Carinae between eyes light brown. Clypeus yellow or light brown, ecarinate. Vertex ( Fig. 27 ) brown or piceous, wider at anterior margin than long in middle line about 15:1, posterior corner with macula, bright yellow; carinate sublaterally, without central carina; occipital margin carinate and piceous. Pronotum brown or piceous, narrow, wider at widest part than long in middle line about 6:1, punctated beside central carina; anterior margin carinate. Mesonotum piceous. Mesopleura brown or dark brown. Tegmina ( Fig. 29 ) with costal marginal fascia brown or piceous, with a yellow spot near middle, posterior corner of the yellowish spot with one rather small white spot; apical margin with or without fascia, inner margin with a narrow brown fascia; disc without transverse fasciae; common stem of R1 and R2 longer than basal cell. Wings ( Fig. 30 ) with costal margin and apical margin without fasciae, inner margin with a narrow, light brown fascia. Figs. 14-26.
