disc, almost impnnctate, the base feebly bisinuate. Scutellum elongate-triangular, hollowed in front. 

 Elytra wider than the prothorax, oblong-subcordate, finely punctate-striate, the interstices each with 

 an irregular row of excessively minute punctures. Pygidium rather convex, coarsely punctured. 

 Beneath very sparsely and finely, the abdomen somewhat coarsely, punctate ; ventral excavation long 

 and shallow. Anterior and intermediate coxae with a small tuft of short hairs. Femora sparsely 

 pilose beneath, the anterior pair almost bare. Posterior tibiae (fig. 18 6) with a matted tuft of very 

 long curled fulvous hairs at about the middle and a few finer and shorter hairs between it and the 

 apex. 

 Length I3|, breadth 4| millim. 



Hob. Nicaragua, Chontales (Janson). 







One male, somewhat discoloured. Narrower and more convex than M. dimidiati- 

 pennis, the prothorax relatively longer, the posterior tibise with a matted tuft of very 

 long curled hairs in the male, the fifth ventral segment not foveate in this sex, the 



markings of the upper surface different.

Oblong-oval, rather broad, opaque above ; black, the prothorax with a triangular or v-shaped mark at the 

 base and an oblique stripe on each side of the disc (sometimes connected), and the elytra with a

 towards the apex, rufous or fulvous, the mesothoracic side-pieces sometimes rutescent. Eostrum ( 3 ) 

 curved, stout, compressed, shorter than the prothorax, very sparsely, finely punctate above, sulcate, laterally 

 crenulate, and angulate near the tip beneath, ( £ ) almost smooth above and beneath, and slightly 

 longer, the frontal fovea small. Prothorax as long as broad, parallel at the sides behind, finely punctured 







laterally and at the apex, flattened and almost smooth on the disc. Scutellum elongate-triangular. Elytra 

 much wider than the prothorax, oblong-subcordate, finely punctate-striate. Pygidium coarsely punctate,

Hab. Mexico, Toxpam in Vera Cruz (Salle: $); Guatemala, San Isidro and 

 Mirandilla, Pacific slope {Champion: 8 2 ). 





Three specimens, varying in the extent of the rufous or fulvous markings, though the 

 general pattern is similar. Very like M. sig niv entris (Kirsch), but with a differently 

 formed rostrum, and the posterior tibiae strongly ciliate, in the male ; the transverse 





oblique fascia below the base of the elytra uninterrupted, the prothorax relatively 



wider, the prosternum convex between the coxse in the female, the metasternum 



immaculate.
