(type-locality, Miranda, San Antonio de los Altos). Comments on some of the species are made. Among the Carabids I received for study from Venezuela, are six species of Pentagonica, a genus which has not been previously recorded there (the type-species of Thoasia, the other Neotropical genus of the group, is the only species of Pentagonicini known from Venezuela). I am publishing now the data on the Pentago- nicini, as materiais for a coming revision of the group. The remaining forms will be subject of a commented list to be pubiished in the near future. I have recently pubiished a preliminary revision of the tribe in the New World (Reichardt, 1968). No changes in taxonomic concepts are proposed in the present paper, and therefore no references are given for the species treated. They are given in the earlier revision. It is interesting to note here that ali the specimens studied have been collected in the northern, coastal, states of Venezuela. This most certainly does not mean a restriction to that part of the country, but lack of material from the inland. The following collections were studied: Instituto de Zoologia Agricola, Facultad de Agronomia, Universidad Central de Venezuela, Maracay, Aragua (under care of F. Fernandez Y., C. J. Rosales and J. Bechyné; FAUCV); Museo de Historia Natural La Salle, Sociec!ad de Ciências Naturales La Salle, Caracas, D.F. (under care of L. J. Joly T.; CLS); and the private collection of Mr. C. Bordon, Caracas, D.F. (CB). I am very much indebted to these entorno- logists, who made the collections available for study. Special thanks are due for the permission to retain part of the material in the Museu de Zoologia (MZUSP), and one paratype of the new species for the Museum of Comparativo Zoology, United States (MCZ).

Miranda, La Toma, Capaya, 250 m, 24.III. 1967, J. L. Gracia col. (2 ex., CLS, MZUSP). P. ochracea was originally described from neighboring, and faunistically very similar, Trinidad. In its original description it was considered as related to the species in the vicinity of trivittata, Having now studied specimens of omostigma from Venezuela, the relationships between these t^vo species become very apparent. P. omostigma is, however, easily distinguished by the elytral markings, which are completely absent in ochracea. Pentagonica omostigma Bates, 1883 Venezuela.

Ventrally black, except prothorax, which is testaceous. Measurements (in mm): total length, 4.7-5.6; maximum elytral width, 2.0-2.4; maximum pronotal width, 1.1-1.4. 1 mm 2 Fig. 1: Pentagonica melancholica, sp. n.; fig. 2;P- trivittata. Pentagonica melancholica, sp. n., is well characterized by the peculiar elytral spot; it is closely related to trivittata, a species with wide, but disrupted distribution (see Reichardt, l.c.: 157), and which also occurs in Venezuela. The two species have black head, testaceous pronotum, and the elytra with testaceous ground color, but the elytra are differently marked. 314 Papéis Avulsos de Zoologia Pentagonica trivittata (Dejean, 1831) (Fig. 2) Venezuela.

Venezuelan trivittata agree morphologically with the Central American specimens listed elsewhere (Reichardt, l.c.: 150), that means, they have completely yellow antennae and yellow scutel- lum; while the Brazilian samples I have seen, have segments 5-11 darkened, and black scutellum.
