This is an exceedingly common species over the larger part of 

 the eastern Umted States. At Ithaca it abounds everywhere. 

 At Saranac Inn I found it most common about the trashy 

 borders of the deeper ponds. I have bred the species at the fol- 

 lowing dates and places: Saranac Inn July 8, 1900, Galesburg 

 III. June 30, 1895. 



Nymph. Length 14.5mm, gills 4.5mm additional. Mental setae 

 two or three on each side; lateral setae four or five. Three 

 minute teeth preceding the normal three larger ones on the end 

 of the lateral lobe above the end hook. Gills lanceolate but not 

 very Siharply pointed, pigmented in two transverse bands and 

 along the axis and sometimes slightly around the margin.
