So lugens Wlcr. ( = andromedae Bsdv.) (94 c) is distinguished from the similar species by the abdomen 
beneath, on the white ground of which only the first spot is large and black, the others being very small or 
extinct. Forewing blackish-grey, mostly with a slight brownish hue in the C, with almost the same marking 
as in all the allies. Mexico to Honduras. 
S„ geminus R. & J. is so very similar to lugens that it can only be separated by the different genital 
apparatus and by the ventral side invariably bearing 5 large, well developed black spots. The harp is distallv 
rounded, whilst in lugens it is extended hook-like at the upper angle. Likewise found from Mexico to Honduras. 
S. biolleyi Schs. is very near to geminus, but of a more brown total colouring, intermixed with light 
reddish yellow; a pinkish-whitish antemedian spot below the cell is parted by a black line; a round blackish- 
brown spot in the cell is crossed by a black longitudinal streak, and a white dot is at the cross-vein. The ante- 
median white line of the hindwing is thinner, the fringe more intensely speckled black. 1 $ from Costa Rica. 
S. eremilus Hbn. (=sordida Harr.) (94 d) is very similar to lugens and geminus, but structurally 
separated by the spined middle tibiae — being spineless in the two species mentioned — and by the shorter 
first protarsal joint. Brownish, marked like the preceding species; the black longitudinal streaks are distinct 
and thick. The peculiar larva is distinguished by a three-edged projection on the 3rd thoracal segment and a 
velvety black dorsal spot on the two following ones. It lives on Labiatae (Mentha, Salvia, Monarda). Canada 
to Georgia, to the west as far as Missouri. — mccrearyi Clark shows a darker brown thorax and abdomen above, 
and the ground-colour of the forewings is much darker, too; the upper one of the two small white discal spots 
of eremilus is black here or absent altogether. Bands of hindwing blacker. Manitoba. 
S. pseudostigmatica Gehlen (94 d) is the most closely allied to eremilus and just as large, but 
of more slender wing-contours. Fore wing darker than in eremilus , greyish-brown, without any yellowish tint; 
all the linear markings finer; the white anal dentate line is absent; a light spot in the centre of the cell, the white 
stigma scarcely recognizable; fringe brown. Hindwing much less black, the white median band narrower, the 
black marginal band distally dusted with light grey. Abdomen dark grey; palpi with much denser and longer 
hair. Mexico. 
S. eremitoides StJcr. (= lugens Grt.). Exterior very similar to that of separatus and lugens, but lighter, 
more silvery grey, and smaller than these two, with smaller, more triangular black abdominal spots, the collar 
lacks the yellow spots of separatus, the black stripe on the tegulae is narrower, the basal and central costal- 
marginal areas are whiter, the black apical streak is thinner. The basal white band of the hindwing is greyer, 
the black distal margin narrower. Middle tibiae spineless. Southern States of North America. Larva, according 
to Strecker, light green with 7 white oblique lateral stripes and a black horn. It lives on Salvia in two 
generations, in June and October. 
S. separatus Neum. ( = andromedae Bsdv., lugens Sm.) (94 d) is likewise very similar to the preceding spe¬ 
cies, larger, of a purer grey, irregularly marked and easily recognizable by 2 large ochreous spots on the collar; 
the area between 2 and 4 on the forewing as far as the submarginal line is darkened grey. Larva unknown. 
Colorado, New Mexico, Mexico. — melaena R. & J . shows a much darker grey ground-colour, the black marking 
is therefore less contrasting and the insect also blacker beneath. Mexico (Hidalgo and Cuernavaca). 
S. istar R. & J . (= lugens Wlcr., sordida v. A. Clem., leucophaeata Btlr., andromedae Schs.) (94 e) is very 
similar to separatus, still larger, at once discernible by the absence of the two ochreous spots on the collar. Disc 
of forewing more brownish than in separatus, the black longitudinal streak in the distal half of the cell is absent; 
the antemedian line consists in the inner-marginal half only of two though very thick lines, in separatus of 3 finer 
lines. Distal band of hind wing narrower. Mexico. 
S. praelongus R. & J . is still larger with more elongated wings than istar, otherwise very much like it, 
of a purer greyish white, cell with a black apical streak, a white blotch at the double antemedian line. It may 
be only a southern form of istar from Spanish Honduras. 
S. lanceolata Bsdv. ( = ? leucophaeata Clem., aequinoctialis Bsdv.) (94 e) is one of the largest species. 
Light grey, somewhat more brownish in the disc, feebly marked, but with a large black basal spot on the forewing, 
2 distinct discal black longitudinal streaks and a similar apical streak. Hindwing very extensively black in the 
costal area. Middle tibiae without spines. Mexico, maybe also Panama. 
S„ chersis Hbn. (= cinera Harris) (94 f) is very similar, smaller, darker and of a duller grey, transverse 
markings almost obliterated, the black longitudinal streaks finer, the black basal spot on the forewing absent. 
The ground-colour is decidedly loamy in the nomenclatural form, with brown fringe on the fore wing. Canada 
to Georgia, to the west as far as Mississippi. — oreodaphne Edw. (= chersis Stkr.), from California and Oregon, 
is a smaller form, the black discal band of the forewing is narrower anteriorly, the median spots on the under
