31. Gomphus spiniceps Walsh. 



Allegheny River, Alleghany County, July 4, 1899, males 

 and females were emerging in numbers. 



32. Gomphas parvnlns Selys. 



Allegheny River, Alleghany County, May 13, 1899, and 

 June 10, 1900, a single male on each date (J. h. Graf). 



33. Gomphus albistylus Hagen. 



L^ehigh Gap, June 30, 1897, one female (iesfe Calvert); Idle- 

 wild, May 30, 1899, one female; Ohio Pyle, June 24, 1900; 

 Rockwood, June 29, 1900. I follow Dr. Calvert and Professor 

 Harvey in regarding G. naevms Hagen as a synonym of G. 

 albistylus Hagen. I have a male from Professor Harvey which 

 is identical with the Pennsylvania species. 



34 Gomphas brevis Hagen. 



Ohio Pyle, June 24, 25 and 27, 1900; Rockwood, June 29, 

 1900 ; Confluence, June 30, 1900. During a week's collecting 

 in June about Ohio Pyle this seemed to be the most abundant 

 Gomphine. It is not infrequently met with in some sheltered, 

 bush-skirted meadow, attracted there probably from its native 

 ripples by the wealth of insect prey which the more retired 

 retreat harbors. 



35. Gomphus viridifrons Hine. 



Ohio Pyle, June 25, 1900, two males; June 28, 1900, one 

 female ; Ohio River, May 3, 1899, a single teneral female. 



[A drawing — plate 3, fig. i accompanying this paper— made by Mr. 

 Williamson before those of Mr. Hine in the Ohio Naturalist, vol i, pi. 5, 

 were published, shows the tips of the vulvar lamina to extend slightly be- 

 yond the hind margin of IX, while in Mr. Hines' figures the tips do not 

 reach as far as that hind margin. — P. P. Calvekt.] 



36. Gomphus vastus Walsh. 



Beaver County, May 25, 1899; Alleghany Coimty, May, 

 June and July (J. ly. Graf and D. A. Atkinson). 



37. Gomphus fraternus Say. 



Alleghany County, May (R. F. Foerster and J. L. Graf); 

 Ohio Pyle, June 28, 1900, a female, taken while eating a mature 

 male of Argia piitrida.
