nate. The anterior tibiae unarmed. The thorax with a slight pro- 

 thoracic crest. Second joint of the palpus triangular, brown on the 

 sides ; the third joint slight and short, and with the upper surface 

 of the second, white and contrasting. 



Ground color of the anterior wings cinereous, overlaid with 

 brown ; the lines are indicated on the costa by conspicuous oblique 

 brown clashes, below they are simple, brown, and less distinct ; half 

 line present ; the interior line below the costal dash, perpendicular, 

 strongly lobed ; the claviform spot absent; the ordinary spots are 

 almost equal, filled with reddish-brown ; in one male specimen the 

 reniform is white and contrasting; the exterior line is dentate, 

 strongly produced around the reniform, below it is obsolete; a series 

 of yellow dots preceded b} r irregular brown blotches mark the 311b- 

 terminal line ; the terminal space more distinctly cinereous. 



Posterior wings brownish fuscous, with brownish-yellow fringes; 

 no traces of the discal dots or median line. 



Beneath reddish-brown, with discal dots and a distinct common 

 median line. 



Eab. New Hampshire. 



We have seen three specimens of this fine species captured by 

 Mr. C. P. Whitney, at Milford. 



The species is very distinct, the pectinate antennas of the male 

 and the unarmed anterior tibire separate it from almost all the other 

 species of the genus. There is considerable sexual difference in 

 other respects than the antennas ; the males are more purely cine- 

 reous, and have the reniform spot white and conspicuous, the yel- 

 low subterminal spots are also obsolete (at least in the two speci- 

 mens we have seen) ; the females are brown, with the cinereous tint 

 almost entirely confined to the costa and terminal space, the ordi- 

 nary spots are brown and concolorous, and the subterminal spots 

 are yellow and distinct. 



This species approaches M. Guenee's Noctua elimata, from 

 Georgia, but it differs in several essential particulars.
