Foop pLtant.—Unknown. 
In ruicHT.—April to October. 
Remarxs.—L. fordi resembles helvialis and polingi in color and 
maculation, but in well-marked specimens of fordi, a faint subterminal 
line, absent in both helvialis and polingi, is discernible on the forewing. 
Differences in the lengths of the outer spurs distinguish the males of 
these species from each other; in helvialis, the outer is one-half as long 
as the inner; in polingi, it is about one-third as long as the inner; and 
in fordi, it is much shorter, only about one-fifth as long as the inner 
one. ‘The females are reliably distinguished only by examination of 
the genitalia. 
Loxostege alpinensis, new species 
Figures 19, 83, 108 
Mate (fig. 108).—Alar expanse 20-23 mm. Frons conical. An- 
tenna weakly ciliate. Outer spur slightly less than one-half as long 
as inner spur. Color and maculation as in fordi but with markings 
often more obscure. 
Genitalia (fig. 19) resemble those of fordi but with outer group of 
spines smaller and spinules weaker; inner group in a linear arrange- 
ment, extending from near base of outer group to middle of sacculus. 
Frema.e.—Alar expanse 21-23 mm. Color and maculation as in 
male. Genitalia (fig. 83) somewhat similar to those of fordi but with 
median production of ventral margin of ostium broader, not crinkled 
laterad ; origin of ductus seminalis more remote from ostium.
