quent but short visits to the rapids of the stream where its 
nymphal life was passed. With swift flight it drops from its 
sunlit leaf to a boulder, log or bit of smooth sand. It moves 
from one station to another by short flights, rendered invisible to 
the collector because of its swiftness and the agitated waters over 
which the insect passes. After a few moves it throws itself 
boldly into the water from which it arises to seek again its leafy 
and frequently lofty perch. When the late afternoon sun 
bathes with vertical rays a leafy wall of vegetation on the edge 
of some swift ripple where the crane flies are dancing in the 
spray, carolus forgets the heights of forest trees and catching its 
prey with ease, feeds and basks on a swaying leaf, from which it 
springs to flit the ripple and return again. The sun sinks lower, 
the forest shadow creeps across the ripple and up the alders, and 
the green mite of most animate nature rises with the shadow into 
the safe retreat of forest trees. 
12. Gomphus sordidus Hagen. Heyden, July 31st, one 
female. Along Root River at different ripples on two occasions 
I saw males of a species of Gomphus which I thought was brevis. 
The abdomen was colored and held aloft exactly like this species. 
Also along Root River I saw close at hand a female Gomphus 
which I believe was exilis. 
13. Gomphus scudderi Selvs. Searchmont, Aug. 1, G, 7, 8 
and 9th. Fifty-two males; no females were seen; along the 
Goulais and its tributaries this was the commonest dragonflv. 
When resting on smooth sand, boulders or logs it is approached 
with difficulty; when resting on vegetation it may usually be 
taken with ease. It is a restless busy body, its flight swift but 
not well balanced or long sustained. One on occasion one flew 
swiftly toward me and alighted on my shoulder. A slight 
motion on my part caused it to take to sudden flight. On 
another occasion one alighted on the back of one hand. The 
other hand was brought slowly and carefully up and a fore and 
hind wing seized between thumb and Anger. Several males of 
this species were distinctly seen at Oden, Mich., but were not 
captured. 
Dromogomphus spinosus Selys. Oden Mich. Aug. 14th. 
J. H. Williamson. One male. 
14. Lanthus albistylus Hagen. Searchmont, Aug. 8th; two 
males. This species was also distinctly seen at a ripple in Root 
River, but no specimens were taken there. The two taken were 
at the same ripple at Achigan Brook where one or two more 
were seen. No other specimens than these mentioned were seen 
during the trip. 
15. Hagenius brevistylus Selys. Heyden, July 31st and 
Aug. 2d; Searchmont, Aug. 8th. Four males and one female. 
One male taken Aug. 8th was the onlv individual seen in the
