Large punctures 45X diameter of eye facet, small punctures 3X diameter; interspaces smooth to finely alutaceous, shining. Most small punctures giving rise to elongate curved golden seta. Pronotal surface with large punctures equal to large ones on vertex, interspersed with numerous small punctures, ~0.330.5 large ones; interspaces smooth to alutaceous, 0.330.5 diameter apart. Scutellar surface with numerous shallowly impressed punctures, somewhat larger than smaller ones on pronotum; interspaces alutaceous to granular. Elytral surface with serial rows of alternating large and small deep punctures, rows of small punctures confusedly dispersed often with 2 rows of small punctures between rows of large punctures. Small punctures equal to smaller ones on pronotum, large punctures 2X diameter of smaller ones. Smaller punctures giving rise to erect long golden setae, large punctures giving rise to semi-erect long golden setae; interspaces narrow between punctures of a row and between different rows. Within a row, small punctures separated by 0.751 puncture diameter, and large punctures by 0.10.25 diameter.
