122 THE CANADIAN ENTOMOLOGIST. 



towards base a slighter darker spot, both of which are the terminations of 

 faint, almost obsolete lines of these colours lying above dark median 

 shades. Seven dark purple or black dots on extreme outer margin, one 

 at end of each N'ein, the space between these dots and sub-terminal line, 

 ground colour, not crossed by white or brown lines. Cilia white, dotted 

 with fuscous, and with a narrow, silvery-white metallic line at its base, 

 through which runs a thin line of fuscous. 



Hind wing : Above and beneath pale fuscous with a purplish 

 reflection, in some specimens nearly white towards base ; cilia white. 

 Under side front wing brownish-fuscous. 



Antennfe pectinate in ^ . Expanse 23 to 31 mm. 



Sixteen specimens ; Anglesea, N. J., June and September ; Key West, 

 Fla.; Las Cruces, N. M., (Cockerell 2071); Walter's St., Cal., April, 

 (J. B. Smith); Yellowstone Park, Wyo., July, (H. S. Burrison) ; Fort 

 Collins, Colo., August, (C. F. Baker) ; South Utah, July, (W. Barnes, 

 M. D.). Co-types U. S. Nat. Miis , No. 8218; collections of Prof Fernald, 

 and my collection. 



The Key West specimen is the most strongly marked ; it differs from 

 all of the others in several particulars, notably : The transverse median 

 line is well defined and continued to dorsal margin, but interrupted 

 between each vein ; between the dorsal margin and median streak are a 

 number of white horizontal dashes and the sub-terminal line curves inward 

 to a greater degree, leaving a much wider space between it and termen. 

 This specimen is, therefore, included with a question mark. 



Fernald's figure of T. edonis, Grt., very fairly represents the mark- 

 ings of the front wings of typical specimens, and I should have been 

 inclined to refer my specimens to Grote's species, but Prof. Fernald 

 assures me that they are not tlie same^ and \ take pleasure in bestowing 

 his name on this widely-distributed species. 



I have specimens from Mr. Willing that are marked very much the 

 same as Fernaldeila, but the colours are ashy-gray, with no ochreous 

 shades, these may prove to be a distinct species, but I prefer to regard it 

 at present as a variety. 



Thaumatopsis Fernaldella, var. nortella, van nov. — Palpi pale gray, 

 heavily speckled with dark purplish ; antennje same, pectinate in $ ; head 

 and thorax cinereous. 



Fore wing : Ashy-gray, with median white streak and dark shades 

 same as Fernaldella, but latter much more intense, nearly black. The 

 transverse dark shade at end of cell is absent, and the white median streak
