Moderately elongate, narrow, subcylindrical, opaque, piceous, the elytra and legs fusco-castaneous, the 



punctures with a griseous incrustation. Head closely punctate ; rostrum stout,, curved, a little shorter 

 than the prothorax, not constricted at the base, unimpressed above, coarsely, confluently punctate to the 

 tip, sharply carinate between the rounded pterygia. Prothorax about as broad as long, obliquely narrowed 

 anteriorly and posteriorly, feebly constricted in front, and sharply margined at the base ; closely, 

 confluently punctate, except along the abbreviated slightly raised median line. Scutellum small, 

 flattened. Elytra moderately long, wider than the prothorax, convex, subparallel in their basal half ; 

 finely punctate-striate, the interstices broad, flat, each with a row of from 5-9 widely scattered, rather 

 large, rounded, griseo-incrustate foveas. Legs very slender, the tibiae fringed with a few short

and appear to be raised at first sight, but less so than in M. leprosus (Boh.).

Nicaraguan and Costa Rican specimens of this species have the scattered, rounded. 







hitish, asymmetrically arranged spots on the elytra a little larger and not quite so 

 numerous as in most of the South- American examples I have seen. The rostrum is 

 arcuate, constricted at the base r and closely punctate to the tip, the apical portion 

 being much smoother in the female. The elytra are obsoletely striate, the striae 

 pressed with scattered fine punctures. The tibia? are feebly ciliate in the male. The

length varies from 94-18, and the breadth from 3-6 millimetres
