2 COSTA RICAN DIPTERA 



Hacienda El Brazil, at least one mile north of the town. Alti- 

 tude about 3100 feet. Country rolling, well watered, mostly 

 pasture land or coffee plantations, trees scattered singly except 

 where they form fringes along the numerous small rivers and 

 streams (Rio Ciruelas, Rio Brazil, etc.). Rio Segundo is a river 

 (and a station on the railroad) east of Alajuela. 



Banana River. — The collections of November 9, 1909, were 

 made near the upper reservoir for Limon, situated on the left bank 

 of the river above Bearesem West farmhouse of the United Fruit 

 Company, altitude 100 feet or less. Forest (with many small 

 palms in the undergrowth) comes down to this reservoir. The 

 whole region is mostly flat with occasional hillocks and in large 

 part occupied by bananas, but patches of forest remain here and 

 there. 



Cachi. — A small town on the right bank of the Rio Reventazon 

 east of Cartago, southwest of Juan Vifias. Considerable coffee 

 raised around the town, higher up are pastures, still higher on the 

 hills south and southeast is forest. Altitudes at which collections 

 were made from 3450 feet (at bank of Rio Reventazon) up to 4000 

 feet. There are three well-marked river terraces, the lowest form- 

 ing a strip of beautiful meadow with some old forest trees. A 

 few miles west of Cachi, the Reventazon winds through a stretch 

 of cobble-like stones and sand in several channels; collections made 

 here on March 7, 1910. 



The Rio Oro is a tributary (on the right bank) of the Reventazon, 

 a little west of Cachi. The vegetation of its valley was quite 

 dense, many forest trees still standing, tree-ferns 15 feet high, 

 phyllodendron on tree trunks, Aroids, etc. (March 8, 1910). The 

 Rio Naranjo, also a tributary (on the right bank) of the Reventazon, 

 is east of Cachi. Where we collected it flows chiefly through open 

 pastures. 



La Carpintera. — Mountain having several peaks, highest 

 5700 feet elevation, bounding valley of Guarco (in which Cartago 

 lies) on the west and forming the divide between the Atlantic and 

 Pacific slopes. There is still some undisturbed forest on it, but 

 not on the area collected over on December 4, 1909. 



Cartago. — Town (of 8000 population previous to earthquake 

 of May, 1910), on Costa Rica Railroad. Altitude 4750 feet. 

 Near the top of the Atlantic slope as traversed by the railroad.
