PLATE VI. 
The splendid colour of the wings of this species distinguishes it from the 
other species ; it is named J^iolet-U/inged tailed Spectre, or Diura violascens, 
Sp. 9. The costal area is yellowish green tinged with brown; the anterior 
margin bright yellow, with the outer ridge white ; the tegmina are similar 
to the latter in colour and markings: but the most remarkable character 
which this insect possesses, is the immense strength and thickness of the 
hind thighs, though of a moderate length in comparison with the size of the 
insect; they are also armed with three strong, long, black spines, situated 
beneath, the one near the base is smaller than the other two ; they are also 
strongly dentated, with elevated longitudinal lines on the upper surface, 
and are of a reddish yellow ; the head is small without any stemmata; the 
inesothorax is rather long, nari'ow, but wider at the base, and is brownish 
yellow, covered with minute tubercles ; the abdomen is reddish violet, with 
the tip green, but the leaflets are reddish violet; the four fore-legs are green, 
with the thighs of the intermediate pair dentated. 
The figure is taken from a specimen in the collection of the British Museum, 
and I believe xvas brought by Mr. Hunter ; it had been previously described by 
Dr. Leach in his “ Zoological Miscellany.” 
The second figure is the Typhceus tailed Spectre, or Diura Typhaeus, Sp. 8 ; 
the tegmina of which are brownish green, with a red longitudinal line down the 
centre, their fore-half white, with the outer ridge pale blue; the wings are 
yellow, with their summit dusky ; the costal area brownish green tinged with 
red; the fore-margin and near the base white, with the outer ridge pale blue, 
but the base is purplish ; the head, prothorax, mesothorax and the legs, are 
red; the mesothorax is covered with minute tubercles; the four hind legs 
are strongly dentated ; the abdomen is yellowish green tinged with red; the 
leaflets rather short, and red. 
The British Museum contains the fine specimen from which the drawing was 
taken.
