ExTATOSOMA ELONGATUM, n.sp. (Plate xxxviii.) 



$. Length from front of head to tip of body 5 inches; c? unknown. Colour 

 deep green, lightest on the wing pads; abdomen and legs mottled with dull white 

 and gTeyish spots. Fine spines on head, thorax, and abdomen reddish-brown. 

 It differs from Extatosoma tiaratum in being much more slender in form, and in 

 having the more slender leg's with very narrow arcuate flanges or ridges on the 

 femora and tibia, with small lateral flanges on the sides of the first four abdominal 

 segments, and those on the following very much reduced in size; the whole 

 surface is covered with stout spines, thickest on the under surface. The sides 

 and crown of the head thickly covered with sharp pointed spines, with two double 

 spines on the summit. The prothorax covered with similar spines with two 

 double-spined ones on the hind margin; the mesothorax bearing spines on the 

 sides, with three pairs on the dorsal surface, the first pair conical, blunt at apex, 

 with a group of two thickened spines and two single ones in front of the base 

 of the insertion of the tegmina, the metathorax with four parallel rows of smaller 

 spines on the dorsal surface. The legs with the dorsal and lateral edges toothed 

 with short mottled thorn-like spines, the coxae usually bearing shorter stout 

 conical spines, .with an odd double spine here and there. 



The fii-st three abdominal segments rounded, with a pair of double finger- 

 like spines in the centre of the back and simple spines on either side; below 

 there, standing out is a horny, arcuate, spined, flattened flange. The fifth and 

 sixth segments have a pair of serrate, parallel, erect flanges in the centre of the 

 back and two stout spines; on either side is a large flattened serrate flange in a 

 line with those of the first three segments, about a third larger, and spined in 

 the same manner. The 7th abdominal segment is small, with similar but smaller 

 spines, and the side flanges are turned downwards. The 8th and 9th are small, 

 projecting above the genitalia with similar small spines, and the hind margin of 

 the anal one is fringed with spines. The ventral surface and sides of the abdo- 

 minal segments are lightly covered with slender reddish-brown spines. 



Hab. — Gosford, N.S.W. Found crawling over a brush tree; afterwai'ds kept 

 in a breeding cage for a week when she laid over 100 eggs. There is another S 

 specimen in the Macleay Museum Collections from Camden, N.S. Wales.
