THE CANADIAN ENTOMOLOGIST. 77 



These, together with those recorded and described by Calvert in his 

 recent paper on the Odonata of Philadelphia, are all the species of this 

 genus found in the northeastern part of the United States, except E. 

 traviata, Selys. This was described from Mass., I have collected a 

 specimen on Long Island, N. Y. It is hardly more than a variety of E. 

 a'spersa. The superior appendages are like E. aspersa, except the lower 

 branch is a little heavier; the black on segment two has a projection to 

 the anterior margin of the segment, and the black on segment three also 

 reaches to the anterior margin in a point ; apical half of seven, all of 

 eight and nine and all of ten, except black spot above, blue. I have also 

 taken E. divagans on Long Island.

Ophiogomphus rupinsulensis, Walsh. I took two specimens. 



Dromogomphus spinosus, Selys. One specimen in Cornell Univ. col-
