 a dark fuscous transverse spot ; beneath, each segment has a 

 large black macula on each side, which occupies the greater 

 part of the segment. 



Hah. Para. 



This species resembles the type of the genus, N. scevissimus, 

 also found at Para ; but it has a broader head, its prothorax is 

 proportionally shorter, as is also the metathorax ; it differs 

 also in having ferruginous claws and in the coloration of the 

 wings, and in having the clypeus maculated.
