have seen specimens from the upper Wisconsin River, and from 
Texas, and many localities between these, and pup also from Kan- 
sas. 
36. Gomphus exilis Selys. Hag. Syn, 108, 23. ° 
No.4. 6 ¢, June, 1821, and Dr. Smith, Sutton. Ae. fraterna Say 
Mss. (Say’s determ.). 
The specimens are surely not Say’s Ae. fraterna, as the deserip- 
tion and size do not agree, though Mr. Say himself named them. 
Say’s types were not from Massachusetts, nor were they communi- 
cated to him by Dr. Harris. Apparently his determination was made 
later and was an error of memory. 
37. Cordulegaster Sayi Selys. Hag. Syn., 115, 1. 
No. 73. 4, Ae. obliqua Say Mss., var. (Say’s determ.). 
Note by Dr. Harris: —“ Say thought it a variety of his obliqua 
but it is a different species.” Randal, Stow, Mass. 
Say describes a male variety of his Ae. obliqua, sent by Dr. Harris. 
Of course the male in the collection is the type, agreeing with Say’s 
diacnosis. ‘The type of C. lateralis Scudder is identical with Harris’ 
specimen. In my Synopsis I erroneously referred Say’s variety to C. 
maculatus. 
38. Cordulegaster maculatus Selys. Hag. Syn., 115, 2. 
There is in the collection a male specimen, No. 73, not indi- 
eated in the catalogue, perhaps a later addition, belonging to this 
species. Both species seem to be rare. 
A fragment of a Gomphus nympha, without label, is in the collec- 
tion. 
CALOPTERYGINA. 
39. Calopteryx maculata Beauv. Hag. Syn., 57, 4.
