OCOSOCOAUTLA. This is a small town about 50 km. west 
of Tuxtla on the Pan American highway. Collecting was 
done on a forested ridge east of the town. The forest con- 
sisted mainly of evergreen oaks with fair numbers of 
Bursera, but no palms, much resembling a South Florida 
oak hammock. Epiphytes were very abundant. A good 
number of Phlebotomus were taken here from shallow 
buttresses and hollow trees, and a species of Tabanus was 
fairly abundant. Larval ticks fairly swarmed, as cattle 
had access to the forest. Only one visit of a few hours was 
made to this locality, on April 8. 
Palenque. This town is situated in the north eastern 
corner of the state, not far from the border of Tabasco. 
The town itself is small and primitive, surrounded by nearly 
flat sandy country, partly forested and partly open grass- 
land. We took several species of tabanids and Phlebotomus 
in swampy cut-over forest on the outskirts of the town on 
March 28. From that date to April 4 we were encamped 
in the Maya ruins which lie about 9 km. from the town on 
the slopes of a range of low limestone hills. Here we were 
surrounded by practically virgin forest of Humid Lower 
Tropical Zone type with abundant palms. Wild animals 
were quite abundant and monkeys of two genera, Ateles and 
Allouata were easily secured. Tabanids were very abund- 
ant, and good numbers of Phlebotomus and mosquitoes 
were taken. 
Santa Maria. This is a hacienda about 51 km. north or 
north east of Cintalapa by road, about 35 km. airline, sit- 
uated on the Rio Sta. Maria, a tributary of the Rio Grijalva. 
At the time of our visit there was a sawmill operating here, 
owned by the Coabas de Chiapas, S.A. where we made 
headquarters from April 10 to 19. The sawmill itself is 
said to be at an elevation of 800 metres and is in a narrow 
valley at the confluence of two small streams. Immediately 
adjacent to the sawmill the vegetation is of Arid Lower 
Tropical Zone type. Across the Rio Sta. Maria, the land 
rises steeply to a high ridge, the slopes clothed with heavy 
forest of Humid Lower Tropical Zone type with much 
mahogany and cedro, which was being cut for the sawmill. 
We made camp in this forest at a place called La Puerta,
