Habitat.—Wirrabara Forest Reserve, South Australia (Coll 
S.A. Museum). 
The specimen described was captured and presented by A. 
Molineux, Esq., F.L.S., the active Secretary of the Bureau of 
Agriculture, and is dedicated to him as a slight acknowledgment 
of his unobtrusive and disinterested zeal in promoting natural 
history for many years. The species is distinct from all others 
by the intense dark colour of the terminal abdominal segments, 
the ninth approaching Brunner’s type “A,” but the subgenital 
lamina presents quite a different aspect. The external darkly! 
tipped spines of the hind femora are much larger than the 
internal, the more or less red-coloured ones of the hind tibiz are 
almost equal in size. 
PARAGRYLLACRIS, Gerstaecker (Brunner, Mon., 369, fig. 44). 
Habits of Gryllacris, but differing in the form of the sub- 
genital lamina of the male, the latter possessing no articulately 
inserted styles, and the hind femora (in the typical form) being 
armed with five to seven minute spinelets. 
Fastigium of vertex usually twice as wide as the first antennal 
joint. Elytra ample, obtusely acuminate, never obtuse, veins 
and veinlets more or less infuscate. Wings subhyaline, never 
striped. Hind femora below with rather stout spines, often 
distant or absent. Fore and middle tibiz below with five pairs 
of spines. Hind tibie above with five spines usually on each 
side. Abdomen of male with the eighth dorsal segment normal, 
the ninth more or less hood-like, the hindmargin truncate or
