I have compared one male from Cuija (Poey), one male from 

 Jamaica (Johnson) and one female from Eleuthera, Bahamas 

 (Univ. of Pa. Exped.) with Gimdlach's description and they agree.

I have compared one male from Presidio, ^'era Cruz, Mexico 

 (Barrett), one female from Cuba (GuntUach, 1866) and one female 

 from Havana (Baker) with Gimdlach's description and they 

 agree, although the latter does not even mention the wings.

 Rieo. 



I have compared one male and one female from Havana (Baker) 

 with Ciundlach's description, which does not mention the sex of 

 his specimens, but was evidently based on non-adults (if males, 

 at least, were used), as evidenced b}- such expressions as "Torax 

 verdoso-pajizo,'.' of which color also the "Abdomen en los tres 

 primeros segmentos . . . [y] los dos ultimos segmentos y 

 sus apendices" are said to be. This applies fairly well to the 

 10th segment and to the appendages, but not to the 9th which is 

 darker, brown, in dried specimens. Otherwise the description 

 agrees. 



This is the form called Erythnxiiplax ochracea ochracea by 

 Dr. Ris.5»
