A SUMMARY OF THE PHILADELPHIA 

 ODONATE FAUNA. 



SCOPE OF THIS CATALOGUE. 



The species whose names are numbered in Part II have been cer- 

 tainly observed within a radius of twenty miles from the Philadelphia 

 City Hall. This arbitrary limit has been fixed by the fact that the 

 observations upon which this paper is based have been mainly con- 

 fined to the region indicated. The unnumbered species may, from 

 what is now known of their distribution, hereafter be found in this 

 district. The Odonate ftxuna of Philadelphia is, therefore, here con- 

 sidered to consist of the following species : 



Subfam. CAIjOPTEBYGIN^ (4 sp.) Subfam. AGRIONIN^ (19 species). 



1. Calopteryx maculata 5. Lestes forcipata 



2. C. dimidiata, race apicalis* 6. " rectangularis 



3. Hetserina americana 7. " inequalis 



4. " tricolor* 8. Argia putrida
