ATHALIA SPINARUM JAPANENSIS, new subspecies. 



Very like the European spinarum, but may be distinguished from 

 that form by the black wings and black venation. The typical form of 

 spinarum has the lateral lobes of the mesonotum entirely black, 

 although there are occasionally specimens which have the anterior 

 part the color of the sides. All the Japanese specimens have the 

 anterior part of the lateral lobes of mesonotum the color of the sides. 

 The Japanese forms are more pubescent and duller, the saw of the 

 female is somewhat heavier in appearance; the hypopygidium of
