Central America has a rich Hetaerina fauna with sixteen 

 known species. All five of the Colombian species listed in this 

 paper occur also in Central America; the four Venezuelan 

 species occur in Colombia and Central America ; and the two 

 species known from Trinidad also are common to Central 

 America, Colombia and Venezuela. But of the three Peru- 

 vian species before me, only one occurs also in the material 

 from the re^ons mentioned in the preceding sentence; and 

 the four species from British Guiana are not represented at 

 all in material from the other regions. 



Awaiting a careful study of the relationships of the Hetae- 

 rina species, such as Dr. Kennedy has recently made of the 

 Libellula species (Entomological News, XXXIII, March and 

 April, 1922), the species here discussed are arranged alpha- 

 betically in the text. 



These fifteen species of Hetaerina are alphabetically 

 arranged and consecutively numbered in the list below. Under 

 the discussion of each species, following each locality, are 

 numbers in parentheses indicating the other species of Hetae- 

 rina taken in that locality. For example, under H. americana, 

 Guatemala, Agua Caliente (5, 9), indicates that at Agua 

 Caliente, in addition to americana, cnientata and inacropus 

 were taken. The species are : 



1. H. americana 9. H. macro pus 



2. H. caja 10. H. ininiata 



3. H.capitalis 11. H.moribunda 



4. H. cJiarca 12. H. mortuu 



5. H. cruentata 13. H.pilula 



6. H. dominula 14. H. sanguinea 



7. H.fiiscoguttata 15. H.titia 

 S. H. laesa
