32 THE TRIBE ONCIDERINI
in markings, humeri more projecting, with a large rounded tubercle
at apex ; procoxae in male with a small, distinct tubercle j metati­
biae very strongly expanded in male, not distinctly annulate j all
femora distinctly annulate on anterior face; abdomen medially
gray and dark brown pubescent, the former predominating j an­
tennae with scape more robust in male; eye with lower lobe as
long as gena in male.
MALE. Elongate-ovate, robust; fuscous, densely covered with hoary or pale
fulvous-gray pubescence on head, pronotum, scutellum, and basal sixth of elytrn.
Head with six irregular, brown vittae, one each side of middle and two less
distinct ODes behind each eye; front largely dark brown pubescent, hoary bima­
culate at center, and slightly variegated above with same color. Pronotum tinged
with brown and fulvous, slight.ly mottled wit.h brown, leaving two viUae on each
side and a lilllaU macula each side of middle toward base, hoary. Scutellum slightly
tinged with fulvous. Elytral base only feebly tinged with fulvous; surface. from
basal si."tb dark brown pubescent, sparsely sprinkled witb fine, hoary dots, which
often coalesce to form irregular lines. Body beneath dark reddish-brown to fuscous,
sparsely hoary pubescent medially, laterally broadly fulvous or becoming brownish;
abdomen medially gray and dark brown, the former predominating. Legs as in
chaseba but all femora annulate (or banded) wit.h fulvous on anterior faces.
Antennae as in the saille species.
Head above minutely, densely alutaceousj front elongate, only slightly nar­
rowed between eyes, narrowly concave between antennal tubercles, a few fine
punctures showing between pubescence; gcnae elongate, vertical, broader than in
chaseba; eye with lower lobe elongate oblong, equal in height to gena ; antennal
tubercles robust, prominent, slightly ",eparated, armed at apex with a long tooth.
Pronotum as in chaseba. Scutellum nearly semi-circular. Elytra distinctly at;..
tcnuate to apices, which are separately, broadly rounded; basal gibbosities broader
than in chaseba, the granules finer, very fine near suture, appearing nearly as punc
tures there; humeri distinctly, but slightly projec:ting, anterior margin straight,
oblique, lingle with a large, rounded tubercle, the carina very short or obsolete.
Prosternum simple, rather narrow; mesosternal process broad, slightly transverse,
apex deeply emarginat.e. Fifth sternite one-half longer than fourth, apex broadly
truncate. Procoxae with a smail, distinct tubercle; femora rather slender, slightly
clavate, profemora very robust, subeylindrieal, finely rugose on lower and upper
faces ; metatibiae strongly expanded apically. Antennae longer than body (want;..
ing from sixth segment) scape attaining apical third of pronotum, robust, strongly
and gradually clavate from base, coarsely rugose on basal half; third segment two­
fifths longer than scape, distinctly sinuous.
FEMALE. More robust than male; front broader; antennal tubercles less
prominent, nearly unarmcd; eye with lowcr lobe shorter than gel1a ; elytra less
strongly tapering to apices; fifth stamite nearly twice length of fourth, slightly
emargina.te at apex, strongly impressed medially ; procoxae slightly tumid anteriorly,
not tubereulate; profemora slender, clavate, not rugosej metatibiae not much
expanded apically; antennae slightly shorter than body, scape clavate on apical
half, slender basally, not rugose.
LENGTH 15-16 mm.; width 6.5-7 mm.
