S. festiva Schs. (74 f). Body and wings cinnamon buff. Forewing: the lines very fine slightly 
darker like the apical third; a black discal point. Hindwing with faint sub terminal points. Underneath the 
costal half of wings purplish chestnut, the inner half buff yellow; two pale medial streaks on costa, also post- 
medial line on costa; hindwing with faint postmedial and subterminal lines on dark portion. The specimen 
described in A. M. N. H. 1912 p. 40 belongs to S. purpurascens Wkr. $. Abdomen ochraceous buff. Forewing 
light ochraceous buff suffused with lilacine, purplish at base of costa and near lines; the lines fine, dark olive 
brown; antemedial line almost vertical; postmedial line straight, inbent; subterminal line wavy. Hindwing 
light ochraceous buff; a series of darker spots from apex to inner margin above anal angle. Underneath: 
forewing buff yellow suffused with purplish red; costa for two thirds from base pompeian red, crossed by two 
pale medial lines; the three lines dark, straight, the subterminal the broadest. Hindwing suffused with purplish 
red except on inner margin; darker medial, postmedial and subterminal lines; faint terminal spots. Expanse: 
d 35 mm, $ 56 mm. 'Costa Rica; Venezuela. — $ genitalia with harpes asymmetrical; left harpe with three 
outer costal thorns (one at extreme apex and two iust behind in a row) and with a similar thorn on costa near 
base, right harpe with but two outer costal thorns, none of the thorns on either harpe appreciably curved; 
harpes shaped as in violetta and violascens ; blind-sac of aedoeagus quite slender and but very slightly curved; 
cornuti very weak, nearly a weak-though extensive-scobination of the penis. (C. Heinrich.) 
S. electa Schs. (74 f). $. Body vinaceous fawn. Forewing deep purplish vinaceous, the base, outer 
edge of antemedial fascia, a broad medial shade, inner edge of postmedial and subterminal lines and the termen 
narrowly pale vinaceous lilac; lines straight except the sinuous subterminal line. Hindwing vinaceous fawn, 
darkest on termen. Forewing below vinasceous buff suffused with purple; costa partly, a broad shade before 
postmedial, and termen broadly vinaceous brown, the apex lilacine. Hindwing below with a broad vinaceous 
brown fascia inbent from beyond middle of costa, becoming narrow and obsolete towards inner margin, followed 
by a fine dentate line; basal half of costa and termen vinaceous brown. The specimen described in the Annals 
as the (J of this species is in reality a $ of S. purpurascens Wkr. Costa Rica. 
S. dirphioides Wkr. (= quadristrigata Fldr.) (74 f). This species is so similar to S. purpurascens Wkr. 
that no description would separate it. Walker described a $ from an unknown locality. As it is impossible 
to examine the genitalia of the type in the British Museum I have associated with it the race that is prevalent 
in the Amazonian region and the Guianas. In case it is eventually found to be a synonym of one of the 
other, Felders name quadristrigata would stand. — d genitalia with harpes long, reaching well beyond base 
of uncus, stout, longer than broad, with apices rounded and armed with long, heavy marginal thorns *) (some 
curved and some straight) and differing in number on the two harpes, four on the right and five or six on the 
left; each harpe also with a very short, slender thorn from costa close to base; aedoeagus and penis as in 
festiva. (C. Heinrich.) 
S. avertina sp. nov. (74 f). Head and thorax wood brown; abdomen slightly paler. Forewings 
avellaneous, the darker shadings fawn colour; a narrow subbasal fascia; a fine line, almost medial, inbent, 
slightly outcurved across median; a black point at end of cell; a darker shade preceding postmedial, narrow 
from vein 3 to inner margin; postmedial outcurved below costa, fine, defined on basal side by pale scaling, 
partly white, followed between veins 3 and 5 by a dark patch; subterminal line black, fine, lunular near costa, 
and wavy, partly broken by veins; termen with an oblique pale shade from vein 3 across the subterminal line 
to vein 5. Hindwing wood brown suffused with hair brown; traces of a dentate line from apex, and subterminal 
blackish spots. Wings bellow avellaneous partly suffused with fawn colour. Forewing: costa dark reddish brown 
at base; a dark shade from costa crossing the black discal point; a fine postmedial line; subterminal spots 
above tornus. Hindwing: a black discal point, and a medial dark shade; postmedial line distinct, black, lunular 
dentate; subterminal black spots, two at vein ] larger. Expanse: 37 mm. Coatepec, Mexico.

d- Palpi obliquely ascending, thickly scaled, third joint almost porrect. Antennae pectinated to tips 
in type species the shaft fringed above with scales. Legs almost smooth ; hind tibiae with 2 pairs of spurs. Fore¬ 
wing: costal margin very convex towards apex which is subfalcate; the termen excised between veins 7 and 5, 
below 5 almost straight to tornus; veins 2 and 3 equally apart from 4; 4 and 5 from lower angle; 6 almost 
*) In this and other species of Sarsina, these ,,thorns“ are simply hooklike prolongations of the costa of the 
harpe and have nothing in common with the socketed modified spines found in some other families.
