T h e Haglidae comprise the subfamilies Elaglinae, Isfaropterinae, Cyrtophyllitinae, and Prophalangopsinae. During the upper Jurassic, according to Sharov (1971), species of the last-named subfamily were the most numerous, not only among the Haglidae, but perhaps among all the saltatorial Orthoptera. Today the Haglidae are represented only by Propha1nngopsi.s obscura (F. Walker) (Prophalangopsinae), known by a single male specimen collected over 100 years ago in "Hindostan" [India], and by the genus (,yphoderris Uhler (Cyrtophyllitinae), with three species (monstrosn Uhler, buckelli I-Iebard, and strepitans Morris and Gwynne) in the northwestern United States and southwestern Canada. T h e genus was recently revised by Morris and Gwynne (1978). T h e phylogenetic relationships of Haglidae with other taxa of Ensifera, as inferred from morphological and fossil evidence, are still a
