The localities from which specimens were obtained are cited below and
shown on the accompanying map (Fig. 1).
[Illustration: FIG. 1. Map of El Peten, Guatemala, showing localities
mentioned in text.]
Chinaja.--Lat. 16 deg. 02', long. 90 deg. 13', elev. 140 m. Camp of
the Ohio Oil Company of Guatemala and formerly a small
settlement. On some maps Chinaja is located just to the north
of the Alta Verapaz--El Peten boundary; recent surveys place
the location just to the south of the imaginary line through
the rainforest. Field work was conducted in the immediate
vicinity of the camp, on the lower slopes of the Serrania de
Chinaja, and at several sites to the northwest and
north-northwest of Chinaja, where the forest was being
cleared. The entire area supports rainforest.
La Libertad.--Lat. 16 deg. 47', long. 90 deg. 07', elev., 170 m. A
town on the savannas in central El Peten; although we
collected there in the rainy season, the specimens obtained on
the savannas are not included in this report.
Paso Subin.--Lat. 16 deg. 38', long. 90 deg. 12', elev. 90 m. A small
settlement on the Rio Subin, a tributary of the Rio de la
Pasion. Specimens were obtained in rainforest in the immediate
vicinity of the settlement.
Rio de la Pasion.--A large river flowing northward through
southern El Peten and thence westward into the Rio Usumacinta.
Specimens were obtained along the river between the Rio Subin
and Sayaxche.
Rio San Roman.--A river flowing northward in south-central El
Peten to the Rio Salinas (Usumacinta). We collected along the
river at a place about 16 kilometers north-northwest of
Chinaja, approximately at Lat. 16 deg. 10', long. 90 deg. 17', elev.
110 m. In the dry season the river was clear; it is surrounded
by rainforest.
Sayaxche.--Lat. 16 deg. 31', long. 90 deg. 09', elev. 80 m. A town on
the southern bank of the Rio de la Pasion. Specimens were
obtained in the rainforest and in cleared areas in the
immediate vicinity of the town.
Toocog (formerly Sojio).--Lat. 16 deg. 41', long. 90 deg. 02', elev.
140 m. A camp of the Ohio Oil Company of Guatemala located at
the rainforest-savanna edge, 15 kilometers southeast of La
Libertad. Although we collected on the savannas as well as in
the forest, especially to the east of the camp, only species
obtained in the forest are considered in this report.
