[June 
Coloration much as in female described in 1923, but on the 
whole much darker, especially on the abdomen, which is largely 
black, the tymbals pale. Seventh tergite posteriorly margined 
with olivaceous and eighth very widely with red and tipped with 
shining silver pubescence. A median longitudina dorsal line 
formed by patch of this pubescence on nearly every tergite and 
an edging to the third to eighth tergites laterally, conspicuous in 
dorsal view but less so from lateral aspect. Veins red, darker 
apically, the tegmen suffused very strongly with olive-brown. 
Axillary membranes of tegmen and of hind-wing and much of 
anal area of latter china-white. 
Dimensions in mm. (the second figure in every case is that 
of paratype female). — Length to tip of last tergite, 15.0; 15.5; 
length of head, 1.5; 1.9; width between eyes, 2.4, 2.4; ratio, 
.63; .80; length of pronotum, 2.4; 2.4; length of mesonotum, 
3.0; 3.0 length of tegmen, 15.0; 14.0; greatest width of te- 
men, 5.5; 5.4. 
Allotype, male, Otira, New Zealand, 1,700 feet, 5th January, 
1923, Iris Myers. (Series taken) 
Other material has been examined as follows — Examples 
from Mt. Cook, 2,500 feet, 8th March, 1923, R. J. Tillyard; from 
Waiau, Southland, 19th January, 1914, A. Philpott; from White 
Rock, North Canterbury, December, 1918, S. and C. Lindsay. 
All these specimens agree in being much darker than the 
types and with less suffusion in the tegmen, at least than in 
freshly caught examples. For these reasons the males from 
Waiau and from White Rock were not previously recognised as 
conspecific with the females on which the description of the 
species was based. 
A freshly caught female is less brilliant than the holotype, 
which had evidently bleached out much of the darker color, 
together with the suffusion of the tegmina. 
The song of Melampsalta camphelli . — This song is faint, 
slow and of a muted quality rather resembling that of M. scu- 
tellaris, of which it is occasionally reminiscent also in rhythmic 
structure (C) though quite distinct. The cicada was first heard 
(at Otira in January, 1923) singing when the sun was hidden by 
clouds. A long note, lasting 6 seconds, was followed by a mono-
