32 Mr. R. M'Lachlan on the Neuropterous 



be a scarcity of aquatic insects both as larva? and otherwise, 

 and of those aerial insects upon which the perfect Dragonflies 

 prey. Another point strikes me; and that is the small number of 

 aphidivorous Planipennia, the chief of which (the Chrysopidse) 

 are unrepresented. Can it be that indigenous Aphides are 

 happily almost unknown there ? It may be that the ideas 

 here thrown out are based upon erroneous premises ; and if so 

 it behoves the entomologists of NeAV Zealand to set me right 

 by producing a fair sample of the insect fauna of their colony. 



The list of Trichoptera here given is scarcely more than a 

 reprint of that already published by me in the ' Journal of the 

 Linnean Society' (Zoology), vol. x. Much of the material 

 from which the entire list is compiled has been received from 

 my friend Mr. R. W. Fereday of Christchurch, and from Mr. 

 H. Edwards, who was for some time at Auckland; nor must the 

 collections formed by Dr. Sinclair, Mr. Colenso, Dr. Hooker, 

 Col. Bolton, the naturalists of the ' Novara,' &c. be forgotten. 

 No special localities are given, because many of the insects are 

 noted simply as from New Zealand without further indication. 



In the references I have indicated by an asterisk where the 

 best description of each species may be found ; and if this sign 

 occurs so frequently in connexion with my own descriptions, 

 the reader must please consider that I do not claim for them 

 any special excellence, and that it is owing to the fact that in 

 most cases no others exist.

Hagen described a wingless example from Van Diemen's 

 Land. Brauer described the winged form of what he considers 

 to be the same species from New Zealand.
