88 Journal New York Entomological Society. [Voi. v. 
ness of Dr. D. S. Kellicott, and Mr. P. P. Calvert has kindly under¬ 
taken to revise the list and publish it in connection with his additions to 
the list of Dragonflies of New York State : 
Calopteryx maculata Beauv. This pretty insect makes its home 
in deep woods and in gullies among the hills where a rift in the foliage 
admits the sunlight to the little pools that form along the hill-side 
streamlets. Here they often congregate in great numbers on the bushes 
overhanging the water. On the level country about Buffalo this species 
is rarely seen and then only near water in the heaviest woods. 
Lestes uncata Kirby. June to August. I have taken this species 
only in boggy woods where the water rarely if ever dries away during 
the summer. In such situations it flies about the swampy openings 
where the hot rays of the sun make the mosquitos lively and the collec¬ 
tor miserable. 
Lestes rectangularis Say. Not common. Taken near deep 
stagnant streams in August and September. 
Argia putrida Hageti. Through July and August this species is 
common along some of our smaller creeks where a rapid current is bro¬ 
ken by projecting stones. I have never seen it near still water as re¬ 
corded by Dr. Kellicott. 
Argia violacea Hagen. Rare. Taken in company with the pre¬ 
ceding species in August. 
Erythromma conditum Hagen. Taken flying over a ditch of 
running water at Hamburgh, N. Y., in June. 
Amphiagrion saucium Burm. Common about swampy places 
through July and August. 
Enallagma carunculatum Morse. Very abundant from late 
June to September on Squaw Island in Niagara River and along the 
shores of Lake Erie where the shallow water is overgrown with reeds. 
Enallagma hageni Walsh. Squaw Island, June nth, two ex¬ 
amples. 
Enallagma exsulans Hagen. Taken immature at Black Rock 
Harbor about June ist, and mature, in July in a bog swamp at Clarence. 
Enallagma signatum Hagen. Numbers taken along a sluggish 
creek north of Williamsville in September. 
Ischnura verticalis Say. This is the most abundant Agrion 
about Buffalo. It occurs in immense numbers on Squaw Island and 
along Niagara River and the shores of Lake Erie where fields of rushes
