De SELYS-LONGCHAMPS (Compt.-rend. Soc. Ent. Belg. 5 Nov. 1870) gives
an outline of the arrangement of these insects adopted by him in his forthcoming
" Synopsis des Cordulines." He divides them into two "Legions,"
Cordulia and Epophthalmia. Cordulia comprises three "genera," Cordulia,
Epitheca, and Cordulephya. The genus Cordulia, again, is separated into two
" subgenera," Hemicordulia, Selys, and Cordulia, Leach (restricted) : Epitheca
comprises three " subgenera," Epitheca, Charp., Oxygastra, Selys, and Gomphomaeromia,
Brauer. Epophthalmia is divided into four " genera,' Idionyx,
Synthemis, Epophthalmia, and AEschnosoma. Epophthalmia is again divided
into two "subgenera," Epophthalmia and Maeromia. The terms Hemicordulia,
Oxygastra, Cordulephya, and ^Eschnosoma represent new divisions or,
as the Recorder prefers to term them, genera. Some new species are indicated,
but not described.
