I noted of Hetaerina cruentata that it occurred along the 

 stream where it emerged from the hills, but whether or not it 

 also ranged back into the hills my notes do not show. It was 

 back in the hills that I found macro pus, miniata and capitalis, 

 but again my notes fail to show if there was any local distri- 

 bution of these species on the stream. The following num- 

 bers of specimens of each species were taken and will indicate 

 in a general way their relative abundance : cruentata 46, macro- 

 pus 10, miniata 123, capitalis 9. 



42. San Ramon, Department of Junin, Peru. Elevation, 

 2,800 feet. One kilometer from San Ramon, across the Rio 

 Chanchamayo, is a small, sandy-bottomed creek one to two 

 feet wide, flowing through cleared land and banana plantings. 

 Near San Ramon is the small quebrada Apurimae, flowing 

 through open country in corn and bananas, with bushes on 

 the creek's bank. The creek bed is mud, sand and boulders. 

 Collected July 12-15, 1920. 



Hetaerina sanguinea was the only species observed on these 

 streams. 



43. Santa Marta, Colombia. On the coast. The Manza- 

 nares River and its tributary, the Tamacal, were here largely 

 exposed to the sun and flowing generally over beds of fine 

 sand. Collected here December 13-19, 1916, and January 3, 

 1917. 



Three specimens of Hetaerina macro pus were taken along 

 small streams in a woods along the railroad track and adjacent 

 to the Tamacal. Everywhere else the only species found was 

 caja, which was common. 



44. Santo Tomds, Guatemala. On the coast. Near town 

 a large spring forms a pool of water at the foot of a hill. 

 From this spring a short stream flows into the nearby gulf. 

 Collected May 29, 1909.
