The species of this genus have been for the most part described under

M. perforata n. sp. 



Black shining. Female. Rostrum cylindrical, arcuate, moderately 

 punctured, median line at base smoother. Antennae median, piceous, 

 scape attaining the eyes. Head broadly conical, moderately punctured, 

 eyes flat. Thorax longer than wide, sides in front gradually arcuate, 

 posteriorly nearly parallel, not sinuate, base strongly bisinuate, disc 

 moderately coarse and shining, coarsely, densely and deeply cribrato- 

 punctate. Scutellum small, smooth. Elytra gradually wider behind, at 

 basal margin slightly impressed, surface with stria? of large deep quadrate 

 punctures separated by extremely narrow spaces, intervals narrow, uni- 

 seriately punctate. Pygidium coarsely and deeply punctate. Body 

 beneath black, coarsely and densely punctured, abdomen more sparsely 

 punctured. Legs black, femora mutic, the anterior femur impressed 

 near the base. Length .20 inch ; 5 mm. 



Has somewhat the aspect of a Cossonus. Tarsal claws simple. 



Occurs in Georgia. 



M. cuneiformis n. sp. 



Elongate, cuneiform, surface blue, shining. Rostrum moderately 

 arcuate, sparsely punctured, more densely near the base. Head broadly 

 conical, sparsely punctured, slightly impressed between the eyes. Thorax 

 longer than wide at bas->, anteriorly broadly but feebly constricted, sides 

 straight divergent, hind angles moderately prominent and (viewed from 

 above) truncate at tip, base deeply bisinuate, surface moderately convex, 

 deeply and densely punctured. Elytra scarcely wider at base than the 

 thorax, sides gradually divergent, at apical third arcuately narrowing, 

 surface moderately convex, base slightly impressed, and with rows of 

 moderate punctures in obsolete stria?, intervals flat, biseriately punctu- 

 late. Pygidium black, shining, coarsely punctured. Body beneath blue^ 

 shining, moderately coarsely and densely punctured. Legs sparsely
