flies mostly in the low grounds and not on the uplands like the 

 preceding. 



1 6. Cordulegaster maculatus Selys. 



A female taken in woods, April 21, 1902. 



17. Cordulegaster diastatops (Selys). 



A male taken in woods, April 12, 1902. 



18 Cordulegaster Sayi ? Selys. 



Prof. Needham identifies some Cordulegaster nymphs taken 

 in November, 1901, and January, 1902, as probably belonging 

 to this species.

 Morrison. Selys, Bull. Acad. Belg. (2) xlvi, p. 689. 1878]. 



20 Oidymops transversa(Say). 



One teneral female taken April 22, 1902 ; two nymphs caught 

 in the seine at Poole's bridge, August 18, 1902. 



21. Macromia illinoiensis Walsh. 



One specimen taken July 28, 1899, while it was flying over 

 the uplands ; one nymph caught in the seine at Poole's bridge, 

 August 1 8, 1902. 



22. Macromia taeniolata Rambur. 



A male taken on Walnut Creek, July 31, 1902 ; its actions 

 were similar to those of Progomphus obscums and Dromogomphns 

 spinosus, for which latter species it was mistaken before its 

 capture. A female was taken resting on the small limbs of 

 an oak, August 30, 1902, on the uplands. The female has 

 the triangles of all the wings and the internal triangles of the 

 forewins^s crossed, the male has all of them free from cross- 

 veins. 



23. Tetragoneuria cynosura (Say). 



Tenerals of this species are very common in woods and in 

 sunny spots near woods in the latter end of April ; they seem 

 to stay in such situations for a short time after they have 

 attained their full strength ; what becomes of them later I 

 cannot say, although I have seen a few flying over water later 

 on. Some idea of the numbers of the tenerals can be gained 

 from the fact that I caught 65 specimens of this and the next 

 species in one morning in April, 1902.
