Описание: The various genera and species of the Orthopteran sub-family Tet- tigidae may be recognized under several names in the reports of a number of entomologists. They range from the form Bulla of LINNE (1767), whose figures are unmistakable, to the recent descriptions of SCUDDER (1900), HANCOCK (1902), and other orthoptologists. Such words as Tettix, Tettiginae and Tettigidae apparently were derived from "tettix" of Greek origin, meaning grasshopper. The common name, "Grouse locust," has probably been applied because of a fanci- ful resemblance of some of these insects to the grouse (Tetraoninae).

The following discussion con- cerning the characteristics which distinguish the Grouse Locusts is largely from the detailed descriptions by HANCOCK (1902) and Ro- BERTSON (1915). (See Fig. I).
