Antennae with scape cylindrical, very gradually and feebly clavate from base, not capitate, third segment straight, as long as scape in male, distinctly shorter in female; antennal tu bercles nearly contiguous ; elytra with basal gibbosity broad, feebly elevated, disk at base uniformly granulate-punctate (not granulate only on gibbosities) ; pronotllm armed each side with a robust tubercle. Moderate-sized, elongate-ovate, robust. Head with front slightly elongate, widened below lower margin of eye; genae elongate, vertical; eye with lower lobe oblong-ovate, subequal in height to gena.; antennal tubercles prominent, contiguous, armed at apex. Pronotum strongly transverse, narrowcd apically, armed latemUy with an' obtuse tubercle; disk with five small tubercles. Scutellum transverse.

86 THE TRIBE ONCIDERINI front occasionally nearly entirely dirty white pubescent, usually only with a vitta each side of that color. Pronoturn often with a number of irregular, whitish macu lae, especially basally and medially. Elytra whitish aclsperse, the markings often spurner on basal third. Body beneath black or piceous, donsely covered with dirty white pubescence, toward sides becoming yellowish and variegated with dark brown, medially with a number of glabrous, black maculae ; abdomen densely white or yellowish-white pubesc(;nt, toward sides tinged with ochraceous, each sternite with a band of irregular, black maculae, irregularly and densely placed, finer and sparser on fifth. Legs fuscous, hoary pubescent, more or less variegated with dark brown, sometimes dark brown punctate. Antennae black, covered with dark brown or fulvous pubescence, bases of four,th, sixth, and eighth segments broadly annulate with hoary, tenth and sometimes fifth narrowly so. Head minutely, densely punctate, with a few fine punctures interspersed, a median impressed line from occiput nearly to epistoma; front slightly elongate, widened from below and from above to just beneath lower margin of eye, deeply concave between antennal tubercles, minutely, rather densely punctate, a number of coarse punctures intermingled, especially medially; genae elongate, vertical, minutely, densely, and finely, sparsely, punctate; eye with lower lobe oblong-ovate, subequal to gena in height; antennal tubercles robust, prominent, contiguous, armed at apex with a short, vertical, obtuse horn, or long tooth. Pronotum strongly trans verse, sides irregular, gradually narrowed to apex, behind middle with a small, prominent, obtuse tubercle; apical and basal transverse sulcus straight, except at middle, the fonner deeper; disk with entire surface including sides rather coarsely, sparsely punctate, with a distinct, prominent tubercle behind middle, on each side with two smaller tubercles, the more basal one larger. Scutellum transverse, sides straight, strongly oblique, apex narrowly rounded. Elytra. gradually attenuate to apices, which are separately rounded; basal gibbosity feeble, disk basally rather densely granulate-punctate, the granules fine, the punctures coarse, the former dis appear behind basal fourth, the latter gradually become finer and sparser to apex; humeri prominent, the anterior margin feebly arcuate, slightly oblique, the angle with a large, projecting ,tubercle. Prosternum simple, moderately broad, slightly narrower to apex; mesosternal process short, broad, expanded posteriorly, apex deeply, bilobely emarginate. Fifth sternite slightly longer than fourth, apex subtruncate or feebly rounded. Procoxae with a prominent but small ,tubercle anteri oriy; femora rat.her robust, distinctly clavate, profemora with a short, longitudinal, slightly rugose ridge above :md below at base; metatibiae strongly expanded apic ally. Antennae about one and one-third times as long as body, the seventh seg ment attaining elytrai apex, sparsely fimbriate beneath on the four basal segments; sCfLpe elongate, at least attairung middle of pronotum, rather robust, feebly ex panded from base to apex, at base slightly rugose beneath; third segment as long as first, straight; fourth slightly shorter, rest subequal. FEMALE. A little more robust; antennal tubercles with a short tooth at apex; fifth sterrute one and one-half times as long as fourth, apex distinctly emarginate, with a median impressed line expanded into a triangular impression apically; pro coxae with a feeble tubercle anteriorly; profemora without ridges at base; meta tibiae slender; antennae about as long as body, segments from fourth gradually shortened.
