 (Plate IX, fig. 3.) 



Podisma primnoa FISCHER DE WALDHEIM, Orth. Russ. (1846), p. 248. 

 Primnoa viridis MOTSCHULSKY, MS., ibid. 



On account of the extraordinary development of the subgenital plate 

 of the male of this largest of Podismae, I have proposed for it the sub- 

 generic name of Eupodisma. 



Fischer deWaldheiin describes it from Verkhni-Udiusk,Transbaicalia, 

 Siberia. Specimens in my collection were collected by Parschine at 

 the same place in June, at Samonoffsk in June, at Khabarowki and 

 Tscherhjava on the Amur in May and August, and in the Desert of 

 Khorinskaya in Trausbuicalia.

 together. Pronotum long, compressed, subequal, narrowed above
