Discussion. This is placed in the Kalligrammatidae because of its size and the numerous parallel veins with cross-veins. These are regarded as diagnostic and are used to separate the Kalligrammatidae from the Psychopsidae. It differs from Megapolystoechus Tillyard in the main longitudinal veins which run more towards the outer (terminal) margin rather than the posterior margin as they do in Megapolystoechus. Family PROHEMEROBIIDAE Handlirsch, 1906 Although Tillyard suggested that this family was characterized by a large number of branches on the radial sector ('immense development of parallel branches', Tillyard, 1933: 11) this does not fit the original concept proposed by Handlirsch (1906). Tillyard placed genera in Pro- hemerobiidae where there were 20-27 branches on the radial sector, whereas in Handlirsch's original description, and his later usage in 1939, only species with 7-11 branches on the radial sector were included. Martynova (1962) recognized this and removed the genera placed by Tillyard (1933) in Prohemerobiidae. The original definition proposed by Handlirsch is used here with slight modification.
