97. Celithemis fasciata, Kirby. Cincinnati by- 

 Charles Dur}'. Its hitherto recorded range is " Can. 

 Ga., Fla," In August 1896, Mr. E. B. Williamson 

 took it in Eastern Indiana; these captures indicate a 

 wide distribution through the interior. 



In 1896 dragonflies were very abundant in the in- 

 terior of the state ; hitherto rare species were taken 

 frequently and probably a few, for example, Tramea 

 ounsta, came teraporarially into our area from the 

 south and may not again occur until simillar con- 

 ditions prevail,— an open winter with summer temper- 

 ature from early in April. In 1897 conditions were 

 very different ; the spring weather was unusually cold 

 and summer temperature long delayed. Odonata were 

 far from abundant; species usually common were not 

 seen at all or by single individuals at long intervals ; 

 for example, Tramea lacerata, and T. Carolina were 

 scarcely noticed during the entire early summer. 

 Carolina was not seen at all by the writer, and only 

 an occasional lacerata until September 10, at Licking 

 Reservoir, where it w^as found issuing from the pupa 

 stage in large numbers. Should the local species of 

 Tramea occur in abundance in 1898 certain inferences 

 from that and the observed facts would appear to be 

 safe : 1. Tramea ordinarily requires two years to reach 

 maturity, 2, but unusual seasons may abridge or ex- 

 tend this period.
