T. MIVAKE. 



together with P. guttata, has not been met with in the Oki Islands. The 

 larva of P. guttata feeds on rice-plant, while that of pellucida is said to 

 feed on bamboos and occasionally also on rice-plant. Both these food- 

 plants are found in the islands, and therefore it may be said that there 

 exist conditions for the existence of both the species mentioned.

One male specimen captured Aug. icth on Dangyö-yama (Dogo). 

 This is a rare insect in Japan. The occurence of the species in the 

 islands is therefore of interest.
