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. ADDITIONS TO THE OHIO FLORA. The Fourth State Catalogue of Ohio Plants published in April, 1899, by Kellerman, contained 2025 species of Cormophytes. In the first Annual Supplement, published April, 1900, 69 additions were made. The following 22 additional species therefore bring the total to 2116 plants growing without cultivation in the state. The numbers correspond to the Fourth State Catalogue so that those who desire can easily copy the additions and bring their catalogue up to date. 212a Bouteloua hirsuta Lag. Hairy Mesquite-grass.
