LAWRENCE S. DILLON <strong>AND</strong> ELIZABETH S. DILLON 31 cave between antennal tubercles, minutely, densely alutaceous, nearly impunctatcj genae elongate, verticle, minutely, densely alutAcous and obsoletely punctate; eye with lower lobe broadly oblong, about two-thirds the height of gena ; .'l.ntennal tubercles robust, prominent, slightly separated, anned at apex with a robust, acute tooth. Pronotum strongly transverse; sides nearly straight, distinctly tnpering to apex, feebly tuberculate behind middle; apical transverse sulcus sinuous, shallow, baSilI one more distinct, straight, coalescent with the lateral oblique ones ; disk with five distinct tubercles, median one less strongly elevated, subbasal, rest slightly elonga.te, arranged in a curved line anteriorly, the members of e.'l.ch pair more or less connected by a. tumid area between them. Scutellum transverse; sides straight, oblique; apex broadly arcuate or subtruncate, Eometimes finely notched and slightly depressed medially. Elytra strongly attenuate to apiees, which are separately, broadly rounded; basal gibbosity prominent, elongate, narrow, studded along its apex with a row of large granules, rest of disk at base ratber coarsely, sparsely punctate, a few punctures, especially near scutellum, bear ing fine granules, behind middle finely punctate, thence smooth to apex; humeri very prominent, anterior margin broadly arcuate, oblique, angle with a large, sligbtly projecting tubercle, prolonged posteriorly as a short, indistinct carina. Prosternum unarmed, transversely concave, moderately brond, slightly expanded posteriorly; mesosternai process broad, slightly transverse, deeply emarginatc at apex; fifth sternite one-half longer than fourth, apex broadly emarginate. Pro coxae distinctly tumid posteriorly, anteriorly with small, robust tubercle; femora rather slender, feebly clavate, profemora robust, enlarged apically, finely rugose basally on upper nnd lower faces; metatibine strongly dilated before npex. Antennae slightly longer than body, ninth mcnt attaining elytral apex, the four proximal segments fimbriate beneath; .'leape short, reaching apical third of pronotum, ratber robust, strongly and gradually eJavate from base, the entire basal half coarsely rugose; third segment one-fourth longer tban senpe, distinctly sinuous, a fourth about as long as first, rest gradually shorter.

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.
