Psyche 
[June 
Stradbrooke Island, is darker than most of the other members 
of this group. 
Of this list, quadricincta, nervosa, M. sp.?, with melanesiana 
and the New Zealand alpine cicada, cassiope Huds., were placed 
by Distant under the synonymy of the first-named. The name 
quadricincta is therefore to be expunged from New Zealand lists. 
Sericea , of which nervosa is a synonym, is nearest to melanesiana 
and to quadricincta. To the latter it is closer in facies and in 
width of head, but the two are distinct in opercular structure 
since sericea has no signs of the swelling so highly developed in 
quadricincta. To melanesiana it is related in opercular structure, 
the swelling being very feebly developed in the New Caledonian 
species, but the facies is different largely on account of the wider 
head of the latter. Sericea is fairly distinct from both in male 
genitalic characters. 
Needless to say, the synonymisation of cassiope with nervosa 
or with any other species of this group has no foundation in 
morphology or even in appearance. But M. viridicincta Ashton 
(1912, p. 78, pi. 7, fig. 5) from Perth, W. Australia, certainly 
belongs to this group, and judging from the description is almost 
certainly a sjmonym of quadricincta. 
The genitalia of several forms from the group under dis- 
cussion are figured. 
Mel&mpsalta melanesiana sp. n. 
cT. Head very short and very wide — wider than anterior 
part of pronotum and equal to widest part of pronotum. Meso- 
notum comparatively narrow. Abdomen long oblong, somewhat 
laterally compressed. (This compression may be due to drying, 
but related species do not dry thus). Not hairy. Seventh 
sternite long, somewhat truncate apically. Venation normal 
for the genus. Fore femora with the usual three spines beneath. 
Aedeagus as figured (4). Hind tibia with five spines not counting 
the apical ones Opercula short and well-separated with prac- 
tically no signs of the shining boss at the base. 
Color black with greenish and testaceous markings as fol- 
lows, — greenish markings. — anterior border and posterior tri-
