from The Century Dictionary and Cyclopedia
- In entomology, a division of orthopterous insects, corresponding to the Linnean genus Gryllus, including those which are saltatory, having the hind legs fitted for leaping, as the Gryllidæ, Locustidæ, and Acridiidæ, or crickets, grasshoppers, and locusts: originally one of two sections (the other being Cursoria) into which Latreille divided the Orthoptera.
Sorry, no etymologies found.
Anybody who has experience with living walking sticks recognizes their obvious kinship with saltatoria i.e. grasshoppers and similar insects.
Disk: the central upper surface of any part; all the area within a margin; the central area of a wing: in Trichoptera, the obliquely ridged outer surface of hind femur in saltatoria.
"_chrysomela oleracea_, _saltatoria_, _femoribus posticis crassissimis_."
