pero el Doctor Hagen reconocio en estas especies las descritas 

 anteriormente; pero Mr. Scudder en su Proceedings XI, 1867, 

 p. 298 establece sobre la materia algunas dudas. 



Habiendo yo redactado descripciones del colorido de especies 

 aun vivas (pues despues de ser matadas pierden mucho de su 

 hermosura), las comunique al Dr. Hagen, quien las crej^o utiles 

 para la publicacion que se efectuo en gran parte en las paginas 

 215-232 y 274-287 del tomo XXYIII [y XXIX] de Berliner 

 [error for Stettiner] Entomologische Zeitung 1867 [y 1868]. 



Para no poner en cada especie el titulo de las obras citadas, he 

 usado las abreviaturas siguientes : . . . 



The list which follows contains thirty-eight titles. The latest 

 is "Selys Longchamps Revue de Syn. Agrion"; although Gund- 

 lach does not give the date here, he correctly quotes it as 1886 

 on p. 220. The only item in this list which is unfamihar in 

 Odonate literature is "Selys Cub. — De Selys Longchamps. 

 Neuropteros de la Isla de Cuba en la edicion espanola de la obra 

 de la Sagra ' Historia fisica, politica, y natural de la Isla de Cuba, 

 tomo VII, 1865.' " This is presumably the Spanish edition cited 

 by Hagen in his Synopsis of 1861, p. xv, and in his Bibliotheca 

 Entomologica, II, p. 101 ; in the first citation he gives the date 

 as 1857, in the second as 1856, but adds: "Erschien nach 

 Gerstaecker wohl erst 1857." It will be observed that Gundlach 

 dates it 1865 and in listing Guerin's work in the same Tomo VII 

 of Sagra, in his bibliography for Hymenoptera, p. 9 of this present 

 volume, he likewise quotes it as of 1865. In his Apimtes para la 

 fauna Puerto-Riquena,^ however, Gundlach gives the date of this 

 "Edicion espanola" as 1856. Since the Spanish edition has not 

 been quoted by de Selys himself, as far as I am aware, nor by 

 Hagen, Kirby, jVIuttkowsky, Ris, nor by any other author except 

 Gundlach, I have retained Gundlach's citations of it wherever 

 they occur. All other writers, including de Selys, quote from the 

 French edition.
