NOTES. 



Note 1. — Pseudoperla ; Mr. MacGillivray proposes this genus for 

 those species of Perla with but two ocelli. 



Note 2. — Echmepteryx agilis is, I think, identical with ^4.. hageni 

 Pack. I use the genus Amphieiitomiim, as Hagen saw Packard's 

 specimen and said they belonged to this genus ; therefore, I consider 

 Echmepteryx unnecessary. 



Note 3. — Psocus canadensis Prov. is probably P. purus Walsh. 



Note 4. — Eaton has given new names to several of our Ephemerids 

 without, I think, just cause; they are as follows : Hexagenia varia- 

 bilis, Ephemera varia, Hejytagenia hageni, H. jejuna, Leptophlehia 

 viemorialis, Ephemerella walkeri, Bcetis hageni and Callibcetis hageni. 



Note 5. — I have united several of Eaton's genera to Siphlvrus and 

 Heptagenia. Ameletus and Chironetes equal Siphlurus ; Rithogenia, 

 Ecdyrus, Iron, Cinygrna, all equal Heptagenia. 



Note 6. — Lestes stulta is perhaps a race of L. forcipata; and L. 

 vidua of L. congener. 



Note 7. — De Selys considers Enallagma (innexa, boreale and robnsta 

 races of the European E. cyathigerum. 



Note 8. — De Selys puts JE. heros in a separate genus, Epiceschia, 

 as the eyes touch only at one point. 



Note 9. — I unite Plathemis to Libellula. Kirby has recently di- 

 vided Libellula into various genera. 



Note 10. — Libellula incesta and axillena are probably varieties of 

 L. lydia. 



Note 11. — I have united Leucorrhina to Diplax. In some speci- 

 mens of D. intacta the sectors of the arculus are not stalked ; usually, 

 however, they are pedicellate. 



Note 12. — Diplax imbuta may be a discolored specimen of Meso- 

 themis simplicollis. I have seen a specimen of the latter species with a 

 red thorax and abdomen with the last few segments marked with black.
