32 Unit cr sit y of Michigan 



meantime, the Fraile was a mill-race-like stream, flowing azva\< 

 from the Zulia to some inland lake or swamp. Seven or eight 

 miles east of town, in the forest, we found nearly dry and 

 very muddy remains of other 'such cafias leading away from 

 the river. Collected April 20-22, 1920. 



On the Fraile, both before and after the rise of water in it, 

 and on the cana in the forest east of the town we found a few 

 specimens of Hetaerina caja and miniata flying together, the 

 former about five times more numerous than the latter. 



22. Fimdacion, Colombia. End of railroad from Santa 

 Marta. Elevation about 50 feet. Rio Fundacion here is a 

 wide, shifting, sand-bottomed river. Irrigating ditches from 

 the river furnished the only other running water at that sea- 

 son. Above town about two miles, on the left bank of the 

 river, was a large, nearly dry and very muddy creek or arroyo 

 with widely-separated pools of stagnant water eight to ten 

 feet wide. Here, associated with Perithemis and Acantha- 

 grion, we collected 'the only Hetaerina seen at Fundacion, a 

 few specimens of caja. Collected at Fundacion January 9-14, 

 1917. 



23. Gualan, Guatemala. A station on the railroad 80.2 

 miles above Puerto Barrios. Elevation, 420 feet. The Gualan 

 River here is a clear, gravelly stream one hundred feet or 

 more in width. Just above the railroad bridge is a small, 

 gravelly tributary of the Gualan. A similar, smaller but more 

 shaded stream is in the forest about a mile and a half below 

 town. Opposite Gualan is the Rio Manuel, a tributary of the 

 Motagua, from which the city derives its water supply. My 

 notes are deficient, but as I recall it the Rio Manuel is fifteen 

 to thirty feet wide, and is a rapid-flowing hill stream. Like 

 the Gualan River, it was not rich in odonate life. Collected 

 June 11-18, 1909.
