the margin especially above the upper median branch; the undulate line is defined against the leaden-violet 
marginal area only by the contrast between the dark postmedian area. Hindwing blackish-grey. Several speci¬ 
mens from Mt. Tolima (Colombia). — lentiginosa form. nov. (14 e) seems to me to belong to it; it has the maculae 
filled up with a ferruginous yellowish colour, the reniform macula below distally with a bluish-white dot. 
From the Quindiu Pass. 
10. Genus: Sjasioiiyctsi Auriv. 
It entirely resembles the preceding genus in the anatomical marks, but the thorax is interspersed with 
scales, and the prothorax and metathorax exhibit loose tufts. As to the genus itself and its palearctic forms 
vid. Vol. Ill, p. 85 and tables 20 and 21. 
L. rainierii Sm. (14 e) is on the forewing bluish-grey, dusted with a blackish brown, in the discal area 
darker with blackish transverse lines, the posterior line dentate with grey maculae encircled with black in a 
blackish ground; the undulate line is formed by small grey lunae proximally with small black sagittae. Hind¬ 
wing of a greyish brown. United States (Mt. Rainier, Wash.). 
L. subfuscula Grt. (14 e) is similar to the preceding, but the maculae are situate in a not darkened 
cell; the forewing is violettish-grey, dusted with a blackish brown, with similar transverse lines, the distal line 
being double by dots on the veins behind it; a faded median shade is present; the undulate line consists of 
a row of intense brown sagittae. Hindwing greyish-brown with light fringes. Montana, Oregon, Colorado. 
L„ sedilis Smith (14 e) resembles subfuscula , but it is easily discernible by the very intense median 
shade covering almost the whole discal area; the ring-macula is larger, white, surrounded with black. Utah 
and Colorado. 
L. conjugata Smith (14 e) has bluish-white forewings mixed with a blackish brown, very similar 
to rainierii , but the discal area is not darker than the other ground of the wing; the black transverse lines 
are strong, the posterior line dentate; the cell between the large grey maculae is darkened by black, the ring- 
macula is oblong, at both its ends pointed, above and below open; the undulate line is only marked by the 
marginal area behind it being darkened and by a dark costal spot before it. Hindwing of a greyish brown. 
Colorado. 
L. ariefis Grt. (14 e) is much lighter than the preceding, white, dusted with purple-brownish, and 
a yellowish basal ray; the black dentate transverse lines are on the averted sides edged with white; maculae 
of medium size, with brownish-grey pupils, with white rings and surrounded by black; the whitish faded undu¬ 
late line, is marked with small yellowish spots, with black dots on them; fringes speckled white and black. The 
white hind wing is dusted with brownish, with a dark median line distally bordered with a lighter colour. Cali¬ 
fornia. 
L. ocliracea Riley (14 f) resembles arietis, but it differs by a brown dusted discal area on which the 
veins, the costal and proximal margins remain white, and by the large coniform macula in a whitish ring and 
encircled with black; the upper maculae are surrounded more with yellowish; also the marginal area behind 
the yellowish-spotted undulate line is dusted with brownish. California. 
L. conifera Dyar differs from the other allied species of this genus by the eyes being only scantily 
covered with hair. Forewing grey with a bronze-yellowish tint; the blackish, broken, faded transverse lines 
are double, the posterior line filled up with a somewhat lighter colour; the coniform macula is a semicircle, 
the light upper maculae are surrounded with black, the reniform macula shaped like a star with five light- 
pupilled points; the undulate line consists of a row of small prominent spots being in front bordered with 
black; marginal area narrow yellowish. Hindwing whitish in the cell, behind it brownish-grey. Expanse of wings: 
31 mm. Peru. 
L. perplexa Sm. (14 f). Forewing purple-grey, dusted with a blackish brown, with single black dentate 
transverse lines and distinct median shades, with maculae surrounded with black and with blackish pupils; 
the whitish undulate line shows proximally black diffuse sagittae. Hindwing brownish-grey. Canada and 
Colorado. 
L. alberta B. A- Ben). (14 a) is very much like perplexa, but distinguished from it by much more 
strongly serrate $ antennae with ciliary tufts. Forewing bluish-grey, very intensely strewn with black, marked 
the same as perplexa, the transverse lines and maculae distinctly bordered with a bluish grey and in bluish- 
grey rings, the reniform macula in the lower half pupilled black; the marginal area is mostly somewhat lighter 
than the other ground of the wing. Expanse of wings: 31 to 37 mm. Canada (Alberta). 
L. marloffi Dyar. Dark bluish-grey, scantily strewn with white; the anterior transverse line is indis¬ 
tinctly blackish with 2 larger bows, the distal line dentate, outside edged with a lighter grey, with white dots 
on the black median branches; the light large maculae are faintly bordered with dark, the ring-macula touches 
with a point the reniform macula distally; undulate line irregularly shaded. Hindwing dark, strewn with 
blackish, with a faint lighter median line and discal spot. Expanse of wings: 37 mm. Idaho, taken in June; 
it was described as an Anytus, but it belongs hereto.
