NO. 3561 LOXOSTEGE—CAPPS Di 
In FuicHt.— April to September. 
Remarks.—See the discussion of pergilvalis (p. 24). 
Loxostege cochisensis, new species 
FIguREs 39, 82, 121 
Maur.— Alar expanse 21-26 mm. Frons conical. Antenna weakly 
ciliate. Midtibia slightly more incrassate than hind tibia; hair- 
pencil obsolescent or absent. Outer spur one-half as long as inner. 
Resembles pergilvalis but with ground color usually more ochreous 
and transverse lines of forewing slightly smoother: postmedial line 
of hindwing absent, or if evident, smooth, somewhat diffuse, termen 
concolorous with fringe. 
Genitalia (fig. 39): Uncus somewhat narrower apically. Harpe 
with digitate setae; outer half of dorsal margin of sacculus somewhat 
produced, with numerous, short inwardly directed spines. Aedeagus 
without cornuti. 
Fremate (fig. 121) —Alar expanse 19-26 mm. Similar to male in 
color and maculation. Genitalia (fig. 82): postgenital plate strongly 
sclerotized, concave, with distinct transverse ridges. 
Typr.—Male, U.S. National Museum, USNM 67609, genitalia 
slide OBP 147. 
Typr-LocaLity.—Palmerlee, Ariz. 
Paratypes.—Arizona: type-locality, 1 9; [no additional locality], 
2 9; Santa Rita Mts. 1 o, 1 9; Southwestern Res. Sta., Chiricahua 
Mts., Cochise Co., 1 o&, 2 9; Madera Canyon, Santa Rita Mts., 2 0, 
3 9; Madera Canyon, Santa Rita Mts., Pima Co., 4 9; Huachuca 
Mts., 1 9. Texas: The Basin, Chisos Mts., Brewster Co., 2 o, 1 9. 
Paratypes in the U.S. National Museum, Los Angeles County Mu- 
seum, and the collection of Mr. C. P. Kimball. 
Foop pLant.— Unknown. 
In Fuicut.—June to September. 
Remarks.—The narrower uncus, in combination with the character 
of the spinulation on the dorsal margin of the sacculus, is diagnostic 
for the male genitalia of cochisensis. The character of the postgenital 
plate (concave with transverse ridges) distinguishes the female geni- 
talia of cochisensis from all others of the genus. 
Loxostege jacalensis, new species 
Fiaures 38, 134 
Ma se (fig. 134).—Alar expanse 21 mm. Frons conical. Antenna 
weakly ciliate, cilia about one-half as long as width of shaft. Midtibia 
weakly incrassate; hair-pencil absent or obsolescent. Outer spur 
slightly less than one-half as long as inner. Similar to cochisensis in
