 sp., giving only a fi^tzre of an imago found in the province of 

 Satsuma. Afterwards he (3) called it under the specific name 

 Termes satsumensis, but ^he description of the species not given. 

 Later on, Yano (2, 6, 7, 8) \7I10 recorded the winged forms and also 

 the queen, soldiers, workers, nymphs and larvae from the same district, 

 called them at different times as Calotermes satsumaensis, Calotermes 

 satsumensis or Calotermes (Glyptotenves) satsumensis (Matsumura).
