HuTTON. — Ow the Phasmidse of New Zealand. 51 



Mr. H. Suter submitted to me for examination a large col- 

 lection of these insects which he had obtained fi'om tlie Great 

 Barrier Island, and he has very kindly given to the Canter- 

 bury Museum a complete set of the species it contained. This 

 collection, coming from the north, from whence all the earlier- 

 described species came, has enabled me to identify all but one 

 of the species described by Mr. Westwood, and all but two of 

 those described by the Rev. W. Colenso ; and I am therefore, 

 thanks to the aid of Mr. Suter, in a position to make what I 

 believe to be an accurate list of the known species. 



I find that, having had southern specimens only to examine, 

 I made some wrong identifications in my last paper. I there- 

 fore now withdraw all the localities given in it, and substitute 

 those in the present paper. 



I feel rather doubtful about reintroducing the genus Acan- 

 thoderus, of Gray, as it is not defined either by Stal or by 

 Brunner. Gray's type — A. spinosus, from Western Australia 

 — was in the Hope collection, and may have been seen by 

 Westwood, who placed A. spiaiger and A. horridus next to 

 it, followed by A. prasimis. But the generic characters say 

 that the mesothorax is iiearly as long as the metathorax, 

 which is not the case in A. horridus {= A. spiaigur), but is 

 true ior A. 2) ''(isiiius. I therefore suppose that .4. pr.ism^is is 

 congeneric with A. spinosus, but the point can only be settled 

 by a comparison of the tvvo species. The Acaathoderics of 

 Stal, in his " Recensio Orthopterorum " (p. 49) — given as 

 Acanthoderus (Westw.) — is, as he says, very different, and 

 belongs to a different family. But Stal had no right thus to 

 shift Gray's name. 



As references to descriptions and figures of the species are 

 given in my last paper, I have not thought it necessary to 

 repeat them here. 



All the New Zealand Phasmidcs belong to the tribe 

 Glihiinnides, as defined by Brunner de Wattenwyl in his 

 "Revision du Systeme des Orthopteres," 1892. The an- 

 tennae in the young are proportionately shorter in this tribe 

 than in the adult, but they have the full number of joints. 



Tribe CLITUMNIDES, Brunner (1892). 



Antennae shorter (or not much longer) than the anterior 

 femora, the joints distinct and not more than 28. Median 

 segment of the metanotum short. Apterous. Tibiae carinated 

 below to the apex, and without any apical areola. 



In all the New Zealand species the suture between the 

 median segment and the metanotum proper is obliterated, but 

 its position is generally marked by a spine, or a pair of spines ; 

 or, in Clitarchus, by a black spot.
