Generic and subgeneric only. The author places the (about) 150 
known species in 5 “ genera ” and 23 “ subgenera, ” divided principally 
according to the forms of the eyes, the condition of the anal angle of 
the inferior wings in the males, the terminal abdominal segment in the 
females, the sub-costal nervure, the basal area, &c. The 5 “ genera ” are 
as follows : — Anax (with 2 “ subgenera ” and 23 species), AEschna (with 
13 and 81), Telephlebia (with 2 and 4), Gynacantha (with 4 and 33), and 
Staurophlebia (with 2 and 8). A tabular arrangement of the larger 
divisions, and a geographical summary, are given. 
Anax includes Hemianax , Selys (AS. ephippigera , Burm.), and Anax , 
Leach (A. formosus , &c.). AEschna includes Anaciceschna , Selys ( A . 
iaspidea , Burm.), AEschna, F. ( juncea , L., &c.), Epicesclina, Hag. {AE. 
heros , Say), Brachytron } Evans {AS. pratensis , Mull.), Acanthceschna , Selys 
(undescribed Australian species), Austroaischna , Selys (A. parvistigma , 
Selys), Gomphceschna , Selys (Gyn. furcillala, Say), Allopetalia , Selys (A. 
pustulosa , Selys, and AS. armata, Hag.), Basiaischna , Selys ( AE.janata , 
Say), Fonscolombia , Selys ( AE . irene, Fonsc., &c.), Amphiaschna , Selys 
{AS. ampla , Hag.), Galliceschna , Selys (AE. microstigma , Schnd.), and 
Cephalceschna , Selys (0. oi'bifrons, Selys). Telephlebia includes only 
Telephlebia , Selys (T. godeffroyi, Selys). AEschnophlebia, Selys, is also 
based on a single subgenus, and on 3 new Japanese species. Gynacantha , 
Ramb., includes Tetracanthagyna , Selys (G. plagiata, Waterh.), Triacan- 
thagyna , Selys ( G . trijida, Rbr.), Gynacantha , Rbr. (G. nervosa , Rbr., 
&c.), and Heliccschna, Selys ( Il.fuliginosa , Selys). Staurophlebia , Brauer, 
includes Neurceschna , Selys (A57. costalis , Burm.), and Staurophlebia, 
Brauer (A£. reticulata , Burm., &c.). 
Anax longipes, Hagen. McLachlan, Z. c. p. 129, has notes on the sup- 
posed example of this in the Science and Art Museum, Dublin.
