fascia and a triangular patch on the disc before the middle. Rostrum curved, 

 rather slender, shorter than the prothorax, thickened at the base, sparsely very 

 finely punctate; the frontal fovea small. Prothorax elongate, subconical, with 

 a few coarse deep punctures along the middle of the disc at the base, and a row 

 of punctures along the basal margin ; the apical constriction also punctate, the 

 rest of the dorsal siu-face almost smooth. Scutellum elongate, smooth. Elytra 

 long, narrowed posteriorly, rather coarsely punctate-striate ; the interstices 

 with widely scattered excessively minute punctures, 1-5 more or less convex, 

 the others flat. Pygidium coarsely, densely punctate. Beneath coarsely punc- 

 tate, except along a broad space down the middle of the metasterniun and tlie 

 ventral segments 1-4, which is much smoother; ventral depression broad, 

 reaching the first suture ; the fiftli segment transversely depressed at the apex 

 and with the coarse punctvires along the middle each bearing an erect hair. 

 Tibia' witlunit tooth at the inner apical angle, the posterior pair densely ciliate 

 with long fulvoiis hairs from near the base to the apex...

One male, found in September. Near M. qvaclrUmeatvs, Champ., 

 from Mexico and Griiatemala, but with very different elytral markings; 

 the fulvous hairs on the posterior tibiae ( (^ ) extending along the inner 

 margin to the tip, and not clustered into a median tuft. The rostrum 

 is narrowly grooved beneath, as in the females of various allied forms. 

 M. connexus has similarly formed hind tibiae in the male, but it is not 

 very nearly allied to the present species.

 pronotiun sometimes fuscous and with the lateral angles, basal margin, and 

 two minute spots in front, ochreous ; the tip of the scutellum, two transverse

 triangular patch at its base, whitish, and an oblong or oblique spot near the 

 inner apical angle of the corium, and the tip of the cuneus ochreous ; the second 

 joint of the antennae ochreous or brown, the ft)urth with a broad white annulus 

 near the base ; the base of the femora, the tibia;, and the first two joints of the
