18 Psyche [February 
of Melanorhopala may be stated as follows: Form elongate, de- 
pressed, the hemielytra flat or showing only the slightest convexity. 
Antenne usually rather long and slender, the third segment cylin- 
drical, usually somewhat curved and enlarged toward the apex in 
varying degrees. Pronotum tricarinate; hood small and not 
produced anteriorly; paranota narrow, uniseriate, reflexed ver- 
tically or against the pronotal surface. Hemielytra in the long- 
winged form widely overlapping and broadly rounded at apex, in 
the short-winged form very slightly overlapping, acute and dis- 
tinetly divaricate at apex; main veins distinctly costate; costal 
area usually uniseriate, sometimes irregularly biseriate; subcostal 
area biseriate. 
The following table will assist in separating the species: 
1. Third antennal segment slender, not thicker than the fourth 
except sometimes at extreme apex; size larger.......... 2 
Third antennal segment rather thick, cylindrical, slightly 
clavate toward apex which is one third thicker than the 
fourth segment; form very broad; length, 3.5 mm
