Alphabetical, List of Localities where Collections 

 WERE Made 



Generally, only Hetaerina habitats are described for each 

 locality, so the discussion under each locality is in no way 

 indicative of the presence or absence of other nearby dragonfly 

 habitats. 



I. Agiia Caliente, Guatemala, on the Rio Agua Caliente, 

 a swift, stony headwater of the Alotagua, where the railroad 

 crosses it 20.2 miles below Guatemala City. Width about 

 fifty to one hundred feet. Elevation about 3,200 feet. Col- 

 lected June 1-2, 1909. 



Along this swift and stony river were three species, Hetae- 

 rina americana, crtientata, and macroptis. Unfortunately, my 

 notes give no data as to the distribution of the species on 

 the stream. All of the species are well represented in the 

 collection, macropus by about as many specimens as the other 

 two, which occurred in equal numbers. 



2. Amatitlan, Guatemala. A town on the river draining 

 Lake Amatitlan. Elevation, 4,212 feet. The river is clear, 

 rapid and gravelly, and the only Hetaerinas seen at Amatitlan 

 were collected on this stream. Collected June 7-10, 1909. 



Of the seven specimens taken here, six are Hetaerina 

 amcricana and the remaining specimen is cnientata. 



3. Aracataca, Colombia. On the Santa Marta-Fundacion 

 railroad, near the Fundacion terminus and about fifty-five 

 miles from Santa Marta. Elevation probably about fifty feet. 

 Collected at irrigating ditch near fruit company station for 

 only a short time on Januar)^ 9, 1917, and a single male of 

 Hetaerina caja was taken. 



4. Arima, Trinidad. Most of our collecting in Trinidad 

 was done at two small rivers reached by electric lines from
