lines ami spots iire arranged as in chcnopodii Albin, Init the nuiikinfrs 

 are more broken, and the sipiamation is rouj^li and uneven. The ground 

 color is wliite, almost totally obscured, except in the ordinary spots 

 and on the subterminal space by black or gray shades. The nervules 

 and u portion of the basal space are tinged with glaucous. Half line 

 present. The interior line irregular, simple, obsolete below the clavi- 

 form spot; the latter round, large, whitish, ontlined in black. Above 

 is situated the white, oblique orbicidar spot, containing a central gray 

 shade. The submedian nervure is plainly blackisli. Median shade 

 blackish, suffused and irregular, lost in the dark median space. Kqw'x- 

 form spot white, containing a central gray shade, well sized, unsym- 

 metrical, its detining line broken. The exterior line is black, simple, 

 continuous, dentate, much drawn in below the reniform spot, and form- 

 ing a particularly deep lobe above the submedian nervure. Subter- 

 minal space more or less distinctly whitish below the costa, this color 

 culminating in a very conspicuous white spot, tilling the nieilian lobe 

 of the exterior line. The terminal line is whitish, distinct, but some- 

 what broken, forming two short but evident teeth on the second and 

 thii'd median nervules. The line cuts and divides into two j)ortions 

 the black shades which extend over the terminal and latter part of the 

 subterminal spaces. The usual subapical white dots, and a similar 

 series at the base of the fringe. Posterior wings dark fuscous, becom- 

 ing lighter and partially translucent at the base ; a faint discal dot. 

 The fringes are whitish. Ueneath, very uniform in coloration ; the an- 

 terior wings dark gray ; whitish scales line the costa; the i)OSterior 

 wings are whitish, with a distinct discal dot; a common line extends 

 over both wings.

" Kindly lent me for ideutitication by my friend. Prof. F. X. Belanger, 

 of the Universite Laval. 



"The dark, almost black coloration of the anterior wings contrasting 

 with the four white si)ots in their central portion is characteristic of 

 the species. Of these spots, two, the orbicular and claviform, are com- 

 paratively small and well defined; the remaining two, the reniform and 

 the spot in the lobe of the exterior line, are large and irregular." 



The species of Mr. (rrote's lists not referred to in this pajier do not 

 belong to Mamcstra, but are better referred elsewhere.
