FIJI-NEW ZEALAND EXPEDITION 279 
Other and smaller forms were taken in the beech forest at 
Gollins Valley and under moss at the roots of trees in Kauri Gully 
near Auckland. 
In the order Dermaptera the family Forficulide is represented 
by a few forms among which is the common earwig, Anisolabis 
littorea; especially fine and large examples were taken from de- 
eayed logs at Helensville. At Gannet Island, in Cowe’s Bay, all 
stages were abundant in debris under the nests of the New Zealand 
gannet (Sula serrator). No doubt the insects perform a valuable 
service so far as the birds are concerned, in the removal of waste 
and decaying materials. 
Of the Neuroptera (nerve-winged insects), about eighty species 
are described from the Dominion. One of the entomological 
problems still awaiting investigation there, is the value of the 
aquatic insect fauna as fish food; and among these aquatic forms 
the larvae of Neuroptera as well as of Trichoptera (caddis-flies) 
and Ephemerida (may-flies) make up a considerable proportion. 
The proportionately small number of true bugs (Hemiptera) 
described from the Colony is striking; exclusive of the aphids, 
scales and psyllids, slightly over one hundred species have been 
recorded. Only nine species of stink-bugs (Pentatomoidea) are 
included in this list. One of the largest and gaudiest of these is 
the greenish Australian form (Glaucias amyoti) an example of 
which I took in Kauri Gully. It is closely allied to the cosmo- 
politan southern green plant bug (Nezara viridula) which also 
occurs in the Colony. 
One of the commonest New Zealand plant bugs (Rhopalimorpha 
obscura) is included in this group. It is an elongate linear species 
something like our Mecidea longula and can be recognized by the 
pale, mid-dorsal line. I found examples of this form hibernating 
in the grass at Wilton’s Bush. 
Of the Homoptera, the family Cicadide is one of the largest, 
containing thirteen forms, all of which are included in a single 
genus. The Cicadellide (leaf-hoppers) and the Fulgoride 
(plant-hoppers) are represented by fifteen species each. There 
are no endemic plant-lice (Aphidide) but about twenty forms 
have been introduced. 
Apparently much remains to be done in making known the 
hemipterous fauna of the islands and at the present time the 
frequent papers of Mr. J. G. Myers, of the Department of Agri- 
culture, are of much value in this connection.
