under nasutus would follow. There appears to be no other safe 

 criterion for separating these species as here recognized.

These specimens agree closely with ■ those here recorded as 

 E. pallidus (Redtenbacher), except in having a noticeably heavier, 

 longer and more truncate fastigium of the vertex, while the ovi- 

 positor averages shorter. 



Length of body d" 36.8, 9 37 to 40.8; length of fastigium of

The insect which we recognize as this species is intermediate in 

 form of fastigium of vertex between E. varius (Walker) and E. so- 

 brinus (Bolivar) ; this process averages proportionately longer than 

 in varius but not as elongate nor as acute as in sobi-inus. 



In the present material the tegminal costal margins are immacu- 

 late or faintly margined with brown. This feature is clearly 

 valueless as a specific factor in gracilis, except that it may be said 

 that these margins are sometimes embrowned in the present insect, 

 while in other species such coloration never occurs.
