28 Unnersity of M ichujan 



12. Cisncros, Colombia. Terminus of the railroad from 

 Puerto Berrio. Elevation about 3,500 feet. Most of the 

 native flora about Cisneros is gone and the rough, rocky 

 streams, ten to thirty feet wide, are largely exposed to the sun. 

 Our one day's collecting here February 10, 1917, was so unpro- 

 ductive that we explored only one stream, the Rio Santa 

 Getrudis, where we took a single female of Hetaerina 

 in-acrop2is. 



13. Colonia del Perene, on the Rio Perene, Department of 

 Junin, Peru. Elevation, 2,230 feet. At hacienda number one 

 two streams join to form the Perene. One of these, the Rio 

 Paucartambo, has tributaries of varied characters on the right 

 bank just above the suspension bridge. One of these flows 

 through scattered bushes from a boggy spot on the bank of 

 the river. One kilometer above the bridge is a very small, 

 rocky quebrada. Near hacienda number one is the quebrada 

 Repressa, two to four feet wide, with many waterfalls. Near 

 hacienda number two is a larger and slower quebrada flowing 

 into the Rio Perene. Below and east of hacienda number one 

 is an old river bed of the Perene, where there are large pools 

 and a little running water, and where dragonflies were very 

 abundant. On the road to San Juan, past hacienda nimiber 

 two, are some small quebradas. Collected June 4-22, 1920. 



Hetaerina macropus is represented by only three males 

 taken on the wooded part of a quebrada on the trail from 

 hacienda number two to San Juan. On the quebrada Repressa 

 and on the quebrada flowing into the Rio Perene near hacienda 

 number two both cliarca and sanguinea were taken, but at the 

 old river bed only sanguinea was found ; and at the very small, 

 rocky quebrada one kilometer above the suspension bridge and 

 at another similar quebrada aljove charca was found. Thui
