NO. 1928. DRAGON FLIES OF THE CUMBERLAND VALLEY— WILSON. 195 



17. TRAMEA ONUSTA Linnaeus. 



A single female was captured at Fishing Creek, Kentucky, July 15. 

 Several others were seen in the vicinity, the dark bases of the pos- 

 terior wings serving to identify them when everything else in sight 

 had hyaline wings. 



18. PERITHEMIS DOMITIA (Drury). 



This tiny dragon fly was first seen on the river at Fishing Creek, 

 Pulaski County, Kentucky. Afterwards it appeared every now and 

 then all the way down the river to Clarksville, Tennessee, becoming 

 more numerous after passing the State line. 



The males were seen upon the main river, while the females were 

 on the side creeks or in the fields at some distance from the water. 



19. LEUCORmNIA INTACTA (Hagen). 



This dragon fly, familiarly known as '^Johnny White-face," was 

 found only around the fresh-water ponds or on the side creeks; there 

 were none on the river. Some of the localities where specimens were 

 taken were Fishing Creek, Greasy Creek, Indian Creek, and Cloyds 

 Landing, in Kentucky ; Koaring River, Spring Creek, and Marrow- 

 bone Creek, in Tennessee; and around the pond at Sandersville 

 Ferry, Tennessee. 



20. ERYTHEMIS SIMPLICICOLLIS (Say). 



Like the preceding, this species was found only around ponds, and 

 its presence was always indicative of a pond or swamp in the vicinity. 

 It was fairly common at Indian Creek Landing, and at that time 

 (July 17) the males had not become pruinose. 



At SandersviUe Ferry large numbers of the species were congre- 

 gated around the pond and even along the river bank for some dis- 

 tance above and below. By this time (August 17) the males had 

 become entirely pruinose. 



21. PACHYDIPLAX LONGIPENNIS (Burmeister). 



Found in considerable numbers at Jellico, Tennessee, on the Clear 

 Fork of the Cumberland River, June 28, and even at this date all 

 the males were wholly pruinose. The species was subsequently taken 

 on the Big South Fork near Burnside, at Greasy Creek, Cloyd's 

 Landing, Butler's Landing, Carthage, Nashville, and Clarksville. 



22. LIBELLULA LUCTUOSA Burmeister. 



A single male was captured and several specimens of both sexes 

 were seen at Indian Creek Landing, July 17, around the small pond. 

 The species were seen at each of the other ponds visited, but none 

 were found on the river. 



23. LffiELLULA CYANEA Fabricius. 



Two males were captured on the Clear Fork at JeUico, Tennessee, 

 June 28, and another male at the small pond at Indian Creek Land- 

 ing. Kentucky, July 17. One or two females were seen in inacces- 

 sible places where they could not be captured.
