anterior thighs are armed, and the anterior tibiee moderately dilated. Humeral angles 
of the pronotum strongly and prominently produced. 
The genus contains but two species, one common to the Neotropical Region, the 
other apparently confined to the Antilles.

Stal? considered this species a synonym of the Pentatoma phymatophora, Pal. 
Beauv. I am indebted to the kindness of Dr. Signoret for being able to examine 
the type of the last-named species, which seems quite distinct and easily recognized 
from MM. grandis by the structure and shape of the pronotal spines. These in 
M. phymatophora are not produced forwards, and are acutely pointed, being notched 
only on the posterior margin, some distance from the tip; the base of the scutellum is 
more sparsely punctured ; and the corium is much less confluently punctured. In the 
absence of intermediate forms I have therefore considered it distinct. Palissot de 
Beauvoir described his species as from St. Domingo. Owing to the apparent confusion 
of the two forms, I have abstained from quoting the habitats given by Stal and Berg, and 
have for the same reason discarded those of Walker in his Catalogue of Heteroptera.

In structure this genus differs principally from the preceding genera, which have a 
more or less triangular scutellum (save in Coryzorhaphis), by having the anterior femora 
unarmed; the anterior tibiz are not dilated ; and the abdomen is armed with a spine at 
the base. It comprises a considerable number of species, which are, with one exception, 
common to the Nearctic and Neotropical Regions, including the Antillean Subregion. 
Stal has founded several subgenera, which are here treated as sections.

pronotum unarmed. Apateticus, Dall.
