The general colour is rusty-brown, the surface granulato- 

 rugose, the under side of the body being opake, slightly 

 rugose, with the abdominal segments simple. The head 

 is rugose and furnished above with two large and four 

 smaller spinose leaflets, which are elevated and laterally 

 obliquely porrected, the larger ones being rounded on their 

 anterior upper margin, the crown of the head is furnished 

 moreover with two spines ; the basal joints of the antennae 

 are rugose (the terminal joints are broken off in the unique 

 specimen in the National Collection). The prothorax is 

 rugose And spined at its upper side, with two diverging 

 spines near its hind margin. The mesothorax is spined 

 along the sides, which are gradually dilated to the base of 

 the middle legs ; the anterior part bears a triangular rugose 

 space, armed with spines at the sides, and there is a central 

 longitudinal elevated line with two strong spines in the 

 centre. The metathorax is about half the length of the 

 mesothorax, considerably dilated at the sides in front of 

 the base of the hind legs, armed with two strong spines 

 near its base, and the sides also spined. The abdomen is 

 rugose above ; the extremity of the basal segments with a 

 minute compound lobe in the middle of the hind margin, 

 which becomes foliaceous and much larger in the fourth 

 and fifth segments, but gradually diminishes on the hind 

 segments. The abdomen is as wide as the mesothorax, but 

 narrowed at the base of the seventh segment. The oper- 

 culum extends beneath the whole of the seventh, eighth. 



and ninth segments, not however extending beyond the 

 latter. The femora are irregularly foliaceo-dentate, both 

 along the fore and hind edges, and the tibiae are irregu- 

 larly but widely serrated on the outer edge. The tarsi have 

 the basal joint slightly larger than the second joint.

The whole insect is opake, and considerably varied in its 

 colour from green to rusty-brown and hgliter buff; it is 

 covered with small granules or spines, and is armed with 

 numerous conical leaflets, which are denticulated at the 

 edges. The head is armed with two conical spinose lobes 

 on the crown, behind which are two erect spines. The 

 antennae are long and slender, with the tips of the joints 

 (in the basal half of the antenn*) darker- coloured than the 

 basal portion. The jirothorax is armed with two erect 

 spines in front, and four in a transverse row behind. The 

 mesothorax, in addition to the pair of large triangular spi- 

 nose leaflets, is armed with four pairs of erect sjiines. The 

 metathorax also bears a pair of smaller spinose triangular 

 leaflets, and two pairs of dorsal spines, one pair close to 

 the fore margin, and one pair beyond the middle. The 

 six basal segments of the abdomen are armed at the sides 

 with triangular spinose lobes ; and on the upper surface 

 near the base of each is a pair of small spines wide apart, 

 with a pair of large spines approximated together in the 

 middle "of the hind margin, accompanied in the third and 

 fourth segments by a spinose erect lobe ; the three terminal 

 segments are very much compressed, the eighth segment 

 being furnished above with an ovate erect serrated lobe ; 

 the ninth segment is produced in a slender plate at its ex- 

 tremity ; the operculum extending to the extremity of the 

 abdomen, but with its extremity deflexed. The legs are
