trorum, nonnumquam absente ; capite sat magno; oculis magnis, haud prominentibus ; pronoto modico, ad 
basin latissimo, minutissime punctato, interstitiis glabris, nitidis lateribus leviter marginatis et leviter

mark behind the middle, and the base very narrowly, piceous, the dark markings sometimes effaced. 
Head rather large; eyes large, not prominent; antenne long, rufescent. Uhoraw moderate, widest at the 
base, very minutely punctured, with the interstices smooth and shining ; sides slightly margined and

Hab. Nicaragua, Chontales (Janson). 
This species is distinguished by its pale yellow or testaceous colour, the elytra often 
with a transverse lunate mark behind the middle, and the base very narrowly, piceous. 
A well-marked example is shown on our Plate.
