Loxostege fuscivenalis (Schaus), new combination 
Figure 177 
Lygropia fuscivenalis Schaus, 1920, Proc. Ent. Soc. Washington, vol. 22, no. 8, 
p. 213.—Klima, 1939, in Junk, Lepidopterorum catalogus, pt. 94, p. 233. 
Mats (fig. 177).—Alar expanse 23 mm. Frons conical. Antenna 
somewhat pubescent, cilia very short. Outer spur one-third as long 
as inner spur. Head and collar orange; patagia orange anteriorly, 
fuscous posteriorly; abdomen fuscous. Forewing dull grayish brown, 
without markings except for brownish fuscous accentuation of veins. 
Hindwing brownish fuscous, accentuation of veins black. Labial 
palpus: first segment orange; upper half and distal portion of second 
segment fuscous, remainder orange; third segment fuscous. 
Genitalia similar to those of the species treated next but with vin- 
culum narrower and anterior production longer.

SPECIMENS EXAMINED.—2. 
Remarxs.—L. fuscwenalis is definitely misplaced in Lygropia and 
its affinity to this group is remote. Although the genitalia of fusci- 
venalis are somewhat aberrant, all other characters indicate that it is 
closely related to Loxostege. 
Loxostege peruensis, new species 
FiagureE 178 
Matz (fig. 178).—Alar expanse 24 mm. Frons conical. Antenna 
somewhat pubescent, cilia very short. Outer spur one-third as long 
as inner spur. Head, collar, palpi, and abdomen entirely fuscous. 
Fore- and hindwings as in fuscivenalis. 
Genitalia: Uncus short, broad at base, distal termination a sharp 
point. Harpe without digitate setae; two slender fingerlike projections 
dorsad of outer end of sacculus, one directed dorsad, the other ventrad ; 
sacculus with a conspicuous medial production bearing a cluster of 
strong spines. Aedeagus with two subequal sclerotizations; the long 
one narrow, straplike, with distal termination a long, slender, curved 
hook, the other short, bluntly pointed distally.
