about one-fourth wider than apex; with an apical and basal sulcu3, basal oblique
laterally ; disk with five tubercles, the median from base to middle, elongate, moder­
ately elevated, two either side of middle and iust behind apical sulcus, slightly more
elevated than median onc; base with few punctate granules. Scutellum very trans­
verse; sides straight, oblique; apex subtruncnte, notched medially. Elytra feebly
attouuate, with sides nearly straight to apices which are separately rounded; at
base either side with a very broad, moderately elevated gibbosity, apical half of the
gibbosities with a row of several very distinct punctate-granules at middle, re­
mainder of bnse with coarse, deep, well-spaced punctures, toward apices they
become smaller; humeri prominent, anterior margin arcuate, angle obtusely rounded,
not tuberculate, a short, feebly elevated carina extending posteriorly from humeral
angle. Prosternum not widened behind middle ; mesosternal process notched deeply
at apex; fifth sternite about one-fourth longer than fourth, truncate at apex. Pro­
coxae globose, with a short, robust tooth anteriorly; profemora nearly parallel on
basal two-thirds, thence feebly clavate to apex, transversely rugose on dorsal and
ventral sides on basal two-thirds; other femora more suddenly c1avatc; metatibiac
much widened on apical half ; protarsi much dilated. Antennae with seventh
segment attaining elytral apex, remaining segments missing ; scape robust, reach­
ing just beyond middle of pronotum, nearly capitate apically, at basal half laterally
with deep grooves, dorsally rugosc, apical portion densely, finely punctate; third
segment moderately slender, sinuate, about onc-si:..1:.h longer than scape; remaining
segments gradually shorter ; scape thinly, third and fourth moderately fimbriate,
slightly so on fifth, sixth, and seventh.
FEMALE. Antennal tubercles very feebly produced ; fifth sternite about two­
thirds ngnin as long as fourth, feebly emarginate, broadly triangularly impressed
at apex, either side at apex tufted; procoxae globose, with a feebly elevated, obtme
tubercle; pro£emora gradually clavate, not rugose dorsally and ventrally; metatibiae
less dilated; antennne about as long as body; scape slender, reaching not quite to
middle of pronot-um, very feebly rugose basally, not grooved.

PLATE II, FIGURE 10.
A little larger in form than H. nesiope; elytra with whitish
mottling indistinct and confused, sides not vittate, humeri more
projecting, angle with a large, obtuse tuhercle; antennae with third
segment only a little longer than seape, slightly bisinuate; metafe­
mora and metatibiae less distinctly annulate; abdomen medially
thinly gray and brown pubescent, rough in appearance ; antennae
not distietly annulate from fourth segment.
