Machaepotypus Uhler, Proc. U. S. Nat. Mus. XIX : 284 (1896). 



Characters : Closely related to the preceding genus but having the suprahumerals reduced to 

 mere folds or ridges or at most only auriculate rather than cornute and in having the laminate posterior 

 process only slightly flattened. Head subquadrate, wider than high; base arcuate and weakly sinuate ; 

 eyes large and ovate; ocelli large, prominent, equidistant froni each otherand from the eyes and situated 

 well above a hne drawn through centers of eyes; inferior margins of genae sloping and sinuate; clypeus 

 extending for half its length below inferior margins of genas, tip rounded and pilose. Pronotum convex 

 with suprahumerals very small, auriculate or ridged; metopidium almost vertical, convex, much broader 

 than high; median carina strongly percurrent; humeral angles heavy, blunt and triangular, extending 

 farther outward than the suprahumerals; suprahumeral horns consisting merely of ridges or folds or 

 short auricular projections; posterior process heavy, shghtly laminate, tectiform, and reaching a little 

 beyond the internal angles of the tegmina; scutellum narrowly exposed on each side. Tegmina opaque 

 or translucent; base coriaceous and punctate ; five apical and two discoidal cells; apical limbus well 

 developed. Legs simple; tibije strongly pilose; hind tarsi longest. 



Type sellatus Uhler.
