 the rounded hind angles, the median channel shallow. 

 Elytra long, subparallel, much wider than the prothorax, 

 somewhat produced at the apex, alutaceous, feebly tricostate, 

 the interspaces with about five rows of rather fine punctures, 

 the inferior margin finely crenulate. Ventral segments 

 rather closely, finely punctate. Tarsal claws long, with a 

 sharp tooth just beyond the middle.

 with a deep, transverse, arcuate excavation in the centre

 median lobe of sedeagus 3tout ; curved downward and acumi- 

 nate at tip.

Forty-seven specimens, including numerous males, two of 

 which have been dissected. Recognizable by its elongate 

 form and dull metallic upper surface, the flavescent femora, 

 the laterally flattened, scabrous prothorax, and the closely 

 punctured long, tricostate elytra, the fifth ventral segment 

 of $ with a deep transverse excavation. Near M. alluaudi, 

 Pic (=zmonticola, Gahan), opaque above, the prothorax more 

 flattened at the sides and less rugose, the elytra mote finely 

 punctured. M. taborensis, Pic (1903), seems to be an allied 

 form with the abdomen testaceous.

? . Elongate, subparallel, rather convex ; the upper sur- 

 face opaque, green, tinged with violaceous on the head and 

 prothorax, the lower surface shining, metallic green, the 

 ventral surface suffused with violaceous ; the antennae (except 

 the reddish portions of joints 1—4), tibise and tarsi, and the 

 apices of the femora, black, the rest of the femora, the 

 trochanters, and the anterior coxa? flavous, the wings bluish ; 

 sparsely pubescent, the apex of the abdomen with long 

 blackish hairs. Head narrow, elongated anteriorly, aluta- 

 ceous, and densely punctulate and reticulate, the anterior 

 portion finely punctured, the supra-orbital ridges prominent, 

 the eyes depressed ; antennae short. Prothorax nearly as 

 long as broad, conical, rapidly narrowed from the base, 

 feebly convex ; densely punctulate and reticulate, the median 

 channel shallow, the lateral carina sinuous, prominent, 

 reaching the rounded hind angles. Elytra long, subparallel, 

 much wider than the prothorax ; rugulose, tricostate, the
