Tabanus yokoamensis, Bigot, might possibly be a denuded spe- 

 cies of the mandarinuS) as one denuded from Akita (August 1 5th, 

 1913) agreeing with Bigot's description is quite identical with the latter 

 species, and I have found that two materials of mandarinus have a 

 very mediocre development of the ocelligerous tubercle.
