 tip, with the two last joints longer and more slender than in E. wl- 

 gata, but not suddenly contracted at the base of the penultimate as 

 in E. lutea : legs blackish, a little shorter than those of E. lutea : 

 wings slightly reddish, almost hyaline ; almost all the veins bor- 

 dered with brown, with which the spots of the middle are con- 

 fluent."
