136 THE TRIBE ONOIDERINI<br />

MALE. Elongate-ovate, subcylindriclll, clytra subconvex; head and pronotum<br />

dark reddish-brown or piceous, elytra paler; head, pronotwn, scutellum, and ex­<br />

treme base of elytra grayish-yellow pubescent; remainder of elytru brown pubes­<br />

cent, each elytron with three "narrow, short, oblique, white lines, the first a short<br />

distance behind humerus descending toward and nearly attaining suture at middle,<br />

the second just behind middle, shorter, less oblique, ascending toward but not at­<br />

taining suture; third more apical, about as long as first, ascending toward suture and<br />

somewhat arcuate, a few indistinct, whitish maculae along lateral margin. Beneath<br />

dark reddish-brown, thinly clothed with grayish-yellow pubescence, this pubescence<br />

concentrated on abdomen to form a small, indistinct macula laterally on each seg­<br />

ment. Legs dark or medium reddish-brown, thinly grayishyellow pubescent. An­<br />

tennae with scape dark reddish-brown, remaining segments paler ; scape on basal<br />

twothirds and third segmcnt on basal onethird grayish-yellow pubescent, apices<br />

brown pubescent, fourth, sixth, eighth, and tenth on basal half whitish, remainder<br />

of these scgments and fifth, seventh, ninth and eleventh segments entirely brown<br />

pubescent.<br />

Head above minutely alutaceous, with a median impressed line from occiput to<br />

near middle of front; front subquadrate, narrowed somewhat abruptly ncar epi­<br />

stoma, surface very finely, densely punctate, with scattered, coarse punctures; genae<br />

clongate, much wider on lower part, finely alutaceous, only very sparsely pubescent;<br />

eye with lower lobe much elongate, oblong, only feebly ovate, about one-third<br />

longer than gena ; antennal tubercles prominent, well separated, and produced at<br />

apex into a short, very robust tooth, directed upward. Pronotum transverse, apex<br />

subcqual t·o base in width, 'Sides feebly arcuate; a basal and an apical sulcus, basal<br />

one oblique laterally; entire surface with scattered coarse punctures, at sides near<br />

base with setigerous punctate granules; unarmed laterally. Scutellum transverse,<br />

sides straight, feebly oblique, apex subtruncate. Elytra with sides nearly parallel<br />

to apical third, thence rounded to apices which are separately rounded; each ely­<br />

tron subgibbose at base and with a wide shallow depression following the line of<br />

the anterior margin of first white line; entire basal half of surface with moderately<br />

spaced, coarse, decp punctures, thence to apex punctures only very slightly smaller;<br />

humeri prominent, anterior margin broadly arcuate, angle with a feeble, obtuse<br />

tubcrcle. Prosternum abruptly widened behind middle; mesosternal process decply<br />

emarginate at tip; fifth sternite about one-fourth longer than fourth, at apex feebly<br />

fringed and subtruncate. Procoxae globose, with a well formed, robust uncus; pro­<br />

femora robust, clavate, rugose on basal third on all four surfaces, other femora<br />

not as robust and more abruptly clavate; protarsi feebly dilated. Antennae about<br />

one-third to one-half longer than body; scape rather slender, reaching only to<br />

apical quarter of pronotum, gradually clavate, beneath at base with two or three<br />

deep grooves, upper surface with small punctures, becoming finer apically; third<br />

segment slender, moderately cun'ed, about twice length of scape, remaining seg­<br />

ments gradually shorter; moderately fimbriate on first, second, third, fourth, and<br />

slightly so on fifth segments.<br />

FEMALE. More robust; antennal tubercles only very feebly produced at apex;<br />

procoxae very feebly, obtusely tubercled; fifth sternite nearly twice as long as<br />

fourth, at apex deeply, angularly emarginate and with a triangular impression, the<br />

base of which is broad and deep (forming a sulcus along apical edge) and apex
