S. suffecta sp.n. (16 g). Rather strongly recalls defixaria (18 b) in size, coloration and markings. 
Hindleg of the quite different, the tarsus nearly 2 :3 as long as the tibia. Further distinguishable by the some¬ 
what more curved termen of the forewing and especially the more angled hindwing, also by the black dots on 
the postmedian line; the terminal dots are on the underside connected by a dark line, at least on the forewing. 
Rio Pacaya, Rio Ucayali, June—September 1912, 2 and 1 $ in the British Museum. A somewhat larger 
(26 mm) and longer-winged $ (abdomen wanting), from Prov. del Sara, Bolivia (J. Steinbach), either represents 
a race or a very close ally, transitional towards dismutata. 
S. dismutata Guen. (= catenularia Walk.) (16 h). I have not seen Guenee’s type, a <$ from “Brazil”, 
but the description agrees so perfectly with catenularia that I do not doubt the synonymy. Fascicles of $ antenna 
well developed, hindtarsus about 2 3 tibia. Differs from napariata in the latter character, its more angled hind¬ 
wing and weaker markings (especially beneath). Brazil. Generally much larger than suffecta, forewing with 
the termen and especially the median line more oblique, hindwing with rather sharper angle. 
S. nostima sp. n. (16 h). Similar to the most brown-tinged examples of dismutata. hindwing with the 
angle scarcely as strong, though a little stronger than in suffecta ; hindtarsus almost as short as in napariata. 
Cell-dots sharp, that of the hindwing slightly enlarged; markings above and beneath otherwise closely as in 
typical napariata or with the antemedian and median lines of the forewing slightly more oblique still. Colombia. 
El Congo, Cauca Valley, type <$ in my collection, paratype in that of the British Museum. The shape, colour 
and markings differentiate it sharply from n. aerates (16 li). 
S. napariata Guen. (16 h). Variable in colour and in the strength of the markings and even in the exact 
develojnnent of the angle at the 3rd radial of the hindwing, though this is never acute; generally somewhat 
suggestive of the least white forms of nigropunctata Hufn. (Vol. 4, pi. 4 k). Hindtibia of the <$ strongly dilated, 
thickened distally, tarsus very short. S. E. Brazil and Paraguay, the type probably from the Rio district. - 
aerates subsp. nov. (16 h) presents a different aspect, perhaps sufficient to indicate a separate species. Paler 
than the type and even when compared with the whitest Brazilian forms distinguishable by having the post¬ 
median line somewhat farther from the termen; median shade rather weak, never much thickened, on the fore¬ 
wing about parallel with postmedian (in n. napariata generally a little more oblique), on the hindwing generally, 
arising well proximal to the end of that of the forewing, not (as in most n. napariata) a continuation of the 
latter; subterminals rather weak; underside weakly marked, the hindwing without the subterminal line which 
is frequently conspicuous in the type form. Colombia to Bolivia, the type J in the Tring Museum, from La Union, 
Rio Huacamayo, Carabaya. 
S. paetula Prout (16 h). Coloration and aspect of napariata or slightly warmer in tone. Antenna and 
hindtarsus of the more as in dismutata. Forewing with termen oblique, as long as hindmargin; cell-dot variable 
in strength, placed on the posterior extremity of the 3rd discocellular; post- 
median at its costal extremity somewhat thickened but indefinite, more displaced basewards than in napariata. 
Underside nearly as in that species, the forewing rather more suffused. Sierra del Libane, Magdalena, Colombia, 
at 6000 feet. 
S. alargata Dogn. Somewhat narrower winged than dehortata, apex of forewing more acuminate; much 
greyer and duskier, hindwing less angled, median line heavy. Loja, only $9 known. The only specimen before 
me is a poor $ from Zamora. 
S. falcataria Warr. (16 h), founded on a single $ from Carobas, Peru, 2500 feet, is also in bad condition 
and may well be a form of alargata. Face apparently less black; wings slightly less yellowish tinged, the median 
shade perhaps thicker, this and the postmedian line on the forewing sinuate inward between the radials, whereas 
in alargata all the lines of the forewing are pretty straight. 
S. omissa Warr. (16 i)). Greyer than dismutata, more as in the European nigropunctata Hufn. (Vol. 4, 
pi. 4 k). median shade as thick as in that; apex of forewing rather more acute than in dismutata, hindwing less 
quadrate, less sharply angled at the 3nd radial, postmedian of forewing less bent near the costa, forewing 
beneath more infuscated, etc. Founded on a $ in the United States Museum from “Bolivia”, probably (like 
the 3 here figured) collected by Garlepp. Rio Songo to Rio Suapi; occurs also at Oconeque, S. E. Peru. The 
$ hindtarsus is nearly as in dismutata. the tibia thicker. The $ has the median shade heavier. 
S. quinquelinearia Pack. (= quinquelineata Pack.) (16 i). A common North American species from the 
Rocky Mountains westward, first described from California. Expanse about the same as in limboundata (16 g), 
but apart from several other obvious differences it has a scarcely shortened $ hindtarsus and usually much 
suffused forewing beneath, at least- in the G<S- The variation is chiefly in the strength of the lines, some of which 
are frequently very weak; blotched aberrations are unknown. — ab. impunetata Warr., described as a species, 
or at least “the Colorado form”, only differs in the loss of the cell-dots, which, however, are generally very
