slender antennae with antennomeres of similar shape
, bi- or tricolored, antennomereantennomere:

1 pale olivine, antennomeres 2-11 olive ocher. Maxillary palpi black or amber brown, labrumlabrum:
the "upper lip" of beetles, a movable sclerite joined under clypeus
black. Pronotumpronotum:
the notum of the prothorax with highly sclerotized pronotal disc

small, usually triangular shield between the bases of elytra
black or amber brown. Elytra green, discdisc:
the middle, more uniform area of a structure (usually elytra or pronotum) which is visible dorsally
black or chestnut, maculatemaculate:
(here) marked by maculae or patches of a different shape and size, usually clearly separated from each other
with three yellow or rufous maculae, one in the basalbasal:
of or pertaining to the base, as in the first, or basal segment of an appendage; opposite of apical
part of elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
, one in the middle and one behind the middle of elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
. Elytral epipleura completely green. Elytral surface with four distinct sinuatesinuate:
curved in some way
sulci, strongest behind the humeral callushumeral callus:
<em>(pl. calli)</em> more or less marked tubercle or knob on the anterobasal angle of elytron
and extending beyond the middle, humeral plicae distinct. Sutural anglesutural angle:

of elytra round, punctation scattered, coarse. Abdomen pale olivine or green. Tarsi and tibiae black or chestnut. Femora pale olivine. Aedeagusaedeagus:
