Prof. Dr. Carlos Berg, Director of tlie Museo Nacional de Bue- 

 nos Aires, having sent me a small collection of Odonata from San 

 Pedro, on the Rio Aguaray-Guazú, a tributary of tlie Jejuy, in 

 Paraguay, witli tlie request tliat I identify them f or him and com- 

 municate anything new or notewortliy cjncerning them; tlie pre- 

 sent paper is the result. 



Some notices of Paraguayan Odonata are contained in tlie sys- 

 tematic works on tliese insects, and M. Rene Martin lias publislied 

 a sliort paper ^ dealing witli a collection made by Dr. Borelli, but, 

 nevertheless, very little is yet known on the Odonate fauna os tliis
