Approximately the number of species of Formosan Rhopalocera 

 recorded up to the present date stands as follows : 



Recorded up to 1907 in the lists 



A month spent at Mount Ari (Arisan) during August, 1908, in 

 investigating the lepidopterous fauna of Formosa has enabled me to 

 make several interesting additions to the Rhopalocera. Here I dis- 

 covered Grapta c-album Linn., Vanessa xanthopsias Esper, and 

 Argynnis paphia Linn., at an altitude of 7,300 feet ; probably this 

 is the most southern limit of these species in the Oriental or Indo- 

 Malayan region, to which Formosa belongs unless they should 

 eventually be taken in- some of the high mountains of the Philippine 

 Islands farther south.
