Dragon flies at Old Forge 

 (Odouata) 



As already remarked, the dragon fly fauna of Old Forge is 

 less abundant than that of Saranac Inn. It possesses a number 

 of interesting species, however. 



Hagenius brevistylus. This big dragon fly was frequently to 

 be seen on Moose river, by the hatchery, resting upon the pole 

 bridge [shown on pi. i] or upon boulders in the stream, or flying 

 swiftly overhead in the pursuit of prey. Repeatedly I saw one 

 sweep through the air, and capture another big species, an unde- 

 termined Gomphus, and fly with it struggling to the tree tops. 

 A moment after it had alighted there, a gomphus wing would 

 come floating down, and then three others, following. 



Gomphus sp. ( ?) This is a species just noted as being 

 captured by Hagenius. But, though Hagenius could capture 

 it with apparent ease, I could not at all. I tried repeatedly, 

 and stalked specimens with the utmost care as they rested on 

 boulders in the edge of the stream, and once I came so near 

 that I knocked a specimen into the water, but, notwithstanding 

 all m}^ efforts, I did not catch a single specimen, and so the 

 species remains undetermined. It was a big olive-green species 

 with the aspect ofG. villosipes. 



Gomphus spicatus. Cast skins of this species were sticking 

 to the piers about Old Forge pond on June 20th, and a single 

 live nymph was taken from the mud with the sieve net. Nu- 

 merous species were seen along the road to Bald IMountain 

 pond on the 2d of July. 



Gomphus ventrieosus. I was delighted to be able to capture 

 at the road crossing Beaver Meadow brook the only specimen 

 that I have ever seen alive. It was darting in and out among 

 the shrubbery, apparently chasing midges, when I succeeded 

 in landing it in my net. This was the first record of its 

 occurrence within New York State. I searched dihgently all 

 about the brook for nymphs and for cast skins, but did not 

 find any. 



Dromogomphus spinosus. Several specimens of this hand- 

 some species were seen resting on the elder bushes by the road 

 near Old Forge pond. 



Cordulegaster sp. (?) Young nymphs were found in Bald 

 Mountain pond on July 2d, and in Beaver Meadow brook on 

 June 21 st, but no adults belonging to this genus were observed 

 during the season.
