Additional Notes on some North American Odonata. 



BY PHILIP P. CALVERT. 



On Jan. 28, 1890, were published the separate copies of my 

 paper entitled, "Notes on some North American Odonata, with 

 descriptions of three new species (Trans. Amer. Ent. Soc. xvii, 

 pp. 33 — 40, I pi.)." During the next two days I sent copies of 

 my paper to various students of the Odonata. One of the new 

 species I described under the name of Leucorhinia Hageni, fig- 

 uring the inferior appendage and hamule of the male, and the 

 vulvar lamina of the female. Under date of Feb. 2, 1890, Dr. 

 Hagen wrote to me acknowledging the receipt of my paper, and 

 stated that " your Hageiii is, I believe, L. hudsonica Selys. " He 

 also sent me drawings of the male hamule and female valvules of 

 hudso7iica. I can now see no reason for believing Hageni to be 

 specifically distinct. 



Since the publication of my paper, Mr. Charles W. Johnson 

 has kindly looked over my Floridan types of Lepthemis gravida. 

 He tells me that he has collected this species flying over the salt 

 marshes near St. Augustine, Fla. In the habitat given originally 

 (1. c. p. 36) for this species, I have misspelled Ponto Rasso for 

 Punta Rassa. 



Students of the Odonata must rejoice in the recent publication 

 of tw'o parts of Dr. Hagen' s new " Synopsis of the Odonata of 

 North America," published in "Psyche" vol. v, Nos. 160 and 

 166, and dealing with the genera Calopteryx and Anax. I have 

 recently compared the specimens of Calopteryx in my collection 

 and that of the American Entomological Society, with Dr. Hagen's 

 paper on that genus. In both collections Calopteryx is but poorly 

 represented, and but few new facts were ascertained from the 

 comparison.
