Description.

-As in Key 1. A distinctive species in its robust build, highly sculptured, rugose integument and broad tegmina and wings. Antennae rather narrow basally, in male slightly longer and in female shorter than combined length of head and pronotum. Frontal ridge rather broad with wavy margins; fastigial constriction weak. Fastigium parabolic, rather short, medial carinula distinct, arcuate sulcus behind middle (Fig. 88). Pronotal carinae thick, lateral irregularly wavy in prozona, obsolete in metazona; metazona slightly shorter than prozona. Tegmina extend beyond hind knee, broad, not tapering apically. Venation and reticulation very irregular. Coloration variable, ground pigment somewhat speckled in shades of brown and charcoal grey; hind femur and tibia brown, hind wings yellow basally, infumate apically. Table 4 gives morphometric data for semicarinata .
