To the foregoing record for this species I can add that it 

 occurs sparingly at Ithaca. I have bred it repeatedly in Illinois 

 in June, and have its nj^mph also from North Carolina. 



Nymph [fig.lO]. Length 14.3mm, gills 5mm additional. Mental 

 setae three each side; laterals five, or in young nymphs four. An 

 indistinctly denticulate lobe preceding the three well defined 

 normal teeth on the end of the lateral lobe of the labium above 

 its end hook. Gills elongate lanceolate, pointed, with three 

 broad transverse well defined blackish bands connected with 

 black on the axis, the apical one broader.

Though the range of this species extends from Maine to 

 Florida and Illinois, it has not hitherto been reported from 

 New York State. Its nymph is unknown. 



Three additional species from Massachusetts, E, 1 a t e r a 1 e , 

 E, minusculum and E, p i c t u m , described by Morse in 

 Psyclie, 7:207, 274 respectively, and unknown to me, may, per- 

 haps, be counted regional.
