 PhiLa., 1914, p. 402. [Homestead, Florida.] (Unique male.) 



The present insect shows nearest relationship to N. pahistris, 

 but differs decidedly in the considerably larger size and much 

 more elongate form; vertex which tapers more gradually and evenly 

 to the somewhat more broadly rounded apex; tegmina which are 

 decidedly longer but even proportionately decidedly broader, 

 with stridulating field of male more evenly coriaceous and strid- 

 ulating vein alone prominent and broader; caudal femora with 

 proximal portion less contrastingly swollen and areas adjacent 

 to teeth of ventral margins not darkened. 



The stridulating field of the male tegmen is proportionately 

 small and broad, of the same size and form approximately as in 

 small northern males of N. melanorhinus; the stridulating vein is 

 heavy and of medium length with accompanying veins very weakly 

 defined; veinlets of this field very weak. 



One of the caudal limbs of the specimen here recorded is aborted, 

 no longer than the median limb, with only the median pair of the- 

 distal tibial spurs present. The ventral margins of the caudal 

 femora are armed with small spines, internal 6-7, external 6-8 

 in number. 



Both specimens before us are rather pale tawny olive in general 

 coloration.
