II. LAKE PHALEN, ST. TAUL, MINNESOTA, JULY 8. 



This is a small lake northeast of St. Paul and partially outside the 

 city limits. Its western and northern shores are covered with prime- 

 val woods, while the southern and eastern banks are low and swampy 

 in places and clothed with dense underbrush. At the northwest 

 corner the lake is connected Avith another much smaller lake or pond 

 by a short stream which winds through an intervening strip of low 

 marshy ground. 



The banks of the smaller pond are densely wooded, except a narrow 

 strip along the shore and around the outlet. 



On the stream connecting the two bodies of water and around the 

 shores of the smaller pond the dragonflies were especially abundant, 

 and most of the species recorded were collected there. 



The species of T etrag oneuria was the one most abundant on Lake 

 Phalen itself. 



1. ANAX JUNIUS (Drury). 



Fairly coiuuiou around the shore; several seen closely enough for satisfac- 

 tory identification, l)ut none caittured. 



2. .ffiSHNA JUNCEA VERTICALIS (Hagen). 



Fairly conmiou ; a female caught off the side of the trolley car just as it 

 stopi^ed; body very beautifully colored when alive, but fades almost 

 immediately after death; actively feeding along the shore rather than 

 over the water.
