Wv reh'r to trapezoideus the present; material, as well as a fe- 
male' from “Central America” collected by the Rev. T. Heyde, 
and a pair from Guatemala City, Guatemala. This is a species 
re'lated to B. discoidalis Serville, but averaging larger, more at- 
tenuate, showing a usually more distinct tinge of tawny, with 
tegmina more elongate and having their apices more shari)ly 
rounded, particularly in the male sex. The dark marking of the 
humeral trunk often spreads over the proximal iiortion of the 
discoidal field, but in recessive examples that suffusion is de- 
cid('dly reduced and sei)arated from the marking of the humeral 
trunk by a ])ale interval.

sci'iption, eitlu'r that his tra pezoidea was based on the mah',
