Anal vein visible as a separate vein from base of wing outwards, con- tiguous with the posterior margin up to Ac Superfamily Hemiphlebioidea Till.

Superfamily Hemiphlebioidea Tillyard. (Figs. 12, 13.) Antenodals two in number only, of which the distal one is situated proximal to the level of the arculus; no alignment of any postnodals with cross-nervures posterior to themselves; discoidal cell of forewing open, that of hindwing closed; subdiscoidal cell fully formed; anal vein partly fused with posterior margin of wing basally, but separating from it just before the anal crossing (Ac) which forms the basal side of the subquadrangle. Family Hemiphlebiidae Tillyard. There is only one family, the Hemiphlebiidae, containing a single genus, Hemiphlebia Selys, with a single species, H. mirabilis Selys, confined, so far as is at present known, to a single habitat on the Goulburn River, near Alexandra Victoria, Australia (ix). (ix) The types of this species are stated by Selys to have come from Port Denison, Queensland (received from, M. Weyers), and the same locality is given for types of Synlestes weyersi Selys.
