REPORT OF THE 



It was to be seen during the greater part of the summer on sunshiny days coursing 

 up and down Little Clear Creek on the hatchery grounds. It was observed 

 nowhere else, and it has not been hitherto reported from New York State. 



Didyniops transversa Say. This form was not very common at Saranac Inn, but 

 nymphs, plate 3, figure 9, were taken in the borders of Little Clear Pond and Creek, 

 and exuviae were found along the eastern shore of Lake Clear, hung up in the bushes 

 or attached to large logs several yards from the water's edge. 



Epicordulia princeps Hagen. This species was seen but a few times at Saranac 

 Inn, and no specimens were taken either as nymphs or images. It is not uncom- 

 mon in other places in the State, and will probably be found quite generally dis- 

 tributed when proper search is made for it.

Tetragonenra. Four species of this genus were all common at Saranac Inn, 

 and Dr. Needham found eggs laid in strings, which probably belong to this genus. 

 They were attached together in masses and hung on partly submerged twigs at the 

 surface of the water, and were very common objects about the shores of Little Clear 

 Pond. While their identity cannot be absolutely proven it is very probably as stated. 



Tetragonenra spinigera Selys. This dragon fly was exceedingly abundant at 

 Saranac Inn during the month of June, flying about the hatchery grounds in com- 

 mon with the other species, and occurring also about every little clearing in the 

 forest. 



Tetragonenra cynosnra Say or dog-tail. This species, which has hitherto been 

 recorded from but few localities within the State, is likely to be found in most
