Pronotum very strongly transverse, two and one-half times as wide as long; median lobe strongly produced, nearly concealing scutellum; disk finely, densely punctate, punctation usually concealed by scales. Each elytron with 3 nearly equally spaced, transversely undulate bands of white scales meeting or almost meeting dilations of orange or red sutural stripe. Elytra finely, densely punctate. Venter black densely covered with black and orange scales.

Larvae - Family diagnosis

Elongate, cylindrical to ovate and somewhat flattened; dorsally covered with usually evenly sclerotized tergal plates, sometimes extending onto ventral surfaces posteriorly; dorsal vestiture of bands or fascicles of long and short setae which may be spinulate, segmented and hastate hastisetae, smooth nudisetae, branched, clubbed, or slender, bearing sharply pointed imbricate scales, spicisetae; these sometimes, especially hastisetae, forming tufts in posterior region. Head hypognathous, subglobular, visible from above. Epicranial stem long; frontal arms straight or slightly angulate, forming Y-shape; median endocarina sometimes present. Frons sometimes bearing small spine on each side. Antennae 3-segmented; segment 2 very variable in length, usually with variable sensory appendage(s) at apex. Ocelli present, 3 to 6 on each side, or absent. Mandibles sometimes more strongly sclerotized in apical half, uni- to tridentate apically or sometimes truncate; mola absent; hyaline prostheca and basal penicillus sometimes present; pseudomola rarely present. Maxillae with lacinia bearing one or more stout, curved apical spines; galea simple, densely setose; palpi 3 to 4-segmented. Labium with ligula apically emarginate, palpi 2 to 3-segmented. Labrum with anterior margin emarginate; labroepipharyngeal marginal region with series of setae becoming progressively broader from sides toward middle. Legs well developed, 5-segmented, tarsunguli bisetose. Abdomen 10-segmented, sometimes bearing retrorse tubercles in transverse row posterior to anterior transverse ridge (antecostal suture) on tergites 4 or 6 to 9 or 10; tergite 9 sometimes with urogomphi, segment 10 terminal or ventral, sclerotized or not. Spiracles usually annular, sometimes annular uniforous, often inconspicuous, since unpigmented.
