Agrainmodes Uhler n. gen. 
“Form conico-ovoid, similar to a bro id Agramma, but widely different in venation, 
and having the head formed nearly as in Piesma. Head much narrower than the pro- 
notum and curving down in continuity therewith, the base wide, with tlie clypeus abruptly 
narrower, protracted forwards in two slender tapering lobes in advance of the stouter 
tylus; eyes large, round, seated clo.3e against the pronotum. Antennae short, clavate at 
tip, the basal joint stout, contracted at tip the second very short, moniliform, the 
third longest and most slender, the fourth shorter, contracted on the basal portion. 
Postrum tapering, reaching behind the anterior coxae. Pronotum gently curved, some¬ 
what flattened near the anterior angles and depressed behind them, the anterior submar- 
gia inflated into a crescentiform low hood which does not extend to the lateral angles; 
lateral margin sharp cut, a little diagonal; surface coirsely granulated. Scutellum 
minute, tumid. Legs short and thick. Hemelytra broad suboval, granulated, coriaceous 
throughout, with the veins very coarse and prominent; clavus formed of one short tri¬ 
angular areole, bounded exteriorly by a long and moderately narrow areole which is 
oblique at tip, and from this the inner vein runs back to near the tip and forms an arrest 
for the two discoidal veins which bound wide triangular areas, and curve inward as they 
approach this inner vein; the costal area wide, depressed, continued to end of wing-cover, 
crossed by a few irregular veins, the inner veins are continued across the area which 
forms a substitute for the membrane.”
