We have in Japan the following 3 species: 



1. Stigma of the fore -wing ends far before die apex &nd the 

 prolongation of the 2nd oblique of the hind wing not meet 

 with the first oblique * * 2 



- Stigma of the fore wing ends near the apex and the prolong- 

 ation of the 2nd oblique meets with the first oblique 



• • intermedia Mats. 



2. Larger species; stigma of the fore-wing ends indistinctly in a 

 very acute point * miyabei Mats. 



- Smaller species; stigma of the fore-wing ends distinctly and 

 obliquely truncated • • • • m imifushi Mats, 



1. Schlechtendalia miyabei n. sp. (Pl.X.f. % a, b; pi. IV, f. 1).

 globose, the first joint near the tip with a round sensorium, the 3rd, 

 4th and 5th with- irregular, differently shaped sensoria, some being 

 oblong, oval and some rhomboidal, the 3rd on the surface with about 

 17, the 4th about 6, the 5th about 15 sensoria, and the peripheries 

 of the sensoria are not distinct; the 3rd more than twice as long as the 

 4th, the 5th somewhat shorter than the 3rd, anterhinarial very short 

 and of a half breadth of the postrhinarial; fore- wings with long, sickle- 

 shaped stigmata, sending the stigmatic nervure rather from near the 

 base, 3rd oblique distinctly shorter than the stigmatic nervure, the 

 space between the 3rd and 2nd obliques much narrower than the space
