Up to this time seven species only have been described by H. Hagen. One from 
Brazil, Gynacantha spec.; the others from Europe, Anax formosus; Aischna rufescens, 
grandis, cyanea, affinis; Brachytron pratense. 
There have been figured before, — 
Anax formosus; Muralto; Drury? Evans; Dufour. 
“Eschna cyanea; Swamerd? Frisch? Reaumiir; Donov; Dufour. 
AXschna mixta; Reaum ? 
A®schna grandis; Roesel; De Geer; M. Harris. 
/®schna rufescens ; Dufour ? 
Eschna constricta ; Sanborn. 
In all six species, three only, however, are recognizable, and none of the figures are 
accurate enough for specific determination. Of the twenty-four species now described 
and figured, containing the types of the seven species described by H. Hagen and 
others, there are of 
Europe, nine. 
America, nine; seven from U. 8. A. 
Asia, four. 
Africa, one. 
Half of the species described were raised, viz. the nine European species and three 
United States species. The actual number of described species of Aschnide has not been 
exactly ascertained, but the twenty-four immature states given are about one tenth. In 
the United States there are twenty-one species known; of these, seven in the immature 
state are given. In Europe, thirteen are known; of these, nine in immature states are 
given. To make any general remarks on the classification of Gomphina and A®schnina 
has been found impossible, until the Libellulina and Cordulina have been described.
