Some remarks xjpon the Odonata of Hayti. By P. R. Uuler. 



The foregoing paper of Dr. Hagen affords me a welcome oppor- 

 tunity to remark upon some of the Dragon flies wliich I observed and 

 collected in Hayti, while there engaged in collecting specimens of 

 Natural History for Prof. Agassiz. 



AGRIONINA. 



No species of Lestes, Calopteryx or Hetaerina Avere seen by me in 

 Hayti, although they might have been found there about the begin- 

 ning or end of the second rainy jieriod, in September or October. 

 The Gi-and-Anse River is full of small rapids, and the banks are 

 covered in places with bushes and vines projecting over the surface, 

 furuisliing those delightfully shady spots which such insects are wont 

 to frequent. 



Anomalagrion hastatum Hagen, was met with behind a strip 

 of land projecting into t-he Grand- Anse River, where the water was 

 still and crowded with pond lilies. 



Agrion Dominicanuni Selys, Avas first captured while it was 

 holering over a brook issuing from a spriiig, high up the side of the 

 Cote de fer, about three miles from Jeremie. I next found several 

 specimens fl}ing about the edge of a marsh near the road leading 

 along the Grand- Anse River. The times of its appearance were in 

 April and jNlay. 



Several other sjDecies of Agrion were captiu'cd about the surface of 

 the river, but I have not yet been able to ascertain their names. 

 The Grand- Anse is full of shallow places having a muddy bottom, 

 and there the pond lilies grow in great abundance; on the leaves of 

 these plants the Agrions delight to settle, and there they can be taken 

 in the greatest numbers. 



GOMPHINA. 



A single specimen of Gomphoides (the species is not known to me) 

 was procured at a spring high uji the side of the mountain beyond 

 Jeremie. It was flying backward and forward over the stream issu- 

 ing from the spring, and the colors were dark brown and light green. 

 No species of Goinphus was met with upon the Grand-Anse River, 

 although there were many places such as they are accustomed to fi'c- 

 quent, and notwithstanding my thorough search for them. 



iESCHNINA. 



^schna virens Ramb. I was unable to capture the only speci- 

 men that I saw, which was flying with great rapidity near the road
