and below vein 1; orbicular oval, oblique, outlined with black, open towards 
costa, filled with pale gray; claviform large, black, extending ™% across median 
space, reniform upright, large, hollowed out centrally on outer side, annulate 
with pale ochreous and black, more or less open towards costa, filled with light 
brown which shades into.smoky towards base; slight outwardly bent median 
shade, most distinct below reniform; veins 1 and 2 in median space sprinkled 
with whitish; t. p. line bent out below costa and slightly incurved in submedian 
fold, finely scalloped, followed by a pale shade line; subterminal space shaded 
with purple-gray; s. t. line prominent, yellow, indistinct at costa where it is 
defined by the contrast between dark subterminal costal patch and pale gray 
apical patch, bent sharply out at vein 7, then very even and parallel to outer 
margin with slight inward angle below vein 2; preceded by brown shading; 
terminal dark brown lunules and dusky fringes. Secondaries smoky, with darker 
terminal area and faint yellow terminal line, broadening below vein 2. Beneath 
smoky, apex of primaries and terminal border of secondaries somewhat darker; 
indistinct discal dots. Expanse 34 mm. 
Hasirat. White Mts., Ariz. 22. Type, Coll. Barnes. 
Belongs close to dodi Sm. but differs in the browner coloration 
and the entire lack of WW mark to subterminal line. We take pleasure 
in naming the species after the collector, Mr. E. Lusk. 
Porta (MAMESTRA) BICOLOR sp. nov. 
Head and thorax whitish gray, patagia heavily tipped and sprinkled with 
black; primaries largely blackish, suffused in places with white, maculation 
rather diffuse and indistinct; the ordinary lines are geminate, filled with white, 
which on account of the dark ground color alone shows clearly in most cases; 
subbasal line distinct, angulate; t. a. line outwardly inclined, dentate; orbicular 
outlined in white on dark ground, round; reniform large, more or less filled 
with white, with a darker lunate mark centrally; both spots preceded by white 
shading on costa; t. p. line dentate, rather evenly sinuate, followed above inner 
margin by a large patch of whitish, extending to s. t. line, semicircular in form; 
s. t. line indistinct, white, irregular, approaching outer margin on veins 3 and 4 
and slightly dentate, preceded by faint white scaling; fringes pale, checkered 
with smoky, more prominently in basal half. Secondaries in ¢ white, with 
apical smoky shading and dark terminal line; in 2 deep smoky, with pale 
fringes cut by a dark subbasal line not attaining anal angle. Beneath, in ¢ 
white, primaries heavily smoky in costal half of wing except costa itself which 
is narrowly white, powdered with smoky; secondaries slightly dusted with 
smoky along costa with small discal spot; terminal dark line to both wings; in 
@ whole of primaries smoky with slightly paler costa and traces of subterminal 
line; secondaries white, heavily sprinkled with smoky, especially apically, with 
discal dot and subterminal line. Expanse 29 mm,
