Hypsioma signaticornis Thomson, Physis, 11, 1868, p. 48.
Elytra with median fascia pale, irregular ; at base moderately
punctate, not rugosely so ; antennae with third segment on surface
entirely piceous, DOt pale, but annulate with hoary pubescence,
remaining segments testaceous at base j eye with lower lobe subequal
in height to gena.
FEMALE. Elongate-ovate, robust, convex; head and humeri piceous, prollotum
nearly fuscous, elytra and scutellum dark reddish-brown. Head and pronotum
covered with pale ochraceous-gray pubescence, rather indistinctly mottled with
brown. Scutellum ochr.'lceous-gray pubescent. Elytr.'l covered with light and dark
gray-brown variegated pubescence, extreme base pale ochraceous-gray, with an
irregular, oblique, broad line of whitish running from middle of lateral margin
posteriorly to apical third of suture, behind thi s line are several strc.ll .ks and spots
of the same color, the streak along suture e:\1:ending interruptedly to apex. Body
beneath fuacous, thinly ochraceous-gray pubescent, medially hoary pubescent;
abdomen medially broadly and sparsely covered with ochraceous and brown variegated
pubescence, laterally ochraceous vittate, vittae narrower on first and second
sternites. (The exact coloration of the abdomen could not be determined, due to
a resinous deposit on the lower surface; the very middle portion might be nearly
glabrous and more or less shining.) Legs fuscous, covered with pale grayish pubescence,
mottled with dark brown; meso- and metatibiae indistinctly annulate with
ochraceous; tarsi hoary pubescent, claw segments with only apical fourth piceous,
rest bright rosy-yellow. Antennae fuscous; basal quarters of fourth and sixth
segments, basal thirds of fifth and seventh, two-fifths of eighth and ninth, nearly
half of tenth and more than half of eleventh bright rosy-yellow annulate; first
and second segments, basal two-fifths of third, and pale bases of remaining segments
hoary-gray pubescent, apices from third dark brown pubescent; extreme apex
of eleventh tufted with golden.
Head minutely and densely punctate, with a median impresed line from
occiput nearly to epistoma; front finely punctate, with a number of coarse punctures
interspersed; genae vertical, sparsely pubescent, sculpture similar to that of
front; eye with lower lobe broadly oblong-ovate, its height subequal to that of
gena; antennal tubercles prominent, slightly remote, at apex feebly produced.
Pronotum transverse, sides straight, tapering from base to apex, unarmed · ; apical
· transverse sulcus deep, arcuate, basal one also deep but straighter, coalccent with
the lateral oblique ones; disk at middle on basal half with a distinct oval tubercle,
on each side of and slightly anterior to which are two equally elevated tubercles,
the most lateral ones oblique; entire surface minutely punctate. Scutellum trans·
verse; sides feebly arcuate, strongly tapering posteriorly; apex with the lateral
