Note. — This rare species was first described by Holmgeen (5) 

 from soldiers and workers, as the second species of the genus, 

 the first being Ho doter mopsis sjostedti Holmgeen from Tonkin. 

 The specimens on which his description was based were found by 

 Prof. Watasé, Messrs. Kuwano arid Namiye in a decayed tree on 

 a Mil near Naze, Amami-Öshima. The species has not as yet 

 been caught from any other locality. An account of this island 

 from the zoo -geographical point of view, is given by Prof. Watasé 

 in a foot note to Holmgeen's paper (5, p. 109).
