NO. 3561 LOXOSTEGE—CAPPS 41 
Hulst, Type,” but this appears to be a manuscript name since no 
record of its description was found in the literature. 
Dyar erred in referring to the tibiae and tarsi as black; only the 
tarsi are blackish. The tibiae are brownish yellow. 
Loxostege sinaloensis, new species 
Fieure#s 13, 150 
Mate (fig. 150).—Alar expanse 15-17 mm. Frons conical. An- 
tenna weakly ciliate, somewhat pubescent, brownish yellow with tip 
white. Midtibia weakly incrassate; hair-pencil obsolescent or absent. 
Outer spur one-half as long as inner spur. Upper surface of wings 
brownish yellow, unicolorous; under surface same as upper, except 
costa of forewing narrowly margined with black. Labial palpus with 
all segments brownish yellow. Entire foretarsus fuscous; first seg- 
ment of mid- and hind tarsi pale fuscous, remainder of segments 
brownish yellow. 
Genitalia (fig. 13): Uncus bluntly pointed. Harpe without digi- 
tate setae; clasper bifid. Aedeagus with one large, conspicuous, 
hookhke distal cornutus and a few patches of small, slender spines; 
basal keel well developed.

Remarks.—L. sinaloensis and subcostalis are closely related; but 
the differences in coloration of the antenna, third segment of the 
labial palpus, and tarsi readily distinguish them from each other. 
The genitalia of both stnaloensis and subcostalis resemble those of 
helmialis and pseudohelvialis, but the former two species have stouter 
bifid claspers of the harpe and a different aedeaga! armature.
