oblique fasciseform shades, one from the middle of the costa to the dorsal margin, the other 
before the apex, extending through the cilia above the anal angle : several shining steel-blue 
spots from the base to beyond the middle of the wing, followed by two or three streaks of the 
same colour in the apieal third. Hind wings fuscous brown ; the cilia variable, brownish or 
yellowish white. 3 , 2 ? . Expanse of wings 15 millims.

Sericoris inquietana. (Plate LXVIIT. fig. 5.) 
Psedisca inquietana, Walk. Cat. Lep. Het. xxviii. p. 378. 
Misodia? sp., M'-Lacldan, Jouni. Linn. Soc, Zool. xiv. uo. 74, p. 116. 
Palpi whitish grey, projecting scarcely the length of the head beyond it, the middle joint 
thickened, apical joint depressed, exposed : head and antennfe greyish fuscous : thorax brownish 
fuscous in front, greyish behind. Fore wings — with the costa straight; apex rounded ; apical 
margin oblique, not indented — whitish grey, streaked and mottled irregularly with brownish 
scales ; with a brownish mottled basal patch, mixed with fuscous, projecting along the upper 
edge of the cell, indented below it, and a central fascia of the same colour, of which the inner 
edge follows irregularly the line of the basal patch ; this fascia has a small sinuous indentation 
on the projecting portion of its outer edge, above the middle, and is widest on its dorsal half, 
but narro'wed at the costa : the apical portion of the wing is irregularly streaked and mottled 
with a series of brownish spots, mixed with fuscous scales : cilia greyish white. Hind wings 
dull dingy gi'ey. Type $ . Expanse of wings 24 millims. 
Arctic America. Presented by Sir J. Richardson. 
Two specimens of this species, brought by Mr. Hart from the winter quarters in Griunell Land 
of the Discovery^ in the last Polar Expedition, are mentioned by Mr. M'^Lachlan (Journ. Linn. 
Soc, Zool. xiv. no. 74, p. 1 16) as probably identical with specimens in bad condition in the British- 
Museum collection representing Retinia septentr'ionana of Walker's catalogue (pt. xxviii. p. 373). 
He adds that they do not agree with the description of Orthotcenia septentrionana, Curt. 
(App. Ross's 2nd Arctic Voyage, p. 77) . Curtis gives the expanse of the wings of his species 
as 7 lines, and Walker's specimens under that name measure about 8J lines, whereas those 
described by M'Lachlan (expanding \\\ lines) appear to agree with inquietana (Hi lines) 
not only in structure and markings, but also in measurement. 
Walker's Sciaphila primariana, measuring 7 lines, is evidently the same species as his 
supposed septent7'ionnna, Curt., which I venture to think would have agreed with Curtis's 
description had they been in better condition. 
Packard's descriptions of Penthina tessalana (expanse under 8 lines) and P. fulvifrontana 
(expanse about 7 lines), in the Proc. Bost. Soc. Nat. Hist. xi. pp. 55, 56, and Clemens's 
description of Mixodia ? intermistana, Proc. Ent. Soc. Phil. v. p. 140, which must all be closely 
allied species, appear to agree more nearly with septentrionana, Curt., than with inquietana 
Walk.
