PLATE VIII. 
The formation of the head and abdomen of the species on this Plate is quite 
distinct from that of any of the species previously noticed ; the former is pyra- 
midical, ending- with two strong spines, having also smaller ones on the sides; 
the latter has the fifth, sixth, and seventh joints dilated, more especially the 
middle one. The first is Hopes dilated-bodied Spectre, or Extatosoma Hopii, 
Sp. 1, the wings of which are of a blackish colour, with interrupted spotted 
whitish hands, while the costal area is green with transverse undulated black¬ 
ish bands; the tegmina are also green, and very much ridged ; the mesothorax 
short, narrow, but widening behind, with two spines situated before; the 
abdomen is narrow, of a brownish green, with the tip turned up ; the legs are 
very much dilated throughout, green with blackish transverse narrow bands ; 
the fore thighs are trigonal. 
The second is the MacLeays dilated-bodied Spectre, or Extatosoma tiaratum, 
Sp. 2. Its general colour is brownish green, but it is much thicker in pro¬ 
portion than the last; the abdomen has rows of laminae on the upper surface, 
which are dentated and of a dark brownish black. It is also armed at the 
tip with a strong, sharp, curved, black claw; the prothorax as well as me¬ 
sothorax are spined, the latter, which is somewhat triangular, only on the fore 
part; the tegmina and wings are rudimental; the legs are very much 
dilated, the thigh and shank trigonal, but the margins of the dilatation den¬ 
tated ; the first joint of the fore feet is dilated, and erect. 
Whether this insect be the pupa of another species, or the female of the pre¬ 
ceding one, is matter of great doubt; but it will be seen that I have considered 
it as the former. 
These curious insects are exceedingly rare, and are in the collection of the 
Rev. F. T. Hope. The latter species was first described by W. S. MacLeay, 
Esq., in Captain King’s Voyages, and Mr. Cunningham has kindly informed 
me, that “ they are found on the sapling 1 gum-trees in the neighbouihood of 
Paramatta.”
