During the week beginning June 17th, we collected insects and fishes in

the region of small lakes near Kent, Ohio. A list of the Odonata taken

during that week is interesting, as it shows the richness of the Odonat

fauna of north-eastern Ohio and also the number of species of this group

that may fly in a certain locality at the same time.

Number 2 was taken for the second time in the State. The species was

common along the Cuyahoga River, where both males and females were found

resting on foliage near the water’s edge or flitting nervously from one

resting place to another.

Number 27 is one of our rarer Gomphids. Only one specimen of the species

was taken.

Both male and female of 30 were taken. This is the first time the female

of this species has been taken in Ohio.

Number 39 was taken for the first time in Ohio. Three pairs of this fine

species were taken.

Two years ago I took males of number 48 at Stewart’s Lake. The species

has not been taken in the State since until this year when we took both

males and females at the same lake.

Number 53 has been considered a very desirable species, but it seems

that it is a common form in the lake region near Kent. About thirty

specimens were procured.
