). In this species intervals 7-9 and the apex of the sutural stria are rufobrunneous to flavous, whereas the basal portions of intervals 2-5 are rufopiceous. The dorsal surface of the head and the pronotum are rufous with a flavous cast. The pronotum is moderately transverse, MPW/PL = 1.26, and basally constricted, MPW/BPW = 1.58. The dorsal surface of the head bears well-developed isodiametric sculpticells arranged in transverse rows. The setal formula is 2 1 2 0; the other two bicolored species-
