104 DRAGONFLIES OF OHIO. 



The markings of the wings are like those in the male 

 but may be very much reduced, but not entirely absent. 

 An exceedingly abundant species in all sections. In 

 the marshes around Sandusky Bay it is more common 

 perhaps than any other dragonfly during July. Pairs 

 in copulation were taken July 18, 1896. 



Celethemis elisa, Hagen. 



Length: of abdomen tf 20-22, 9 19-20; hind wing 

 c? 27, 9 25. 



Colors: male, red, black and yellowish, front red; 

 fore wings hyaline, base yellowish a point above the 

 triangle, a spot beyond the nodus, and apex reddish 

 brown; most of the cross veins along the costal 

 margin, margined with brown, pterostigma yellowish 

 to red. 



Hind wings hyaline, with an elongated, irregular 

 patch extending from base of wing to beyond the outer 

 part of the triangle, a large patch below this not quite 

 reaching the posterior or anal margin, a patch beyond 

 nodus, and apex, reddish brown ; the basal foruth of the 

 wing where not occupied by brown is yellowish, pteros- 

 tigma and cross veins as in the fore wings. Abdomen 

 black, superior parts of 3-7, except apex, red. 



In the female the front is yellowish, the color at the 

 base of the hind wings is clearer than in the other sex, 

 and abdominal segments 2-7 are yellow superiorly; 

 otherwise like the male. 



The form is very common in northern Ohio and has 

 been taken in the southern part of the state. Differing 

 from the preceding species, the females are taken much 

 less commonly than the males.
