HYMENOPTERA. 129 In some the first segment of the thorax forms either a transversal or longitudinal square, and the abdomen is attached to the thorax by a very short pedicle; the inner side of the posterior tibire is usually furnished with a brush. The superior wings have two or three complete or closed cubital cells, and another imperfect and terminal. They now form several subgene1·a . PEPsxs, Fab. To which I assign the following characters: labrum apparent; antennre, at least of the males, almost straight and composed of compact or crowded joints; maxillary palpi hardly longer than the labial, projecting, and formed of but slightly unequal joints; three complete cubital cells, and the first recurrent nervure inserted near the an.terior extremity of the second. The tibire and first joint of the posterior tarsi are compressed in the males. All the species known are foreign to Europe, and most abundant in South America and the Antilles; they are large, and have coloured wings( 1 ). CEROPALEs, Lat. Fab. The labrum and antennre of the Pepses; but the maxillary palpi are much longer than the labial, pendent, and with very unequal joints(2). PoMPILus, Fab. The Pompili, in this latter respect, resemble the Ceropales, but the antennre of both sexes are curled and composed of loose or but slightly compact joints; the labrum is concealed or but little exposed. According to Fabricius and the more recent systems, we must restrict this subgenus to those species in which there are three complete cubital cells, neither of them petiolate, the mandibles are unidentated on the inner side, and the thorax is slightly or mode· rately elongated in comparison with its width. These Insects lay up provisions for their larvre, consisting of Araneides, which they first put to death with their sting, and then transport to the holes destined for the domicil of their young.
