EMARGINEA. By Dr. M. Draudt. 
stripe extends to the postmedian line; undulate line whitish, the fringes with a yellowish tint. Hindwing 
whitish, at the distal margin greyish brown. Expanse of wings: 46 mm. Guatemala. 
resoluta. S. resoluta Dyar (43 a). Forewing brownish-grey with a brass lustre with bronze-brown transverse 
lines, the posterior line distally accompanied by a light stripe rising from the apex; the large maculae being 
surrounded with brown are somewhat lighter than the ground. Hindwing light brown. Mexico. 
ochoa. S. ochoa Barnes (43 b). Forewing ochreous-greenish, in the central area in and below the cell irrorated 
with chestnut-brown, with dark olive green transverse lines, the maculae surrounded with dark olive green, 
besides a median shadow. Hindwing yellowish-olive, strewn with a darker colour except the marginal area. 
Arizona. 
raglena. S. raglena Dyar (43 b) is lustrous brown with a purple tint, with whitish transverse lines, the large 
maculae surrounded with whitish and filled up with a somewhat darker colour; the marginal area remains 
lighter, in it the undulate line which is twice convex and before which there is a dark shadow being divided 
into small round spots, the apex is parted by whitish. Hind wing whitish with brown irroration and a lighter 
median line. Expanse of wings: 37 mm. Mexico (Guerrero). 
aureola. S. aureola Edw. (43 b) resembles ochoa from which it is at once discernible by the absence of the maculae; 
the ground-colour is a purer yellow, irrorated with red-brown, with a purer yellow oblique band from the apex 
to the hind-margin. Hindwing yellowish-white, at the margin brownish. Arizona. 
mavina. S. mavina B. <£• McD. (43 b) approximates the following spumosum, but it is easily discernible from 
it by the ochreous-yellow ground-colour and less distinct marking, particularly the median area is of a brighter 
yellow and therefore contrasts with the marginal area which is strewn more with brown and white; the maculae 
are scarcely noticeably surrounded with white; the apex is parted by white. The hindwing is lighter than the 
forewing, at the margin somewhat darker. Described according to a <$ from Utah. 
spumosum. S. spumosum Grt. (43 b) is reddish-brown, strewn with white, in the postmedian area lighter with 
indistinct whitish transverse lines, the anterior line being straight, the posterior line more distinct. Hindwing 
white, at the margin reddish-brown. Distributed from New York to Arizona. 
manti. S. manti Barnes (43 b) is an insignificant dark brown species strewn with white, in the median 
area and behind it at the costal margin somewhat darker, with slightly darker transverse lines being somewhat 
bordered with whitish on the averted sides, the maculae surrounded with whitish. Hindwing brownish-grey. 
Texas, Mexico. 
cor a zona. S. corazona Schs. (43 b) is much larger than the preceding species, very similarly marked, the ground- 
colour being more olive-brown, with faded greyish-white transverse lines, the maculae also being surrounded 
with that colour; the indistinct undulate line is greyish-white, too. Hindwing ochreous-brown. Mexico. 
psamatho- S. psamathochromum Dyar (43 c). Forewing light brownish-grey with quite indistinct darker brown 
chromum. transverse lines and just as feebly indicated maculae; the undulate line is a lighter shadow which is somewhat 
dentate below the centre. Hindwing whitish, at the margin brownish. Mexico (Tehuacan). 
jalada. S. jalada Schs. (43 c) is grey with a bronze green line with darker indistinct transverse lines, the 
posterior line at its angle connected with a diffuse streak parting the apex; the maculae are also surrounded 
with a somewhat darker colour; marginal area lighter with traces of an undulate subterminal line. The whitish 
hindwing is irrorated with brownish. Mexico. 
crenulosum. S. crenulosum Dyar (43 c) is very well distinguished from all the others by the finely dentate transverse 
lines, the posterior line being double and filled up with whitish, both enclosing the darker median area, also 
the marginal and subbasal areas being darker than the light reddish-brown other ground-colour; the whitish 
reniform macula is centred with a brown lunula. Hind wing whitish, at the margin brownish. Mexico (Tehuacan). 
astigmato- S. astigmatosum Dyar (43 c) is dark grey, finely powdered with white, behind the postmedian line 
sum. lighter with white transverse lines, the somewhat darker maculae finely surrounded with white; the white 
dusty undulate line runs parallel to the margin. Hindwing white, at the margin irrorated with grey. Expanse 
of wings: 22 mm. Arizona. 
navia. S. navia Harv. (43 c) is somewhat similar to crenulosum, much lighter, red-brown, strewn with white, 
in the median and marginal areas somewhat darker, with whitish, very feebly undulate transverse lines; no 
ring-macula, the reniform macula 8-shaped, above and below centred with brown. Hindwing whitish, at the 
margin brownish. Texas. 
128. Genus: £marginea Gn. 
Separated from the preceding genus by a but feeble rounded frontal projection with a horny plate 
below it, and very short erect palpi; the thorax is velvetily clad with scales and hairs, in front tuftless, behind 
with a loose large tuft; the abdomen only exhibits a basal tuft and lateral hair. Middle and hind tibiae on the 
outside very thickly haired, the tarsal joints short and stout. Forewing at the distal margin below the apex
