One specimen. Very like M. paludicola, but with entirely pale legs and antenna, 
and also a little less elongate in shape, the connexivum broader, the pronotum without 
trace of median ridge, the venter in great part testaceous, the elytra mottled with 
whitish. The pale legs, &c., separate it from M. americana, Uhler.
