The large series of the present species, which is the type of the 

 subgenus Neonemobius, before us shows that a very close relationship 

 exists to N. palustris. although typical N. cubensis looks very different 

 from that species, being larger, of less dark and solid coloration, with 

 tegmina almost always much less abbreviate. A careful study of the 

 material at hand shows that there are, however, specimens in the 

 series of cubensis which can scarcely be separated from palustris. 

 These few extreme individuals are as small and of much the same 

 form as palustris, with wings lacking and tegmina quite as abbreviate 

 as in that species. Almost every one of these specimens, however, 

 is not as solid in coloration, and all but two are more pale in general 

 coloration. The majority of specimens of cubensis wanting wmgs 

 have the tegmina considerably less abbreviate than in palustris, a 

 number of these having the tegmina quite as well developed as in 

 those specimens having the longest wings. In summing up the 

 differences between the two species we may add that, in addition to 

 the other differential characters, cubensis usually has the under por- 

 tions of the body quite pale, much paler than is normal in palustris. 



From typical specimens of the western race, A^. cubensis mormonius, 

 typical individuals of the present species may be readily separated 

 by their less robust build and more solid coloration without the 

 characteristic cephalic and tegminal markings of that race. In 

 fact, so different are typical specimens of the two that, were it not for 

 the very large series before us which reveals the vast amount of 

 variability found in these insects, we should certainly have considered 

 them distinct species. 



Small dark macropterous males of N. fasciatus have been mistaken 

 for this species, but the heavier build and less smooth appearance
