the head, with some longitudinal furrows, terminated by a 
transverse carina near hind margin. Mesonotum cylindrical, 
gradually tapering to near base of elytra, then rapidly ex- 
panding to more than double between median legs, thickly 
beset with many small interspersed and some large spines. 
Metanotum stout, glabrous, with three pairs of short, oblique, 
white streaks underneath. Legs very long and slender, all 
ridges with small, distant spinelets, except those of the anterior 
tibiae and of the tarsi. Tegmina short and narrow, costa and 
a short, oblique, discal streak whitish, remainder bro\v?i. 
Wings long and rather narrow ; costa with some small dark 
spots from near middle to apex : veins and veinlets from pale 
to dark brown, some of the former interruptedly black to- 
wards margin ; veinlets bordered with blackish-brown ; outer 
margin broadly suffused with dull blackish, likewise the costal 
part of the membranous disc, with irregular blotches, the 
dark markings separated by translucent areas. Abdomen 
very slender throughout ; sexual organs, including respective 
joint and lamina, also anal joints, very short and tumid. 
Cerci broad, ovate, subacute, nearly as long as the preceding 
three joints together.

The species is comparable with Acrophylla tesselata, 
G.R.G., from N. Australia (Westwood, Cat. Phasm. B.M., 
Plate xxxv., fig. 1), but is larger, and differs in the paucity 
of the spinulation of the legs, colouration of the wings, etc. 
Tiiere are a pair of similar insects in the collection from Cen- 
tral Australia, but appear to differ in proportions. 
Acrophylla paula, f^pec. nov. 
Male. Brown; in general aspect resembling the preced- 
ing, except size and wing form, in which it approximates '\ . 
tesselata, Westwood. Head flat, occiput, with anterioi median 
depression (obsolete ocellus) much larger and deepei than in 
preceding, and other markings different. Antenna long, 
slender, 16 (?) jointed, minutely hairy. Pronotum with
