with black. In shape like those of hageni Walsh, but with the superiors 

 shorter and the extremities more upturned, as shown in the accompanying 

 figures. 



f. HAGENI 



£J?£CURV/\TUM 



Female. — Head and prothorax colored as in the male, abdomen pale be- 

 neath with dorsum black with indications of basal rings, the black on the 

 eighth segment becoming more or less of an apical spot. No constant differ- 

 ences have been discovered between the females of this species and hageni. 

 Abdomen, male, 22 mm.; female, 21 mm. Hind wing, male, 15 mm.; female, 

 16 mm. 



The type male is from Wyandanch, Long Island, N. Y., July i, 

 1910, and the female from Lakehurst, N. J., June, 1898, when a pair 

 were taken in copulation. Nine male paratypes and one female are 

 from Wyandanch, and three males from Lakehurst collected in May 

 and June. 



The species is most nearly related to Enallagma hageni, being col- 

 ored about as in that insect, but may be readily told from it by the 

 shorter superior appendages of the male. Some of the male para- 

 types are without the linear spot on each side of segment eight. 

 The species has been named recurvatum on account of the character 

 of the male superior appendages. Mr. E. B. Williamson, Dr. Philip 

 P. Calvert and Prof. Albert P. Morse have each examined a single 

 male of this Enallagma from Wyandanch, and Prof. Raymond C. 

 Osburn has seen the entire series. To them, and to Mr. John A. 

 Grossbeck, who made the outline sketches of the male abdominal 

 appendages, I am under obligations.
