Aeschna sp. ( ?) Nymphs of Aeschna have already been 

 noted as occurring in the food of bullheads and sunfish in Old 

 Forge pond. They were quite common in Bald Mountain pond 

 and in Lily pond, and about every pond near Old Forge adults 

 could be. seen coursing on swift strong wing all day long the 

 summer through. 



Anax Junius. This species, so abundant through other parts 

 of the State, is not common in the Adirondacks. Two nymphs 

 were taken in Beaver Meadow brook on June 30th; no adults 

 were seen. 



Bcyeria vinosa. A single young nymph of this species was 

 taken in Moose river on the 9th of July. A few adults were 

 seen later coursing over the stream. 



Didymops transversa. Among the larger species coursing 

 about the borders of Old Forge pond, this one was conspicuous. 

 It was common through the latter part of June, and a number 

 of cast skins were seen sticking to the bushes along the bank. 



Helocordulia uhleri. This species frequented waters where the 

 banks were fringed with sphagnum. It was seen in a few places 

 up the channel from Old Forge pond, but not at the pond itself, 

 and it was not uncommon at the Twin ponds and at Bald 

 Mountain pond. 



Tetragcneuria cynosura. This species was fairly common 

 about Old Forge pond, where scattering cast skins could be 

 found along the shore, but there was no abundance of it to be 

 at all compared to the condition described at Saranac Inn in 

 Bulletin 47 of this museum. 



Cordulia shurtleffi. This handsome bronzy green species is 

 another denizen of sphagnum bordered waters, and was com- 

 mon at Twin ponds and at Bald Mountain pond. 



Lribellula basalis. This species is rare in the Adirondacks, one 

 or two specimens were seen, but not captured ; nevertheless, 

 there is no doubt about the determination. 



Libellula pulchella. Common about every pond and com- 

 monly found foraging along the roadside at considerable dis- 

 tances from water. 



Plathemis trimaculata. Another pond-loving species associ- 

 ated with the preceding. 



Leucorhinia glacialis. This species was found only at the 

 Lily pond, anil only a few specimens were seen. 



Leucorhinia frigida. This species was likewise found only 

 at Lily pond, but it was common there, and moreover it was
