This species is likely to be found more generally distributed through 

 the central part and in the higher altitudes of New York state than the 

 preceding one. It flies throughout the greater part of the season. Pairs 

 are often seen coursing the borders of ponds and ovipositing in early 

 spring, and in August males are often seen out on the uplands, miles 

 from water, foraging. They are exceedingly difficult to capture ; but the 

 nymphs are often found quite abundantly and are easily reared. 



Nymph. Measures in total length 24 mm ; abdomen 14 mm ; hind 

 femur 7.5 mm; width of head 7.5 mm, of abdomen 9 mm. 



Characters as stated for the genus : there is a middorsal paler line on 

 the abdomen, distinguishable among the other paler markings ; there is a 

 little proximal seta on the lateral labial lobe added to the 10 that are 

 always present in Carolina; the hook is very long and slender and 

 incurvate at end as in that species; the mental setae are 14-15, as in 

 that species, with the outer 8 or 9 very close set and longer.

This cosmopolitan species is apparently rare within our limits. 



Nymph. Measures"in total length 25 mm; abdomen 15 mm; hind 

 femur 7 mm; width of head 7 mm^ of abdomen 8 mm. 



Body clean, smooth, depressed, very similar to Tramea, with rows 

 of four to six black dots arranged transversely near the apex of abdominal 

 segments 5-8, paired blotches at the middle of the sides of segment 7, 

 at the lateral margins of segment 8, and near the middorsal Hne of
