PHASMIDjE. PALOPHUS. 



£»] 



Deceived by the locality of Australia given to this species 

 by Mr. G. R. Gray, as well as by his short, incomplete, and 

 not quite accurate description, I had regarded the male in 

 the British Museum Collection as a distinct species ; but 

 an examination of the typical specimen in the Hopeian Col- 

 lection at Oxford has convinced me that it is identical with 

 it. Mr. Hope's specimen is also a male, and it has no 

 locality attached to it ; so that the locality of Australia 

 given to it must have been conjectural. Both sexes are 

 contained in the Royal Museum at Berlin, and the female 

 is also in the Leyden Museum. 



The following is Mr. G. R. Gray's description of this 

 species : — " Brunneus, cornubus inter oculos duobus longis, 

 compressis ; thorace rugoso ; alis brunneis, margine supe- 

 riori nigrescentibus, basi nigra, nervis obscuris ct albo ma- 

 culatis ; tegminibus in medio paulum elevatis ; pedibus 

 longis gracilibus simplicibus hirsutis." 



The male is very slender, with a disproportionately long 

 abdomen, the hind legs not extending beyond its extremity, 

 and with a comparatively short mesothorax. It is ashy- 

 coloured, with the abdomen brown, and the legs obscurely 

 fasciated. The head and anterior parts of the thorax are 

 granulated ; the former with a large double setose horn, 

 porrected in front, arising between the eyes. The ocelli 

 are large ; the anterior placed in front of the frontal horns, 

 and the lateral ones at their sides. The antennse are up- 

 wards of 2\ inches in length, finely setose ; they consist in 

 the British Museum specimen of thirty-eight joints, but 

 some at the tip are probably broken off ; the joints are elon- 

 gated, the base of each pale, and the apex darker. There is 

 a small spine on each side of the head between the eyes and 

 mandibles. The mesothorax is not longer than the head 

 and prothorax united ; it is slender and subcylindrical. The 

 abdomen is very long ; the three terminal joints short, the 

 last emarginate at the tip, exposing the ends of the short 

 anal styles ; the three terminal ventral segments are ab- 

 breviated, the last not extending beyond the middle of the 

 eighth dorsal segment, it is moderately swollen. The teg- 

 mina are elongate-ovate, with a strongly elevated tubercle 

 between the base and the middle ; the fore margin is 

 whitish, with a black oblong patch. The wings are large ; 

 the costal portion pale brownish-buff, with a dark brown 

 spot at the base ; the hind portion brown, with pale buff 

 spots irregular in size, but mostly circular and arranged on 

 the longitudinal veins. The legs are slender and setose ; 

 the anterior pair considerably elongated ; the fore femora 

 with a small spine on the upper edge in the middle ; the 

 middle and hind femora with a small spine near the base 

 beneath, and a little further removed from the base, above ; 

 all the tibire have two small spines on the outer edge, one 



before and the other beyond the middle ; the tarsi are 

 short, with the basal joint of the fore legs rather dilated. 



The female has the wings half the length of the abdo- 

 men. The mesothorax is proportionably longer and much 

 wider than in the male, with two pairs of tubercles on its 

 upper surface. The third, fourth and fifth segments of 

 the abdomen are produced on the hind dorsal margin into 

 two small pointed lobes ; the eighth segment is very short ; 

 the ninth longer, truncate at its extremity ; and the oper- 

 culum does not extend beyond the middle of the ninth 

 dorsal segment.

Very long and slender, subrugose, brown, varied with 

 ashy. Head subquadrate, armed above with several small 

 spines, and with two small rounded tubercles near the hind 

 margin ; the front of the head armed with two elongated 

 compressed laminae, porrected obliquely, the tips emargi- 

 nate. Ocelli wanting. The pro- and mesonotums are 

 opake ashy-brown, the latter with several oblong small 

 black spots. The abdomen is very long ; the fourth seg- 

 ment with two small oblong lobes on its upper side at the 

 extremity ; the seventh segment half the length of the sixth, 

 the eighth half the length of the seventh, and the ninth 

 as long as the seventh, the ninth truncate at its extremity ; 

 the anal styles short and obtuse. The operculum extends 

 to about one-third of the length of the ninth dorsal seg- 

 ment ; the posterior half finely keeled ; with a small
