and noticing where they hover for a longer time than usual. 

 During the bright sunshine the male hutleri is seldom ever 

 seen at rest, and appears to fly backwards and forwards 

 along well-defined routes within certain natural boundaries. 

 This ' trade-route ' habit is specially characteristic of E. pluio 

 also." 



In addition to the endemic butterflies of New Zealand, 

 several wanderers from other regions have occasionally been 

 found within its limits. Writing as long ago as 1855, the 

 Rev. Richard Taylor, in his very interesting work " Te Ika 

 a Maui," mentions " a fine large butterfly, closely resembling 

 the English Purple Emperor," as being found in the Middle 

 (South) Island; and in the second edition of the book, pub- 

 lished in 1870, is a tolerable coloured figure of the male of 

 Hypolimnas holina L. under the Cramerian name of Diadema 

 auge. This butterfly has been taken not unfrequently in 

 recent years, and the large size and fine colouring of the 

 specimens, notably of the female figured by Mr. Hudson in 

 " New Zealand Moths and Butterflies," would appear to point 

 to North Australia as their place of origin. Limnas cliry- 

 sipjyus L., Catopsilia catilla Cram., and an unidentified species 

 of Euploea are exceedingly rare visitors, also in all prob- 

 ability from Australia. More difficult of explanation is the 

 undoubted occurrence, at Wellington in 1881,* and at Orepuki, 

 at the south extremity of the South Island in 1903,t of several 

 specimens of our Pyrameis alalania, whose nearest station, to 

 which it has found its way from North America, is in the 

 Hawaiian Islands, at least 4000 miles distant from New 

 Zealand. Even more inexplicable is the reported capture of 

 Aglais urticae at Wellington, at the same time as that of 

 P. atalanta, by Mr. T. Kirk; and I understand that even 

 our Pieris rapae has on one occasion been observed at this 

 port, having almost certainly been brought thither by chance 

 in one of its early stages. 



The powerful flight and wandering propensities of the 



Sphingidae have carried certain species of the family to some 



of the most remote oceanic islands, but only two have been 



observed in New Zealand. These are Herse convolvuli L.,
