Scudder.] 298 [September 25, 



BsrtJaemis frontalis Burm. was captured while flying back and 

 forth over a stream issuing from the side of the mountain at an ele- 

 vation of apparently more than one thousand feet above the level of the 

 sea. Three males were captured, which were almost entirely lead- 

 blue in color. Time of appearance was in May. It was by no means 

 abundant. 



Dythemis pleurosticta Hagcn. This species was quite com- 

 mon, flying in company with the preceding on the side of the moun- 

 tain. I afterwards saw some specimens along the side of the road, 

 in the valley next the mountain. April and May. 



Mesothemis mithra Ilagen. A single male of this species was 

 captured b}' me near the Grand- Anse River, in May. I saw only two 

 other specimens of this species, which Avere flying with great rapidity 

 over the surface of the river, but my greatest exertions did not en- 

 able me to capture them. Their flight is very rapid and steady. 



My short stay in the Island of Hayti did not allow me to make 

 distant excursions to procure specimens of the insects peculiar to the 

 interior of the country. No sooner do the rains begin than all na- 

 ture seems to spi'ing into life, and could I have remained there until 

 the wet season was over, I am sure that many more sjiecies must have 

 rewarded my pains. 



Additional Remarks upon the Odonata op the Isle of 

 Pines and of the White Mountains of Neav Hampshire. 

 By Samuel H. Scudder. 



Since reading the statements of Dr. Hagen in the preceding pa- 

 per, I have been induced to reexamine the specimens which I used in 

 preparing my papers on the Odonata of the Isle of Pines and of the 

 White Mountains of New Hampshire;* the following remarks give 

 the result of this examination. 



It is evident from the nature of Dr. Hagen's invaluable Synopsis of 

 the NeurojDtera of North America, that the work was not intended 

 for a monograph, and that the short descriptions of genera, and other 

 larger groups which it contains, were only added as convenient dia"'- 

 noses. When my papers were prepared, this work, together with 

 Rambur's Neuroptera and De Sclys's descriptions of Cuban Odonata, 

 were almost the only authorities at my command. Working under 

 such disadvantages, I could hardly help falling into those errors of 

 determination which Dr. Ilagen has pointed out.
