ever, of the same shape as in M. muta, and it may be a form of that species.

V. MELAMPSALTA SCUTELLARIS, Walker.

Cicada scutellaris, Walker, List Homopt. Ins. B. M., i., p. 150, n. 88 (1850).

Cicada arche, Walker, l.c., p. 195, n. 146 (1850).

Cicada tristis, Hudson, Trans. N.Z. Inst., xxiii., p. 52 (1891).

The type of scutellaris, Walker, is a small male in fair condition, collected by Earl," but without exact locality, in which the dark markings of the mesothorax are almost obliterated. The type of arche is a specimen bleached almost beyond recognition. M. scutellaris appears to be a variable species, and in some of its forms it approaches M. muta. It may, however, easily be distinguished from M. muta by the eighth apical cell of the tegmina, which is fully twice as long as broad, and in M. muta not much longer than broad.

VI. MELAMPSALTA NERVOSA, Walker.

Cicada nervosa, Walker, List Homopt. Ins. B. M., i., p. 213, n. 166 (1850).

This species has always reddish markings, and does not vary much. The types were presented by Dr. Sinclair, and were without locality; but there are others in the Museum labelled "Auckland.'

VII. MELAMPSALTA MANGU, B. White. Melampsalta mangu, Buchanan White, Ent. Mo. Mag., xv., p. 214 (1879).

This species is referred to M. nervosa by Mr. Distant; but I am not convinced of the identity of the two insects. Dr. White writes, "Four specimens from Mr. Wakefield, labelled 'On rocks at Porter's Pass, Canterbury, about 3,500ft.'" It may be identical with the following species, but I doubt it.

VIII. MELAMPSALTA CASSIOPE, Hudson. Cicada cassiope, Hudson, Trans. N.Z. Inst., xxiii., p. 54 (1891).

Mr. Distant has referred this species to M. nervosa, under which name I have received a specimen from Mr. Hudson; it is, however, perfectly distinct. It is, however, probably identical with an insect noticed by Dr. Buchanan White at the end of his account of M. mangu: "I have another species much resembling M. mangu, but larger, and altogether black."

IX. MELAMPSALTA IOLANTHE, Hudson.

Cicada iolanthe, Hudson, Trans. N.Z. Inst., xxiii., p. 53 (1891); Man. N.Z. Ins., p. 119, pl. 20, figs. 3, 3a, 3b (1892).

If this form is constant, it appears to be quite distinct from any of the foregoing species.

In addition to the foregoing species, Dr. Buchanan White enumerates M. telxiope, Walker (= duplex, Walker = arche, Walker). The types of telxiope and duplex, which appear to be synonymous, are from Australia, and I regard the bleached C. arche as certainly referable to M. scutellaris.

I cannot tell, without working out the great genus Melampsalta, which I have not time to undertake at present, whether any of the New Zealand species are identical with some of those described by Walker or others, under other names, from Australia, Tasmania, or unrecorded localities. Some of the New Zealand species appear to be very variable; and there must be many still undiscovered. It would be desirable for resident entomologists to try to obtain a series of the species occurring in different localities, in order to work out this small but interesting branch of the New Zealand fauna exhaustively.

From Australia (including Tasmania) about eighty Cicadida are at present recorded, belonging to the following genera:

*Thopha, Amyot (four species).
*Cyclochila, Amyot (one species).
Dundubia, Amyot (one species).
Henicopsaltria, Stäl (two species).
*Macrotristria, Stäl (one species).
Chremistica, Stäl (four species).

*Psaltoda, Stäl (nine species).
Huechys, Amyot (one species).
Tibicina, Amyot (nine species).

Abroma, Stäl (two species).

*Cyrtosoma, Westw. (two species).
*Chlorocysta, Westw. (two species).

*Tettigareta, White (two species).

Melampsalta, Amyot (thirty-seven species).

It is true that the cicad fauna of New Zealand is very much poorer than that of Australia, and that some of the genera above enumerated are tropical or subtropical forms; but both countries are very imperfectly explored at presentit can hardly be supposed that when Australia has fourteen genera-eight of which (indicated by an asterisk) are peculiar to the country-and eighty-three species, New Zealand has only one genus, represented by eight species in all.

At any

rate, I expect to find several species of Tibicina, resembling Melampsalta, but with two separate nervures rising from the end of the basal cell, instead of one nervure bifurcating immediately, as in Melampsalta. If special attention is given to the subject by collectors, I have little doubt that several new species, and even genera, might easily be added to the New Zealand list.
