Introduction: The Publication, Distribution and Gen- 

 eral Characteristics of Gundlach's Work on the 

 Odonata of Cuba 



On April 26, 1913, the library of the American Entomological 

 Society acquired a copy of Tomo II of the Contribucion a la 

 Enlomologia Cubana by Juan Gundlach. On examining this 

 volume shortly after, I became aware for the first time of the 

 existence of a fairly extensive work on the Odonata of Cuba 

 which, to the best of my knowledge, has never been quoted by 

 any writer on this group of insects except by Gundlach himself. 

 In his Apuntes para la Fauna Puerto-Riquena, Odava Parte (Anales 

 Soc. Espaii. Hist. Nat., Serie II, Tomo 2, pp. 259-344, 31 

 Enero, 1894), he states: "En el mismo aiio 1888 empezo la publi- 

 cacion mia sobre los Neuropteros de la Isla de Cuba en el tomo II 

 de mi Contribucion a la Fauna cubana, Enlomologia (1)." The
