outwardly, joint 2 moniliform, shorter than 1, 3 as stout as 2, and about equal to it in length, 3-10

has the elytra abruptly sinuate-truncate at the apex, with the sutural angles slightly 
produced. The male has a deep foveate depression at the apex of the last ventral 
segment. The arrangement of the elytral pubescence is constant, though the testaceous 
markings are sometimes indistinct.
