Mr. G. R. Gray's new Species of Phasmata. 



X. Descriptions of several Species of Australian Phas- 

 mata. By George Robert Gray, Esq., M.E.S. France 

 and London. 



[Read February 3, 1834.] 



In my published Monograph of the Australian species of the genus 

 Phasma, I have described sixteen species, thirteen of which are for 

 the first time noticed ; since its publication several new species have 

 reached me, and I am induced to lay them before the Society for 

 the purpose of extending the monograph. 



The species to which I first wish to call your attention belong 

 to the second section formed by me under the denomination of 

 Diura. 



5*.' Phasma (Diura) Goliath. 



Viride, mesothorace scabriusculo ; alis hyalinis, glaucis ; area 

 costali tegminibusque supra viridibus, maculis lineisque rubro- 

 albis, subtus sanguineis ; foliolis brevibus in medio carinatis. 



Long. Corp. 8 unc. 6 lin. Exp. alar. 8 unc. (Anten. mutilatis.) 



In size it approaches Ph. Titan, but differs in having much longer 

 and broader wings than are usual in this section, which, when closely 

 applied, cover two thirds of the abdomen. The leaflets are rather 

 short, keeled down their length so as to form a V reversed. The 

 colour of the head and prothorax is pinkish white ; that of the 

 mesothorax is yellow, with a bluish green line along the centre. 

 The abdomen is green, with the joints yellow, and margined on 

 each side with black. The fore legs are rather short; the two 

 posterior pairs are of moderate length, and strongly spined on their 

 inner margin, the spines being somewhat depressed. 



The specimen from which the above description is taken is in the 

 collection of New Holland insects belonging to Mrs. Dunn, who 

 is uncertain from what part of the country it was obtained. Mr. 

 John Curtis also possesses a specimen ; but both individuals have 

 lost their antennae. 



6*. Phasma (Diura) Briareus. 



Brunneum, mesothorace vix scabro ; foliolis brevissimis, latis ; 



pedibus brevioribus, posticis quatuor spinosis. 

 Long. corp. 5 unc. 9 lin. Exp. alar. 2 unc. 5 Hn. 

 This insect is aUied in several respects to Ph. Chronus. The 

 description is taken from a female, the other sex at present being 



' These numbers refer to the corresponding ones in my Monograph of the 

 Australian species of this genns.
