S. homoea Rothsch. (136 d) is similar to analis, larger, body and wings slightly tinged with claret- 
colour; forewing longer, the interior angle more rounded, the anterior transverse line more oblique, at the 
costal margin near the cell-apex. Hindwing with a less round costal margin and distal margin. C'lasper-wool 
like the abdomen, not ochreous. South-Eastern Peru. 
S. pelias Rothsch. (135 e). Thorax and base of abdomen ochreous, abdomen posteriorly tinged rosy-reddish. 
Wings loamy ochreous, forewing with straight blackish oblique lines, basal and marginal areas pinkish-brown, 
a round white cellular spot in the lower cell-angle; wings longer than in boisduvalii, speckled with blackish- 
brown, bordered with dark at the inner margin. Hindwing oval, distally rounded, yellowish ochreous, loamy 
brownish at the margin with an indistinct blackish median line not reaching to the inner margin. Length of 
forewing: 52 mm. Bolivia; Chanchamayo. 
S. bellardi Schs. salmon-coloured reddish ochreous on the anterior body, base and end of abdomen, 
the rest of the abdomen pink, legs more lilac pink. Forewing pinkish-brown at the base and marginal area, deep 
chromatic yellow in the median area with some rust-brown striae; transverse lines olive brown, anterior line 
excurved, and angled in the cell almost to the base of the inner margin, the exterior line from the apex to the 
centre of the inner margin, a brownish-pink spot at the cell-end. Hindwing reddish ochreous, somewhat red- 
brown at the inner margin, with a feeble brownish-red distal line. Costal margin of hindwing strongly convex 
basad. Expanse of wings: 43 mm. Valera, Venezuela. 
S. andrea Dogn. is yellow above, rather regularly speckled with black, with a thick discal dot and a 
black line extending from shortly before the apex to the 2nd third of the inner margin and very slightly curved 
inwards. Hinclwing lighter yellow, not striated, with bright red hair in the two interior thirds, and a shadowy 
spot behind the cell on 5 and 6. Expanse of wings: 62 mm. Described after 1 <$ from Venezuela (Caracas). 
S. mexicana Bsdv. (= xanthochroia Dyar) (136 c). Deep yellow, basal and marginal areas rarely 
dusted with violet, oblique lines violettish-brown, a double white spot in a violet ring at the cell-end in the 
whilst the $ shows a violettish-brown round blurred spot. Hindwing with dark red hair in the inner-marginal 
half. Mexico. 
S. boisduvalii Doum. has somewhat broader, lighter yellow wings, the oblique lines are nearer together, 
the hindwing is less and lighter red at the inner margin. Brazil; scarcely to be separated specifically from mexicana. 
S. smithi Drc. differs from the preceding species in the absence of oblique lines and of the cellular spot, 
light yellow, densely speckled brown, especially at the base. The yellow hindwing shows dark red hair at the 
base of the inner margin. From Colombia. 
S. lineata Drc. is likewise light yellow, but much smaller, the forewing basally greyish-brown, a white 
dot at the cell-end, behind it a greyish-brown line from the apex to the inner margin near the base. Hindwing 
monotonously light chrome-coloured. Paraguay. 
S. quadrilineata G. <£• R. Forewing reddish ochreous, base and marginal area tinged lilac, with the 
usual reel-brown oblique lines and 2 large white spots at the cell-end. Hindwing extensively red. Missouri, 
Mexico, Costa Rica to Colombia. Specimens with only one white discal spot are called: unimacula Dogn. 
(136 d), whilst those in which even this spot is absent and replaced by a shadow, are : — occlusa Dogn. Forewing 
beneath with a large black, white-centred spot at the cell-end. 
S. bisecfa Lint. (136 e) has a straighten costal margin, a more oblique distal margin and shorter and 
rounder hindwings than bicolor. Body ochreous, tegulae more pale lilac than the base and marginal area of 
the forewing, the median area bright ochreous and finely striated dark; without a discal spot or with a feeble 
oval ring; postmedian line feebly curved from near the apex to the centre of the inner margin. Hindwing 
ochreous, pinkish carmine in the disc as far as the inner margin. The $ is monotonously light reddish-brown, 
striated darker. nebulosa Neum. is hardly worth being denominated and has a more distinct posterior 
transverse line and blackish-brown discal spot, more yellow hindwings. Larva like that of bicolor, but without 
the silvery horns. Texas. 
S. hoegei Drc. (137 a) is a marvellously variable species; among almost 50 specimens before me there 
is hardly one like the other. Orange, more or less finely speckled red-brown, or all over suffused with red-brown, 
with or without lilac dusting at the basal and marginal areas, transverse lines as usual, the posterior one from 
the apex or before it, at the cell-end one or two white spots which, if they grow larger, form two triangles with 
their apices upon each other like a sand-glass. $ without white spots. Hindwing more or less extensively 
carmine. Specimens with a purely yellow median area and a purple basal area and marginal area are called: - 
montana Pack. ( = phaedima Dyar) (137 a), the hindwing is carmine in the disc, yellow at the margin. - 
kuschei Dyar is the northernmore form, from Sinaloa, a smaller form with a rounder apex, an entirely brownish- 
grey forewing and red hindwing without a yellow margin. The same form, but with yellow forewings, is called: 
- - sinaloana Schs. Distributed in Mexico, also in Arizona. 
S. dollii Pack. I do not know. Larger than hoegei, body and wings reddish-brown, as in Anisota stigma, 
with a lilac tint, not striated; anterior transverse line very indistinct, posterior line regularly curved, to the 
apex; discal spot small, white. Beneath without the discal spot. Mexico.
