 A Strong flying species, frequenting rapid streams. Transforms in mid- 

 summer, and appears in flight and ovipositing late in the summer or 

 early in autumn. " Observed flying late in the afternoon, and oviposit- 

 ing in a small brook that was rippling over pebbles." Kellicott {Joe. cit.) 

 The species has not been recorded from this state hitherto, but there are 

 New York specimens in the Museum of comparative zoology, and the 

 species has long been known from Illinois and Massachusetts.

This is a common species in the northeastern United States, ranging 

 from Illinois eastward ; it is more generally distributed throughout its 

 range than are most gomphines. Next to G. exilis it was the com- 

 monest Gomphus at Saranac Enn, where it frequented all sorts of waters. 

 Imagos were common during the latter part of June and the first two 

 weeks of July along the wagon road and railroad between Little Clear 

 and Big Clear creeks ; they were foraging there, and, while a little shy 

 and wary, were not very difficult to catch with a net. 



Nymph. Total length 31 mm ; abdomen 20 mm ; hind femur 6.2 mm ; 

 widtn of head 5 mm, of abdomen 7 mm. 



Body elongate, somewhat depressed ; abdomen lanceolate, pointed. 



Color dark brownish, with some black marks on the sides of the 

 thorax; margins of the abdominal segments darker; a pair of black dots 

 on the dorsum of each of the middle abdominal segments.
