gray. Anterior wings gray, the transverse lines nearly obsolete ; 

 a distinct, long, black, basal dash ; ordinary spots as well as the 

 costal region slightly lighter than the ground, the former having 

 partially effaced black annuli, the space between them dark ; 

 transverse lines, where present, geminate ; a series of snbterminal 

 cuneiform spots replacing the usual line, a lobate line at the base 

 of the concolorous fringe. 



Posterior wings light at the base, darker towards the margin, 

 fringe light. Under surface unmarked. 



Hab. Orono, Maine. (Prof. C. H. Fernald.)

 Abdomen rounded, untufted, the lateral tufts brownish. 



Anterior wings uniform, faded yellow-gray, with the ordinary

 Mamestra quadrannulata, nov. sp. 



Expanse 30 mm. Length of body 15 mm. 



Eyes hairy. Front, palpi, collar, and prothorax black, shading 

 to gray towards the abdomen. Abdomen gray. Basal and me- 

 dian spaces of the anterior wings crossed by two broad longi- 

 tudinal yellow-brown bands, one costal, the other extending 

 along the inner margin ; these bands inclose a central triangular 

 purple-gray or purple-black space, in the upper part of which the 

 two ordinary spots are seen, very small, of the same size, con- 

 colorous, surrounded by incomplete intense white annuli ; a long 

 black basal dash reaching to the small black encircled claviform 

 spot ; median transverse lines entirely obsolete; subterminal line 

 consisting of a series of white dots, preceded by black cuneiform
