LAWRENCE S. DILLON <strong>AND</strong> ELIZABETH S. DILLON 135 APAMAUTA Thomson Apamauta Thomson, Pbysis, II, 1868, p. 58. Apamanta Lacordaire, Gen. Col., IX, 1872, p. 667, 674. Most closely related to H esycha but with lytra having sides more or less parallel ; antennae more slender, third and fourth segments not visibly enlarged; tibiae elongate and slender; femora slender, meso- and metafer.:lOl'a suddenly clavate beyond middle. Modcrato-sized, elongate-ovate, rather robust; reddish-brown to piceous. Head with front subqu.'l.drate, more or less parallel-sided, narrowed below eye; eye narrow, with lower lobe one-third tallcr than gena, elongate, oblong-ovate; nntennat tubercles prominent, well-separated, in male produced at apex into a short, robust tooth, which is directed vertically. Pronotwu transverse, apex only feebly narrower than at base, unarmed laterally; disk with five feeble tubercles. Scutellum trans verse. Elytra with sides only feebly attenuate apically; apices separately rounded; bMa: gibbosity small, disk simply punctate, not granulate; humeri prominent, angle with a small, obtuse tuberclE!, anterior margin strongly rounded. Presternum abruptly widened behind middle; mesosternal process deeply emnrginate at apex. Procoxac globose, in male armed anteriorly with a distinct uncus, which is but feebly curved ; femora robust, clavate, the meso- and metafemora slender at base, then abruptly clavate on apical half, profemora rugose basally in male; met.'l.tibi.'l.e not swollen in male, the tarsi in Hut sex somewhat dilated. Antcunac one-third or one-half longer than body in male, slightly longer than body in femalc; SCIlPC rather slender, subcylindrical, gradually clavate from base, grooved in male at pro}'-im.'l.l end ; third segment slender, moderately sinuous, about twice length of first; rest gradually shorter.

Apamauta lineolata Thomson, Physis, 1l, 1868, p. 59. Readily distinguisbed from all other species of the tribe by each elytron having three oblique, white lines, anterior one descending to suture, the other two behind middle ascending to suture.
136 THE TRIBE ONOIDERINI MALE. Elongate-ovate, subcylindriclll, clytra subconvex; head and pronotum dark reddish-brown or piceous, elytra paler; head, pronotwn, scutellum, and ex treme base of elytra grayish-yellow pubescent; remainder of elytru brown pubes cent, each elytron with three "narrow, short, oblique, white lines, the first a short distance behind humerus descending toward and nearly attaining suture at middle, the second just behind middle, shorter, less oblique, ascending toward but not at taining suture; third more apical, about as long as first, ascending toward suture and somewhat arcuate, a few indistinct, whitish maculae along lateral margin. Beneath dark reddish-brown, thinly clothed with grayish-yellow pubescence, this pubescence concentrated on abdomen to form a small, indistinct macula laterally on each seg ment. Legs dark or medium reddish-brown, thinly grayishyellow pubescent. An tennae with scape dark reddish-brown, remaining segments paler ; scape on basal twothirds and third segmcnt on basal onethird grayish-yellow pubescent, apices brown pubescent, fourth, sixth, eighth, and tenth on basal half whitish, remainder of these scgments and fifth, seventh, ninth and eleventh segments entirely brown pubescent. Head above minutely alutaceous, with a median impressed line from occiput to near middle of front; front subquadrate, narrowed somewhat abruptly ncar epi stoma, surface very finely, densely punctate, with scattered, coarse punctures; genae clongate, much wider on lower part, finely alutaceous, only very sparsely pubescent; eye with lower lobe much elongate, oblong, only feebly ovate, about one-third longer than gena ; antennal tubercles prominent, well separated, and produced at apex into a short, very robust tooth, directed upward. Pronotum transverse, apex subcqual t·o base in width, 'Sides feebly arcuate; a basal and an apical sulcus, basal one oblique laterally; entire surface with scattered coarse punctures, at sides near base with setigerous punctate granules; unarmed laterally. Scutellum transverse, sides straight, feebly oblique, apex subtruncate. Elytra with sides nearly parallel to apical third, thence rounded to apices which are separately rounded; each ely tron subgibbose at base and with a wide shallow depression following the line of the anterior margin of first white line; entire basal half of surface with moderately spaced, coarse, decp punctures, thence to apex punctures only very slightly smaller; humeri prominent, anterior margin broadly arcuate, angle with a feeble, obtuse tubcrcle. Prosternum abruptly widened behind middle; mesosternal process decply emarginate at tip; fifth sternite about one-fourth longer than fourth, at apex feebly fringed and subtruncate. Procoxae globose, with a well formed, robust uncus; pro femora robust, clavate, rugose on basal third on all four surfaces, other femora not as robust and more abruptly clavate; protarsi feebly dilated. Antennae about one-third to one-half longer than body; scape rather slender, reaching only to apical quarter of pronotum, gradually clavate, beneath at base with two or three deep grooves, upper surface with small punctures, becoming finer apically; third segment slender, moderately cun'ed, about twice length of scape, remaining seg ments gradually shorter; moderately fimbriate on first, second, third, fourth, and slightly so on fifth segments. FEMALE. More robust; antennal tubercles only very feebly produced at apex; procoxae very feebly, obtusely tubercled; fifth sternite nearly twice as long as fourth, at apex deeply, angularly emarginate and with a triangular impression, the base of which is broad and deep (forming a sulcus along apical edge) and apex
