uninterrupted, of equal width, and split or divided near the base, and in having a 
similar narrow stripe accompanying the lateral margin for its entire length. The 
usual mark at the shoulder is broad, and extends nearly to the middle of the elytra, its

a large V-shaped or angulated spot is placed close to the suture below the middle, and 
the rest of the disc is occupied by nine or ten irregular spots; the lateral and sutural 
stripes are joined at the apex. A Guatemalan specimen received from the Stuttgart 
Museum is much larger, and has many more spots posteriorly.
