Other brachypterous specimens before us are even darker than the 

 normal coloration, being colored very similarly to A^. palustris, but 

 in almost all cases having much longer tegmina, and in the one or two 

 cases where this is not true they are larger than the largest specimens 

 of that species. 



Distribution. — The present species is known from Staten Island, 

 N. Y., south along the Atlantic coast to the extreme southern portion 

 of the mainland of Florida, and also from Cuba, Vera Cruz in Mexico, 

 Nicaragua and Costa Rica to Brazil. Its western distribution in the 

 United States appears to be limited bj^ the fall-line. The records 

 given Ijy Scudder and Blatchley for Illinois and Indiana pertain to 

 other species. 



Biological Notes. — Though seldom numerous, the present insect 

 appears to be always much more plentiful near the sea than elsewhere ; 

 the writer has found it in large numbers but once, in the high grass 

 of the everglades. Of all the North American species of Nemohius 

 it develops in the macropterous form proportionately the longest 

 tegmina and wings. The majority of macropterous specimens 

 taken have been captured flying to lights at night ; about such places 

 we have never found this insect anything but very scarce. Con- 

 sidering the usual extreme development of the tegmina and wings 

 in the present species, it is surprising to find some brachypterous 

 specimens with tegmina quite as much aborted as in A'', palustris. 



Synonymy. — In 1877, Scudder described Nemohius volaticus, which 

 species he himself placed in the synonymy under cubensis in 1896. 

 We here select a male of that series from Georgia in the Scudder 

 Collection as single type.^^ 



In Scudder's 1896 paper on the North American species of the 

 genus, he unfortunately created confusion by misidentifying much 

 material, one instance of which was the crediting of specimens of the 

 present species from Lake Worth, Fla., to A^. carolinus and another 

 in taking a small dark brachypterous female of cubensis as the basis 

 of the description of that sex of his new and doubly invalid A^. aterri- 

 mus. 



In 1905, Rehn and Hebard, at a loss to fathom the literature, 

 credited a pair of dark cubensis, having long tegmina but no wings, 

 from Tampa, Fla., to aterrimus. 



Specimens Examined.^* — 67: 14 males, 52 females, and 1 nymph. 



*3 The female before us is a macropterous specimen of N. carolinus. 



^* The following abbreviations are used to differentiate the specimens here 

 recorded: b., brachypterous; m., macropterous; I. teg. only, long tegmina only; 

 med., medium; v., very.
