Genitalia; b, S7; c, S8. preapical sublateral smooth convex areas resembling bosses or tubercles of some other species but so low as to be scarcely recognizable in lateral view (Fig. 20a); S5 with similar but scarcely elevated areas. Genitalia and hidden sterna as in Figure 17a to c, S7 with ventral lobe having transverse ridge as in Chilicola. aeqiiatoriciisis; genitalia simi- lar to those of C. aequatoriensis but gonoforceps with apex pointed and ventobasal lobe truncate. Female: In addition to usual sexual characters, differs from description of male as follows: Mandible and labrum black. Other pale areas of male less evident, more brown- ish testaceous, hind tarsus entirely dusky. Face about times longer than broad. Punctures of face and vertex somewhat less close, mostly somewhat elongate, with a little shining ground bet\veen them. Preoccipital ridge dis- tant from lateral ocellus by about diameter of that ocellus. Antennal flagellum more than twice as wide apically as basally; third flagellar segment broader than long; middle flagellar segments broader than long. Propodeal triangle with five striae (about seven in specimen from Rionegro) much less irregular than in male, longitudinal rather than diverging as in other species. Holotype male and one female paratype: COLOMBIA: Valle: 10 km west of Call, 1400 m, 19 Sept. 1976 (boll, lireed and Michener, Laiurence). Additional material: COLOMBIA: Autioqiiia: one fe- male.
