Genitalia (fig. 35): Harpe with distal termination of oblique ridge- 
like modification pointed, curved, hooklike, and nonscobinate; a 
similar hook at base of cluster of digitate setae; sacculus with two 
conspicuous spines, one to several small, short spines often associated 
with outer. Aedeagus with distal patch of subconical granules. 
Fremate (fig. 136).—Alar expanse 26-28 mm. Color and macula- 
tion as in male. Genitalia (fig. 85): shape of ostium and character 
of its ventral margin is diagnostic for females; ostium somewhat 
variable, nearly round to distinctly oval, ventral margin smooth.

Hist.), and the Canadian National Collection. 
Foop pLant.—Unknown. 
In FuigHT.—April to October. 
Remarks.—L. cayugalis is likely to be confused in collections with 
the species described as Pachyzancla cynoalis Druce, which is treated 
next herein. One of the cayugalis paratypes from Cachi, and those 
from San Geronimo and Cuernavaca, are from the syntypes of cynoalis. 
Loxostege cynoalis (Druce), new combination 
FicureEs 36, 72, 137 
Pachyzancla cynoalis Druce, 1895, in Godman and Salvin, Biologia Centrali- 
Americana, Zoology, Lepidoptera, Heterocera, vol. 2, p. 221 [in part]. 
Mate (fig. 137).—Alar expanse 23 mm. Frons conical. Antenna 
ciliate, cilia about as long as width of shaft. Upper spur about 
one-fourth as long as inner spur. Color and maculation similar to 
that of cayugalis. 
Genitalia (fig. 36): Harpe with production from base of digitate 
setae strongly denticulate; dorsal margin of sacculus with two con- 
spicuous, stout spines. Anellus stout. Aedeagus with distal patch 
of small conical granules. 
Fremate.—Alar expanse 20-21 mm. Similar to male in color and 
maculation. Genitalia (fig. 72) resemble those of neomarculenta but 
with contour of ductus bursae undulate between ostium and origin 
of ductus seminalis. 
Lecroryrr.—Male, British Museum (Nat. Hist.), genitalia slide
