Meyricx.—On New Zealand Micro-Lepidoptera. 33 
A peculiar and very elegant species, not nearly allied to any other, and 
immediately recognizable by the ferruginous longitudinal streaks; it has more 
the general appearance of some of the Phycida, but it is a true Crambus, 
Two specimens taken by Mr. R. W. Fereday in March near Lake Coleridge. 
Nore.—Crambus sabulosellus, Walk., C. trivirgatus, Feld., and C. rotuellus, Feld., do 
not belong to this family at all, and are therefore not referred to above.

The Tortricina of New Zealand are less numerous than at first sight 
they appear to be, or than would be inferred from a study of authors. 
Walker described 40 species, but after the removal of synonyms, and un- 
identifiable descriptions of which the types have been lost, these are redu- 
cible to 12. Zeller has added one new species. Felder has described 9, 
out of which (excluding Pedisca mahiana, which is unknown to me, but 
perhaps not a New Zealand species) only one is new. Butler has, also, 
described 7, of which only two are new. I have previously described 9 
others, and now give descriptions of 11 additional species, which, with two 
naturalized European insects, bring up the entire number to only 38. 
I have been led by a fuller acquaintance with the New Zealand species, 
which are presumably in the main of old types, to modify the views ex- 
pressed in my paper on the Australian T'ortricina (Proc. Linn. Soc. of New 
South Wales, 1881) as to the process of development of the Tortricida. 
The genus Harmologa and the additional species of Proselena furnish so 
strong a connecting link between their own group (or that of Acropolitis), 
and that of Tortriz and Cacoecia, that I see no other way of accounting for 
it, except on the supposition that this group is the oldest of the three 
principal ones, and that the groups of Dichelia, on the one hand, and of 
Tortriz, on the other, both sprang from it in diverging lines. The genus 
Prothelymna further supplies the nearest approach known to me in these 
regions towards the type from which this oldest group must have arisen. 
It is impossible to arrange a linear order so as to clearly show these rela- 
tions, but I think them quite apparent. The history of the special dis- 
tinguishing character of the Acropolitis group, the separation at origin of 
veins 8 and 4 of the hindwings, is thus satisfactorily made out; the group 
originates from the Chimabacchide, a small family specially characterized by 
this same structure, but in the Depressaride and Cicophoride, which are 
very extensive families, and the parents of the Chimabacchide, this character 
is entirely absent; the tendency to reversion in this particular has evidently 
been very strong, since in all three families of the Tortricina the character 
has disappeared from all but the oldest types. So marked is this result,
