collar, a short, broad stripe each side and antehumeral 

 ray, spatulate above, olive ; sides paler, with an oliv- 

 aceous stripe beneath each wing, olivaceous below ; 

 wings hyaline, veins and costa black, pterostigma 

 reddish brown, 5 millim. long; membranule very 

 narrow, whitish ; legs black. Abdomen black, 8 and 

 9 strongly dilated, 9 almost as long as 8 + 10 ; 1, 2, 8 

 and 9 olivaceous on the sides, 1-8 with dorsal yellow 

 spots as follows : 1, apical, triangular ; 2, lanceolate, 

 nearly the entire length ; 3, 4, 5 and 6, basal, oblong ; 

 7 and 8, basal, triangular ; appendages black, divaric- 

 ate, superiors longer than 10, acute, depressed, 

 slightly turned up at apex and having eight or ten 

 minute crenulations on the lower, outer edge apically, 

 inferiors not quite so long, hamulate at apex. 



The female differs in the abdomen being much 

 stouter, 8 and 9 not dilated and in the possession of a 

 small notch in the middle of the occiput. The vulvar 

 lamina is very short and rounded at the apex. 



The species has been taken at Sugar Grove and 

 Akron in September. Four specimens were captured 

 and many more seen at Sugar Grove, September 4th, 

 1894. They were observed flying late in the after- 

 noon, and ovipositing in a small brook that was 

 rippling over pebbles. They continued to fly until it 

 was so dark that the eye could not follow them. 

 Pairs at rest ; the female oviposits in a manner 

 similar to that of the Libellulas. 



Gomphus plagiatus, Selys. . 



Note — Regarding the identity of Ohio specimens 

 which I believe to be plagiatus, at the present time, 

 there is some doubt. This species and notatus are ap- 

 parently very close. Dr. Calvert has kindly sent me 

 specimens of plagiatus taken in Texas. A dozen 

 specimens taken at Sandusky June 20, '96 and referred 

 to by Prof. Kellicott in Jour. Cin. Soc. Nat. Hist. XIX,
