color and markings. Genitalia (fig. 38) similar to those of cochisensis 
but with uncus stouter, fewer spines on dorsal margin of sacculus, 
spines coarser, anellus broader basally, outer margins of lateral arms 
parallel or nearly so.

FIGURE 48 
Maur.—Alar expanse 20 mm. Frons conical. Antenna weakly 
ciliate, cilia about one-half as long as width of shaft. Outer spur 
one-fourth as long as inner. Similar to jacalensis in color and macu- 
lation, but somewhat paler. Genitalia (fig. 48) resemble those of 
pseudobliteralis but harpe without digitate setae, pad broader with 
spinulation finer, aedeagus more robust, cornutus stronger.

p. 281. 
Maue.—Alar expanse 20-24 mm. Frons conical. Midtibia 
incrassate, hair-pencil distinct. Outer spur one-third as long as inner. 
Resembles nayaritensis in color and maculation but somewhat paler, 
subterminal line present on forewing. 
Genitalia (fig. 41): Harpe without digitate setae; dorsal margin of 
sacculus straight or nearly so, extending almost to middle of harpe. 
Aedeagus with a rather large patch of spinelike cornuti. 
Frema.e (fig. 115)—Alar expanse 18-25 mm. Similar to male in 
color and maculation. Genitalia (fig. 93): postgenital plate strongly 
sclerotized, concave, scobinate. Sclerotized part of ductus bursae 
between ostium and origin of the ductus seminalis about as wide as 
long; ductus bursae rather conspicuously enlarged adjacent to origin of 
ductus seminalis, with longitudinal grooves.
