T. errans Schs. (74 e). <$. Palpi, head, collar, tegulae and abdomen white. Thorax ochraceous. errant. 
Forewing ochraceous buff, interrupted by a wavy light cinnamon drab irregular line from above end of cell to 
inner margin near base; postmedial and subterminal lilacine shades define a very irregular line of ground colour; 
these are inhent from apex, strongly outcurved between veins 6 and 3 and inbent to middle of inner margin; 
veins mostly white, especially from cell to termen, the discocellular sinuous more broadly white; costa white 
irrorated with grey. Hindwings white. Cayuga, Guatemala. 
T. amalita Schs. (74 e). <$. Head, collar and thorax vinaceous cinnamon. Abdomen white, the dorsal amalUa. 
tufts pink. Forewing vinaceous cinnamon crossed by two fine olivaceous brown lines; the inner line slightly 
inbent from costa, the outer line from apex to just beyond middle of inner margin. Hindwings white, the termen 
broadly shaded with roseate. Nova Friburgo, Brazil. 
T. liox Drc. q. Described as being entirely black above and below. Santo Domingo, S.-East Peru. nox. 
11. Genus: Sarsina Wkr. 
(J. Palpi obliquely ascending, thickly scaled. Antennae deeply pectinated. Legs moderately hairy; 
hind tibiae with two pairs of spurs. Forewing broad; costal margin convex; apex rounded; termen slightly 
oblique; veins 2 and 3 apart towards angle; 4 from angle; 5 slightly above angle; 6 from below upper angle; 
7—9 stalked; 10 and 11 free. Hindwing: costa slightly arched, termen rounded; vein 2 further from 3 than 
3 from 4; vein 4 from angle; 5 slightly above angle; 6 and 7 from upper angle. 
Most of the species of Sarsina are so variable and similar that they can only be separated through the 
genitalia. They form apparently good geographical races. 
Type: Sarsina purpurascens Wkr. 
S. purpurascens Wkr. (74 e). <$. The specimen figured is pale pinkish buff, suffused with olivaceous, purpuras- 
more intensely on the antemedial fascia, otherwise forming shades between the lines more pronounced at costa 
before the postmedial line and at apex. Hindwing light buff suffused with warm buff except at base. The 
cJ are also huffish suffused with dull purple or hair brown. The antemedial fascia in all £ is followed by a 
fine double dark line, the outer one more distinct; postmedial line fine excurved at costa then slightly 
inbent to inner margin either straight or slightly sinuous; subterminal line fine sinuous. Frequently the hindwing 
is suffused partly or entirely with drab. $ less variable, the fore wing has the double line forming a narrow fascia. 
Hindwing varies from almost white to drab. — Walker’s type came from Yucatan, so I have applied the 
name to those specimens which occur throughout Central America. — S genitalia with harpes sym¬ 
metrical, ventrally placed (opposed to tegumen rather than to each other), roughly rectangular in shape, 
slightly broader at extreme base and apex than at middle, apex sharply truncate, a single strong, central, 
outwardly curved thorn from apex and another shorter, straight thorn subcostally placed near and slightly 
behind the apex; uncus long, strong, triangular and broad at base, from middle to apex hook-like and scarcely 
tapering; tegumen a low, strongly chitinized, broadly-based arch; socii and gnathos absent; vinculum weakly 
chitinized; anellus a large, weakly chitinized, irregularly shaped and slightly curved plate with a pair of lateral 
arms which (as they also fuse with bases of harpes) may represent the basal elements of an undeveloped 
transtilla; aedoeagus long, stout (but much longer than broad), straight and tapering from intake of penis 
and with a slender, sharply curved blind-sac (part behind intake of penis) forming the basal third; penis with 
cornutus a large patch of closely set, short, fixed spines. (C. Heinrich.) 
S. violascens H.-Sch. (74 f). <$. Forewing very similar to purpurascens', antemedial fascia followed by violascens. 
a narrow shade and a minutely wavy dark line; a well marked discal point; the sinuous subterminal line broken 
by veins. Hindwing cinnamon buff; a subterminal row of small dark spots. Hindwing below: subterminal 
spots better defined; a fine antemedial line from costa across cell, followed by a narrow dark shade to discocellular; 
a postmedial fine dentate line from costa to vein 2; the inner margin of both wings broadly yellow buff, the 
costal portion of hindwing suffused with purplish. Brazil; Paraguay. — $ genitalia as in purpurascens except: 
harpes larger, stouter, broadest about middle and from there tapering to apex; at apex of harpe a single 
short, curved thorn; another stouter, longer, straight thorn from costa near base. (C. Heinrich.) 
S. Violetta sp. nov. (74 f). <$. Forewings paler than S. violascens H.-S., the shadings pale olivaceous violdla. 
or lilacine. Hindwing buff white or white, the subterminal spots very indistinct. Expanse: 32 mm. Molinas, 
Paraguay. — $ genitalia with a pair of strong apical thorns on harpe. Otherwise as in violascens. (C. Heinrich. )
