PLATE IH, FIGURE 3.
From H. opalina, which it resembles in lacking a tubercle on the
humeri, it differs in elytra having on disk at base more granula­
tions than pUDctations (the opposite being true of opalina) ; basal
gibbosities shorter, less elevated, and less compressed, their pos­
terior ends nearly attaining suture; humeri with anterior margin
nearly straight, strongly oblique, at angle truncated j Pl'Ollotum
with discal tubercles less elevated j fifth sternite entirely pale pu­
bescent (although thinly so) ; eye with lower lobe broadly ovate,
small, distinctly sborter than gena (only five-eighths height of
gena) ; front distinctly narrowed between eyes j and scape less
robust.
F£MALY.. Elong:l.te-ovn.le, rather sleuder, subcylindric:1.l, elytra subconvex ;
blnekish to brownish-olive; entirely gray pubcsceut, spotched with light brown on
greenish-brown pubesccnce. Scutellum with :1. mrrow, gla.brolls vitta medially.
Beneath dark brown, irrgulnrly clothed with whitish pubescence interspersed with
SInall, glabrous area; abdomen glabrous, shining at middle, laterally white vittate
except on fifth stcrnite where it is ne:l.fly entirely whitc Jlube:!cent. Legs and
antennae dark brown ; legs thinly gray pubescent, femora. with a rather small, indistinct
brownish patch dorsally at apex. Antennae with SCllpe thinly gTllY pube­
scent and with a small, brownish spot dorsll.lly at apex; third segment with bnsal
haIf gray and apical half brownish; remaining segments with basal third gray,
remainder brownish.
Head above fiuciy, densely PIlnct:lte, :\ median imprc.'1I, n
