Jine on each side; elytra griseous, with a longitudinal row of quadrate 

 fuscous spotSj interrupted towards the apex with a distinct white one; 

 abdomen with the sides and base above black, the apex red; legs testa- 

 ceous ; posterior femora of a duller hue, with brownish spots, beneath 

 greenish-yellow ; knees black ; tibiae red, with the extreme apex fuscous.

 accompanied by two other paler ones, along the ridge of the elytra ; again' 

 in some, the posterior femora are immaculate.
