78 DRAGONFLIES OF OHIO. 



fuscous predominates, The colors are so changed in 

 dry specimens that it is difficult to define their exact 

 outlines. Male superior appendages as long as 9 + 10. 

 From above gradually widening from base ; inner 

 border suddenly excavated near the apex ; an acute 

 spine at outer distal a,ugle ; a median, longitudinal 

 thickening traverses the whole length of each ap- 

 pendage. Inferior appendage short about one sixth as 

 long as the superiors, distal end truncate. 



The female differs in having the occiput twice 

 tuberculate posteriorly, and in not having so strong a 

 constriction at abdominal segment three. The append- 

 ages are as long as + 10, foliate, pointed at apex. 



This species has bten taken at Columbus as early 

 as March 21st, and has been observed on the wing 

 during the first days of November. It oviposits usually 

 while attended by the male. The pair may be seen 

 flying over stagnant water where sedges and the like 

 abound; at intervals they drop down and alight on 

 some object near the water's surface ; soon the female 

 may be seen with her abdomen beneath the surface of 

 the water depositing her eggs. Nymphs of various 

 sizes may be secured from ponds and ditches at most 

 any time of year.
