middle wit.h a distinct, irregular, but uninterrupted, white fascia which is strongly
oblique in the type, less strongly so in the para type from Pannmn, apical fourth of
disk more distinctly mot.tled with brown and irregularly maculate with white.
Body beneath dark reddil\h·brown, medially hoary pubescent, laterally pale fulvous;
abdomen at middle coycrad with boary pubescence, in type mottled with brown and
each sternite apically denuded, in the paratype almost uniformly grayish ; laternlly
vittate wit-h fulvous and finely mottled, the vitta very indistinct on first slernite.
Legs reddish-brown regularly clothed with coarse, hoary and fulvous pubescence,
the mesotibiae indistinctly (lnuulate at middle with hoary pubescence; tarsal claw
segments fuscous on apical two-fifths, base deep rosy. Antennae luscolLS, vnrie­
gated with dark brown and hoary pubescence; basal half of third and basal two*
fifths ol lollowing segments pale rosaceous, covered with fine, hoary pubescence.
Head minutely, densely punctate, with a median impressed line from occiput
almost to epistorna; front nearly flat between antennal tubercles, rather finely
and dcnsely punctate, tI submarginal linear impression from below eye to episwmn;
gena elongate, vertical, rather denseJy, rugosely punctate; eye with lower lobe
oblong, its height one-third less than that of gena ; antennal tubercles well Jrepa*
rated, moderately elevated, produced at apex into a distinct, acute tooth. Pronotum
transverse, sides straight, untlrmed, gradually narrowed to apex; apical and basal
tmnsverse sulcus distinct, the latter merging with the lateral ob lique ones; d.il!k
finely sp.arsely pUDcl.:lte across base, the median line somewhat cleva ted, narrow,
each side strongly tumid, tumescences not traversed by an oblique impre!sion.
Scutellum transverse; sides strongly oblique, straight; apex broadly rounded, im*
pressed at middle. Elytm with sides straight, slightly oblique; apices separately
rounded; disk at base feebly gibbosc either side, sparsely and moderately finely
punct.1te, posterior half finely and a little more closely punctate; hlUlleri somewhat
projecting, anterior margin straight, strongly oblique, angle with a large, sruning
tubercle, from wruch extends n. short, curved, feeble carina ; sides below a little
more densely and coarsely punctate than disk. Prosternum with a transverse
proc at middle between coxae. Procoxae tumid behind, anteriorly with a broad,
but feebly elevated, obtuse tubercle; femora clavate, profemora with several trans·
verse rugosities beneath at base; mel.:ltibiae apically greatly widened. Fifth Ilter*
nite one-half. again as long as fourth; apex broadly rounded. Antennae about
one*fourlh longer than body, finely and sparingly fimbriate beneath to apcx of nfth
segment; scapc slender, slightly capitate on apicn1 half, basally above coarsely
punctate; third segment visibly longer than first, biflexuose; rest gradually shorter;
eleventh tufted at apex.
