Stenoperla , n. g.

Palpi maxillares articulis basalibus duobus brevibus, aequalibus, latis, caeteris planiusculis, 3° et 4° singulis 2° duplo longioribus, 5° 4° breviori. Antennae breves, graciles. Ocelli très. Abdomen gracile, caudis analibus brevibus, gracilibus. Alae quiescentes corpus circumvol ventes: anticae per-angustae, elongatae, venulis transversalibus numerosis regulariter instructae: posticae anticis triplo latiores, plicatae, venulis transversalibus ubique regulariter instructae.

Type.— Chloroperla prasina, Newman , The Zoologist, 1845, p. 853, 2; Hermes prasinus, Walker , Cat. Neurop. Brit. Mus. pt. 2, p. 206, 10; from New Zealand.

n the form of the maxillary palpi, and in the numerous trans­ verse veins distributed pretty evenly over the whole of the pos­ terior wings, this genus approaches Eusthenia of Westwood. n repose the wings form a nearly complete cylinder concealing the body, as in Leuctra.
