tooth or short horn which is obtuse at tip. Pronotum distinctly transverse, sides
nearly straight, gradually narrowed to apex, with a small but distinct tuoorde
behind middle, directed slightly forward; apical transverse sulcus deep, widened
laterally, basal one interrupted at middle, usually appearing more or less as It
transverse fovea each side, only indistinctly connecting with the oblique lateral
sulci; disk with an elongaw, rather feeble median tubercle and It prominent, glo­
bose ODC side, these obliquely impressed and each more or less subdivided into two;
without distinct punctures. Scutellum tran.:."Verse, sides straight, strongly oblique
(rarely only feebly so), apex broadly and feebly rounded, slightly impressed at
middle. Elytra with sides more or less straigbt, tapering to apices, which are
separately rounded; base each side of suture wlth a brood, rounded gibl:lo>!ity, which
is sparsely and uniformly covered with moderate size granulate-punctures, the
impres':uoIlB of which are deep, the elevations feeble, lateral and posterior to the
gibbosity coarsely, sparsely punctate, punctures extending to apex but finer and
morc obsolete posteriorly, apical third with several feeble costac; humeri only
slightly prominent, anterior margin straight, a distinct tubercle at angle, from
which runs posteriorly und slightly obliquely a feeble carina terminating at about
basal quarter of elytron; sides behind humeri very coarsely and densely punctate to
the fascia. Prosternum simple, or with a. very faint trace of a transverse carina
between coxae. Procoxae tumid posteriorly, with a short but distinct, :lcute
tubercle anteriorly, the apex of which is slightly curved; femora robust, clavate,
the metafcmora less distinctly 50, the profemors more robust ba:mlly and, con­
sequently, more feebly clavate, tralli>-versely rugose beneath; metatibiac strongly
swollen, the anterior face impressed and punctate. Fifth sternite slightly longer
than fourth, apex cmarginate. Antennae a little longer than body, densely fimbriate
on third and fourth segments, thence sparsely 60 to apex; scape somewhat
capitate after middle, basal half slender, transversely rugose beneath; third seg­
ment strongly bent basally, very indistinctly reeurvcd apically ; eleventh segment
slightly longer than tenth, processed apically.
FEl-lALE. Front not rugose and impressed only feebly near mouth; antennal
tubercles ending in a very short, broad tooth; proooxae unarmed; profemora less
robust basally, not rugose beneath, metatibiae not swollen; fifth sternite twice
length of fourth, broadly flattened apically, not impressed, apex: truncate; antennae
slightly shorter than body, scape not rugose oolleath, eleventh with a very short
process.
