(ORDER ODONATA.) 



By E. B. Williamson. 

 According to Banks' Catalogue one species of Odonata, 

 Libellula qiiadrimaadata Linne, has been reported for Wyo- 

 ming. Thirteen other species have been recorded for the Yel- 

 lowstone. From July 19 till August 6, 1899, the writer, a 

 member of the Wyoming Fossil Fields Expedition, observed 

 the species considered below. Others were seen but not taken. 

 Doubtless Wyoming will be found to be less favored odonato- 

 logically than many of the other States ; the number of species 

 to be recorded will be small when compared with the number 

 now known to live in New York, Pennsylvania, Georgia, Ohio, 

 and other localities. 



I. Lestes unguiculatas Hagen. 



lyaramie, July 19; Medicine Bow, July 20; Sheep Creek, 

 Albany Co., July 23; Little Medicine, Carbon Co., July 30. 

 A common species at all points. The males have the superior 

 appendages at base dorsally and externally more or less pale 

 yellow.
