S. I. KUWANA. 



Note : — Prof. E. E. Green, Way's end, Camberlcy in Surrey, to whom- 

 I have shown specimens of this species, has kindly supplied me with the 

 following remark : " I have compared your specimens with typical 

 examples of both longivalvata and P. pyriformis. Your insect appears 

 to take a place intermediate between these two species. I note the 

 following characters that serve to distinguish the Japanese form: — -The 

 antenna: are much longer than in either. Eimbs approximately same size 

 as P. longivalvata Green, but rather longer than those of P. pyriformis 

 Ckll. Stigmatic spines smaller than those of P. longivalvata, but consi- 

 derably larger than those of P. pyrifontiis. Marginal hairs very long and 

 stout, much larger than those of either of the other two species. Anal 

 operculum shorter than that of P. longivalvata, but longer than that of P. 

 pyriformis."
