A row of small but sharp spines runs on each side the suture, from the middle almost to the scutellum; and along the sides runs another row from the anterior corners almost to the extremities. Six others are placed on each side the scutellum, running towards the middle in regular order; and on the remaining parts of the wing cases are placed a great number of small pustules, that are to be discerned only by the help of a microscope.
