In that large division the Fulgoroidea, the most largely represented family 
in New Zealand, both in species and in individuals, is the Cixiidae. At 
the present time the Fulgoroids of New Zealand are contained in seven 
amilies, eighteen genera, and twenty-nine species. Of this total the 
present extremely rudimentary knowledge of the New Zealand Homoptera 
it is safe to say that the Cixiids are the dominant Fulgoroids of this 
region. 
The object of this paper is to give an up-to-date revision of the family, 
and to deseribe new genera and species. Such a revision can be only 
I wish to express my deep gratitude to Mr. Frederick Muir, of Honolulu, 
who has helped me with keys to genera and with muc other assistance 
from his wide homopterological experience. He has also compared m

collectors who have sent me Homoptera from all parts of the Dominion. 
e genitalia were dissected and mounted in the manner recommended 
by Giffard and Muir.* The card mounts, made with the help of two cover- 
slips, and kept on the same pin with the insect, were found extremely 
convenient, and served every purpose when drawing was done with a 
camera lucida. When, however, the genitalia were microphotographed it 
was found that ordinary glass slide mounts, besides being easier to handle, 
gave much better results. 
The Cixiidae are easily collected by beating bushes and by sweeping 
herbage. More specimens from out-of-the-way localities and from islands 
. are urgently desired. They should be killed with cyanide or laurel, and 
stored dry, without pinning, and may be kept indefinitely, or sent through 
the post in pill-boxes with a little soft paper. Like all small or medium-
