The antennae extend back to about the hind margin of the seventh segment; on the dorsal surface of the head, between the antennae, there is a pair of strong setae, and on the front sur- face, midway between the dorsal setae and the labrum, there is a pair of similar setae; each lobe of the labrum bears a group of stout 46.
