A TABLE OF THE GENERA OF NOCTUIDiE OF 

 NORTHEASTERN NORTH AMERICA. 



By Wm. T. M. Forbes, 

 Worcester, Mass. 



As the last general view of our Noctuid genera, published by 

 J. B. Smith in the Bulletin of the Brooklyn Entomological Society, 

 is now obsolete, a new synopsis of them, even for a limited fauna, will 

 prove useful. 



The Noctuidse may be defined as moths with simple or pectinate 

 antennae, with regularly tapering shaft, with labial palpi developed 

 and maxillary palpi, in our species, rudimentary. Ocelli always 

 present, and rarely covered with scales. Fore wing with one devel- 

 oped anal vein, with cubitus apparently four-branched, R3 and R^ 

 never arising separately from the cell. Hind wing with two devel- 

 oped anals, with a strong frenulum, simple in the male, usually of 

 three bristles in the female. Sc and R arising separately at the base, 

 the base of Sc curved and moderately thickened, not sending a brace 

 across to the base of the frenulum; the two veins more or less com- 

 pletely fused for a short distance, the fusion commencing less than 

 a fifth way out on the cell and very rarely extending beyond the 

 middle. 



The characters used in dividing the genera are drawn from all 

 parts, but the venation is of less value than in most families. The
