Prothorax short, constricted and abruptly narrowed in front; densely, finely punctate. Elytra broad, 
subtriangular ; punctate-striate, the interstices rather convex, finely punctate, 2 and 3 slightly swollen

Iwo specimens, both from the State of Vera Cruz. Near 4. nigronotatus *, but 
with the eyes more prominent, the head more hollowed between them, the prothorax 
shorter, the elytra each with a single rather large blackish patch near the suture at
