Head, when viewed from above, rather large, wide and long. Eye relatively small. Width of vertex between eyes considerably exceeding breadth of one eye when measured from above. Vertical pits extremely shallow, to be regarded as nothing more than area bordered by two low Figs. 7 — 12: Bryodema divum sp. n., 7 = Head and pronotum from above, 8 = tegmen, 9 = hind wing, 10 = head and pronotum laterally, ll = abdominal end of female, laterally, 12 = posterior femur riblets bifurcating from facial pair of ribs decurrent between antennae and extending toward eyes. Scape short and wide from above, considerably shorter than section of facial rib between antennae. Vertex smooth, spotted, velutinous. In a lateral view, head thickset. Facial rib decurrent evenly and uninterruptedly to upper labrum. Eye relatively small; facial furrow arising on its lower portion slightly sinuous and shallow. Antennae originating aligned with median section of eyes. Pronotum wide and short. Anterior margin, when viewed from above, slightly sinuous, median ridge low, hardly detectable and apperceptible only by refracting light. Median ridge interrupted, or touched by a slight transversal furrow; posterior margin right-angled, caudal apex visibly rounded. In a lateral view, pronotum slightly scabrous, shiny, greyish brown. Anterior margin a laterally decumbent lateral lobe, slightly sinuous, anteroinferior corner strongly obtuse.
