ENTOMOLOGY OF AUSTRALIA. 
PLATE III. 
The form of the Yellow-winged Spectre, or Trigonoderus Children!!, Sp. 3, 
differs much from the Pink-winged species in regard to its legs, for they are 
rather longer ; the four posterior ones have their thighs dilated outwardly and 
serrated, but all are of a glaucous colour ; the mesothorax is somewhat trian¬ 
gular in form, and keeled down the centre, with the sides sloping, and the outer 
margins serrated ; the wings hyaline, tinged with yellow ; the costal area is 
much broader near the centre than at the tip, and is of a dark green, with the 
part near the base yellow, while the base itself is violet; the tegmina are of a 
dark green, ridged in the centre ; the abdomen is yellow, with the margin on 
the sides, the hypopygium or last ventral segment, and the leaflets dark green; 
the latter are very short. 
This figure was taken from a specimen in the collection of J. G. Children, 
Esq., which was brought home by Mr. Cunningham, ’who informs me that they 
are found in the same place as the Pink-winged species (PI. II. fig. 1.). The 
British Museum also contains two specimens of this fine insect.

The second insect represented in the Plate is the Short-horned dirty Walk¬ 
ing-stick, or Bacillus squalidus, Sp. 16, and differs very much in form from the 
others in this work; the colour is of a dark sepia brown, with some white, 
and has much the appearance of being scaly ; the thorax and abdomen are 
keeled down their centre. The latter is short with the base depressed, while 
the tip is compressed ; the legs are rather short, with elevated lines: but the 
four posterior thighs have three teeth, placed at equal distances on the upper 
sides. 
This curious insect is in the possession of the Rev. F. T. Hope.
