 point below cell, then outcurved to inner margin, followed in eel! by a black 

 point; a black spot on discocellular; postmedial coarse, black, outbent on costa, 

 finer, outcurved and dentate between veins 5 and 3, inset at vein 3 and some- 

 what macular the spot on submedian told inset; some subterminal darker shad- 

 ing; a thick black terminal macular line; cilia cupreous olive. Hind wings 

 semihyaline white, the termen broadly fuscous at apex narrowing towards anal 

 angle; buff hairs on inner margin. Fore wings below to postmedial white, the

Habitat. Yahuarmayo, Peru. 



Type Cut. No. 25681, U. S. N. M. 



This species looks very much \ike-Homura nocturrtalis Lederer, 

 which I think is a Macalla, though Hampson placed it in Locas- 

 tra, but he could not ha\'e known Lederer's species as he made 

 H. trisnlcata \\'arren a synonym of it. H. tnsulcata is i|uite a 

 different species and has priority over Locastra -ciriditinctci Schaus, 

 the latter having been described from a very fresh and heavily 

 marked specimen. 



Macalla afflicta, new species. 



Male. Palpi laterally vinaceous rutous, slightly mottled with black near tip. 

 Vertex vinaceous cinnamon with some white mottling; collar similar with con- 

 siderable black scaling. Thorax mottled in the three colors, the white pre- 

 dominating. Abdomen above white at base, then olive gray, with brown 

 shading on terminal half, but varying considerably in different specimens. Fore 

 wings mostly silvery whitish gray; a basal darker line outbent on inner margin; 

 subbasal space whiter in cell and on inner margin, with broad scales ripped with 

 salmon buff; whiter scales forming a fine, vertical, antemedial line; a medial 

 In-own line slightly outcurved mottled with fuscous below cell to inner margin; a 

 brown spot on costa above discocellular, from it a fine black line curved around 

 end of cell, broader below cell, shaded with brown almost suffusing with medial 

 line, outbent on inner margin; sometimes these two lines are clearer, without 

 the brown shading; subterminal line double, slightly outbent on costa and finely 

 dentate, inbent on vein 2 and downturned to inner margin, preceded from . 

 to vein 4 by a brown shade, and followed by a similar shade to termen and apex; 

 a brown and fuscous spot before the subterminal from vein 2 to below vein 1; 

 terminal fuscous spots on intersp ha buff white with fuscous spots at 



veins. Hind wings semihyaline yellowish white; termen fuscous from ape\ 

 narrowing to a line below vein 2. Fore wing below silky fuscous, the inner 

 margin broadly whitish; a darker subterminal shade; a terminal black line; cilia 

 white with black spots; costa shaded with rutous. Hind wings below whiter; a 

 fuscous shade at apex; the costa shaded with rutous; traces ot a subterminal 

 punctiform line to vein 2.
