length of first.  Pronotal carinae curved, diverging, not reaching hind- 
margin. Hind basitarsus slightly longer than other two together; spur 
as long as basitarsus, broad, laminate, about twenty small black teeth on 
hind-margin. 
Fic. 1.—Anal segment and aedeagus of Nilaparvata myersi.

Fig. 2.—Anal segment and aedeagus of Delphacodes tasmani. 
Fic. 2a.—Left genital style of same. 
Light brown; darker between carinae of face, clypeus and genae, and 
on pleura of thorax ; legs lighter brown, abdomen dark. Median carinae 
of thorax and the base of commissure light. Tegmina hyaline, a sma 
dark mark on hind-margin at apex of claval vein, veins slightly darker than

escribed from one male (holotype) and one female (allotype) from 
Waikanae (J. G. Myers, 4th February, 1921, No. 125). "There is à second 
female (paratype) from Bull Mound, Tararua Range, 3,300 ft. elevation 
(J. G. Myers, 13th February, 1921). Another female from Waikanae 
may be immature; it is very much lighter in colour. All these deposited 
in the Dominion Museum, Wellington. 
Beside the above two species, one other species of Delphacodes is known 
from New Zealand (D. meridianalis Muir*), which is closely related to 
. tasmani. If they should prove to be the same species it will be of 
interest, as it will show a distinct difference of genitalia in the brachypterous 
and macropterous forms.
