306 ENTOMOLOGICAL NEWS. [July, ’o8 
the swamp up to July 13 after which date no individuals were 
seen. On bright mornings when the eastern sky was un- 
obscured they were hunting low over the western side of the 
marsh at 4.45 o’clock. One cloudy morning they did not ap- 
pear at all. After 9 or 10 o'clock their visits to the marsh were 
rare and they were more wary, leaving the marsh when any 
effort was made to approach them and flying directly to or 
above the tree tops. When searching for food early in the 
morning they are less wary than I have ever seen Aeshna con- 
stricta which frequents the same marsh in autumn, and which 
is most actively on the wing in bright weather from 10 A. M. 
to 2 P. M. Aeshna mutata spends most of the day after 9 or 
1o A. M. either resting in the trees or flying about over the 
tree-tops, very probably the latter. As is usual in the genus 
the night is spent clinging to the tree trunks or larger limbs at 
some elevation. 
At an undrained button-bush swamp five miles north of Bluf- 
fton, two males of Aeshna mutata were seen and captured on 
June 30. Several Libellula vibrans were flying at this swamp 
but no Libellula quadrimaculata were seen. At a swamp four 
miles north of Bluffton which much resembles the Vanemon 
Swamp, and where Sympetrum albifrons has been taken, on 
June 30 Libellula quadrimaculata was so abundant that 43 
specimens were caught in possibly half an hour, though they 
are not easily captured. At this swamp also in autumn, as at 
the Vanemon Swamp, Aeshna constricta is not rare. But 
Aeshna mutata was not taken at this swamp which in general 
resembles the Vanemon Swamp much more than does the but- 
ton-bush swamp. Of these three swamps I have collected at 
the Vanemon Swamp most and I am reasonably sure that 
Aeshna mutata has not hitherto frequented this swamp since 
1g00. As to the appearance here for the first time in 1907 of 
the three species of Enallagma (cyathigerum, calverti and 
aspersum) and two species of Libellula (quadrimaculata and 
vibrans) I am even more convinced than in the case of Aeshna 
mutata.
