tion, the species is more conspicuous than most others. Then, too, 

 both sexes, but especially the male, are inquisitive, and perch on 

 the very tops of the rushes to watch the intruder. If disturbed 

 they return again and again to the same spot. This species is also 

 less dependent on the weather than most others and may be seen 

 flying about on cloudy days, during a high wind, or even in a driz- 

 zling rain. 



The nymphs of this species are broad and flattened, with the 

 lateral margins of the last two segments conspicuously serrate. 

 They prefer a stump, a board, or the post of a wharf for their 

 final transformation and the dried nymph skins may be found in 

 such localities and often on the inside of boathouses. 



Adults of both sexes were taken at Lake Maxinkuckee, Lost 

 Lake, Bass Lake, Twin Lakes, Yellow River and Hawk's marsh. 



A pair of this species which had been brushed into the water 

 was immediately seized and swallowed by a large bass, probably 

 Micropterus sahnoides. 



5. CELITHEMIS ELISA (Hagen) 



Not as common as the preceding species and considerably 

 smaller. In the coloration the red is more prominent, particularly 

 toward the tip of the wings. The sexes do not fly about together 

 as does C. eponina; the female keeps well out of sight among the 

 rushes and dense vegetation back from the water's edge. 



The male, however, perches on the tips of the rushes and is 

 nearly as inquisitive and conspicuous as the preceding species. 



The nymphs are similar to C. eponina but smaller, and they 

 prefer a rush stem for their final transformation, and the dried 

 nymph skins are found in such places. 



Adults were obtained at Lake Maxinkuckee, Lost Lake, and 

 Bass Lake ; the nymphs were obtained from Lost Lake. 



6. CELITHEMIS FASCIATA Kirby 



A rare species only seen once during the entire summer. . It 

 can be distinguished at once from the two other species of the genus 

 by its color, the general tone and the spots on the wings being black 

 rather than reddish brown. It is about the size of elisa and re- 

 sembles it in its habits, the female remaining hidden among the 

 vegetation along shore, while the male roams about in the rushes 

 over the water. 



About a dozen specimens were obtained at Twin Lakes on 

 August 31, and they were the only ones seen.
