Palmerella, gen. nov. Areolet minute, punctiform, the recurrent nervure received at its apex ; the transverse median nervure received shortly behind the transverse basal ; transverse median nervure in hind wings broken near the bottom ; radial cellule elongate ; disco-cubital nervure unbroken. Metanotum with one transverse keel, and with a square area in the middle of the base, behind the keel ; the sides at the apex armed with long spines ; the spiracles ovate, of moderate size. Abdominal petiole rather stout, broad, curved, longer than the second segment. The third antennal joint not much longer than the fourth. Hind legs very long. Palpi long, the maxillary reaching to the middle coxae. Scu-tellum roundly, broadly conical ; the apex has a long, steep slope. Eyes lai'ge, parallel. Thorax fully three times longer than wide ; the head is wider than it ; its front is depressed and is keeled down the middle ; there is a complete metapleural keel. The parapsidal fur-rows extend from the base to the apex of the mesonotum. The type of this genus differs from the other Mesostenini (the group to which it belongs) in having the body and legs black : the scutellum is much more prominent than it is with Mesostenoideus or Buodias, and, more particularly, in being steeply declivous behind ; the hind legs are longer and more slender, and the abdomen shorter and narrower, its petiole stouter and of more equal width, as well as being longer com-pared with the second segment. Looked at from the sides the base of the metanotum is seen to be depressed, the post-scutellum appearing behind the depression as a small tubercle. The type of the genus has hardly the appearance of a
