/evis still more than in males, since none of the females 
of rugulosa before me has distinct lateral stripes, which are 
quite characteristic for /evis and may be seen in males of 
rugulosa as well. The chief distinctions are, however, not in 
coloration, but in general habitus, sculpture of face, length 
of elytra, and shape of hind femora. 
Subfamily Prreomorrurnz. 
PreRORTHACRIS, gen. nov. 
Body cylindrical. Antenne filiform, rounded, except 
joints 3-5, which are distinctly depressed and very feebly 
dilated. Head conical, less elongate than in Orthacris, Bol.; 
front in profile almost straight, scarcely protruding between 
antenne; frontal ridge between antennez compressed, deeply 
sulcate, gradually lowered towards ocellum ; below the latter 
it is expressed only as a shallow sulcus with scarcely raised, 
obtuse margins and does not reach the clypeus ; lateral 
facial carine well-developed, divergent downwards, slightly 
convex ; fastigium of vertex in profile much shorter than an 
eye; its surface forming a straight angle with frontal carina, 
convex ; seen from above it is a little longer than broad, 
with apex circular, intersected by deep and narrow longi- 
tudinal sulcus, and separated from the rest by a semicircular, 
not sharply defined, impression ; margins of fastigium between 
the eyes subparallel ; the whole of this part of the fastigium 
slightly convex, with a scarcely perceptible median carina ; 
its level slightly raised above the fore part and slightly lower 
than occiput. Eyes almost hemispherical. Pronotum 
entirely rounded, narrowed anteriorly, with a few rather 
large and low scattered callous tubercles; median carina 
feebly developed in metazona only; pronotal disc intersected 
by two deep narrow sulci and a faintly indicated anterior 
sulcus; metazona shorter than prozona; anterior margin 
with a slight excavation in its middle; posterior margin 
widely rounded ; lateral lobes longer than high, narrowed 
anteriorly. Prosternum armed with a conical tubercle. 
Sternum compressed, elongate; its fore margin teebly 
convex ; mesosternal lobes distinctly longer than wide, 
subtriangular, with the inner margins rounded, meeting 
each other near the apices, which are acute, rounded; hind 
margins of mesosternal lobes concave ; interspace very 
narrow-triangular, with all margins concave. Metasternal 
' foveole large, rather closely approximated; metasternal 
lobes contiguous. LHlytra fully developed, lancet-shaped,
