Hah. Ashantee. M y collection. Smaller than M.fiavltarsus, Jac, and M. tarsalls, Lefev., the legs differently coloured, the head more strongly punctured, and the elytra in the male wdth very strongly raised lateral costae. There is a single female specimen from the same locality before me, which has the terminal joints of the antennae darker as well as the tarsi, and the elytral costae much less strongly raised; but whether this is the female of the present species or of another I am unable to say.
