Seniculus is distinctly fulvous pubescent j the elytra are distinctly
maculate on apical third with ocbraceous j and the tarsal
claw segment is paler than others, dark only at extreme tip.
FEMALE. Elongate-ovate, rather robust, convex above; dark reddish-brown,
covered with grayish tLud pale fulvous pubescence. Head and pronotwn mottled
with brown pubescence. Elyt-ra with the pale fulvous pubescence more or less condensed
here and there, especially along suture and apically, to form a number of in­
distinct maculae. Body beneath, legs, and antCllOae reddish-brown, cntirely covered
Ivith pale grayish-fulvous pubescence, finely mottled with brown; tarst:\l claw seg­
ment paler than others, d:trk only at. extreme tip; :tntennal segments from third
tinged with brown at apices.
Head minutciy alutaceous, with a median impre&ed line from occiput to near
cJypeus; front concave between antennal tubercles, elongate, slightly n:trrower
above, minutely, densely punetate, without larger puncturcs; genae transverse,
minuteJy alutaceous; eye with lower lobe broadly oblong, large, nearly three hmes
the height of gena, a little wider above than below; antennal tubercles r:tthcr robust,
slightly prominent, widely separated, at apex with a very short, acute tooth. Pro­
notum transverse, about one-half again as wide as long, sides slightly narrower at
apeX thnn at base, unarmed, exp!1nded from behind middle, theli llarrowed apically;
apical transverse sulcus obsolete, basal one distinct, straight, connecting with the
short lateral oblique ones; disk entircly tumid, almost altogether smooth, with !1
tubercle at middle and one each side feebly elevated, obsolete. Scutellum slightly
transverse; sides broodly rounded ; aJlC.'" more strongly so, slightly impressed at
middle. Elytra indistinctly narrowed to apices, which are separately rounded ; disk
at base coarsely, not densely punctate, behind middle punctures finer, from apical
quarter obsolete; humeri feebly prominent, anterior margin curved, :tugle without a
tubercle, but here begins a long, smooth carina whlch extends posteriorly to slightly
beyond middle. Prosternum suddenly widened before middle, then gr!1dually ex­
p!1nded t.o basco Procoxae with a low obtuse tubercle anteriorly; femora robust,
clavate, metafemora more slender, profemom not rugose. Fifth eternite one-half
longer than fourth, ape;..: feebly retuse. Antennae slightly longer th:tn body, sparsely
fimbriate beneath to apex; $Cape slender, feebly clavate from b:t.se, not rugose;
t,bird segment one-fourth longer than first, slightly sinuous; fourth about as long as
first, rest gradually shorter; eleventh a little longer than tenth, tapering.
