transverse furrow in the middle. Mesonotum and nietanotum 
similar to preceding; also abdomen. Tegmina reddish- brown, 
costa not whitish, but a whitish, oblique streak indicated ; apex 
rounded. Wings rather short, obtusely rounded : costal area 
reddish-brown, with indistinct dark markings along the costal 
margin : membranous area almost colourless ; veins alter- 
nately pale and dark : veinlets narrowly bordered witii black- 
ish, but no other spots or blotches present. Legs long and 
slender, with minute, dii4ant spihelets along the ridges of 
femora and tibise. 
Length of body without cerci, 73 mm. 
Length of head, 4 mm. ; wictth, 2 '5 mm. 
Length of antennae, 22 mm. 
Length of pronotum, 3 mm. ; width, 2 mm. 
Length of mesonotum, 10 mm.: width, 1'5 mm. 
Length of metanotum, 5 mm. ; width, 2 '3 mm. 
Length of abdomen, 51 mm. : width, 1'3 mm. 
Length of tegmina, 8 mm, ; width, 3 mm. 
Length of wing, 38 mm. ; width, Iti mm. 
Length of cerci, 5 mm. 
Although agreeing in size and colour patterns of the 
wings with Westwood's fig. 1 of Plate xxxv. (Cat. Phasm., 
B.M.), the specimen differs much in the minuteness and 
paucity of the spinelets of the femora and tibiae of the legs, 
etc. The ocilli appear also to be practically replaced by mere 
shalljow depressions. There are no other specimens in the 
S.A. Museum collection resembling either of the above. There 
is in the collection a female from Lake Aroona (N.W. from 
Port Augusta), and also a nymph of one, which appear to 
belong to the described male in general aspect, contour, and 
colour of wings, etc. Both were collected in December, 1900, 
by Mr. A. Loveday, and are differing in being larger. 
Necroscia bella, spec. nov. 
Male. Greenish to reddish- brown ; very slender. Head 
above rounded, minutely and distantly tuberculate, occiput 
anteriorly with a deep oval impression, median line indis- 
tinct : sides flat. Antennae not much longer than the anterior 
femora, finely and densely hairy. Pronotum narrower and 
much shorter than the head, with a slight longitudinal and 
a promiscuous transverse carina in the middle. Mesonotum 
scabrous, nearly twice as long as the two preceding together, 
and attenuated towards the middle from both ends. Meta- 
notum stout and the widest part of the body. Abdomen 
slender, gradually attenuated towards and inclusive of seventh 
joint, remainder moderately tumid. Subgenital lamina half 
the length of joint, apex emarginate. Cerci short, ovate.
