sternum are narrow, depressed in the middle, the coxae surrounded 

 by distinct ridges; the metasternum entirely obliterated by the 

 coxse of the hind legs. 



Legs slender, long ; the posterior pair about two and a half 

 times the length of the body, more or less angular, Tibitv of all 

 and the femora of the hind legs spiny. Tarsi four-jointed, stout ; 

 claws long and slender. Auditory areolet oval, large, free. 



Abdomen compressed, subconical, twice the length of head and 

 thorax together ; segments, ten dorsal and eight or nine ventral, 

 former along medial line overlapping and forming acute points ; 

 ventral plates subquadrate, surrounded l)y a narrow ridge. Anal 

 plate deeply emarginate ; cerci short, finely ciliate, and curved 

 inwards. 



Tegmina and wings more than twice the length of the body ; 

 slope very steep, except that of the interior area of the tegmina,, 

 which alone is horizontal in repose. The latter are thin, leathery, 

 translucent, convex in front, concave behind, nearly of equal width 

 througliout, tips rounded, border oblique ; the costal area is 

 broadly lanceolate near the l^ase, contracts rapidly, and then nar- 

 rowly linear to the tip ; the inferior area is triangular, Ijroad at 

 the base, but short, being scarcely one-fifth of the total length of 

 the tegmina, and almost wholly occupied by the stridulating ap- 

 paratus, censisting of several strong longitudinal veins (with 

 slighter ramifications through the transparent membrane) in the 

 right wing, and a very stout transverse vein, with some smaller in 

 the left one. The discal area is several times larger than the others 

 together, and nearly of the same width throughout, except near 

 the base. Subcostal vein very sti'ong, transverse branches stout, 

 often in pairs, ultimate reticulations very numerous, meshes ir- 

 regular. 



Hindwings somewhat longer than tegmina, transparent, and 

 delicate ; tips rather acute, border very oblique, interior margin 

 short ; thirteen almost straight radiating veins, of which only the 

 subcostal emits oblique branches, all being connected by mostly 

 rectangular, simple, more or loss straight transverse branches. 



Hectoria Pontoni, sp. nov. 

 Pale dull green. Eyes dark brown, shining. Crest yellowish- 

 green, margin deep brown to black. Tegmina, costal area with 

 obliquely transverse brown lines and spots ; discal area with nine 

 or ten short broad transverse brown bars (some double, others 

 irregular) between the subcostal and medial veins, besides eleven 

 narrowly linear ones beyond the latter, and a number of small spots 

 near the border and inteiior margin. Legs banded with brown ;, 

 femora of the anterior and medial legs have three, the tibial twO' 

 bands, those of the posterior legs four bands each, the last ad-
