with any I have descriptions of; but not having the male 
(perhaps akin to P. Kraussiana, Sauss.), the creation of a 
new genus appeared inadvisable. In the form and coloura- 
tion of elytra and wings it seems to approximate the Afri- 
can genus Danuria. 
ACRIDIDÆ. 
CORYPHISTES CYANOPTEROIDES, sp. nov., 2 (male and female). 
Resembles C. cyanopterus, Charp., but is darker and lar- 
ger; dull brownish-grey. Fastigium verv prominent, nearly 
parallel-sided, apex abruptly rounded. Eyes large, dark 
reddish-brown. Antenne ensiform, joints gradually dim- 
mishing in width from the third. ^ Ocelli inconspicuous, 
brown. Head with a fine medial ridge from near the apex 
of the fastigium, and continued to the hind margin of the 
pronotum: dark lateral  parallel-sided bands, bordered 
above narrowly white, from the inferior part of the eyes, and 
continued to the hind margin of the pronotum, the space 
between the bands marbled with black. Elytra pale brown, 
veins much darker, a few blackish streaks adjoining the base 
of the humeral and near the middle of the anal vein; 
transverse veinlets very numerous, mostly pale, but bor- 
dered mostly and capriciously deep black or brown. Wings 
with costal area smoky brown (mas.), or blackish (fem.), 
veins and veinlets much darker; remainder much paler, 
basal and anal part pale blue. Fore and middle legs slen- 
der, body colour: hind femora strong, base not very tumid, 
unarmed, inner side wholly black (mas.), or more or less 
purplish (fem.); hind tibie pale greyish externally, remain- 
der rosy-purplish; with two rows of ten spines above, the 
external ones black and much the larger. Abdomen grey 
or brown, banded dark brown or blackish (mas. and fem.) ; 
cerci conical, very short. 
Length of body, 45-47 mm. 
Length of antenne, 14-15 mm. 
Length of pronotum, 10-12 mm. 
Length of elytra, 48-50 mm. 
Length of hind femora, 21-22 mm. 
Length of hind tibiæ, 18 mm. 
This species is widely distributed in South Australia, and 
has been usually included under Charpentier's name, C. cyan- 
opterus. From this species it differs by the much more pro- 
minent and angular fastigium, general colouration, and 
other characters. It inhabits forests and woods sparingly, 
and is slow to take to flight. Its colour appears to ke 
highly protective, inasmuch as it agrees more or less per- 
fectly with the tints of the trunks of trees, etc., upon which 
it rests, or settles when disturbed.
