of Neoneura and the flight and actions of all have been sim- 

 ilar. Their agility must be seen to be appreciated. And al- 

 most invariably they have been found about deep pools in 

 small streams with drift or overhanging bushes near at hand.

37. Gomphus graslinellus. 

 Oklahoma : Wister, June 5, i 9 . 



This specimen has been studied by Dr. Calvert and myself, 

 and it seems safe to refer it to this species. Graslinellus about 

 Bluffton, Indiana, has' been very numerous during its season 

 in past years, and, in the large number of specimens I have 

 examined, considerable variation in markings is shown. For 

 example, the black mid-dorsal thoracic stripe may be of uni- 

 form width, in which case the pale stripe on either side is 

 wider below; or the mid-dorsal stripe may be cuneiform, in 

 which case the pale stripe on either side is of uniform width. 

 The dark antehumeral and humeral stripes may be entirely 

 separated by a narrow pale stripe, or they may be partly joined 

 or entirely coalesced to form a wide dark band of nearly uni- 

 form width. There is some variation, but less in the develop- 

 ment of the 2 lateral dark stripes.
