lined dark brown ; two dark fuscous dots transversely placed on 
end of cell; a marginal series of dark fuscous dots round apex and 
termen : cilia whity-brownish (imperfect). Hindwings 3 and 4

Stenoma leucocryptis, n. sp. 
c? . 28 mm. Head fuscous, forehead mixed pale metallic-green, 
face whitish. Palpi grey. Antennal ciliations nearly 1. Thorax 
rather dark purplish-fuscous. Abdomen dark grey, suffused indigo 
towards apex, beneath white except towards apex. Forewings 
very elongate, costa gently arched, apex obtuse, termen slightly 
rounded, hardly oblique ; 2-4 closely approximated at base, 7 to 
apex (indefinite) ; uniform rather dark purplish-fuscous : cilia grey. 
Hindwings nearly twice as broad as forewings; blackish-fuscous; 
cilia grey, a darker subbasal shade. Hindwings beneath with large 
white patch occupying basal but above 8 narrowed to 
Colombia, Medina, 1650 feet ; 1 ex. Probably allied to subita. 
Stenoma mustela Wals. 
c? . 19 mm. Antennal ciliations Forewings with pale ochreous 
subdorsal hairpencil from base beneath, covered by a broad rather 
even costal expansion of hindwings from base to beyond middle, 
fringed with rough hairscales. 
Panama, Lino, 2650 feet; 1 ex. (Vienna Mus.). Walsingham’s 
description is drawn from a single female only. 
Stenoma iopetra, n. sp. 
£. 24 mm. Head indigo-grey. Palpi dark indigo grey. 
Antennal ciliations Thorax whitish-grey-ochreous. Abdomen 
rather dark grey (above and beneath). Forewings elongate-oblong, 
costa gently arched at extremities only, apex rounded-obtuse, termen 
slightly rounded, nearly vertical; 2-5 approximated, 7 to apex 
(indefinite) ; smooth light greyish-ochreous, dorsal |- greyer and 
violet-tinged : cilia light greyish. Hindwings dark grey; cilia 
grey, a darker subbasal line. 
Guatemala, Cayuga, August (A. BuscJc)-, 1 ex. This example 
was kindly sent me by Mr. Busck under the name of ianihina Wals., 
but though superficially similar cannot be that species, as ianthina 
is described as having a long pale ochreous hairpencil from base of 
hindwings above (which this example certainly has not) and is 
therefore an Antaeotricha ; the colour also of both forewing and 
hindwing differs, though both species are without markings, and 
the antennal ciliations are also different. 
Stenoma spermidias, n. sp. 
2 . 35 mm. Head pale brownish-grey. Palpi light grey, base 
whitish. Thorax lilac-fuscous. Forewings rather broad, slightly
