Pronotum fu!vous-grtly, with sparse points of dark brown over most of surface, disk medially broadly tlnd at middle of each side of base indistinctly, brown-maculat.e. Scutellum dark brown pubescent, laterally distinctly margined with hoary. Elytra with a large, common, inverted triangular, brown area at base, i apex extending to ncar middle of suture, i sides running indistincUy below humeri; behind this an indistinct, oblique, whitish fascia which attains the suture but which is displaced laterally by fulvous-gray pubescence, this pubescence covers most of the sides and the Bpienl region, where it is mottled indistinctly with dark brown. Body beneath dark reddish-brown, irregularly covered with fulvous-gray pubc.:icence; abdominal sternites fuscous, apices of second to fourth sternites testa ceous, entirely fulvous-gray pubescent, mottled rather densely wit,h dark brown, the fulvous-gray more or less condensed laterally to form two poorly-defined vittae each side, one marginal, the other about half-way between margin and middle.
