The species of this subgenus are only found in America(2). Sometimes the maxillary palpi have but a single and very small joint which in some even becomes invisible. The paraglossre are very short, and the mandibles dentated. EPIOHARis, Kliig.-Centris, Fab. Where the last joints of the labial palpi are in the same direction as the preceding ones, are rather indistinct and form the point of those organs which resemble very elongated setre. The second and third cubital cells receive, each, a recurrent nervure(3). AoANTHoPus, Kli.ig.-Xy!?copa, Fab • Where the two last joints of the labial pal pi form a small, oblique and lateral stem; the third cubital cell receives the two recurrent nervures. The internal extremity of the two poste1•ior tibire presents two strong dentated spines( 4). The last of the Apiarire form communities composed of males and femalea, and a considerable number of neuters or labourers. In the internal face of the posterior tibire-/a palette-of these latter individuals is a smooth depression-/a corbeille-in which they place the pellet of pollen collected with the silken down or brush attached to the inner side of the first joint of the tarsi-/a piece cm·ee-of the aame leg. The maxillary palpi are very small and formed of a single joint. The antennre are geniculate. (1) Insecta brought from Brazil by M, de Saint-Hilaire. My genus Melitome, Fam. Nat. du Regn.
