“General: Body 1.7 times as long as wide; dorsal surface rather shining, elytra less so than pronotum; dorsal surface without pubescense; most of ventral surface with short, sparse pubescence. Head: Front and clypeus creamy yellow, an inverted V from vertex to antennal insertions and labrum reddish; front with moderate sized, rather coarse punctures; clypeus with basal margin obsolete, lateral margins rather distinct, broad, somewhat broader apically than at base. Antennae in female over half length of body, in male about three-fourths length of body; basal two to five segments orange, remainder blackish. Pronotum: Deep orange to red, usually with two vague, yellowish spots at base; lateral margin narrowly to rather broadly yellowish, this narrowly interrupted by red at middle; apical margin narrowly yellowish. Punctation dual, smaller punctures minute, larger punctures small, not dense. Elytra: Background color creamy yellow to light orange; dark markings brown to black, rather sharply delimited; each elytron with three transverse, dark, undulate bands, all broadly confluent with suture, first centered at basal third, attaining neither base nor lateral margin, second centered behind middle, attaining lateral margin, third centered before apex, not attaining lateral margin. Each elytron with seven rows of punctures, usually with an incomplete row between fifth and sixth; fifth and sixth rows usually confused; punctures small, dense as usual, finer to apex; inner and outer rows distinct at apex and clearly meeting. Ventral surfaces: Ventral surface and legs orange to light reddish, legs brownish apically; with yellowish on prosternum, mesosternum, mesepimeron, middle of first abdominal segment at base, and sides of abdominal segments. Anterior margin of male prosternum feebly produced into a broad, arcuate lobe or in female not produced and evenly arcuate. Pygidium yellowish apically, with median line, sides, and basal half orange or reddish; with a feeble, median carina; coarsely punctate. Fifth abdominal segment in female with a large, oval, deep depression at center as usual or in male feebly depressed. Length: 4.0 to 4.4 mm” (White, 1968: 91-2).
“The species is most similar to cowaniae and can be distinguished from it by the elytral pattern. In cowaniae, the dark elytral markings are mutually confluent lateral to the elytral suture; in this species, they are not confluent (first and second bands) or meet only at the suture (second and third, sometimes first and second). The specific name refers to the three undulate bands of the elytra” (White, 1968).
