Meyeick. — 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 Phycidce, but it is a true Crambus. 



Two specimens taken by Mr. E. W. Fereday in March near Lake Coleridge. 



Note. — Crambus sabulosellus, Walk., C. trivirgatus, Feld., and G. rotuellus, Feld., do 

 not belong to this family at all, and are therefore not referred to above.

II.— TOETEICINA. 



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 r 

 out of which (excluding Pcsdisca 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 Tortricina (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 Tortrix 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 

 Tortrix, 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 3 and 4 of the hindwings, is thus satisfactorily made out ; the group 

 originates from the Chimabacchidce, a small family specially characterized by 

 this same structure, but in the Depressarida and (Ecophoridce, which are 

 very extensive families, and the parents of the Chimabacchida, this cbaracter 

 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,
