A List of the Dragonflics Observed in Western 



Pennsylvania. — (Plate III.) 



By E. B Williamson. 



The following list of 68 species is certainly not a complete 

 one for the region considered, but may serve as a basis for 

 further work by other collectors. The unlikelihood that the 

 writer will do any more field work in western Pennsylvania 

 justifies the publication of the following notes. I have given 

 various collectors credit for their records throughout the paper. 

 Mr. J. L. Graf, Mr. D. A. Atkinson and the writer usually 

 collected in company, and nearly all of the records to which 

 no collector is ascribed were established by this collecting party. 

 Mr. H. D. Merrick has done some collecting in Beaver County ; 

 Mr. Atkinson collected at Couneaut Lake ; the other records 

 come from Alleghany, Westmoreland, Fayette and Somerset 

 counties. Dr. Calvert writes me that Gomphus albistylus has 

 been taken at Lehigh Gap. With the exception of this record 

 and the record of Pantala Havcsceyis I have examined the speci- 

 mens in every case. The first male of Gomphus parvulus taken 

 by Mr. Graf was identified by Dr. Calvert, who has also helped 

 with the determination of Gomphus brevis.
