The following is a key to the species : —

Brunner's figure shows spines on the middle femora, al- 

 though no mention is made of them in the text. 



Pachyrhamma fascifer (page 232). 



In the third line of the description, for " fore tibiae " read 

 " middle tibiae." 



Pleioplectron diversum (page 235). 



I have received from Mr. W. F. Howlett, of Makaretu, 

 Hawke's Bay, a male specimen of this species, which shows 

 that it cannot be kept in Pleioplectron, as the supra-anal and 

 subgenital plates are very different, but must be placed in a 

 new genus, for which I propose the name " Miotopus." 



MiOTOPUS, gen. nov. 



Fore and middle femora with two short apical spines, those 

 on the middle femora longer. Middle tibiae armed with spines 

 on the upper surface. Supra-anal plate of the male trans- 

 verse, the apex truncated and without any point ; the cerci 

 rather long and slender. Subgenital plate of the male longer 

 than broad, rounded at the apex, the styles very short and 

 situated near the apex. The rest as in Pleioplectron.

p. 235. 



Male. — The antennae are thicker than in the female. The 

 middle tibiae have two or three spines on the upper surface. 

 Length, 20 mm. ; of pronotum, 5 mm. ; of thorax, 9 mm. ; of 

 abdomen, 10 mm.; of fore tibia, 10 mm.; of hind tibia, 

 18 mm. ; of hind femur, 16 mm. Width of mesonotum, 5 mm. 



Locality. — Makaretu, Hawke's Bay (W. F. Howlett). 



Macropathus ed^vardsii (page 240). 



Mr. Scudder has kindly re-examined the type of this species 

 for me, and finds that it does not agree with Brunner's descrip- 

 tion of what he thought to be H. edivardsii, nor does it belong 

 to Macropathus, as I supposed it might do, but to Pleioplectron. 

 He informs me that " the fore femora have an apical spine on 

 the outer side only, the middle femora on both sides, and the
