This group, so far as known to nic, contains but a sinplc species, found in Louisiana, Eiicerrns varicorni's Leo., a small brown shin- ing insect, of the form of Trechus, but with the elytra truncate, and the outer joints of the antenna) white. I formerly placed it in Ilarpalini, but the anterior tibice are slender, and not at all spinous. It cannot bo i)laced with the Lcbiini, since the ligula is free at the apex for a short distance. The ])ubescence of the antenna extends upon the third joint, and even the second is not entirely free from it. The last joint of the palpi is oval and acuminate. The mcutum is not toothed, I have placed it in the present tribe for want of a more conve- nient position. It is, however, an osculant form which is ecpially out of place in any tribe here defined. The basal margin of the elytra is more strongly defined than in any of the other genera having truncate elytra. Tribe VII.—LEBIIIVI. The ligula in this tribe has the paraglossa) connate to the apex, and somewhat variable in form. The maxillary palpi are filiform, the labial sometimes dilated. The antenna) are filiform, with three basal glabrous joints, except in Trcchicus. The bead is sometimes constricted behind into a neck, but usually not; the anterior tibia) are not thickened at the tip, and rarely have any spines at the apex. The elytra are truncate at tip, and shorter than the abdomen; though in Tetragonoderus they are obliquely subsinuate, almost as in certain Pterostichini; the margin is not angulated at the hu- meri, and the basal margin is sometimes wanting. The anterior tarsi of the male are usually but slightly, rarely strongly dilated, with squamiform papilla) beneath. The ungues are frequently serrate. Two groups may be formed :— Labrnm short, mandibles exposed. Lebi;8. Lab
