The antennae are eight-jointed, viz., scape, pedicel, two ring joints, and four in the club. The second ring joint is very minute, and as it lies practically within the base of the club, its presence is demonstrable only in slowly dehydrated preparations. The number of the major sensoria on the club segments is probably a generic character. In the ♀ this appears to be 1.1.2.3, and in the ♂ 1.1.1.2. The following details of chaetotaxy would also seem to be of generic value : mesoscutum with four stout bristles (one posterolaterally and one in front) ; one on parapside before the tegula and another on the invading portion of the axilla ; scutellum four bristles ; metanotum 2.2 (very minute) ; propodeon two (minute) behind the spiracle.
