NO. 3561 LOXOSTEGE—CAPPS 3 
wedgelike accentuation of the veins at the termen in venadialis dis- 
tinguishes its females from those of well marked specimens of mel- 
linialis; if specimens are worn, the genitalia must be examined for 
the reliable separation of those two species.

Maue.—Alar expanse 16-20 mm. Conical production of frons 
obsolescent or absent. Antenna weakly ciliate. Midtibia weakly 
incrassate; hair-pencil weak. Outer spur one-fourth as long as inner 
spur. Head, thorax, and abdomen ochreous. Ground color of wings 
pale ochreous, markings dark brown with reddish tinge. 
Genitalia (fig. 58): Uncus triangulate, apex pointed, slightly blunt. 
Harpe rather narrow, with digitate setae, clasper short, stout, curved, 
spinulate distally; sacculus with conspicuous upturned slender spine 
arising from dorsal margin. Anellus stout. Aedeagus with subequal 
bifurcate sclerotization and patch of deciduous spines. Large element 
of bifurcation elongate, somewhat concave, dilated distally; small ele- 
ment a short, spurlike projection from near base of larger. 
FEMALE (fig. 140).—Alar expanse 20-23 mm. Color and macula- 
tion as in male. Genitalia (fig. 102): ostial pouch large, width about 
equal to depth; ductus bursae extending beyond anterior margin of 
pouch.

SPECIMENS EXAMINED.— 39. 
In Fiicut.—July to September. 
Remarxs.—The spurlike projection of the aedeagus varies from 
obsolescent to well developed, and the serration of the margins of the 
larger element ranges from nearly smooth to distinctly serrate. The 
ostial pouch is also somewhat variable in shape, particularly adjacent 
to the origin of the ductus seminalis.
