Foop puant.—Unknown. 
In FLIGHT.—June to September. 
Remarks.—Labels on some specimens indicate that neohelmalis 
has been confused with both mancalis and helvialis. The lack of a 
subterminal line on the fore- and hindwings of neohelvialis distinguishes 
it from mancalis. The sparser cilia of the antenna and incrassate 
midtibia with a hair-pencil distinguishes the males of neohelvialis from 
those of helvialis. If the specimens are in good condition, the colora- 
tion along the outer margin of the fore- and hindwings is darker in 
neohelvialis than in helvialis; in the former, it is concolorous with the 
markings of the wings and in the latter, concolorous with the ground 
color of the wings. Worn females of neohelvialis, however, are reliably 
distinguished from those of helvialis only by examination of the 
genitalia. 
Loxostege nayaritensis, new species 
FicureEs 10, 65, 117 
Mate.—Alar expanse 25 mm. Frons conical. Antenna weakly 
ciliate, cilia one-half or less than one-half as long as width of shaft. 
Midtibia incrassate, hair-pencil present. Outer spur about one-third 
as long as inner one. Resembles both pseudohelvialis and arizonensis 
in color and maculation; in nayaritensis, markings darker and browner 
with indentation of transverse posterior line of forewing more directly 
inward at vein 3 and coloration of reniform extending somewhat be- 
yond lower angle of cell between veins 3 and 4; hindwing with a 
similar but smaller patch. 
Genitalia (fig. 10): Like those of arizonensis but with padlike 
production broader, more rounded, and setae more numerous; sac- 
culus without a spine midway between outer cluster of spines and 
base of anellus; vinculum more broadly concave midventrally. 
Fremate (fig. 117)—Alar expanse 22 mm. Similar to male in 
color and maculation except that transverse posterior line of forewing 
is somewhat straighter from costa to vein 3 and small brownish patch 
between veins 3 and 4 at lower angle of cell stronger; these differences 
are not likely to be constant in a larger series. Genitalia (fig. 65) 
with midventral modification of ostium narrow, not interrupted; 
ductus bursae conspicuously enlarged at origin of ductus seminalis.
