60 PROCEEDINGS OP THE ACADEMY OF 



related to M. incincta, Morr. Eyes hairy. Antennae simple in 

 both sexes. Thorax with a slight prothoracic tuft, concolorous 

 with the anterior wings. Abdomen short, untufted. 



Ground color of the anterior wings light yellowish-gray, almost 

 entirely overspread with blackish, the lighter color appearing 

 principally between the geminate median lines, and in scattered 

 patches on the basal, median, and subterminal spaces ; a distinct 

 black basal longitudinal dash ; interior line straight, oblique, den- 

 ticulate, its outer component line black and best expressed ; 

 median shade obsolete ; ordinary spots unusually small, black, 

 with incomplete ochreous annuli, the reniibrm followed by a light 

 spot ; exterior line black, geminate, its inner component line the 

 most distinct; it is incepted on the costa directly above the reni- 

 ibrm spot, boldly produced around it and drawn in below it, nar- 

 rowing the median space ; subterminal line obsolete ; a distinct 

 broad light subapical streak ; terminal space black, a yellowish 

 line at the base of the concolorous fringe. 



Posterior wings whitish, with a discal dot, narrow connected 

 median line and a broad suffuse blackish terminal band ; an inter- 

 rupted black line at the base of the whitish fringe. 



Beneath, yellowish white, sprinkled with numerous black atoms ; 



discal dots distinct, as well as a very prominent black median 



line. 



Hab. Glen Valley, near Mt. Washington, N. H., and Plymouth, 



Mass. 



The former specimen was received from Mr. S. H. Scudder, the 

 latter from Mr. Edward Burgess, and was taken July 23, 1867.

 our other Mamestrae, and we think will not be difficult to recog- 

 nize.

Eyes naked, with short lashes. Antennae of the female simple. 

 Abdomen untufted, with a short projecting ovipositor. Tibiae not 

 spinose, the anterior pair provided with a slender claw at the ex- 

 tremity. 



Anterior wings clear bluish-gray, the markings black ; interior
