It is an interesting fact that the Indian species, Spilosmyhis 

 tuberculatus, lately found in Formosa by Petersen, 15 occurs also in Japan. 

 Osmyhis hyalinatus, common in Hokkaido and occurring also in Hondo 

 and Shikoku, has recently been recorded from Siberia by Navâs, 25 so that 

 this species may be said to have a rather wide range of distribution in the 

 northern part of eastern Asia. The following table shows the geographical 

 distribution, as far as can be ascertained, of all the species listed above.
