 wings ; of the female darker and equal to or a little longer than the wings.

 of male with the apex obtuse, a little compressed, the sub-basal tooth 

 rather slender. Ovipositor less curved than that of 0. vulgare and with a 

 very sharp point. 



Measurements : Male— Length of body, 18 mm.; of pronotum, 5.5 mm.; 

 of tegmina, 21 mm.; of hind femora, 16 mm. Female— Length of body,
