshima.
