A little smaller than H. apache Banks, and not closely 
resembling any other species of Hesperoleon. 
Hesperoleon infuscatus, new species 
Figures 4, 39, 40, 44, 45 
Face pale, antennal band straight-margined below, with 
a thin line extending toward clypeus. First vertex row far 
forward, a strongly curved band, separated medially from 
antennal band by a pale spot; in most specimens the ends 
fused with antennal band. Second vertex row often connect- 
ed medially with first, consists of an irregular, medially 
thickened band each side, often connected. Labial palpi 
slender, the apical segment slender, pointed, shiny-fuscous; 
maxillary palpi dark. Scape dark below, pale above ; pedicel 
dark, flagellum dark, last ten (more or less) segments with 
broad apical pale bands on ventral side. Pronotum distinct- 
ly broader than length at center, submedian stripes fairly 
straight; laterals very wide behind furrow, narrowly sepa- 
rated from medians by pale, before furrow narrow and 
curving to fuse with medians at anterior margin. Space 
between bands suffused with fuscous at, and sometimes 
behind, furrow. Submarginal stripe a thin line curving back 
from furrow, often absent. Mesoscutellum with two long, 
well-separated dark stripes, metascutellar stripes fused for 
about two-thirds their length. Coxae pale medially, dark 
laterally; fore femur dark-striped posteriodorsally, mid 
and hind femora wholly dark but for ventral pale stripe. 
Fore tibia infuscated posteriorly with dark subbasal and 
apical bands ; mid tibia with dark basal, subbasal, preapical, 
and apical bands ; hind tibia with subbasal and apical bands, 
and a thin ventral dark line. Tarsal segments pale, dark- 
banded apically, segments three and four more so than 
others. 
Abdomen ( $ ) : dark, with dorsal pale stripe each side 
extending to sixth segment. Ectoprocts long: (about 1 % 
times as long as 8th abdominal tergite, which is short, 
1.3 times as long as high) extend straight back, viewed 
from side; from above, bent into lyriform curve. Mediuncus 
arms spread widely; parameres form a flat plate from the 
lateral margins of which the hooks emerge and bend
