372 guxdlach's work ox the odonata of cuba 



I have compared one male from Cuba, Gundlach, 1864, 21, 

 with Gundlach's description [of the male as fixed by "frente y 

 vertice con un brillo de aziil de acero," sex not mentioned]. This 

 male is a little smaller than the dimensions copied by Gundlach 

 from Hagen (1861), viz. : total length 34 vs. 38 mm., alar expanse 

 55 vs. 58, pterostignla 3 vs. 3.5, and the colors of the abdomen are 

 less vivid, but very likely this latter difference is due to the 

 description having been made from freshly-caught examples. 



This male and one from Bath, Jamaica, are the only material 

 from the West Indies now at hand which I referred to Erythro- 

 diplax connata a' in the Biologia Centrali-Americana.-^'' They 

 agree in most respects with the E. connata fraterna of Dr. Ris,^'' 

 but they have no hroivn at the apices of the ivings, a feature on 

 which Dr. Ris lays emphasis (p. 498) in distinguishing this 

 Antillean form.

 connata justiniana (Selys). 



Ldbellula Justiniana Selys Cub. p. 190. 



Gundlach's remarks on this species consist only of a Spanish 

 version of de Selys' description and a note on Hagen's usage of 

 the name justiniana.

 nata justiniana (Selys). 



Ob.servada en varies puntos de las islas de Pinos y en Puerto Rico. 



I have compared one male and one female from Cuba (Poej')? 

 one young male from Bath, Jamaica, and one female from Havana 

 (Baker) with Gundlach's description and they agree. 



This is the Erythrodiplax connata f of the Biologia Centrali- 

 Americana^^ and the E. coniiata justiniana of Dr. Ris.'^'-'
