MARSHALL ON COLEOPTERA [Jan. 19, coarsely punctured, with three prominent narrow smooth carina?; lateral sulci deep, the upper pair uniting at base, longer and much broader than the lower pair; scx-obes deep, lateral and oblique, inferior basal furrow absent. Antennas with scape just reaching eye; the two basal joints of funicle very short, subequal. Prothorax compai'atively small, somewhat transverse, apex rather narrower than base, sides very little rounded, broadest rather- before middle, dorsal anterior margin truncate, ocular lobes feeble. Upper surface convex, fairly closely set with low rounded granules, leaving a shallow centx-al furrow containing a short but strong carina; granules shiny, beax-ing loxxg ex-ect black seta? antex-iox-ly, but with short depressed seta? behind, tlxe interstices with dense brown scaling. Elytra ovate, shoulders rormdedly prominent, sides somewhat rounded, bx-oadest about middle, apical processes absent in J . Upper surface convex, with shallow sxrlci containing rows of ill-defined punctures often sepax-ated by minute granules; all the intervals with x-egular rows of closely-set gi-anules, but 1, 3, 5, and 7 are more raised than the others, the granules also on them .are larger and bear long erect black seta?, whereas the gx-anules on the alternate intervals have much shorter subdepressed seta?; the apices of granules bare, the intersrmces with dense brown scaling. Legs coax-sely punctured and with fairly dense depx-essed pale seta?; posterior tax-si short and broad, the joints of about the same width, 2nd and 3rd subequal in length, 1st rather longer.
