C. lucina Drc. (20 b) has light greyish-brown forewings, in some places dusted with purple brown, 
the most intensely in the area between the antemedian line and median line; the anterior transverse lines are 
double, the posterior line very indistinct; coniform macula very short and broad, surrounded with black; the 
ring-macula is above pointed and below widened, the reniform macula very indistinct, between both there 
runs an undulate median line. Undulate line light-, proximally bordered by small dark spots, the marginal area 
behind it is darker. Hindwing dark greyish-brown. Mexico. 
C. rdveopicta Btlr. (= florinda Btlr.) (14 a). Purple brown, dusted with black and grey, with double 
anterior and single sharply dentate posterior transverse lines, the latter line dist-ally bordered with grey, and 
black streaks run to it from the reniform macula which is open above and below; traces of the median line; 
the undulate line is marked by a row of small black, white-dotted streaks. Hindwing white with brownish veins 
and margin, in the $ entirely darkened. Chile. 
C. terranea Btlr. (14 a). Reddish-brown, strewn with black, marked the same as the preceding, but 
the white dots of the undulate line are absent, but instead there are ochreous-yellow and black small sagittae. 
Hindwing yellowish-white with brownish veins and margin. Chile. 
C. yakima Sm. (13 i). Forewing greyish-white, thickly strewn with greyish brown, with a black basal 
ray, with quite indistinct, only at the costal margin better marked double transverse lines; reniform macula 
below filled up with dark; the indistinct whitish undulate line exhibits proximally small dark sagittae, behind 
it the marginal area is darkened. Hindwing of a pure white with a dark margin. Washington, Utah. 
6. Genus: ^cotogriiMina Sm. 
It has quite the same anatomical marks as the preceding genus, but the frons has no conical projection, 
but a rounded convexity with a slight vertical ridge and a horny plate below it. All the rest quite the same. 
Comp, also Vol. Ill, p. 68, and Vol. XI, p. 69. 
S. orida Sm. (13 i). Forewing greyish-white, thickly strewn with brownish black, with quite indistinct 
transverse lines, only at the costal margin better marked, the posterior line pointedly dentate on the veins; 
maculae with dark pupils and in white rings; undulate line white with a distinct W, in the centre behind it a 
dark spot. Hindwing white with a blackish-brown marginal band. United States (Utah). 
S. nevada B. <£■ McD. (14 a) is in the colouring and marking very similar to orida and also to 
Cr. yakima (31 i), but the hindwing is in the of a pure white with a fine, smoky grey marginal line and with 
a post-median line marked by dots on the veins, in t-lie $ smoky brown, towards the base somewhat lighter. 
Nevada. 
S. trifolii Bolt. (— inquieta Wkr., glaucovaria Wkr., major Spr.). This extremely common specie 
has been dealt with at- large in the palearct-ic part (Vol. Ill, p. 68, t-. 15 g) and also occurs in America from Canads 
down to Arizona and Mexico; it- is before me from Mexico City, taken in July; then it also occurs again in Chile. 
—- f. albifusa Wkr. has more red-brown forewings with whitish dusting in the costal and subterminal areas, 
the undulate line shows stronger black sagittae in front of it. The type of this form originates from Nova Scotia. 
As to the Indian forms of this species vid. Vol. XI, p. 69, 70. 
S. mutata Dod. is very similar to trifolii (Vol. Ill, t. 15 g), of a more slender structure, with more 
extended wings, lighter with more contrasting markings and a more pointed W in the undulate line. The hind¬ 
wing is darker. From Canada, Colorado, Utah to California, Texas and Arizona *). 
S. oregonica Wkr. (14 a), which Hampson considers to be a form of trifolii, is a distinct species. It 
looks very much like trifolii and is marked the same, but the ground-colour of the forewing is greyer, more 
thickly strewn with light brown. The type is from Oregon. — The form morana Sm. has a more yellowish greyish- 
brown ground-colour, of a very uniform tint, without contrasting markings; the undulate line is broken, without 
distinct small sagittae in front of it, mostly only with a feeble shade, which is very conspicuous on the under 
surface as a dark band. Colorado, Wyoming, Yellowstone Park, Washington, British Columbia. 
S. harnhard! B. <£• Benj. is very similar to densa Smith (p. 105) having now been placed to this genus. 
Forewing dull red-brown intermixed with black scales, with effaced markings, instead of the reniform macula 
only a darkened patch; the undulate line is only shown by the somewhat lighter marginal area. Hindwing 
uniformly dark like the forewing with somewhat darker veins and a lighter basal area. Expanse of wings: 33 mm. 
Utah. 
S. addenda B. <£• Benj. in its exterior resembles submarina (13 k). Forewing narrower, dull olive- 
grey, with double anterior transverse lines and a single, on the veins pointedly dentate posterior transverse 
line; the ring-macula and coniform macula are absent, the reniform macula only feebly traceable in a darkening 
*) As we have been lately informed by Mr. Benjamin, it is to be placed to the genus Cardepia, whereas jrancisea 
(p. 105), megaera (p. 105) and densa (p. 105) are to be transferred from Folia to this genus, just like obesula and ortruda 
(P- 98). ' ... .; •
