New or Little Known Australasian Cicadas 
75 
Var. c. cutora (Walk.), {Cicada), 1850, List. Horn. Brit. 
Mus., p. 172. 
Synonym . — Melampsalta muta var. subalpina Myers (nec Hud- 
son), 1921, Trans. N. Z. Inst., vol. 53, p. 257. (From 
Kermadec Islands). 
Just as subalpina connects cutora with var. muta, so cutora 
shows that ochrina is almost certainly derived from muta, though 
the result is sufficiently distinct to merit specific rank. Super- 
ficially cutora is more like ochrina than like muta, but the series 
of transitional forms between the latter and cutora is complete, 
while intermediates in any sense between cutora and ochrina 
{muta Myers, 1921, nec Fabr.) have not been found. 
In 1921 (p. 244) I wrote, “It is interesting to note that this 
[muta Fabr.] is the only species not endemic. Goding and 
Froggatt (‘Monograph of Australian Cicadidse’) record it from 
Adelaide and Victoria.” We know now that this cicada is 
entirely confined to New Zealand. No authentic foreign spe- 
cimen is known. Ashton (1912, p. 25) remarks that M. angusta 
God. and Frogg. nec Walk, is a synonym of M. binotata God. and 
Frogg. Their angusta is thus the male and their binotata the 
female of a species quite distinct from angusta Walk, which is a 
synonym of the Maorian M. muta (Fabr.). 
In conclusion I should like to thank all the collectors men- 
tioned in these pages for giving me the opportunity of studying 
their material.
