PLATE IV. 
The magnitude of the Titan tailed Spectre, or Diura Titan, Sp. 5, is greater 
than that of any of its congeners ; and the Rev. W. Kirby, in his valuable “ In- p iic 
troduction to Entomology,” has noted it as the largest of all the Orthopterous 
insects which are at present known. (The figure in the Plate represents it 
two inches short of its natural size.) The general colour of the wings is 
blackish brown, but irregularly spotted and banded with white; the costal 
area is of a greenish black irregularly spotted with testaceous, and has the 
base red. The tegmina are similar to the last in colour and markings, but 
with a white spot near the centre of each ; the head and prothorax are of a 
greyish colour; the former has three distinct stemmata in front; the meso- 
thorax is reddish, but with scattered sharp tubercles ; the abdomen is orange, 
with the tip and leaflets of a gray colour,—the latter rather short in pro¬ 
portion to those which some species possess, and are quite differently formed 
from the others, being trigonal and dentated; the legs are also short and 
very much dentated, but the fore ones are trilateral. 
The pupa has the body similar in colour to the older stage, but it has the 
appearance of being spotted ; the rudimental wings are decidedly spotted with 
white. 
This splendid species, Mr. Cunningham informs me, is found on shrubs in 
the scrubby parts of the Colony, in the month of December ; it is very soli¬ 
tary in its habits, and is locally termed “Walking Straw, or Animated Stick.”
