The most important point to notice in this genus is the undoubted presence of the oblique vein and elongated bridge of the Lestidae. Further, since this bridge-vein is continued back to join M<, instead of Mj^_2, we must place the genus in close relationship with the Synlestinae. Its relationship to this latter subfamily seems to be closely sinsilar to that which Epiophlebia bears to the Lestinae. The only other Liassic genus, Protomyrmeleon, is an extra- ordinary

Its relationship to this latter subfamily seems to be closely sinsilar to that which Epiophlebia bears to the Lestinae. The only other Liassic genus, Protomyrmeleon, is an extra- ordinary aberrant Zygopterid, with Sc reduced to a mere remnant. It seems to have had no near allies, and certainly left no descendants. Probably it was the last of some Protodonate side-branch. It is perhaps fitting to record here the recent discovery of a beautiful Dragonfly wing from the Ipswich coal-measures of Queensland (Trias-JuraV I have named it Mesophlebia anti- nodalis (fig. 160), placing it in a new subfamily Mesophlebiinoe, probably belonging to the Anisoptera.
