66 ACIDALIA. By L. B. Peotjt. 



strongly approaching A. ternata perfuTuata. Packard, who has by an error (corrected in his text) figured the 

 Labrador form as spuraria (nee spuriaria Chr.), commits a second error in regarding it as a variety of the 

 schoyeni. North American inductata Guen. — schoyeni Sp.-Sckneid., which also is unknown to me in nature, is said to 

 be a little smaller than typical frigidaria, but to show no important differences. It inhabits Arctic Norway 

 and Arctic Finland. 



cajanderi. A. cajanderi Herz, only known to me from the description, seems to be nearly related to the prece- 



ding, possibly even another form of it. It is described as varying from dark grey to reddish brown, thickly 

 dusted with black scales, glossy; discal spot present or absent; forewing with 2 — 4, hindwing with 2 — 3 

 indistinct dark transverse lines and with a distinct black distal marginal line; the middle line the strongest 

 on both wings; under surface a little lighter. Somewhat broader than frigidaria, distal margin of forewing 

 more convex. Antenna in (^ serrate, shortly ciliated. A series of 11 specimens was taken at the junction of 

 the Vilui with the Lsna River, Siberia, 22. to 24. July, and a worn example was also met with at Verkhoiansk. 

 I possess an undetermined (J from Barracouta Bay, 28. July, which may possibly belong here, altough the 

 fauna of the Lena District is more nearly of a circumpolar character. The specimen in question is likely to 

 be of the species which Staudinger identifies as f^imata (= ternata) from Amurland; but if so, he must have 

 neglected to examine the structure, for the hindleg is without spurs and the hindwing has the second sub- 

 costal vein shortly stalked. Otherwise it is remarkably like some Arctic forms of ternata. The figure of cajan- 

 deri does not show whether the second subcostal vein of the hindwing arises from the apex of the cell or is 

 very shortly stalked. 



marcidaria. A. marcidaria Leech (3 1). Whitish suffused with yellowish, especially m basal part of forewing and on 



the veins. Lines darker yellowish, rather diffuse and ill-defined. Inner line of forewing usually lost in the basal 

 suffusion; median line rather thick and oblique, closely following the cell-spot on the forewing, passing proximally 

 to it (sometimes touching it) on the hindwing; po?tmedian line somewhat dentate, usually a little incurved 

 between the radials and in submedian area; two thick outer lines enclosing the whitish subtermiI^al, commonly 

 meeting on the veins so as to break up the subterminal into spots; cell-spot minute but black. Hindwing 

 slightly angled at extremity of third radial. Underside less yellowish, forewing slightly suffused with grey, 

 hindwing more white, both wings with the cell-spot and the lines distally to it well expressed; distal margin 

 with brown line and dots. Face concolorous with wmgs. Antennal ciliation in o long, hindtarsus considerably 



intaminata. shorter than tibia. Western China: Wa-Shan, Chia-ting-fu and Ta-chien-lu, June and July. — ab. intami- 

 nata ab. nov. has the lines finer, of a rather brighter yellow, the basal suffusion of the forewing confined to a 

 streak along the anterior edge of the cell. Wa-Shan in June, one ^ (type) from the Leech collection, now at 

 the British Museum. 



lutearia. A. lutearia Leech (31) resembles marcidaria in general aspect, but is more strongly and uniformly yel- 



lowish or ochreous in tone, lacks the black discal dots and in particular has the margin of the hindwing scarcely 

 appreciably bent. The median line is still thicker, and the shading on either side of the subterminal occupies 

 nearly the whole of the distal area, only separated from the postmedian by a narrow pale line. Similarly 

 the under surface of the forewing is more strongly suffused with yellowish brown. Face blackish. (J antennal 

 ciliation shorter, hindtibia strongly thickened, tarsus much abbreviated. Ichang and Chang Yang, June and July. 



floslaciala. A. floslactata Haw. (= remutata Schiff. nee L. = ? fulvostriata Goeze = ? brunneata Goeze = ? fulvi- 



cans Geoff. = 1 strigata Geoff. = ? cariata Schr. = lactata Haw. = spataceata Wrnbg. nee Scop.) (4i). Yellow- 

 ish white, sometimes slightly more tinged with greyish, with scattered black atoms. The lines light yellowish 

 brown, sometimes a little greyer; first line of forewing weak, sometimes absent, usually placed rather far 

 from the base, thus near the middle line, with which it is sometimes more or less connected by dark shading 

 in the middle of the wing; middle line sinuous; postmedian usually more sharply expressed, dentate outwards 

 and with moderately strong curve mwards between the radials and usually in submedian area; subterminal 

 dark lines never strong, sometimes wanting or the proximal alone present; forewing very rarely with a small 

 and weak dark cell-dot, hindwing usually, but not invariably, with a small black one; distal margin often 

 without black dots, sometimes with some very minute ones in anterior half, very occasionally continued further 

 posteriorly. Under surface of forewing, especially in the cJ, slightly clouded with smoky brownish from base 

 to median line and from costal margin to somewhat behind the cell ; median and postmedian lines rather more 

 smoky in colour; cell-dot often present. Hindwing beneath whitish, usually with distinct cell-dot and post- 

 median line, often also with the proximal of the subterminal lines present, though less prominent. Antennal 

 ciliation m the ^ little longer than the diameter of the shaft, hindtibia thickened but not shortened, tarsus 

 scarcely one-fourth of its length. Moderately variable, chiefly in the distinctness of the lines and the strength 

 of the teeth and curves in the postmedian line, but also to some extent in the ground-colour, which is at times
