Description: Rostra of both sexes piceous, covered with light 
brown scales from base to near apex; stouter and slightly more curved 
in male than in female. Head black to piceous; front closely covered 
with light brown scales. Antennae piceous; club reddish brown in 
some specimens. Prothorax moderately rounded at sides, closely 
covered by broadly ovate and narrow scales, which are yellowish 
brown except for a white median vitta which extends from base to 
near middle of disk, and a similar vitta on each side; prosternum very 
shallowly concave. Setiform scales as in group description. 
Scales of elytra very broadly ovate, subtruncate at their tips, 
medium brown to yellowish brown except for an irregular median 
white patch. Scales of ventral side of thorax and abdomen yellowish 
gray, slightly smaller and more rounded than the scales of the elytra. 
Femora moderately clavate, dark reddish brown, covered with a 
mixture of ovate and elongate-ovate pale brownish scales. Tibiae red- 
dish brown, covered with closely spaced rows of elongate white to tan 
scales. Tarsi piceous; fourth segment extending well beyond third; 
claws connate for slightly less than half their length and slightly 
divergent. Median lobe of male genitalia rather broad, subparallel 
at sides, the internal sac covered with small spines; spiculum gas- 
trale fairly straight; dorsal “wing” at anterior end fairly well devel- 
oped (fig. 68).
