taken. The males were very abundant over a meadow brook 

 in Bradley in July, when twenty- five were taken. We saw 

 two females seized by males and immediately the pairs left the 

 brook and went sailing over the field out of sight. 



The average of many Maine male specimens gives alar expanse 

 93 mm. , total lengh 70 mm. , antecubitals 19-20, postcubitals 12- 

 13. Ours are as large as Ohio specimens according to Kellicott. 

 The females from Maine are much larger than the males, viz. ; 

 alar expanse 108 mm., total length 78 mm., antecubitals 22, 

 postcubitals 14, but these are not as large as Say's specimens. 

 Possibly the cold climate may make the specimens smaller. 

 Maine specimens of C. maadatus are much smaller than in 

 Hagen's description. The females of this species are also 

 much larger than the males. 



45. Gordnlegaster diastatops Selys. 



This species, reported as scarce in a previous article, has been 

 found abundantly. It was taken in July flying with C. obliqua 

 over a brook in Bradley. 



Subfamily 5, .^chnin^e. 

 74- Epiaesciina heros Fabr. 



A single female taken July 4 at Chemo Mills, Bradley, over 

 the water (Harve}). The frons above in one specimen has not 

 a well marked black T-spot, the center above is dark, and on 

 each side of the dark area near the anterior border is a circular 

 green spot ; the vertex is black with a heart-shaped green spot 

 in the center ; the abdomen has only green, ?io blue. 

 41 Boyeria vinosa Say. 



This species was abundant in August about the dams, falls 

 and swift water on the Wissattiquoik nearly to the base of Mt. 

 Ktaadn, also on the upper of the three ponds near the South 

 Basin. It was also plentiful on Russell Stream, August 25-29, 

 1899, following the banks, minutely inspecting the indentures 

 of the shore and closely examining every old log and bush, as 

 though in quest of something. It is a busy species, flying near 

 the water and, although not wary, is rather hard to catch. The 

 males were fully ten to one female.
