DESCRIPTION. — Shiny black, elytra with slight or intense blue sheen; elytra at apex and last ventrites with dark pubescence; prosternum with sparse white hairs, mesosternal process with dense white hairs; prothorax with a white stripe of dense scales on either side, similar white scales forming a patch on outer side of fore coxa.

Head anteriorly shiny, sparsely punctulate, slightly alutaceous behind. Frons separated by 3 x the width of scape. Rostrum 0.74-0.77 x the length of prothorax, straight, depressed; postrostrum moderately punctate on either side, with a sulcus against scrobes; prerostrum a little wider than long, indistinctly punctate. Scape extending to about anterior third of eyes, weakly to distinctly compressed; funicle with segment 2 shorter than 1, shorter than 3 + 4; club as long as preceding six segments combined.

Prothorax a fraction longer than wide, sparsely, finely punctate. Scutellum smooth, glabrous.

Elytra 1.43 x wider than prothorax, 1.29-1.36 x longer than their combined width, broadened towards middle, then rounded off to a broad apex; in lateral view deep, almost humped. Striae complete, deeply sulcate from before middle; stria 10 with seven coarse puncta at base, followed by a fine engraved line. Interstriae distinctly punctate, with one row of puncta. Mesepisternum smooth; mesepimeron with few shallow puncta; metepisternum with a row of puncta, these nearly as coarse as those on sides of metasternum.

All femora with a strong tooth of similar size. Last three ventrites punctulate; ventrite 5 broadly smooth on midline.
