of a habit which must have remained dormant or latent 

 through many generations. It is well known that physical 

 characters may remain latent for an unknown number of 

 generations, but this is, I believe, the most remarkable case 

 yet recorded of latent psychological characters. 



CoKRECTioNS IN THE Plates (page 241). 

 Plate XII. 



Fig. 46. The sounding-organs are not shown in the figure. 

 Fig. 5b. Should be " Onosandms focalis, side view, showing sounding- 

 organs." 

 Fig. 5c. Should be omitted. 

 Fig. 5d. Should be " Onosandms focalis, sternum." 



Plate XIII. 



Fig. 13a. Should end in a point, not in a slit. The slit was intended to 



represent a keel. 

 Fig. 15. Should be " Pleioplectron hudsoni, supra-anal plate of male." 



Mr. W. F. Kirby, of the British Museum, has kindly 

 looked over Walker's types, and sends me the following 

 notes : — 



Deinacrida heteracantha, White. — Perhaps distinct from 

 D. gigantea. 



Hemideina thoracica, White. — The type has distictly four 

 spines in each row of the hind tibiae. H. capitolina, H.figurata, 

 H. producta, H. abbreviata, and H. tibialis all appear to 

 belong to H. thoracica. 



Hemideina armiger, Colenso. — The same as D. thoracica, 

 of Brunner. 



Onosandrus lanceolatus, Walker (Ceuthophihis). — Appears 

 to be a dark uniformly coloured specimen of 0. ])allitarsis. 



Pachyrhamma fascifer, Walker. — This appears to be P. 

 speluncce. 



Pachyrhamma altus, Walker. — Seems to agree with P. 

 novce-zealandice. 



Macropathus species, from Auckland. — Larger than M. 

 filifer, and with much more numerous and conspicuous teeth 

 on the hind femora beneath.
