fulvous and with tin indistinct, narrow, fulvous vitta either side ; pronotum with a
narrow, fulvou!> vitta medially on apical twotbirds, one either side of middle slightly
oblique and coalesccnt tit middle of base, laterally either side over tubercle a broad
yellowishwhite vitta, which is 3. eontinuat.ion of the whitish patch on side of head.
Scutellum brown pubescent, only ·basal angles and lateral edges shortly whitish.
Elytra. with the vittae of pronotum just continued on ext-reme base, remainder of
surface with mnny, very narrow, irregularly placed, long lines of deep Iulvous and
outlined with a grayish pubescence, these on apicnl quarter more or less forming
forked lines, a very narrow, broken, whitish fascia with three or more dentations,
beginning laterally behind middle lind extending obliquely forward to beyond middle
of disk near suture, a broad band of the dark brown pubescence behind the whitish
vitta which lacks the fulvous lines of the rest of the surface. Beneath dark brown,
with vnriegated pubescence of brown and pale fulvous, the dark brown predominant
on sides of sterna nnd sternites and the stcrnites with a very small, rounded, fulvous
macula each side. Legs durk reddish-brown to fuscous, thinly pubescent with variegated
fulvous and brown; femora. at apical twothirds with a fulvous macula and
nt apex a fulvous fascia. Antennae with scape dark reddish-brown or piceous, re
maining segments reddishbrown ; scape variegated with brown and fulvous pubes
cence, a large irregular spot of brown at apex., remaining segments brown pubescent
very narrowly and feebly annulate at base with gray.
Head above finely alutaceous, with It median impressed line from occiput nearly
to epistoma; front nnrrowed slightly below eyes, finely alut.aceoos, with well spaced,
deep punctures interspcrsed; genae elongate, narrow, pubescent, minutely nlutaceous
; eyes with lower lobe small, narrowly ovate, subequal to genae; antennai
tubercles promincnt produced internally into short, very robust, obtuse processes
usull.l!y directed forward and inward. Pronotum transverse, base only slightly
wider than apex; sides feebly arcun.te; a basal and apical sulcus, basal one oblique
over latcral tubercles; disk just behind middle with an elongate, moderately elevated
tubercle, either side of middle n large, rounded tumid area; lateral tubcrcles
broad at base; obtusely produced, just anterior and slightly dorsal to these a. small
rounded, tumid area; base of center of disk and lateral tubercles with a few punctate
granules. Scutellum transverse; sides straight; apex subtruncate, moderately
notched medially. Elytra nearly parallel to behind middle thellce feebly attenuate
apically ; apices each rounded; disk coa.rsciy, dcnsely punctate on basal third, punctures
thence finer to apex; humeri prominent, anterior margin strongly oblique,
angle with a small tubercle. Prostcrnum much broader behind middle; mesosternnl
process allgulate and emarginate apically; fifth aternite about one-fourth longcr
th.'IR fourth, feebly emarginate apically. Procoxac globose, with a very hrond obtuse
tubercle internally; profemora clavate, rugose on all four sides on basal twothirds,
remaining femora gradually clavat.e; protnrsi slightly dilated. Antennac

nearly capitate, rcnching only to middle of pronotum, with ono or two deep grooves
internnlly and externally at base, remainder of surface finely densely punctate,
third and fourth segments somewhat thickened, and third nearly twice length of
scape and fccbly sinuate, fourth nearly twice length of fifth, remaining segments
subequal.

dueed; presternum wider behind middle and more abruptly so; fifth sternite about
